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 کاملThe feeding value of corn distillers solubles for lactating dairy cows.
Fifteen Holstein cows (10 multiparous and 5 primiparous) in early to mid lactation (79.3 +/- 9.2 d in milk) were used in a multiple 5 x 5 Latin square design with 4-wk periods to evaluate and compare the use of condensed corn distillers solubles (CCDS) and dried distillers grains with solubles (DDGS) in the total mixed ration. The forage portion of the diets was kept constant at 27.5% corn sila...
متن کاملEffect of Feeding Quickly Degradable Nitrogen on the Development of Ovarian Follicles in Lactating Dairy Cows
The objective of this study was to examine the effect of an excess intake of quickly degradable nitrogen (QDN) on ovarian follicle development. Twenty lactating dairy cows were fed mixed silage and concentrates twice daily. The control diet was a typical ration for high producing dairy cows in the United Kingdom (crude protein (CP)=17.5%; metabolizable energy (ME)=11.8 MJ/kg DM). The cows were ...
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...
