Formula and production process of dairy cow protein particle feed

Abstract

The invention relates to a formula of dairy cow protein particle feed which comprises the following components by weigh percent: 15-40 percent of energy feed, 40-80 percent of protein feed, 0-9 percent of oil and fat, 0-18 percent of amino acid, 0-2.3 percent of vitamin, 1.6-2 percent of calcium carbonate, 0-1 percent of adhesive, 0-0.1 percent of antioxidant and 0-0.3 percent of antimold agent. The production process of the dairy cow protein particle feed comprises the following steps: a, weighting the components according to the weight percent thereof; b, grinding the components; c, mixing the ground components; d, tempering the mixture; e, granulating the mixture; f, post-curing the granules; g, drying the granules; and h making the granules into the dairy cow protein particle feed which has the diameter of less than 4 mm and the length of 1 to 2 times of the diameter and contains the dry matter of more than 88 percent. The dry matter contains the crude protein of more than 20 percent and the crude fiber of less than 18 percent. The dairy cow protein particle feed can be kept stable in water for more than 5 min and has the dispersion rate of less than 12 percent in water. The protein in the dairy cow protein particle feed is less degraded by the rumen microorganisms, the rumen bypass efficiency of the protein is improved, the need of the essential amino acids in the nutrient of protein in the dairy cow body is balanced, the efficiency of using the dairy cow protein particle feed by the dairy cow is increased, the health status of the dairy cow body is improved and the pollution of the nitrogen in the excrement of the dairy cow to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of protein feed for dairy cows, and more specifically relates to a formula of protein pellet feed for dairy cows and a production process thereof. Background technique [0002] Protein feed (referring to feed with a crude fiber content of less than 18% in dry matter and a crude protein content equal to or higher than 20%) is the main nutrient as protein. For animals, the essence of protein nutrition is amino acid nutrition. Animals After ingesting protein feed, through the action of digestive enzymes in the gastrointestinal tract in the body, the protein is degraded into amino acids or small peptides, which are absorbed and utilized to play a nutritional role. However, dairy cows are ruminants and have a rumen with complex functions. The complex microbial populations in the rumen have a strong degradative effect on the protein feed they eat and become amino acids. Some amino acids are used to synthesize micr...
