Physiologic, health, and production responses of dairy cows supplemented with an immunomodulatory feed ingredient during the transition period
(Elsevier B.V., 2016-07-01)
This study compared physiological, health, and productive parameters in dairy cows supplemented or not with Omnigen-AF (OMN, Phibro Animal Health, Teaneck, NJ) during the transition period. Thirty-eight nonlactating, ...
Supplementing Ca salts of soybean oil to late-gestating beef cows: impacts on performance and physiological responses of the offspring
(2020-08-01)
This experiment compared the performance and physiological responses of the offspring from cows supplemented with Ca salts of soybean oil (CSSO) or prilled saturated fat (CON) during late gestation. Nonlactating, pregnant, ...
Effects of rumen-protected choline supplementation on metabolic and performance responses of transition dairy cows
(Amer Soc Animal Science, 2015-04-01)
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, ...

(2015-04-01)
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, ...
Effects of intravenous glucose infusion and nutritional balance on serum concentrations of nonesterified fatty acids, glucose, insulin, and progesterone in nonlactating dairy cows
(Elsevier B.V., 2010-07-01)
The objective of this study was to evaluate serum concentrations of nonesterified fatty acids, glucose, insulin, and progesterone in nonlactating dairy cows according to nutritional balance and glucose infusion. Ten ...
Effects of calcium salts of polyunsaturated fatty acids on productive and reproductive parameters of lactating Holstein cows
(Elsevier B.V., 2012-12-01)
Two experiments evaluated milk production, serum progesterone and insulin, and reproductive performance of lactating Holstein cows receiving or not receiving Ca salts of polyunsaturated fatty acids (PUFA), or receiving Ca ...
Effects of melengestrol acetate supplementation after fixed-timed artificial insemination on pregnancy rates of Bos indicus beef cows
(2017-12-01)
This experiment compared pregnancy rates in Bos indicus cows assigned to temporary calf weaning (TCW) or eCG administration during estrus synchronization, with or without melengestrol acetate (MGA) supplementation after ...
Effects of body weight loss on serum progesterone concentrations of non-lactating dairy cows
(Elsevier B.V., 2011-01-01)
The objective was to evaluate serum concentrations of nonesterified fatty acids (NEFA), cortisol, insulin, and progesterone (P4) of dairy cows maintaining or mobilizing body weight (BW). Eleven non-lactating, non-pregnant, ...

The objective was to evaluate serum concentrations of nonesterified fatty acids (NEFA), cortisol, insulin, and progesterone (P4) of dairy cows maintaining or mobilizing body weight (BW). Eleven non-lactating, non-pregnant, ...
Effects of excessive energy intake and supplementation with chromium propionate on insulin resistance parameters in nonlactating dairy cows
(Amer Soc Animal Science, 2014-02-01)
The objective was to compare insulin resistance parameters in cows with adequate or excessive energy intake as well as in cows with excessive energy intake receiving Cr supplementation as chromium propionate. Thirteen ...
