Effects of rumen-protected choline supplementation on metabolic and performance responses of transition dairy cows.
The objective of this experiment was to compare metabolic and milk production parameters in dairy cows supplemented and nonsupplemented with rumen-protected choline (RPC) during the transition period. Twenty-three nonlactating, multiparous, pregnant Holstein cows were ranked by BW and BCS 21 d before expected date of calving and immediately were assigned to receive (n = 12) or not receive (cont...
متن کاملEffect of a rumen-protected niacin product on lactation performance by dairy cows during summer in Wisconsin
The objective of this study was to evaluate the effect of a rumen-protected niacin product (NiaShure, Balchem Corp., New Hampton, NY) on lactation performance by dairy cows during the summer in Wisconsin. Eighty lactating dairy cows (63 ± 29 DIM) were used in a 10-wk lactation trial (a 2-wk pretreatment covariate period followed by an 8-wk treatment period). Cows were stratified by breed, parit...
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 کاملFeeding Rumen-Protected Choline to Transition Dairy Cows
Choline [(CH3)3N+CH2CH2OH], also known as trimethyl ethanolamine, is an essential component of mammalian diets as it is required for normal function of cells. It was discovered by Andreas Strecker in 1862, but it remained unrecognized as an essential nutrient for humans until 1998, when dietary reference intakes were established. Choline was initially determined to be essential in the preventio...
متن کاملEffect of feeding rumen-protected methionine on productive and reproductive performance of dairy cows
The objectives of this study were to evaluate the effects of daily top-dressing (individually feeding on the top of the total mixed ration) with rumen-protected methionine (RPM) from 30 ± 3 until 126 ± 3 Days in milk on productive and reproductive performance in lactating dairy cows. A total of 309 lactating dairy Holstein cows (138 primiparous and 171 multiparous) were randomly assigned to tre...
