Effect of live yeast culture supplementation on rumen fermentation in lactating dairy goats
Addition of yeast to dairy cow diets might be beneficial for milk production. However, data concerning goats are scarce, especially on the role of yeast on rumen metabolism. Thus, four goats, according to a cross-over design, received successively two diets with or without living yeasts. Animals were in mid-lactation and received a total mixed diet ad libitum. For the yeast diet (Y), each goat ...
متن کاملRisk Factors of Seven Groups of Health Disorders in Iranian Holstein Cows
Objective: The cows that don’t have access to sufficient energy in their ration can get sickness. Milk production has a high priority in metabolism of dairy cows so lactating cows are more prone to get sick This can ruin all the benefits of higher milk yield because of the higher prevalence of the disorders. Methods: Data for this research had gathered from a herd with 1600 Holstein cattle in E...

متن کاملInvited review: palmitic and stearic acid metabolism in lactating dairy cows.
Energy is the most limiting nutritional component in diets for high-producing dairy cows. Palmitic (C16:0) and stearic (C18:0) acids have unique and specific functions in lactating dairy cows beyond a ubiquitous energy source. This review delineates their metabolism and usage in lactating dairy cows from diet to milk production. Palmitic acid is the fatty acid (FA) found in the greatest quantit...
متن کاملRecombinant bovine somatotropin's effects on patterns of nutrient utilization in lactating dairy cows.
The discussion of effects of recombinant bovine somatotropin (rbST) administration on the metabolism of lactating dairy cows presented is divided into two parts: short term and long term. Short-term effects are evident during the initial period of treatment when milk production is increased but feed intake has not yet increased. During this period body reserves are mobilized to support the high...
