Abstract

Use of t-broilers in chicken feed The essence of t-broiler chicken feed as a herbal supplement containing carotene, use marie white flour from the calculation of 2 - 5% in the first period of cultivation and 3 - 10% in the second, which helps to reduce the consumption of vitamin A by 1/2 the recommended norm

Description

The invention relates to agriculture, in particular to fodder food, and can be used in feeding t-broiler chickens.

A known method of growing t-broiler chickens is to increase the average daily gain in live weight and reduce feed consumption by 1 kg of growth, including the introduction of 3% sorbose mother liquor into the standard feed for t-broiler chickens - waste from the processing of seaweed kelp for mannitol and sodium alginite.

The disadvantage of this method of growing t-broiler chickens is to obtain a relatively low live weight of chickens with a longer sprouting period and high feed costs per 1 kg of growth.

The closest technical solution to the proposed one, chosen as a prototype, is a method for growing t-broiler chickens, which includes introducing pea grass meal into the feed composition. An increase in the share of this feed in the diet reduced live weight and increased cost; feed per unit of increase / live weight. At the same time, this resulted in a small amount of corn grain, meal and yeast, and increased concentration of vitamin A and carotene in blood serum and observed ; 1 p., And / and more and "lo-m-i in the liver AND TuChlchb. -TT

The disadvantage of this method of growing whole g-boilers is the lower provision of gtps with carotene. Use of dried H, goat and broiler when growing in small quantities / increments of ch. Chickens with gross feed costs.).

Yael isooor; t ni - increase in live weight gain of chickens t while reducing feed costs per unit of output.

The set value is achieved by the fact that in the well-known method of growing ippp broilers, as well as a herbal supplement containing carotene, white marie flour is used at a rate of 2-5% in the first growing period and 3 10% per hour, chgo helps to reduce the consumption of vitamin A nn 1/2 of the recommended norm.

Grasses for white marie flour The new fodder composition of plants of natural flora in fodder production The chemical and amino acid composition of grass flour, white and pea flour is presented in Tables 1 and 2.

The data in Tables 1 and 2 show, h; the quality of the Mari white herb flour is significantly superior to the pea grass meal.

The use of mariba grass meal in feeds for broiler chickens as carotene-rich feed is not known from information sources.

Indicated amount of grass meal

marie white is enough to achieve the goal. The inclusion of 2% grass marie white flour corresponds to the recommended norms for feeding poultry. Introduction to feed of less than 2% of grass meal excludes

an opportunity to give an informative answer about the use of mari white herb meal in feeding oroilers. When using more than 10%, the level of fiber in animal feed rises, which is undesirable

Example. The experiment was carried out on white plymutrok chickens of the Sz x C / 1 line from daily chickens with an average live weight of 40 i according to the analogue principle

(breed, live weight, age) 6 groups of chickens were formed. Feeding of chickens was carried out by a dry balanced feed mixture according to the scheme presented and t bl3

 The first group (the chickens robo group received standard compound feed with the recommended level of grass meal for the periods of pirzhtsivpny Second group main ration (RR) with g and 10% grass

mari yeloya flour according to chyrashshkshi periods

 ontrol groups of chickens g received all vitamins according to the recommended standards Hipl 1am test groups of skarmlino, basically a diet corresponding to the smokestack group 2 different composition and doses of thiamines So, group 3 pigs against the background of the main diet received 0.5 norms of vitamin A and all other vitamins by

Group 4 chickens there added all the vitamins to the diet except for vitamin A. Group 5 received 0 5 vitamin A norms and, according to the norms, Dz vitamins. E and 612, a group of 6 vitamins Dz, E and Bi2.

Composition and nutrition of feed

are given in table 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 in the feed of tray mari white flour or 2 to 5% in the first growing period and from 3 to 10% in the second did not negatively affect the zootechnical indices and broiler brooding.

Against the background of an increase in the composition of the compound feed of the level of white marie flour to 5-10%, respectively, to the growing periods, a dose of vitamin A may be reduced by half the recommended norm (group 3). The live weight of group 3 chickens was higher than in the control groups, although the difference was not significant. In this group, a decrease in feed costs per 1 kg of increase in live weight by 8.81% compared with the standard, and compared with the control groups 1 and 2, respectively, by 4.17 and 4.61%.

The live weight and average daily gain of chickens of groups 4.5 and 6 were approximately at the same level, but remained above the Pticeprom standard (VNITIP).

The use of Mary White grass flour contributed to an increase in the content of carotene in the liver and blood serum, vitamin A in the blood serum of chickens by

compared with control groups, regardless of the level and set of vitamins introduced into the compound feed (Table 6).

Using the proposed method for growing t-broiler chickens as compared with the prototype, it is possible to obtain higher live weight gain while shortening the growing time, reducing feed costs by 1 kg of live weight gain and saving vitamins introduced into the feed.
