Feed additive and preparation method and using method thereof

Abstract

The invention discloses a method for preparing a feed additive by using grape residue as a main raw material, which comprises the following steps: 1) air-drying or oven-drying the grape residue; 2) crushing, namely mixing the grape residue, brain, methionine and sodium selenite according to a weight percentage ratio of 56.35 percent: 42.25 percent: 0.70 percent: 0.70 percent, crushing and uniformly mixing; and 3) cooling the crushed powder, bagging and sealing. In the invention, the formula is reasonable, the cost is low, tannin from grape seeds in the grape residue is used as a protector forrumen bypass protein in ruminants to improve the feed nutrient digestion and nitrogen utilization of the ruminants, and when taking the feed with the additive, the ruminants can gain weight and high apparent digestibility of proteins.

Description

technical field [0001] The invention provides a feed additive for ruminants, a preparation method and a use method thereof, and belongs to the technical field of feed additives. Background technique [0002] At present, commercially available feed additives are mainly aimed at increasing vitamins, minerals (or trace elements), antibiotics and chemical drugs, and are added to feed to prevent livestock and poultry vitamin and mineral deficiency and animal diseases; It is a hormone, although it can also promote the growth of livestock and poultry, but meat contains more hormones, which has certain side effects on the human body, especially children, and brings harm to the health of human beings who consume animal products. This is extremely inconsistent with the world consumption trend of adding and applying medicines that are pollution-free, low-residue, green and environmentally friendly, and nutrition and disease-resistant substances are integrated.
