SU1535515A1 - Method of preparing feed additive for young cattle - Google Patents

Abstract

FIELD: feed production. The aim of the invention is to increase the nutritional value of the feed additive and simplify the process of its preparation. The method of preparation of the feed additive for young cattle involves mixing skimmed milk powder with a vegetable component, which is used as rapeseed, and mixed in a ratio, wt.%: Skimmed milk powder 30-50, rapeseed 50-70. Then the mixture obtained is extruded and crushed to a particle size of 0.22-2.0 mm. 1 kg of feed additive contained 243 - 312 g of protein, 310 - 380 g of fat, 8 - 9% moisture, 235 - 480 mg of vitamin E (feed. Units 1.31 - 1.52). When feeding the bodies of the feed additive obtained by the proposed method, the average daily increase was 911 g per 1 head. 1 tab.

Description

FIELD: feed production.

The aim of the invention is to increase the nutritional value of the resulting feed additive and simplify the process of its preparation.

Example. Feed supplements were prepared for calves up to 3 months old.

For the preparation of a koom supplement, Hannah seeds of a non-erucaceous rapeseed variety were thoroughly mixed with skimmed milk powder. Then, the obtained dry feed mixture was extruded on a PEC-125x8 npecce extruder.

After extrusion, the finished product was crushed to a fines size of 0.22–2 mm, then cooled for H8 h (10–2 ° C), the color of the product from green to dark green with white spots, liver smell, sweet taste .

To obtain a high quality feed additive for calves, skimmed milk powder and rapeseed need to be used without moisturizing it.

1 kg of feed additive contained 2–3–312 g of crude protein, 310–380 g of fat, 8–9% moisture, 1.31– 1.52 feed units, mg of vitamin E,

which has antioxidant properties.

Natural antioxidant in the form of vitamin E protects the finished product from damage. Therefore, it is not necessary to add factory antioxidants (santoquin, diludin) to the feed additive, in addition, the additive contained 0.01 + 6-0.08 mg% of vitamin C -8 mg of vitamin A. Vitamins are contained in quantities sufficient for meet the needs of the body of the calf.

The feed additive did not contain erucic acid, glucosinolate, nitrates, nitrites, mercury and phosphorus-organic compounds, DDT, alkaloids and glucosides.

The nutritional value of 1 kg of rapeseed is high - 2.20-2.3 feed units, and skimmed milk powder - 1.20 feeds per unit. (nutritional value of the additive according to the prototype - 1.26 feed units). The production process of the feed additive according to the proposed method is simplified by the selection of non-deficient feed components.

The chemical composition and nutritional value of the resulting feed additive are given in the table.

Feed additive in a mixture with concentrated feed.

Included it in concentrates and in the period of accustoming the bodies to them. From 30 days

In this age, the supplement was fed twice a day at a rate of 0.1-0 kg per head. The maximum rate of feeding - 0.4 kg / head / day, and the minimum - 0.1 kg.

i

Tel ta grew well and developed.

The average daily increase in the calves of the control group (without adding the proposed additive to the composition of the concentrates in the diet) was 827 g, and the experimental group was 911 g per 1 head.
