Feed for beef cattle and preparation method thereof

Abstract

The invention discloses feed for beef cattle.The feed is prepared from, by weight, 40-50 parts of silage corn, 5-15 parts of mulberry branch powder, 5-10 parts of alfalfa, 1-6 parts of oat grass, 4-10 parts of soybean meal, 5-15 parts of distillers' grains, 5-10 parts of corn flour, 1-5 parts of wheat bran, 10-20 parts of rice bran, 10-15 parts of shrimp shell meal, 5-10 parts of fishbone powder, 4-10 parts of locust tree flowers, 5-10 parts of herba taraxaci, 1-2 parts of calcium hydrophosphate, 0.5-1.0 part of sodium bicarbonate, 0.2-0.5 part of slat, 0.5-1.0 part of tea polyphenol and 0.05-0.2 part of tea saponin.According to the feed, the pH value and NH3-H concentration of the beef cattle rumen can be significantly decreased, the microbial protein yield of the beef cattle rumen is increased, the protozoon quantity of the beef cattle rumen can be significantly inhibited, and the protein content of beef can be significantly increased.

Description

technical field [0001] The invention belongs to the field of livestock feed, in particular to a feed for beef cattle and a preparation method thereof. Background technique [0002] Rumination refers to returning half-digested food in the stomach to the mouth for chewing again after a period of eating. Ruminants are animals that ruminate, usually herbivores, because plant fiber is difficult to digest. Ruminants generally eat in a hurry, especially roughage, most of which are swallowed into the rumen without being fully chewed. After being soaked and softened in the rumen for a period of time, the food is regurgitated and returned to the mouth. Swallowed into the rumen. [0003] There is a kind of rumen protozoa in the rumen of ruminants. The nitrogen source of the protozoa mainly comes from various bacteria. The reduction of the number of protozoa can increase the number of bacteria by 3 times. It helps the fermentation of the substrate in the rumen fluid, and at the same ...

AI Technical Summary

Problems solved by technology

[0004] The food eaten by ruminants first enters the rumen through the oral cavity and esophagus. Bacteria, protozoa and fungi in the rumen decompose and ferment 60%-70% of the protein, amino acid, starch and fat in the food, part of which is absorbed by microorganisms and part of which is produced during fermentation Methane, ammonia nitrogen and other substances not only cause feed energy loss but also cause environmental pollution
