Fat-Feeding Practices for Lactating Dairy Cows
Supplementing cows with fat can have several beneficial effects. It usually increases the energy density of the diet as starch or fiber is replaced with fatty acids. If milk production is increased, then feed efficiency may be improved. Less heat may be produced in the rumen during digestion of fat-supplemented diets as fatty acids are not digested in the rumen. Less heat produced during digest...
متن کاملFeeding Dairy Cows When Corn Prices are High
Take Home Messages • The diversion of corn away from livestock to the production of ethanol is likely to increase in the future, so corn prices at the dairy farm are likely to remain high for the foreseeable future. Corn prices are about 50% greater now compared to 8 months ago. • Alternative grain sources high in starch are too expensive or unavailable in Florida. Hominy can partially replace ...
متن کاملImpacts of dietary fat level and saturation when feeding distillers grains to high producing dairy cows.
This experiment was conducted to determine whether increasing the net energy (NEL ) of a total mixed ration (TMR) with mainly unsaturated fat from corn distillers dried grains with solubles (DDGS) vs. rumen inert (RI)-saturated fat has similar impacts on animal performance. The experiment was an incomplete Youden square with three treatments and four 28-days periods, completed on a large commer...
متن کاملNutriDense corn grain and corn silage for dairy cows.
Twenty multiparous Holstein cows, 4 of them surgically fitted with ruminal cannulas, were used in a replicated 4 x 4 Latin square to compare the effects of whole-plant silage and grain produced from NutriDense (ND), leafy NutriDense (LND), or a conventional yellow dent (YD) hybrid on ruminal fermentation, total tract nutrient digestibility, and performance of lactating dairy cows. On a DM basis...
متن کاملFeeding Fatty Acids to Dairy Cows for Fertility
The essentiality of certain amino acids and certain fatty acids was established for growing rats at about the same time. W.C. Rose at the University of Illinois in the early 1930’s identified 10 essential dietary amino acids for rats. Soon thereafter, these same essential dietary amino acids were confirmed experimentally in growing nonruminant livestock. The fatty acids, linoleic acid (C18:2) a...
