Effect of Rumex Sc on Ruminal Fermentation, Blood Metabolites and Performance of Lactating Dairy Cow
This study investigated the effect of Rumex Sc (commercial product which includes of Saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. Animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). Additionally, Rumex Sc was included in the experimental d...
متن کاملEffect of amount and ruminal degradability of soybean meal protein on performance of lactating dairy cows.
Twenty-eight Holstein cows (4 with ruminal cannulas) were blocked by days in milk into 7 groups and then randomly assigned to 1 of 7 balanced 4 x 4 Latin square diet sequences. The diets contained [dry matter (DM) basis] 20% alfalfa silage, 35% corn silage, and 45% concentrate mainly from high-moisture corn and soybean meal. Diets differed in crude protein (CP) content and source of protein sup...
متن کاملThe Effect of Different Levels of Sesame Wastes on Performance, Milk Composition and Blood Metabolites in Holstein Lactating Dairy Cows
The objective of this study was to determine the effect of different levels of sesame wastes (SW) on performance, milk composition and blood metabolites in lactating dairy cows. In this order, eight multiparous Holstein dairy cows were used in a replicated 4×4 Latin square design in four periods of 21 days. Treatments were control (no Sesame meal supplementat...

متن کاملEffect of dietary crude protein level and degradability on ruminal fermentation and nitrogen utilization in lactating dairy cows.
The objectives of this experiment were to investigate the effects of two ruminally degradable protein (RDP) levels in diets containing similar ruminally undegradable protein (RUP) and metabolizable protein (MP) concentrations on ruminal fermentation, digestibility, and transfer of ruminal ammonia N into milk protein in dairy cows. Four ruminally and duodenally cannulated Holstein cows were allo...
