Influence of yeast culture on feeder calves and lambs
Article Abstract:
Supplementary yeast culture does not affect the health or performance of normal calves. Moreover, sick calves fed the yeast culture recovered after fewer days of antibiotic therapy than the sick calves fed the control diet. Calves on yeast dietary supplements had heavier weights than the controls after intranasal challenge with bovine rhinotracheitis virus. Lambs fasted for three days had more nitrogen, zinc and iron balance when fed the yeast culture. Thus, the beneficial effects of dietary yeast culture on stressed calves and lambs may be due to improved nitrogen and mineral metabolism.

Influence of postfast dietary crude protein and phosphorus content on nitrogen, phosphorus, calcium, and magnesium repletion in sheep
Article Abstract:
Results of an experiment on sheep indicated that realimentation diet has no significant influence on serum concentrations of inorganic calcium, phosphorous, magnesium, alkaline phosphatase or free fatty acids. Impact of postfast crude protein and phosphorus content in diet on magnesium, phosphorus, calcium and nitrogen store repletion in sheep was identified. Under the four x four experimental design, lambs were fasted for three days and then fed one of the four pre-determined isoenergetic realimentation diets.

Supplemental chromium for stressed and growing feeder calves
Article Abstract:
One hundred eight Charolais-crossed calves were distributed among four treatment groups during a 28-day stress period. The calves were fed with corn silage and supplemental chromium were added to test animals. It was found out that market-transit stress is correlated to deficiency in chromium and that supplementation will decrease serum cortisol and improve immune response. It also promotes improved performance during stress and reduced need for preventative or therapeutic antibiotic drugs.
