[0033] Influence of the milk substitute of example 1 different crude protein levels on the growth and development of calves

[0034] In 2006, a feeding experiment of milk substitutes with different levels of crude protein was carried out in Beijing Daxing Dairy Farm. The newborn calves were divided into 3 groups and fed three milk replacers with crude protein content of 18%, 22% and 26% respectively. The test lasted for 60 days. The results showed that the calves were fed with the milk replacer with 22% crude protein content Key indicators such as live body weight gain, body height and chest circumference of the calves were higher than those of the other two groups of calves. The test data are shown in Table 1.

[0036] Example 2 Effects of different crude protein levels of milk substitutes on calf protein digestibility in vivo

[0037] The calves were fed with three kinds of milk substitutes with crude protein content of 18%, 22% and 26%, respectively, and the digestion and metabolism tests were carried out at the age of 12-20 days, 32-40 days and 50-60 days, respectively. The test results show that the calf eats milk replacer with a crude protein content of 22%, and the crude protein digestibility reaches 76.34%, 76.17%, and 75.36% at the age of 12-20 days, 32-40 days, and 50-60 days, respectively. Both were better than calves fed milk replacer with 18% and 26% crude protein, see Table 2.

[0039] Example 3 Validation of two-stage milk replacer feeding effects for calves

[0040] In 2006, a comparative test of two kinds of milk substitutes was carried out in a dairy farm in Tongzhou District, Beijing. The calf of the control group was fed with the patented milk replacer of ZL 02128844.5, and one product was used throughout the period; Phase milk replacer products, the test was carried out for 60 days. Mainly measure the change of the calf's body weight and bust, the results show that using stage calf milk replacer, the calf is all higher than the control group in weight gain and body size (chest girth), see Table 3, Table 4.

Abstract

A two-phase milk substitute instead of foremilk and milk for calf is prepared from the vegetative protein (soybean protein), whey powder, water-soluble fat, digestion assistant, minerals and vitamins.

Description

[technical field] [0001] The invention relates to a method for producing two-stage milk substitutes for calves (early milk substitutes and late milk substitutes) with active ingredients such as plant protein, milk products, water-soluble fat and enzyme preparations, belonging to animal nutrition and feed science of animal husbandry field. The invention also relates to the types and specifications of the raw materials required for the production of the calf two-stage milk substitute, the nutritional composition of the milk substitute, and the technology and method for feeding the calf. [Background technique] [0002] 1. The use of calf milk replacer and early weaning are innovations in calf breeding [0003] With the improvement of people's economic income and food consumption level, my country's dairy farming industry is showing a trend of great development. By the end of 2006, the number of dairy cows has exceeded 15 million, and the number is still increasing. Calves ar...
