ASAS/ADSA Ruminant Nutrition: By-Products, Fiber, and Silages
This experiment evaluated the effect of feeding dairy cows with cottonseeds containing BollGard r (Cry1Ac) and BollGard r II (Cry1Ac and Cry2Ab), Roundup Ready r (CP4 EPSPS) and control non-transgenic cottonseed on dry matter intake, milk yield and milk composition. Twelve lactating multiparous Argentinean Holstein cows weighing 570 kg (BW) were used in a 4x4 Latin square design, with 3 squares...
متن کاملRuminant Nutrition: Feed Additives
Feed additives are largely used in beef cattle diets to improve performance and reduce risks of nutritional disorder diseases like acidosis and timpanism. However, some countries tend to ban the use of ionophore in animal nutrition due to the risk of resistance of some microorganisms. Therefore, alternatives to non-antibiotic additives must be studied. The objective of this work was to investig...
متن کاملRuminant Nutrition: Dairy: Feed Additives
Multiparous Holstein cows (n = 60) were used to determine effects of trace mineral source on oxidative metabolism, subclinical endometritis, and performance of transition cows. After a 1-wk preliminary period, cows were assigned randomly to one of 3 topdress treatments from 21 d before expected calving through 84 d post calving: 1) Inorganic sources based upon sulfates of Zn, Cu, and Mn (ITM); ...
متن کاملInhibition of enzyme activities by free fatty acids.
The inhibition of several enzyme activities by free fatty acids has been examined. The inhibition of rat liver microsomal linolenate-activating enzyme activity by linolenate was found to be due to the inactivation of enzyme by substrate fatty acid. Stearoyl coenzyme A was also found to inhibit linolenate-activating enzyme. Likewise, microsomal glucose 6-phosphatase was inhibited by oleate; the ...
متن کاملInhibition of enzyme activities by 12-keto oleic acid.
The effect of the long chain keto acid, which is one of the secondary products from oxidative deteriolation of lipids, on the enzyme activity was investigated in vitro. Cholinesterase and succinate dehydrogenase were inhibited more effectively by 12-keto oleic acid than by linoleic acid, whereas the inhibition of trypsin by linoleic acid was greater than that caused by 12-keto oleic acid. This ...
