with

The invention relates to feed production and can be used in feeding t-broiler chickens.

A feed is known that contributes to an increase in the average daily gain in live weight and a decrease in feed consumption per 1 kg of gain, including the introduction of 3% t-broiler chickens into the composition of a standard compound feed - sorbose mother liquor - waste from the processing of laminaria seaweed into mannitol and sodium alginite.

The disadvantage of this food is the production of a relatively low live weight of chickens with a longer growing period and high feed costs per T kg of growth. -.

The closest technical solution selected as a prototype is a feed comprising pea-oat grass meal. Increase in the share of this

feed in diets reduced live weight of chickens, increased feed costs per unit of increase in live weight. At the same time, corn, meal and yeast grains were saved, the concentration of vitamin A and carotene in the blood serum increased, and their greater deposition in the liver and carcass of chickens was observed.

A disadvantage of the known food is a lower content of carotene in it, and the use of the known food results in smaller gains in the mass of chickens at high feed costs.

The purpose of the invention is to increase the gain in live weight of chickens while reducing feed costs per unit of production and improving the supply of poultry with carotene and vitamin A. The use of grass marie white flour (Chenopodlum album) in feeding birds

helps to expand the range of feed.

This is achieved by the fact that in the well-known chickens for t-broiler chickens, herbal marie flour is added at a rate of 2 to 15% in the first growing period and from 3 to 20% in the second m. 7 ::; y / z-addy:; . . ;:

Grasses on white is a new ragsteni feed for natural flora in feed production. The productivity and quality of the mari white and pea-oat grass meal are presented in Table. 1.

The data in the table show that the yield and quality of the marina white grass meal are significantly superior to pea flour.

The use of mari white grass meal in compound feeds for broiler chickens is not known from information sources .; . ;

; The amount of mari white herb flour is sufficient to achieve the goal. The inclusion of 2% herbal mari white flour corresponds to the recommended norms for feeding poultry. Introducing less than 2% of grass meal into compound feeds does not make it possible to answer the question under study on the use of marie white flour. feeding broilers. When using more than 20%, the level of fiber-in compound feeds increases, which is undesirable.

P r and m r. The experiment was carried out on chickens tach-broilers of the breed white plymouthrock of Cz x C4 lines. From daily chickens, on the basis of analogues (age, live weight, breed), 6 groups of 93 heads each were formed. Dry bulk feed was fed to the chickens according to the scheme given in table 2, - С:.

The control group of chickens received standard compound feed with the recommended level of grass meal for growing periods. In the 2 experimental group of pea oats -

Productivity and quality of grass flour of mari white and pea-oat (average data for 1987-1987)

on herbs to flour replaced The same amount of mari white herb flour.

In subsequent experimental groups, the content of grass meal was increased due to a decrease in corn grain and soybean meal. The composition and nutritional value of compound feeds are given in Tables 3 and 4. According to the content of the main nutrients, the feed of all groups was balanced and corresponded to the recommended norms.

The results of the experiment (Table 5) showed that the presence of Mari white herb flour in mixed feeds from 2 to 5% in the first growing period and from 3 to 10% in the second did not negatively affect the safety and growth of t-broiler chickens . The live weight of the bird at 7 weeks of age was approximately the same in the 2,3,4 groups compared to the control group (the difference was not significant, but remained above the Pticeprom standard (VNITIP).

Feed costs per unit of production in the 2,3,4 groups were lower than the control by 5.19, 0.04.1.42%, respectively. ;

The use of Mari white herb flour had a positive effect on the supply of vitamin A, carotene to the poultry, and was directly dependent on the level of this feed (Table 6).

The use of pre-cooked feed for t-broiler chickens compared with the prototype allows to obtain higher gains in live weight, while reducing the growing time and reducing feed costs per 1 kg of live weight gain.
