Supplementary Feeding of Dairy Cows to Increase Milk Production
Milk production systems in Eastern Australia vary from grazing improved pastures and fodder crops with strategic use of high energy supplements, to feeding complete diets under feedlot conditions. The nature of the production system within any area is dictated by climatic and economic factors. Economic return from milk production within a given area is a function of the genetic capacity of the ...
متن کاملFat-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 to Minimize Nitrogen Excretion by Dairy Cows
Dairy cows utilize feed crude protein (CP; N x 6.25) with much greater efficiency than other ruminant livestock but still excrete about 2-3 times more N in manure than in milk. This contributes to increased costs of milk production and to environmental N pollution. The function of dietary CP is to supply the cow with metabolizable protein (MP) as absorbed amino acids (AA) but any extra dietary ...
متن کاملFeeding Lactating Dairy Cows Proteins Resistant to Ruminal Degradation I
Sixty multiprious Holstein cows were fed treatment diets from 11 to 40 d postpartum with corn silage as the forage. Treatment diets each contained a different supplemental protein: 1) solvent soybean meal; 2) extruded soy product; 3) combination of corn gluten meal and distillers dried grains with solubles; and 4) a combination of protein sources from diets 2 and 3. Covariate adjusted means for...
متن کاملFeeding Rumen-Protected Choline to Transition Dairy Cows
Choline [(CH3)3N+CH2CH2OH], also known as trimethyl ethanolamine, is an essential component of mammalian diets as it is required for normal function of cells. It was discovered by Andreas Strecker in 1862, but it remained unrecognized as an essential nutrient for humans until 1998, when dietary reference intakes were established. Choline was initially determined to be essential in the preventio...
