Abstract

The invention relates to feed production. The proposed method for growing broiler birds includes the addition of a biologically active protein biosynthetic supplement to the main diet in the form of carnitine, which is introduced into the feed in an amount of 200-500 mg per 1 kg of feed. The resulting mixture is fed daily from daily to 70 days of age. The method allows to reduce by 11-18% the cost of feed per unit of increase in live weight, increase the safety of young animals to 100% and improve the meat quality of poultry meat. 2 tab.

Description

The invention relates to feed production.

The aim of the invention is to increase the live weight of the bird, its safety and reduce feed consumption.

For example, the Daily young (chickens, turkey poults, guinea fowl) are placed in one Russian battery type R-15 up to 70 days of age. For tsesar t-broilers that are not widely grown in poultry farms, VNITIP has developed a planting density, front watering and feeding, light, temperature and humidity conditions. Carnitine is added to the feed immediately before feeding in the prescribed amounts at the rate of 200-500 mg per 1 kg of feed, and the resulting mixture is fed daily from daily to 70 days of age. Carnitine (DL-4-trimethyl-amino-3-oil per acid) refers to non-hormonal anabolic agents.

It is a homogeneous crystalline powder of white color, odorless, readily soluble in water. The preparation is stable; it does not cake during storage. Carnitine stimulates the digestive glands, increases the digestibility of feed nutrients, and stimulates protein biosynthesis. The introduction of carnitine into the main diet helps increase the mobility of the bird and the development of pectoral and leg muscles in it. Studies have shown that carnitine stimulates the formation of protein in all tissues, starting from the first week of feeding with carnitine supplementation.

The results of the study are shown in Tables 1 and 2.

As studies have shown, all doses of carnitine stimulated the growth of Caesar t-broilers and increased their live weight by 13-24% at 42 days of age and by 12-22%

at 70 days of age. The safety of livestock is 100%.

The reduction in feed costs was 11-18%. Carnitine supplements in the diet of Caesar broilers increased energy expenditures for the implementation of anabolic processes occurring in the body, which contributed to the improvement of meat quality.

In Table 2, it can be seen that the live weight of Caesar t-broilers increases, and feed consumption decreases with the introduction of carnitins.

From table 1 it is seen that the ratio of muscle mass to bone mass during feeding poultry supplemented with carnitine increases.

In general, the mass of semi-gutted carcass increases by 15-23%, edible parts - by 23-34.6%, hard muscles - by 20-41%, foot muscles - 25.7-45.7%;

It is most economical to use 200 mg of carnitine per 1 kg of feed, as there is an effect on all parameters with a small amount of carnitine use. . ..
