SU1530162A1 - Method of producing feed additive for the ruminants - Google Patents

Abstract

This invention relates to fodder production, in particular, to a technology for producing feed additives from low-value plant raw materials for ruminants. The purpose of the invention is to increase the digestibility of the feed additive. The straw chopping is mixed with liquid bird droppings, providing a dry straw: dry droppings ratio of 10: 1 to 1: 1, the moisture content of the mixture is adjusted to 40-60%, and the hydrobaro-thermal treatment of the mixture is carried out. The best results in convertibility (58%) were obtained with a straw: litter ratio of 4.85: 1 and a mixture moisture content of 52%. The granules obtained by this method contained 93.4% of dry matter, crude protein 8.6% fiber 45.8%, in 1 kg - 0.53 k.e. The resulting product is well eaten by animals.

Description

The invention relates to fodder production, in particular, to the technology of obtaining feed additives from low-value vegetable raw materials for ruminants.

The purpose of the invention is to increase the digestibility of the feed additive.

Example 1. In the laboratory, 11 variants of the proposed method were tested. Straw (wheat) chop was mixed with chicken droppings. The humidity of the straw varied from 7 to 30%, the humidity of the litter varied from 40 to 80%. After mixing the components, the mixture was loaded into a laboratory autoclave and subjected to hydrobaro-thermal treatment. The composition of the mixture, its processing conditions are presented in Table. 1, the quality of the resulting feed additive in the table. 2

In all variants, except for 1 and 7, the portability of the obtained additive was higher (39 58%) than the digestibility of the straw treated by a known method (35%).

PRI mme R 2. Mixed 8570 kg of rye straw with a moisture content of 30% (dry straw 5999 kg) with 65 gO kg of bird droppings with a dry matter content of 19% (dry manure 1237 kg), obtaining the ratio of dry straw: dry manure 4, 85: 1. The moisture content of the mixture is 52%. The containers with the mixture obtained were loaded into a horizontal autoclave. After steaming at a pressure of 6-7 atm (temperature 160-170 ° C) for 90 minutes and depressurizing the mixture.

Claims (1)

The dry matter content in granules is 93.4%, crude protein is 8.6%, fiber content is 45.8%, and in vitro digestibility is 58%. In 1 kg of pellets contained 0.53 k.e. Invention Formula The method of obtaining a feed additive for ruminants, including Lazhneniye and hydrobarotermic treatment of straw, characterized in that, in order to increase the digestibility of the feed additive, before hydrobarothermal treatment, straw is additionally mixed with liquid manure of birds in an amount that provides a mass ratio of dry straw: dry manure (10: 1) - ( 1: 1), the moisture content of the mixture being adjusted to 40-60%.
