Using Fish Meal in Dairy Rations
: ed u/c ata log Bypass protein is an important part of the diet of lactating cattle. The National Research Council recommends that bypass protein make up 34 to 36 percent of the total crude protein consumed by lactating cattle. Fish meal is high in crude protein (65 to 70 percent) and is a source of bypass protein (also called ruminally undegradable protein or RUP). It can be used in dairy rat...
متن کاملIonophores in Dairy Rations
Introduction Ionophores have been used extensively in the beef industry in Canada since 1977. Until recently, there has been no label indication for use of ionophores in lactating dairy cattle. Ionophores are feed additives that alter rumen microbial populations through ion transfer across cell membranes. In Canada, the label warning prohibiting the use of Rumensin premix in lactating dairy ca...
متن کاملUsing Distillers Grains in Dairy Cattle Rations
Distillers grains are co-products produced from the fermentation of grains for alcohol. Traditionally, alcohol was produced mainly for the beverage liquor industry, but in the last 20 years its use as an alternative fuel has increased significantly. This increased demand has led to the development of several ethanol production plants in Minnesota and the surrounding area. In 1996, it is estimat...
متن کاملOptimizing Starch Concentrations in Dairy Rations
Currently, many nutritionists consider only the total nonfiber carbohydrate (NFC) fraction when formulating rations for lactating dairy cows. Increasingly, we need to measure the components that comprise NFC (starch, sugars, soluble fiber, and β-glucans) and formulate rations that optimize the concentration of each component in the diet. Starch is the major NFC fraction in dairy cattle diets, a...
متن کاملUse of Glycerol in Dairy Rations
Increased cost of common feedstuffs and increased availability of coproducts from plant-based biofuel manufacturing has enhanced interest in the use of these coproducts in rations for dairy cattle (Donkin and Doane, 2007). Glycerol (commonly marketed as crude glycerine with a glycerol content of approximately 80%) is a coproduct produced during biodiesel production from soybean oil and is becom...
