Effects of rumen-protected choline supplementation on milk production and choline supply of periparturient dairy cows.
The objective of the present study was to determine the effects of rumen-protected choline (RPC) supplementation on body condition, milk production and milk choline content during the periparturient period. Thirty-two Holstein cows were allocated into two groups (RPC group - with RPC supplementation, and control group - without RPC supplementation) 28 days before the expected calving. Cows were...
متن کاملEffect of rumen-protected choline on performance, blood metabolites, and hepatic triacylglycerols of periparturient dairy cattle.
The effects of a dietary supplement of rumen-protected choline on feed intake, milk yield, milk composition, blood metabolites, and hepatic triacylglycerol were evaluated in periparturient dairy cows. Thirty-eight multiparous cows were blocked into 19 pairs and then randomly allocated to either one of 2 treatments. The treatments were supplementation either with or without (control) rumen-prote...
متن کاملEffects 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 کاملUpdate on Rumen-protected Choline in Dairy Cow Nutrition
Choline is a quasi-vitamin that has a variety of functions in mammalian metabolism. Its major functions are as the predominant phospholipid contained in the membranes of all cells in the body (as phosphatidylcholine), a component of the neurotransmitter acetylcholine, and as a direct precursor to betaine in methyl metabolism. It is beyond the scope of this paper to review these functions in dep...
متن کاملRumen-protected choline: A significance effect on dairy cattle nutrition
Choline is a vitamin-like substance it has multi-function in animal production, reproduction, and health. The transition period is most crucial stage in lactation cycle of dairy cows due to its association with negative hormonal and energy balances. Unfortunately, unprotected choline easily degrades in the rumen; therefore, choline added to the diet in a rumen-protected form. The use of rumen-p...
