Abstract

The invention relates to agriculture, in particular to methods for feeding poultry. A method for feeding poultry includes feeding compound feed with a feed additive, which is a mixture of gum with dimethyl sulfoxide, gum 40-50% by weight, dimethyl sulfoxide is the rest. The additive is introduced into the feed in an amount of 0.005-0.015 May. %, chickens there in meat breeds for 2 days. aged 20-22 days. and for 3 days at the age of 35-37 days, and young hunting species for 3 days. aged 37-39 days and for 4 days. aged 56-58 days 2 tab.

Description

The invention relates to agriculture.

The purpose of the invention is to increase the gain in live weight and safety of poultry, reducing the consumption of additives.

Example 1. Chicken ta broilers cross-country Change at the age of 1 day were divided into 10 experimental groups of 57 goals in the group. Each group was placed in three cells of the cell battery KBU-3 with 19 goals. Chickens of all groups received mixed feeds of the same composition, the nutritional value of which corresponds to the established norms of feeding. The first group of chickens (control) received mixed feed supplemented with 1k phenosan (J5 - (3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid) from 28 to 56 days of age. Chicken from the 2nd to 7th groups from the 35th to the 37th day of cultivation received mixed feed containing 0.003-0.20 wt.% A mixture of gum and dimethyl sulfoxide (DMSO) additives, in which gum was taken in an amount of 35-55 wt.% And DMSO rest. Chicken of the 8-10th group received mixed feed containing 0.015 wt.% Of the proposed additive in the ratio of components, wt.%: Gum - 50, DMSO - the rest. In this case, the chickens there of the eighth group were fed the additive on the 5-6th day, 20-21 days and from the 35th to the 37th day of rearing, the chickens there in the ninth group were fed the additive on the 20th-21st day and from the 35th to the 37th day of rearing, and the chickens there, in the tenth group, supplements were fed at the age of 21 to 49 days.

The circuit and test results are presented in table 1.

Application of the proposed method for feeding t-broiler chickens with the inclusion of 0.005-0.015 may in feed. % of the additive consisting of gum and DMSO in the ratio, wt.%: gum 40-50. DMSO - the rest, provides an increase in the increase in live weight of broilers by 8.3-16.7% and the safety of the livestock by 3.5% compared with the control. Thus, the feed additive used in the proposed method has a significantly greater growth-promoting activity compared to the prototype.

The greatest growth-promoting effect is exerted by feeding chickens to compound feed broilers with the addition of gum and DM CO for 2 days from 20 days of age and for 3 days from 35 days of age. Introduction to the feed of the proposed supplement at an earlier age and for a longer time provides a lower growth-promoting effect or its absence.

Example 2. Hunting chickens at the age of 36 days were divided into 2 groups of 140 animals each. Content is outdoor. The first group of chickens (control) received complete feed recommended by the Central Scientific Research Laboratory of Glavokhot of the RSFSR, which was introduced at the age from 37 to 60 days. the addition of phenosan 1k in an amount of 0.012% by weight of feed.

The chickens of the second group were introduced into the main diet of the proposed additive in an amount of 0.015 wt.%, Containing gum - 50 wt.% And DMSO - the rest. The supplement was administered within 3 days from 37 days of age and within 4 days from 56 days of age. At the age of 65 days young to the pheasant sold and released into the hunting ground.

The results are presented in table. 2.

Feeding young pheasant of hunting feed with the addition of gum and DMSO allows to increase the gain in live weight by 28.4% and the safety of the livestock by 10.8% compared to the use of feed with the addition of 1 k phenosan.

The proposed method for feeding poultry can be implemented with any method of growing meat breeds of agricultural poultry and young hunting birds.

Using the proposed method of feeding poultry provides, in comparison with known methods, the following advantages:

the introduction of a complex additive in the feed significantly increases the increase in live weight and the safety of livestock;

the high growth-promoting activity of the proposed additive allows to reduce its consumption by optimizing the frequency and duration of feeding of feeds enriched with the above additive.

SUMMARY OF THE INVENTION A method of feeding poultry, comprising feeding compound feed with a feed additive, characterized in that, in order to increase the gain in live weight, preserve the bird, and reduce the consumption of the additive, a mixture of gum with dimethyl sulfoxide is used as a feed additive in the following ratio, wt.% :. Zhivitsa40-50 Dimethyl sulfoxide at the same time, the additive is introduced into the feed in the amount of 0.005-0.015 wt.% chicken of meat breeds for two days at the age of 20-22 days and for three days at the age of 35-37 days, and young hunting species for three days at the age of 37-39 days, and for four days at the age of 56-58 days.
