Description

The invention relates to agriculture, in particular to poultry farming, and can be used in the cultivation of broiler chickens both in poultry farms, and in private or farms.

Known methods for growing broilers, in which iron-based multicomponent feed additives are introduced into the main diet in the form of a mixture of water-insoluble powders made of iron, copper, zinc, and others. in an amount of from 0.01 g to 0.1 g per head per day daily or as a mixture of succinic acid salts of iron, copper, zinc, manganese and cobalt succinates in an amount of from 0.001 g to 0.01 g per head 1 time per 3 days (see RF patent No. 2086148, A 23 K 1/16. Publish. 08/10/97. Bull. No. 22; RF patent No. 2092074, A 23 K 1/16, Pub. 10.10.97. Bull. No. 28 )

With good results of the use of such additives in experiments, some disadvantages of their use include the fact that these iron-containing multicomponent compositions are not commercially available, and small doses of the introduction of such powders complicate the technology of feeding and mixing them with the feed of the main diet.

There is also known a method of feeding farm animals and poultry, in which iron ascorbate with a vitamin C content of not less than 8% in terms of ascorbic acid, not less than 3% in terms of iron, is introduced into the diets as a growth-promoting and biogenic preparation, where as a filler use bran at a dose of 0.6-5.0 kg per 1000 kg of feed, which according to the authors provides a significant increase in live weight of the bird (up to 5.1%), the safety of the livestock and improving the quality of meat (see RF patent No. 2095995, A 23 K 1/16. Publish. 20.11.97. Bull. No. 32).

With ease of use and good results of use, the disadvantages of the method include the fact that iron ascorbate of such a composition on bran is not produced by industry, and the bran present in the preparation also changes the composition of the diet from standard compound feed and requires its correction, while the content in the addition of an iron preparation within 3% for broilers is relatively low, which may require the introduction of other additional preparations of this element, complicating and increasing the cost of broiler growing.

The objective of the invention is the search for means of increasing the productivity of broiler chickens in the form of a mass-produced inexpensive and easy to use iron-containing preparation approved for use in agriculture, which allows to obtain an increase in live weight of broilers during fattening while improving the quality of the products with minimal costs for the introduction of the drug.

The problem is solved in that, as a complex substance - an iron-containing sorbent - and a source of trace elements - iron - when broiler chickens are fed, the Bifége serial veterinary preparation, developed and used earlier as an enterosorbent, is used for raising animals on feeds with a high radioactive content cesium prepared on a cellulose-containing carrier with a particle size of 0.16-2.5 mm

For its main purpose, as an enterosorbent for the removal of radioactive cesium from an animal’s body, Bifezh type preparations are used at a rate of 2-6 g per animal per day before morning feeding of sheep (see AS No. 1685372, A 23 K 1/00 Publish. October 23, 91. Bull. No. 39) or at the rate of 60-120 g per head for 10 months after calving to increase the degree of purification of dairy products of cows from infection with radioactive cesium (see AS No. 1704746, A 23 K 1/00. Publ. 15.01.92. Bull. No. 2).

In poultry farming and for broiler fattening, “Bitezh” has not been used as an iron-containing feed additive, which allows us to consider the proposed method as the use of the well-known preparation “Bitezh” for a new purpose with an unobvious effect in the form of an increase in live weight of broilers during growing.

The method of growing broilers is as follows. Chickens from 10 days of age, when switching to the main diet of fattening, are daily given the Bifézh drug in doses from 0.1 to 0.2 g / kg of live weight until the end of the feeding period, which improves the safety of the livestock and physical condition broilers, feed eatability improves and live weight gain increases while improving the quality of the products.

Veterinary preparation "Bifézh" refers to ferrocyanide-containing preparations (FSP), developed and used in animal husbandry when raising livestock in territories and feed contaminated with radioactive substances, and is commercially available according to TU 9337-002-25017929-97 with particle sizes corresponding to the particle size of the feed , and mixes easily with them.

The basis of FSP (ferrocyanide-containing preparations) is ferrocin, a finely divided powder consisting of potassium iron hexacyanoferrate KFe [Re (CN) ₆ ] (95%) (see Aleksakhin PM et al. Use of ferrocyanide-containing preparations in animal husbandry. Bulletin of the Russian Academy of Agricultural Sciences. - 1999, No. 1 P.15-17).

"Bitezh" is one of the most developed forms of PSF that are most suitable for feeding animals - a cellulose-inorganic composition obtained by precipitation of ferrocyanide - iron-potassium on a cellulose carrier (sawdust) in the form of a powder with particles of 0.16-2.5 mm in size ( ferrocin content up to 10%).

An experimental verification of the proposed method and assessment of its economic efficiency was carried out at agricultural enterprises of the Sverdlovsk region.

The amount of Biféj feed additive (dosage dose) introduced into the diet and the feeding schedule were previously determined by analogy with existing feed additives, based on an analytical review and laboratory experiments conducted at the Faculty of Animal Husbandry Technologies of the Ural State Agricultural Academy (Yekaterinburg).

The results of the production verification of the proposed method of broiler feeding are presented in examples 1 and 2.

Example 1. Scientific and economic experience was carried out on the basis of the Reftinskaya broiler poultry farm, where three experimental and one control group of chickens of 128 animals each were formed, of which 64 were cockerels and 64 chickens. The drug was given to experimental groups at a dose of 0.1; 0.15; 0.2 g / kg g.m., from 10 to 42 days. At the end of the experiment, zootechnical and biochemical parameters of muscles, tibia and liver were taken into account.

The results of the experiment are presented in tables 1 and 2.

Studies conducted in the experiment showed that the use of the drug "Bifezh" for a new purpose as a feed additive stimulates the increase in live weight, increases the safety of broiler chickens.

The lead content in the muscles of experimental chickens was 32.4% less than in the control, and in the second and third experimental groups the content of this element was lower than in the control by 46.6% and 45.3%, respectively.

In the experimental groups, the level of lead in males is lower than in the control, by an average of 24.5%.

In the liver in all experimental groups there was a decrease in lead content by 47.3% compared with the control.

A lower lead content was noted in the second experimental group (Bifézh 0.15 g / kg gm) in hens - 48.6% of the control, and in males - 41.1%.

The cadmium level in the liver of all chickens of the experimental groups is less than in the control group, on average by 10.9%.

In the study of broiler bones for the content of lead in them, there is a significant decrease in the content of this element in many experimental groups.

In experimental 1 in chickens and experimental 2 in males, the level of lead is lower than in the control group by 3.7 and 3.5 times, respectively. The cadmium content in the bones of chickens of all experimental groups is lower than in the control group by an average of 18.9%.

According to the results of this experiment, to continue the research, the dose of Bifézh administration was adopted 0.15 g / kg of live weight, as it showed the most stable results on the safety of broilers and increase in live weight.

Example 2. After analyzing the results of the first production experience in the period from 05/06/2001 to 06/16/2001, we tested the drug "Bifézh" as a means of increasing the productivity of broiler chickens on an industrial scale.

The experiment was carried out on broilers of the Smena-2 cross, based on the Reftinsky broiler poultry farm in the Sverdlovsk Region. Two groups of birds were formed: experimental and control. The chickens of the experimental group, in addition to the main diet, received Biefez at a dose of 0.15 g / kg body weight from 10 to 42 days. The birds of the experimental and control groups were kept in the cell growing system.

The test results of the effectiveness of the drug "Bifezh" on an industrial scale are given in table.3.

From table 3 it follows that as a result of using the drug "Bifézh" for the new purpose in the experimental group, the average daily increase in live weight increased by 3.1%, safety by 0.4%, and feed costs per unit of production decreased by 7.9% , which led to a decrease in cost by 2.9%. As a result, the profitability of growing broilers in the experimental group increased by 3.8% and amounted to 26.9%.

The data of experiments 1 and 2 indicate the economic efficiency of the use of the drug "Bitezh" when growing broilers.

The experiments and the above examples showed the technical feasibility of the proposed method and the high efficiency of the use of the drug "Bitezh" as a feed additive in the cultivation of agricultural broiler poultry, giving significant gains with minimal cost for use.
