(54) MEDIUM: TO INCREASE EYE-END PEDUCTIVITY IN CHICKENS

one

The invention relates to the field of poultry, in particular to estrogen-induced biostimulants, used to increase meat production in chickens.

Known agents used in feedings of chickens to increase the yield, for example, 3-oxo-17 /% -cyynyl-17-hydroxyextra-4, 9,11-triene are scarce and expensive preparations, and therefore their use in poultry farming is limited to 1.y

The use of synthetic estrogens, such as synstrol, is known to accelerate the onset of puberty and increase chicken production by 7% to 10% .2.

However, synthetic estrogens cause is genetic disorders, carcinogenesis and the demon, the fruit of the offspring, accumulate in the product and eggs of chickens that have been receiving these drugs for a long time, and are not destroyed by heat treatment. May cause. corresponding to 20 meneki in the body of people who ate the m of the eggs and eggs of these chickens. In connection with this, synthetic estrogens are not used in the poultry industry of egg production.

The aim of the invention is to:; search for effective growth stimulators that do not possess toxic properties on the organism of chickens, and especially chickens of scaffolding breeds, and which make it possible to reduce feed costs per unit of production from chickens.

This goal is achieved by using the well-known preparation Panoferol 3, which is a natural mixture of vegetable estrogens secreted from Feruba tenuisecta. In contrast, from the previously known phytoestrogens, panoferol has a very high estrogenic activity, which is not inferior to the activity of synthetic estrogens, is contained in the plant in large quantities (3-4%) and its production is quite cheap (1 kg - 2000 rubles). These properties make it possible (6 difference from previously known phytoestrogens) about the use of panoferol in poultry farming. Unlike synthetic estrogens, panoferol does not have a carcinogenic effect and does not cause genetic disorders, i.e., it is isolated from a grazing plant, to which the animals ’organism is; A1tirovana in the process of evolution. Tests of the biological activity of panoferol in chickens of the ytsenosky breed were carried out in the production conditions of the Tashkent poultry farm. Panoferol was given to chickens mixed with standard feed at the rate of 1 g of the preparation per 1 ton of feed. This mixture was prepared daily and given to the hens in the amount prescribed by the norms of feeding. Dacha drug began with a 100-day age and lasted for the next 100 days to 200 days old chickens. Transfer of pullets to chicken feed produced at the age of 150 days. For comparison, another group of chickens were given osnzstrol (in the same dose, in the same way). Observation of chickens was conducted in te-. 6 months Panoferol had a pronounced zrogogenic effect; increased the size of herders and rpe6euiKOiB, accelerated the onset of egg masonry, increased the average yield by an average compared to the control group (in the equilibrium group treated with synestrol, the average yield increased by less than 1 | degree - by 18.2%). The action of panoferol was accompanied by a decrease in feed consumption for the production of 10 eggs, on average, by 20.3% compared with the control group (under the influence of synzstrol, feed consumption decreased less significantly by 12.5%.

57.0 65.7 64.0 TGr of anxiety The effect of panoferol on the development of the genital organs is reflected in Table. 2, on the biochemical composition of the plant and liver - in Table. 3. The estrogenic effect of panoferol has affected the development of rowing and ovodovodov. The weight of the chickens' group of chickens treated with panoferol was 150.4% of the mass of the chickens of the control group, the mass of scallops - 183.7%. The total protein content, lipids, and glycogen content decreased in the breeder. The estrogenic effect of synestrol was also expressed. The mass of the ytsevodov group of chickens, pr: the best of synestrol, was 159.8%

An average of 22.8% of ipc compared to the control group. The introduction of synestrol, on the contrary, increased the chickens' waste by 25.7%, mainly due to the over-exaggerated breeding farm. Thus, Panoferol surpassed synestrol by increasing its yield and reducing feed consumption for egg production. In addition, panoferol (as opposed to synestrol) contributed to the preservation of hens neszock.

From tab. 1 that panoferol at a dose of 1 mg / kg of feed had a positive effect on the growth rate (%) of pullets. The advantage is especially noticeable in the second month of the cycle, in which pullets receiving panoferol had a 18% higher level of egg laying than in the control group. Over the subsequent months, the intensity of the egg-laying of the pullets of the experimental group did not change significantly compared with the control group. However, over the entire observation period, the difference in favor of the pullets treated with panoferol was 10.3%.

The delivery of synestrol at a dose of 1 mg / kg of feed had a less significant effect on the growth rate. In the second month of laying, its level in pullets treated with synestrol was 8, (5% and for the entire observation period it was 9.4% higher than in the control group.

However, it should be noted that, unlike panoferol, the development of breeders in chickens treated with synzstrol did not fully ensure the process of egg formation, since formed yolks could not be realized by the poultry body to form full-bodied eggs, and the hypertrophy of the breeder in chickens treated with synestrol, unlike panoferol, caused it to fall out in some chickens. and.

The effect of panoferol on feed costs is shown in Table 4. It is clear from it that the group receiving panoferol is much more economical than the control payment for the product. Feed costs for 10 eggs in this group were on
