Abstract

Usage: in feed production. SUMMARY OF THE INVENTION: A method for producing a whole milk substitute for calves involves preparing a protein base from skim milk (or skim milk and buttermilk, or whey), a fat emulsion, and adding phosphatide concentrate, dry fodder lysine, grizin, vitamins, macro and micronutrients. The fat emulsion is made from rapeseed oil and animal fat, taken in a ratio of 0.4-4: 1.5 table.

Description

FIELD: feed production.

The purpose of the invention is to increase the biological value and digestibility of the whole milk replacer.

PRI me R 1. To prepare a protein base, skimmed milk (or skimmed milk with added buttermilk or whey) is pasteurized at a temperature of 78-80 ° C on a vacuum evaporator and concentrated to a mass fraction of dry matter of 35%. At the same time, a fat emulsion is prepared. For this, 47.2 kg of rapeseed oil and 117.8 kg of animal fat (0.4: 1 ratio), phosphatide concentrate, and fat-soluble vitamins A and D according to option 1 ( 1) to 250 kg of a condensed protein base, mix thoroughly and emulsify with a homogenizer at a pressure of 8-10 MPa for 10-12 minutes. Then, the remaining portion of the condensed protein base, lysine, grisin,

vitamin bi2. salts of macro and micronutrients and again thoroughly mixed.

The resulting feed contains 1 kg of 40% dry matter and 8% fat. The energy nutritional value of 1 kg of milk replacer is 2 feeds. units

EXAMPLE 2 The process for the preparation of a milk replacer is carried out analogously to example 1. But the protein base is prepared from skimmed milk and whey according to option 2 (Table 1). Whey is pre-blended to 20 ° T and the protein base is concentrated to a dry weight content of 45%.

To prepare a fat emulsion, 85.0 kg of rapeseed oil and 85.0 kg of animal fat (1: 1 ratio) are used, a dry feed lysine preparation is added and the whole mixture is dried on a spray dryer to a moisture content of 5%. The resulting feed contains 1 kg of 95% dry matter and

17% fat. The nutritional value of 1 kg of milk replacer is 2 feeds. units

Example 3. The technological process of the preparation of milk replacer is carried out analogously to example 1. But the protein base is prepared from skimmed milk, buttermilk and whey according to option 3 (Table 1). The protein base is not subjected to thickening, but a protein-fat mixture is immediately prepared, adding bone fat, fat-soluble vitamins A and D, vitamin Bi2, lysine, grisin, salts of macro- and microelements. 138.4 kg of rapeseed oil and 34.6 kg of bone fat (in a 4: 1 ratio) are used to prepare the fat emulsion. After thorough mixing, the mixture is warmed to a temperature of 50 ° C, emulsified on a rotary disperser for 30 JWH, pasteurized and cooled to 8 ° C.

The resulting feed product contains in 1 kg 10% dry matter and 2% fat. The nutritional value of 1 kg of the milk replacer is 0.2 feed. units The addition of rapeseed oil in the ratio of 0.4–4: 1 to animal fats in the replaceable milk replacer improves the biological value of the feed, the digestibility of crude protein and the uptake of nitrogen, as evidenced by the data in Tables 2, 3 and 4.

Feeding the milk replacer there 1.5-2 months old, 6 kg per head per day, had a positive effect on their health and contributed to an increase in the average daily amount.

growth of live weight, as evidenced by the data table. five.

The highest average daily gain in live weight for the 62 days of the experiment was observed in the groups of bodies that received WMS with a ratio of rapeseed oil to animal fats ranging from 0.4 to 4: 1, which is 8–15% higher than in the group that received Milk replacer without rapeseed oil (prototype). The increase in body weight gain is due to the greater intake of unsaturated fatty acids, essential amino acids into the body, and better digestibility and digestibility of crude protein.

The introduction of rapeseed oil into the milk replacer allows reducing the use of phosphatide concentrate and antioxidants, which helps reduce the cost of feed.
