Effects of rumen-protected γ-aminobutyric acid on feed intake, lactation performance, and antioxidative status in early lactating dairy cows.
The objective of this study was to investigate effects of rumen-protected γ-aminobutyric acid (GABA) on dry matter intake, milk performance, and serum metabolites in Chinese Holstein lactating cows. Thirty-nine multiparous cows were blocked based on days in milk (60 ± 6.3 d; mean ± SD) and milk production (30.9 ± 4.17 kg; mean ± SD), and were randomly assigned to 1 of 4 treatments, with rumen-p...
متن کاملEffects of Rumen-Protected Methionine on Dairy Performance and Amino Acid Metabolism in Lactating Cows
Problem statement: Free Met as one of the most limiting AA in dairy cows would be mostly degraded in the rumen. This study was to determine the effect of different levels of RumenProtected Met (RPMet) on dairy performance and serum amino acid metabolism. Approach: Thirtysix Holstein cows in similar condition were randomly assigned to six experimental treatments with six replicates each. Levels ...
متن کاملEffects of a rumen-protected form of methionine and a methionine analogue on the lactation performance of dairy cows
The objective the present study was to determine the influence of a supplemental methionine analogue, the isopropyl ester of 2-hydroxy-4-(methylthio)-butanoic acid, commercially available as MetaSmartTM, on lactation performance, particularly milk protein production. The effects of this preparation were compared with those of a rumen-protected form of methionine, marketed as SmartamineTM M. Exp...
متن کاملthe effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows
پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Effects of Feeding Rumen Protected Choline and Vitamin E on Milk Yield, Milk Composition, Dry Matter Intake, BodyCondition Score and Body Weight in Early Lactating Dairy Cows
Twenty four primiparous and multiparous Holstein cows on early lactation, beginning five weeks postpartum, were used for four weeks to investigate the effects of supplemention of rumen-protected choline (RPC) or vitamin E on milk yield, milk composition, dry matter intake, body condition score and body weight. The cows were randomly assigned to one of the following treatments: I)no supplement (...
