From there, several studies have been made and continue being developed with the use of probiotics.
The emergence of antibiotic-resistant pathogens in humans is driving efforts to find commercially viable substitutes for antibiotics frequently used in the production of food animals, including poultry. While much progress has been made, much work remains, according to a recent article in Poultry Science, a journal published by the Poultry Science Association (PSA). Cobb Asia has appointed Dr Raul Elias Lopez as technical service manager focusing on broiler production.
Glutamine-enriched diets have been linked with favorable intestinal effects including structure maintenance of gut barrier against bacteria attacks and enterocyte differentiation.
From a poultry production perspective, the maintenance, development and health of GIT are fundamental, since GIT possesses the functions of food content storage, secretion digestion, and absorption of nutrients.
On the other hand, delaying access to feed and water has been documented to increase susceptibility to pathogens and cause weight loss, leading to poorly starting flocks with reduced weight gains and mortality [9-11]. Alternatively, increasing socio-political concerns with antibiotic usage have led to investigations of potential alternatives for food safety and growth promotion.
The present studies hold their relevance and importance, considering the fact that the feed costs represents 70 to 80% of the poultry production and the integrity of the epithelial cells of the mucosa, hence ensured good performance and production, is dependent of feed and feed supplements. Day-of-hatch, off-sex broiler chickens were obtained from CobbVantress (Siloam Springs, AR, USA) for all the trials mentioned below. The challenge organism used in all experiments was poultry isolate of Salmonella enterica subspecies enterica serovar Typhimurium (ST).
This experiment evaluated the effect of 1% dietary Gln supplementation for 6 days associated with FM in the drinking water on ST cecal colonization and in vitro nitric oxide production. This experiment evaluated the effect of 1% dietary Gln supplementation for 6 days associated with BS spores (PHL-NP-122) on ST cecal colonization and in vitro nitric oxide production. This experiment evaluated the effect of 0.5% Gln supplemented with perinatal supplement on growth performance and intestinal morphology in broiler chickens during 14 days. In experiment one, chickens were humanely killed by CO2 asphyxiation; ceca-ceca tonsils were aseptically removed to culture and enumerate Salmonella. A novel explant culture method for rapid quantification of nitrite as an inflammatory marker developed in our lab [Kallapura et al., 2013, Submitted for Publication] was employed here. The Greiss reaction assay, which colorimetrically quantifies nitrite, was used to measure the nitrite accumulated over time in the culture medium, which served as an indirect measure of NO produced by the explants. For enteric morphometric analysis, birds on the designated evaluation day were euthanized, and ileum and duodenum samples were collected (n=5).
The results of the effect of 10% Gln supplementation associated with FM in the drinking water on ST colonization in broiler chickens from experiment 1 are summarized in table 2. Table 2: Effect of 10% glutamine (Gln) supplementation associated with FloraMax (FM) in the drinking water on Salmonella Typhimurium (ST) colonization in broiler chickens from experiment 1. The effect of 1% dietary Gln supplementation associated with FM in the drinking water on ST colonization at 6 days of age in broiler chickens from experiment 2 are summarized in table 3.
The effect of 1% dietary Gln supplementation associated with PHL-NP-122 on ST colonization at 6 days of age in broiler chickens from experiment 3 is summarized in table 4. Table 3: Effect of 1% dietary glutamine (Gln) supplementation associated with FloraMax (FM) in the drinking water on Salmonella typhimurium (ST) colonization at 6 days of age in broiler chickens from experiment 2. Table 4: Effect of 1% dietary glutamine (Gln) supplementation associated with Bacillus subtilis spores (PHL-NP-122) on Salmonella Typhimurium (ST) colonization at 6 days of age in broiler chickens from experiment 3.
Table 5: Effect of Glutamine (Gln) with perinatal supplement (EB) on body weight (BW) and performance of broiler chickens from experiment 4. The effect of 0.5% Gln with perinatal supplement on body weight and performance of broiler chickens from experiment 4 are summarized in Table 5. Glutamine is a captivating amino acid that constitutes significant concentrations of muscles and plasma, and represents about 50 to 80% of the total free amino acid in the body [1,4,37]. In the present study, the supplementation of 10% Gln with probiotic culture in the drinking water had a significant reduction on ST colonization in the ceca, but this effect was not synergistic (Table 2).
On the other hand, a fasting period of 24 to 72 h after hatch is a common practice in commercial poultry operations [19] due to variation in hatching time and management in the hatchery. The XIII International Seminar on Avian Pathology and Poultry Production, organized by the Colombian Association of Poultry Veterinarians (AMEVEA) and hosted by the University of Georgia on March 24-28, will draw hundreds of poultry veterinarians from Latin American countries.
Cellulitis, a leading cause of carcass condemnation in broilers, represents significant economic losses for poultry producers. Fumonisins - a group of toxic and carcinogenic fungal metabolites commonly found in corn (maize) and its by-products - pose a significant threat to swine production.
Achieving better growth rates or improved efficiency relies on good gut performance in aquaculture species. A new technology promises to revolutionize the simultaneous detection of mycotoxins and greatly expand our scientific knowledge.
While genetic improvement has been the main driver for improved prolificacy of sows and production of high lean progeny, better nutrition offers a way for further gains. Phytogenic feed additives (PFAs) are effective in improving the antioxidant status of animals, as confirmed by an elevated antioxidative status in blood plasma, meat and the intestinal tract. Consumer awareness of sustainable aquaculture production has led to increased interest in certification for sustainable aquaculture practices. Maximizing lifetime profit per cow a€“ a good measure of a dairy operationa€™s overall profitability a€“ requires diligence at all stages, starting at birth. Mycotoxins are always present in animal feeds, although at varying levels, and affect different systems such as the gastrointestinal tract (GIT) and visceral organs. We know that behind each and every success is a team of highly motivated and talented individuals.
By offering an open corporate culture with room for professional growth and career development, we trust that growing a business is first and foremost about nurturing high caliber talents.
The history of antibiotic use in animal production and alternative strategies that work are reviewed by Sandra Avant of the USDA Agricultural Research Service (ARS) in the latest issue of Agricultural Research.
Food supplements, probiotics, and phytonutrients have been shown to help fight some poultry diseases.
In a milking parlor at Aimes, Iowa, molecular biologist John Lippolis collects milk samples for test to see whether vitamin D reduces the severity of mastitis. Animals that have recently been weaned are particularly susceptible to bacterial infections and may benefit a lot from the nitro and chlorate treatments.
Proposed interactions between competitive exclusion products, probiotics or immunostimulants, and avian intestinal immunity. IntroductionIn face of the current debate about the use of antibiotics as growth promoters, due to the probable relationship with resistance to antibiotics used in human medicine, the presence of antibiotic residues in products of animal origin intended for human consumption and the emergent demand from consumer market for products free from additive residues, it was necessary to search for alternative products that could replace antibiotics used as promoters, without causing losses to productivity or product quality. Inconsistent results from the use of probiotics in animal production have been a constraint for the promotion of their use.
Michael Hume, a researcher at the United States Department of Agriculture, Agricultural Research Service, in College Station, Texas, at a PSA symposium on the potential impact of reduced antibiotic use and the roles of alternatives to antibiotics in antibiotic-free broiler production.
Mannan oligosaccharides are derivatives of yeast cell walls, while fructo-oligosaccharides can be extracted from fruits, vegetables, and grains. Although post hatch, immaturity of the GIT in the first week is a limiting factor, early nutrition has shown to be an alternative to alleviate the adverse performance effects of post-hatch starvation.
However, several researches has shown that Gln may be a conditionally essential amino acid in maintaining gut integrity and reducing inflammation [1-5]. It is responsible for mucosa structure maintenance, through mucin synthesis and the maintenance of a barrier against bacteria attacks, in addition to promoting the maturity and integrity of the intestinal flora associated with the immune system.


Early nutrition has been widely studied in poultry, and it has been shown that the use of early feeding supplements alleviates the adverse performance effects of post-hatch starvation [12-15], as well as stimulates yolk utilization [16], intestinal maturation [10], development of homeothermy [17,18], and retain passive immunity [19].
Both live and spore based probiotics have earned tremendous attention as a viable control of enteric pathogens in this regard.
These studies were carried out with multiple objectives of evaluating the influence of nutrition and combinational effects of Gln supplementation in concert with FloraMax-B11 (FM), PHL-NP-122 and EB on Salmonella typhimurium colonization. All animal handling procedures were in compliance with Institutional Animal Care and Use Committee at the University of Arkansas. BDH 4514-1KGP, VWR West Chester, PA 19380) supplementation associated with FM in the drinking water on ST cecal colonization. Briefly, samples were placed in 10 mL of Tet for enrichment and incubated at 37 °C for 24 hours. Briefly, the entire ileum was aseptically removed, cleaned by infusing sterile 0.9% saline through the ileal section to remove all the ingesta. The assay was carried out in a 96 well microtitre plate to which 100 µL of culture supernatant from the explant culture (at 3, 6, and 12 h) was added in triplicates, followed by an equal volume of Greiss reagents. A 1-cm segment of the midpoint of the duodenum and the distal end of the lower ileum from each bird was removed and fixed in 10% buffered formaldehyde for 48 h.
At 24 h and 48 h significant BWL were observed with control and EB only groups when compared with the group that received EB + Gln. Since its structure contains two mobilizable N groups Gln is involved in transportation and exchange of N in the cells, as well as participate in important metabolic pathways [1,5]. However, dietary supplementation of 1% Gln associated with a lactic acid bacteria probiotic in the drinking water (Tables 3), or in the diet throw a DFM in form of spores of Bacillus subtilis (Table 4) had a significant and synergistic effect on the reduction of Salmonella Typhimurium in the ceca. This delay in start of feed intake has been shown to negatively affect yolk utilization [52], gastrointestinal development [15], slaughter weight [53] and breast meat yield [54,55].

Economic losses due to heat stress in the US swine industry alone are estimated at US$316 million annually. With global activities spanning the Americas, Europe, Africa and Asia-Pacific, we are at the forefront of our field. Schematic representation of the crosstalk between probiotic bacteria and the intestinal mucosa. Effectiveness of probiotics in the prevention of Salmonella colonization in broiler chicken. An alternative is the use of probiotics, which are products made from living micro-organisms or their L-forms (without cell wall). Variations in the efficacy of probiotics can be due to the difference in microbial species or micro-organism strains used, or with the additive preparation methods (Jin et al., 1998a).
In addition, both live and spore based probiotics have earned tremendous attention as a viable control of enteric pathogens. Glutamine-enriched diets have been linked with favorable intestinal effects including maintenance of gut barrier function and enterocyte differentiation [6]. Because Gln is the main metabolite that nourishes the enterocytes, effect of glutamine supplementation on reconstitution of the intestinal mucosa, after some damage, has been investigated in various studies [2].
These gut functions begin with hatching and has to be maintained throughout the production pyramid.
In this concern, Early Bird (EB), a natural hydration and nutrition supplement for neonatal broilers and poults, is extensively used to promote instinctive feeding of birds, that leads to a rapid onset and increased early weight gains that will eventually be maintained throughout the bird's lifetime [20]. Laboratory and field research conducted by our laboratory with a defined lactic acid bacteria (LAB) probiotic, FloraMax-B11 (FM) have proved extremely influential in accelerated development of normal microflora and reduction in Salmonella colonization, in commercial poultry [21-28]. In all experiments, diets were fed in mash form, and were formulated to exceed National Research Council [32] estimated nutrient requirements. For the present studies, 100 µL of SE from a frozen aliquot was added to 10 mL of tryptic soy broth (Catalog no. A small number of chickens (n=20) were humanely killed on arrival, ceca-cecal tonsils and liver and spleen were aseptically removed, cultured in Tet and confirmed negative for Salmonella by plating the samples on to selective BGA with NO. A small number of chickens (n=20) were humanely killed on arrival, ceca-cecal tonsils and liver and spleen were aseptically removed, cultured in Tet and confirmed negative for Salmonella by plating the samples on to selective BGA with NOV. Each of these intestinal segments was embedded in paraffin, and a 5-μm section of each sample was placed on a glass slide and stained with hematoxylin and eosin for examination under a light microscope.
This reduction was associated with a significant reduction on NO produced in the explant tissues as compared with the control group. As in the previous experiment, this reduction was also associated with a significant reduction on NO produced in the explant tissues as compared with the control group. These differences were maintained at 7 and 14 days of evaluation, with significantly higher BWG seen in the group treated with EB + Gln. This amino acid is also a key component in the function and structure of the intestinal mucosa since it is involved in mucin synthesis as well as maintaining the integrity of the gut microbiome [1,3,4,6,34], which has a profound impact in digestive physiology [21,38-40], as well as innate and acquire immunity [41-44]. This reduction was associated with a significant reduction of nitric oxide produce in the explant of ileum samples (Table 3 and 4). Bailey will examine the role of intestinal microflora in maintaining enteric health, and how products such as probiotics can benefit the intestinal tract. The micro-organisms included as probiotics are usually assumed to be non-pathogenic components of the normal microflora, such as the lactic acid bacteria. However, other factors can justify the variations in the results of probiotic use in poultry, such as origin species, probiotic preparation method, survival of colonizing micro-organisms to the gastrointestinal tract conditions, environment where the birds are raised, management (including the application time and application route of the probiotic), the immunologic status of the animals, the lineage of the poultry evaluated, as well as age and concomitant use or not of antibiotics.
Glutamine has also been the focus of many studies in physiology and medicine due to its important pleiotropic roles in metabolism and tissue homeostasis. In addition, Gln is an essential substrate in the construction of the passive barrier of mucin to bacteria because it is necessary for the synthesis of N bases and amino sugars of the extracellular matrix, N-acetylglucosamine and N-acetylgalactosamine, and for the glycosylation of mucins [1]. Posthatch the gut maturation process begins and this is a critical point in determining the poultry performance. More recently, we have confirmed that selected heatresistant spore-forming Bacillus species, PHL-NP-122, can markedly reduce Salmonella and Clostridium in poultry when administered in very high numbers [29-31]. These studies also supports numerous trials which have previously tested individual positive effects of Gln, EB, FM and PHL-NP-122, on growth performance by rapid development of intestinal morphology in broiler chickens [20-31]. The common starter diet was a typical corn soy bean meal diet (chemical analysis of nutrients is presented in Table 1). 22092, Sigma) and incubated at 37°C for 8 h, and passed every 8 h to ensure that all bacteria were in log phase. A small number of chickens (n=20) were humanely killed on arrival, ceca-cecal tonsils and liver and spleen were aseptically removed, cultured in tetrathionate enrichment broth (Tet, Catalog no.
Ileal sections (0.5 cm2 ) were made using a sterile surgical blade and placed in a 24 well culture plate. As if these functions were not important enough, Gln is the principal energetic fuel for cells that has a rapid proliferation such as enterocytes, lymphocytes and other cells involved in inflammation [2,3,7,45]. Quantifying nitrite, a metabolite of nitric oxide (NO), is a wellestablished marker for the production of reactive nitrogen species and an indirect measurement for inflammation. The immediate post-hatch period is critical for intestinal morphological development in order to digest feed and assimilate nutrients [57,58].


Probiotic bacteria can also enhance intestinal barrier function by (5) increasing mucus production (Adapted Ng et al., 2009). However, there is good evidence that non-pathogenic variants of pathogenic species can operate in much the same way as traditional probiotics. Thus, the aim of this review is to discuss the use of probiotics in poultry, with emphasis on the type of probiotic and micro-organisms used, action mechanism and its relation with the variations on the results of poultry survey.2. Glutamine serves as an essential metabolic precursor in nucleotide, glucose and amino sugar biosynthesis, glutathione homeostasis and protein synthesis [3]. Gln has direct action in the elimination of free radicals by being a precursor of glutathione synthesis [6].
The first two weeks of post hatch are even critical and represent approximately 30% of the useful life of the bird, considering a 6 week production cycle. For experiments 2 and 3, the diet with glutamine was similar to the common starter diet but was supplemented with 1% Gln. Bacillus subtilis (BS) spores (PHL-NP-122) previously identified as potential probiotic or direct-fed microbial (DFM) candidate [31] was used in the present study. 210420, Becton Dickinson, Sparks, MD) and confirmed negative for Salmonella by plating the samples on to selective BGA with NOV. One h post challenge, groups 3 and 4 received FM in the drinking water, while group 1 acted as positive control for ST. Twelve chickens from control or treated groups were humanly killed and cultured at six days of age (24 h post ST challenge), for ST enumeration and explant samples for nitric oxide determination as explained later. Later, the cecal samples were enriched in double strength Tet and further incubated at 37 °C for 24 hours. Care was taken in placing the tissue explants, with the serosa facing down and in contact with the well bottom and the mucosa facing up, exposed to the media components.
Louis, MO) in water and incubated further for a visible colored reaction to develop and measured at 540 nm.
Although not significant, over all, the EB group had a numerical improvement in performance with about 12 g heavier than that of non-treated control group (Table 1).
The innate immune response is modulated through the recruitment of various cellular components upon pathogen exposure. Decreased intestinal development in chicks fasted for 36 to 48 hours post-hatch have been extensively reported by several investigators [9-11,20,59,60]. For example, avirulent mutants of Escherichia coli, Clostridium difficile, and Salmonella Typhimurium can also protect against infection by the respective virulent parent strain (Fuller, 1995). Type of probiotic and micro-organisms usedThere are several types of probiotics available in the market to be used in poultry, with a range of micro-organisms present and, therefore, with different metabolic activities and action modes. Presence of two mobilizable Nitrogen (N) groups in its structure, Gln can function as a vehicle for the tissue exchange of N and perform a crucial role in several important metabolic pathways. Gln is also considered as an immunonutrient, because of its capability of upregulating or downregulating immune responses to a pathogen or disease condition and may therefore reduce pathogen levels.
Concentrations of ST were determined retrospectively by serial dilution and further plating on Brilliant Green Agar (BGA, Catalog no. Age appropriate environmental temperatures were maintained and supplemental heat lamps were provided for each pen.
Circular metal meshes measuring approximately 7.5mm in radius with 3mm height were used to keep the floating explants in place.
The Greiss reaction was based on a two-step diazotization reaction in which acidified nitrite (phosphoric acid) produces a nitrosating agent which reacts with sulfanilic acid to produce a diazonium ion. Ten replicate measurements for each variable studied, were taken from each sample and the average values were used in statistical analysis. The effect of 0.5% Gln with perinatal supplement on morphological development of mucosa in duodenum of broiler chickens is summarized in Table 6.
Heterophils, monocytes and macrophages are at the forefront of pathogen recognition, and work in combination with effector leukocytes to initiate an immune response. In the present study, chicks that received 0.5% Gln with a perinatal supplement showed significantly less body weight loss during at 24 h and 48 h under simulated shipping period of 48 h and were significantly heavier at 7 and 14 days (Table 5), and these changes were associated with the significant increased VH, VW, and VS observed in the groups treated with EB only or EB + Gln, when compared to non-treated control group at 24 h. Also, they present variations as to the capacity of colonizing the intestine or not, which justifies variations on the results of their use.Bacillus, Bifidobacterium, Enterococcus, E. As an immunonutrient, Gln is important for promoting the integrity and maturation of intestinal microflora associated with the immune system, for enhancing mucin synthesis to maintain intestinal mucosa structure, and for reinforcing the epithelial barrier against bacterial attacks [7].
One h post challenge, groups 2, 3 and 4 received their treatment in the drinking water, while group 1 acted as positive control for ST.
Chickens were provided ad libitum access to water and a balanced un-medicated corn-soybean diet meeting or exceeding the nutrition requirements of poultry recommended NRC [32]. These meshes were made of steel 316 L, the same material used in construction of fermenters and bioreactors. This ion intermediate was then coupled with N-(1-naphthyl) ethylenediamine to form the chromophoric azo-derivative whose absorbance was measured at 540 nm. Villus length (VL) was measured from the top of the villus to the top of the lamina propria. Significantly increased VH, VW, and VS were observed in the groups treated with perinatal supplement only or 0.5% Gln and perinatal supplement, when compared to non-treated control group at 24 h. Studies investigating the role of heterophils, monocytes, and macrophages begin with quantification of reactive nitrogen species (RNS), reactive oxygen species (ROS), along with cytokines and chemokines [46].
The trend of significant and in some cases numerically, morphometric changes were observed throughout the study in duodenum samples (Table 6). In their experiments, the authors observed that the intestinal contents of normal adult birds, orally administered to chicks with one day of age, altered their sensitivity to infection by Salmonella spp.
Hence the immaturity of the GIT in the first week post hatch is a limiting factor, since major gut transitions like increase in absorption capacity with a relative increase in the area of absorption through the longitudinal growth of the intestine, and increase in the height of the villi, proper secretion of enzymes, are events yet to happen.
Twenty chickens from control or treated groups were humanly killed and cultured at 24 h, for ST recovery in ceca-cecal tonsils and enumerated as explained later. The material is non-reactive, non-additive, non-absorptive and non-corrosive and hence a safe choice to be used with a culture medium.
Though rapid clearance of pathogens has been attributed to ROS (oxidative stress) rather than RNS (nitrosative stress), nitrosative stress is important in chronic and prolonged exposure. However, even those belonging to the same species can have different strains and even these different strains from the same species can have different metabolic activities.
Considering the fact that the feed costs represents from 70 to 80% of the poultry production and the integrity of the epithelial cells of the mucosa, hence ensured good performance and production, is dependent of feed and feed supplements, these studies hold their relevance and importance as beneficial in more than one aspect to the poultry industry. In this regard, we suggest and hypothesize that the stimulation of the GIT by different substrates, soon after hatching, can accelerate its development. Recorded body weights (BW) were then used to determine either body weight loss (BWL) at 24 h and 48 h or body weight gain (BWG) at 7 and 14 days of age.
The sequential progression from a predominant oxidative stress to the production of nitrosative clearance could optimize the reduction in microbial burden along with minimizing immune pathological consequences of host inflammatory response [47,48]. Hence, quantifying metabolites of nitric oxide (NO), such as nitrite or expression of inducible nitric oxide synthase (iNOS), have been the principle for investigating the role of RNS during host inflammatory responses. The quantification of NO in the ileal explants from experiments 2 and 3 provided a suitable model for inflammation (Table 3 and 4), which potentially mimics in vivo intestinal conditions that rapidly detected NO (6 h), at a greater magnitude than other cell culture methods [49-51] .
