From Sao Paulo, Brazil, Leane received her Doctor of Veterinary Medicine from Sao Paulo State University where she helped small dairy farms improve their profitability. Studies reported that the greatest proportion of treatments in dairy herds is due to clinical mastitis (Pol and Ruegg, 2007; USDA, 2007).
The most common intramammary treatment used was ceftiofur (60%), followed by cephapirin (Fig. Successful clinical mastitis treatments are influenced by a variety of factors including cow factors, pathogens, and treatment protocols (Hektoen et al., 2004). Conclusion: Cows treated with the herbal preparation, Phyto-Mast, at dry off had fewer new infections than no treatment. Hot topic: Milk and plasma disposition of thymol following intramammary administration of a phytoceutical mastitis treatment.
In this pilot study, we attempted to identify several active ingredients of Phyto-Mast®, a plant-based mastitis treatment used on organic dairy farms, and to quantify the product residue in milk and plasma after intramammary administration.
For over 30 years, QualiTech has been committed to conducting the research necessary to prove the efficacy of our SQM products.
When designing a mineral program the most important aspect impacting its benefit to the animal is bioavailability.
There are a number of factors, both animal and dietary, that can influence mineral bioavailability; however, one of the most insidious is dietary antagonism. In most bioavailability trials, researchers are looking for a response in absorption, retention, or tissue concentration of the target trace mineral.
This same increase in bioavailability can also be seen in trials evaluating immune function. Taken together, this research shows that by feeding a good, bioavailable trace mineral, like SQM, can have a positive influence on animal production, especially in situations where dietary antagonists are present. Prior to establishment of the essentiality of selenium (Se) for animals by Schwarz and Foltz (1957), this element was considered primarily as a toxic element.

Conventional antibiotic therapy is effective, but not an option for certified organic dairies. We developed an assay to quantify thymol (one of the active ingredients in Phyto-Mast®) in milk and plasma using gas chromatography and mass spectrometry (GC-MS). The clinical signs of selenosis in livestock were primarily found in the US in South Dakota and northern Nebraska where animals grazed plants which had accumulated toxic levels of Se. Factors such as somatic cell count previous clinical case, parity, stage of lactation, number of cases in the present lactation, pathogen causing mastitis, antimicrobial compound, and duration of treatment should be considered for treatment decisions to improve cure rate and decrease the antimicrobial usage on cases that would not respond for treatments. Although not as effective as conventional antibiotic therapy, Phyto-Mast could be a potentially useful dry treatment for organically certified dairies currently not using dry therapy. The first reports of the effects of Se deficiency in ruminants are the studies with calves (Muth et al., 1957) and lambs (Hogue, 1958) demonstrating that Se prevented nutritional muscular dystrophy.

Ruegg in Brazil, she applied for an internship at the University of Wisconsin and stayed to earn her MS degree in Dairy Science. As a model for dairy cows, 5 healthy, lactating alpine dairy goats were given 5?mL of Phyto-Mast® per udder half. Following these studies, there have been numerous studies showing the benefits of Se along with vitamin E in a number of health related aspects of dairy cattle and other species.Research is still in progress to determine additional forms and functions of Se in biological systems.
Currently, she is pursuing her PhD at the University researching factors that affect clinical mastitis and treatment outcomes. For 10 days following treatment, we analyzed blood and milk samples for thymol residues using GC-MS.

Evaluation of Stratification Factors and Score-scales in Clinical Trials of Treatment of Clinical Mastitis in Dairy Cows. Using thymol as a marker, Phyto-Mast® was detectable and quantifiable in plasma beginning with the 15-min post-treatment sample, but was no longer detectable in the 4-h post-treatment sample. It would appear that a difference for lactating animals could be justified based on difference in milk yield but growing animals should be similar. Recommendations for dietary levels needed should also include some assumptions on the bioavailability of the dietary source or form of Se. Factors Associated with Cure after Therapy of Clinical Mastitis Caused by Staphylococcus aureus.
DEFICIENCY SYMPTOMSIn the book, ‘The Role of Selenium in Nutrition’, Combs and Combs (1986) give an extensive review of all aspects of Se nutrition. In reviewing deficiency diseases of Se in cattle, they list nutritional muscular dystrophy, reproductive disorders in cows, cystic ovarian disease, Se-responsive unthriftiness, an anemia associated with the presence of Heinz bodies and a multifocal hepatic necrosis referred to as ‘sawdust liver’.
Clinical and bacteriological response to treatment of clinical mastitis with one of three intramammary antibiotics. The reproductive disorders include an increase in retained placenta, an increase in uterine infection following calving and a reduction in conception rate.One very important problem not discussed by Combs and Combs (1986) but which has received extensive discussion by others is the importance of Se and(or) Se and vitamin E in immune response and the reduction in the incidence of mastitis. Selenoprotein W has been shown (Yeh et al., 1997) to have a different distribution than glutathione peroxidase activity and may indicate a role for the form of Se in white muscle disease.
It is therefore very likely that Se could play an important role in some functions of dairy cattle which have not been demonstrated by research.
Arthur (1997) presented an excellent discussion on the possible role of Se in nonglutathione functions at last year’s Alltech Annual Symposium. DIETARY REQUIREMENT FOR SeSetting dietary requirements based solely on the Se content of the diet is difficult to do because many factors affect the bioavailability of Se. Combs and Combs (1986) state that bioavailability varies with the form of the Se compound, feedstuffs vary with respect to bioavailability, and other dietary factors can either enhance or decrease availability.

They also point out that currently only sodium selenite and sodium selenate can be legally used as supplemental sources in the US.Vitamin E is probably the dietary ingredient which has the most profound effect on dietary Se needs. The actions of Se and vitamin E are synergistic and many studies have demonstrated a reduction or elimination of deficiency symptoms where either compound is used.Weiss et al. Most of their studies use sodium selenite as the source of Se.Because of the possible effects of chronic Se toxicity, many diets are not supplemented to an optimum level.
Because acute selenosis results in diarrhea, respiratory distress and neurologic impairment (Blood et al., 1983) and chronic selenosis can result in ill thrift and lameness, oversupplementation must be avoided. In the southeast, where deficiency was most prevalent, blood Se content was either severely or marginally deficient in 40.0% of the herds that supplemented the cattle with Se. Their data demonstrated higher retention and lower excretion for the Se-enriched yeast than for sodium selenite. The yeast resulted in higher serum Se concentrations and milk Se was higher for the cows receiving the Se yeast. KENTUCKY STUDY WITH SEL-PLEX 50 SELENIUM YEASTPROCEDURESTwenty Holstein cows in an early stage of lactation (prior to 120 days of lactation) were assigned to a 2 ? 2 factorial arrangement of treatments with an additional negative control.
The basal diet did not have any supplemental Se.The trial was conducted over a 12 week period. Prior to this study the cows were receiving a diet with 0.3 ppm supplemental Se as sodium selenite. Blood and milk samples were collected at the end of this 2 week period to serve as base values. The next 10 weeks, all animals received the experimental diets containing the levels of supplemental Se listed above.The diet fed to all cows was a total mixed ration consisting of 50% forage, 10% whole cottonseed, and 40% concentrate based on dry matter content. While impaired immune response (susceptibility to mastitis) and reproductive problems are most frequently associated with Se deficiency, other problems can also occur. Either the use of enhancing factors such as vitamin E or the use of more bioavailable sources of Se such as Se yeast may be needed when limits are set on the amount of Se which can be added to the diet. Evaluating the efficacy of Seleniumenriched yeast and sodium selenite on tissue Selenium retention and serum glutathione peroxidase activity in grower and finisher swine. Effect of vitamin E and Selenium supplementation on incidence of clinical mastitis and duration of clinical symptoms. Effect of vitamin E supplementation in diets with a low concentration of Selenium on mammary gland health of dairy cows.
