Abstract

FIELD: agriculture, poultry feeding. SUBSTANCE: the suggested food mineral additive includes Don limestones, natural bischofite, Elton salt and wheat bran as a filler at the following ratio, weight%: Don limestones 2.0-6.0; bischofite 0.2-0.6; Elton salt 0.2-0.6, wheat bran - the rest.

EFFECT: higher efficiency. 2 tbl

Description

 The invention relates to agriculture, in particular to feeding birds.

 To ensure normal life and high productivity, the bird should receive mineral substances with a diet, which play a crucial role in the metabolism and are the plastic material of the skeleton, as well as the shell of eggs. Among the mineral elements, calcium occupies a special place. A lack of calcium in the diet of birds leads to growth retardation of young animals, a decrease in egg production, as well as a significant departure of the livestock. The main grain components of compound feeds contain a small amount of calcium; therefore, various mineral additives are used, including shell rock and chalk [1]. However, the shell is heterogeneous in composition and contains many whole shells, and is also heavily contaminated with sand. Chalk as a result of hygroscopicity often has high humidity, which has a destructive effect on the details of the feeders.

 Very valuable chemical and physical properties of calcium sources are limestones. They are well eaten by poultry and their use as mineral top dressing increases the productivity of poultry [2].

 A disadvantage of the limestone feed additive is the imbalance of the limestone feed additive with respect to the content of minerals, macro- and microelements necessary for proper nutrition of the bird.

 The technical result is an increase in poultry productivity through the development and use of new, cost-effective feed additives in the diet.

This is achieved through the use of Don limestones, natural bischofite, Elton salt and wheat bran as a filler in the feed additive as a mineral in the following ratio of components, wt.%:
Don Limestone - 2.0-6.0
Bischofite - 0.2-0.6
Elton salt - 0.2-0.6
Wheat Bran - Else
Don limestone [2] contains - minerals in wt.%:
Calcium - 36
Magnesium - 0.11
macro- and microelements in mg / kg:
Manganese - 245
Iron - 835
Zinc - 35
Bischofite contains, g / l:
Magnesium Chloride - 446.25
Magnesium Bromide - 2.96
Calcium Chloride - 0.98
Potassium Chloride - 0.98
Trace elements.

 Elton salt - sodium chloride according to GOST 13830-91.

The technology for preparing a mineral additive is simple and possible in farms of various types, it includes the following operations: grinding and mixing of mineral components using wheat bran as a filler. Filler (wheat bran) is fed to the mixer in an amount of 95% by weight of the additive, mineral additives, 4% of Don limestone, 0.5% of bischofite and 0.5% of Elton salt are fed here, the mixing time is 10-15 minutes in LS- mixers 1 (capacity 20 kg) or SKG (capacity 0.1; 0.2; 0.5; 1.0 m ³ ).

 Feeding experiments on the mineral supplement were carried out on laying hens of the Rodonit cross and broilers of the JSA-15 cross. Feeding of chickens and broiler chickens was carried out according to VNITIP standards with full feed mixtures according to GOST 18221-72 with the addition of the proposed feed additive for 5 laying hens and 1% for broiler chickens. The experiments were carried out at the poultry farms "Kamyshinskaya" and "Volgograd broiler."

 The results of feeding the feed additive on the bird are shown in table 1 and 2.

 Fodder mineral supplementation significantly influenced the egg production of chickens. At the same time, chickens receiving a feed mineral supplement for 4 months of egg laying increased egg production by an average of 9.3 pieces or by 13.4% compared to the base case. There was a tendency to increase the average egg mass by 1.4%. In the hens of the experimental version, the cost of feed for the production of 10 pcs eggs decreased by 11.6%. As a result, from the use of feed mineral fertilizing, net profit increased by 60.27% compared to the base case.

 The use of a feed mineral supplement affected the safety of chickens, increasing the rate by 2.7% and reaching 98.3 in the group, while in the base case it was 95.6%.

 The experimental version showed an increase in live weight of chickens by 9.6%, average daily gain in live weight up to 50.5 g or 13.5%, which gave an overall economic effect higher by 19.5% compared to the base case.
