Dairy cattle concentrate supplement and preparation method thereof

Abstract

The invention relates to a dairy cattle concentrate supplement and a preparation method thereof. The dairy cattle concentrate supplement consists of the following components according to weight percent: 45%-50% of corns, 5%-15% of wheat barns, 5%-10% of soybean meal, 6%-13% of cottonseed meal, 4%-10% of rapeseed meal, 7%-13% of seasame cake, 3%-6% of corn protein powder, 3%-6% of distiller's grain protein feed, 1%-3% of calcium carbonate, 1%-2% of calcium hydrophosphate, 0.3%-1.0% of salt, 0.5%-1.0% of sodium diacetate, 0.4%-2.4% of baking soda, 0.2%-1.2% of magnesium oxide, 0.2%-1.0% of controlled-release non protein nitrogen, 2.0%-4.0% of mineral premixed material and 1.0%-2.0% of composite vitamin premixed material. By applying the dairy cattle concentrate supplement, the nitrogen and phosphorus discharging amount is reduced, the milk yielding amount is increased, and the milk quality is improved.

Description

technical field

[0001] The invention relates to an animal feed, in particular to a dairy cow concentrate supplement and a preparation method thereof. Background technique

[0002] The nutrients needed by dairy cows to maintain life, grow and develop, produce milk and reproduce offspring include water, energy, protein, mineral elements, vitamins, etc. Except for some water, all nutrients required by dairy cows need to be provided through feed. According to the digestive physiology of ruminants, there should be enough cellulose in the diet of dairy cows, and the amount and ratio of neutral detergent fiber and acid detergent fiber should meet the needs of dairy cows to maintain normal digestive function as much as possible. Cellulose is mainly derived from roughage. However, the energy, protein, mineral elements and vitamins of most roughages are relatively low, which cannot meet the needs of growth, milk production and reproduction of dairy cows, especially the milk productio...
