High-protein calf milk replacer capable of enhancing growing performance of calves

Abstract

The invention belongs to the field of livestock raising feeds, and particularly relates to a high-protein calf milk replacer capable of enhancing the growing performance of calves. The high-protein calf milk replacer consists of the following components by weight percent: 3-7 percent of wheat protein powder, 5-10 percent of rice protein powder, 10-30 percent of full-fat soybean powder, 4-10 percent of concentrated whey proteins, 10-30 percent of full milk, 10-25 percent of high-protein whey powder, 8-14 percent of fat powder, 0.05-0.2 percent of a vitamin composite, 1-5 percent of a trace element and mineral composite, 0.2-1 percent of lysine hydrochloride, 0.1-0.5 percent of methionine, 0.1-1 percent of threonine, 0.05-0.3 percent of tryptophan and 0.55-5.0 percent of a microorganism enzyme preparation and acidifying agent composite, wherein the wheat protein powder contains 30-40 percent of glutamine, and the fat powder is prepared from palm oil and coconut oil. According to the high-protein calf milk replacer, the protein content is increased, and the energy absorption rate and the immunity of the calves are improved; the concentrations of vitamins, trace elements and a micro-ecological enzyme preparation are increased; the concentration and the constituent of protease are enhanced; the fat content of the calf milk replacer is increased, the growing speed of the calves is increased, the lean tissues of the calves are increased, settling of body fat is reduced, and the month age of first delivery is shortened.

Description

technical field [0001] The invention belongs to the field of livestock feed, and in particular relates to a high-protein calf milk replacer for enhancing the growth performance of calves. Background technique [0002] The technology of using calf milk replacer and realizing early weaning of calves is one of the technical means used in dairy farming in the world, and is the need of modern dairy production. The existing calf early weaning technology mainly uses calf milk replacer with 22% protein and 12% crude fat as a milk substitute, and its protein source mainly uses soybean protein plant raw materials and dairy products as energy and fat sources. When this kind of calf milk replacer is fed to calves for early weaning instead of cow's milk, the daily gain of calves is 600-700 grams, and the weaning weight at 60 days reaches 80 kg. Reducing the age of mating months and first calving months of back-up dairy cows reduces the lifetime yield of dairy cows, and the fat depositio...

AI Technical Summary

Problems solved by technology

When this kind of calf milk replacer is fed to calves for early weaning instead of cow's milk, the daily gain of calves is 600-700 grams, and the weaning weight at 60 days reaches 80 kg. Reducing the age of mating and first calving of back-up dairy cows reduces the lifetime yield of dairy cows, and the meat quality has higher fat deposition and less protein deposition, which cannot meet people's demand for high-grade meat quality
