Abstract

FIELD: poultry farming.

SUBSTANCE: method involves giving Phosprenyl in conjunction with water to birds for drinking, with Phosprenyl being added in an amount of 0.000001-10 ml/kg (0.004 mkg/kg-4,000 mkg/kg); giving Phosprenyl to broilers four times during one month; giving Phosprenyl to laying hens on transferring to parent flock, with first drinking being provided twice at 48-hour interval and further once a month up to the end of production peak.

EFFECT: increased resistance and immunity of birds, increased weight gain and yield of eviscerated broiler birds, laying capability and weight of laying hens.

Description

The present invention relates to the field of veterinary immunology, veterinary virology and bacteriology, in particular to the development of a method of increasing resistance and body immunity, keeping livestock, increasing weight gain and the output of gutted carcasses from broilers; egg production and egg mass in laying hens.

It is known that when the industrial content of animals and birds up to 80% of the livestock has acquired violations of the mechanisms of natural resistance and body immunity (acquired immunodeficiencies), which leads to loss of safety and productivity.

Acquired immunodeficiencies are: a) physiological (age-related, with high productivity); b) non-infectious pathological (during starvation and feeding disorders, metabolic disorders, hormonal disorders, stress, environmental changes (seasonal, toxic, radiation), the use of certain medications (vaccines, antibiotics, immunosuppressants, anthelmintics), violations of the content (microclimate, technological cycles, crowding, lack of exercise); c) pathological infectious (in acute and persistent viral infections, infections of the immune system, bacterial infections, dysbiosis, tozoic diseases, helminthiases).

The use of immunomodulatory agents in birds with acquired immunodeficiencies leads to an increase in the body's natural resistance and immunity, an increase in the body's adaptive capacity to stress factors, an increase in the efficiency and safety of vaccination, a decrease in the incidence rate and an increase in safety.

It is known that some of the immunomodulating agents simultaneously have a positive effect on the productivity of the bird (weight gain, egg production, etc.).

Known means for the prevention, treatment and elimination of the consequences of viral, bacterial, oncological diseases, diseases of the liver, gastrointestinal tract, genitourinary system, immune system, wounds, burns, stress, which contains polyprenols phosphate as the main active principle [1].

In veterinary medicine is known, approved for use and commercially available drug Fosprenil, which is a 0.4% solution of the product of phosphorylation of pine needles polyprenols.

It is known that the use of Fosprenil for broilers on the days of vaccination against viral infections has a positive effect on the level and duration of humoral immunity, livestock safety, growth, and meat quality [2].

The objective of our research was to develop a way to increase the resistance and immunity of the body, the safety of the livestock, increase the weight gain and the output of gutted carcasses from broilers, egg production and egg mass in laying hens using Fosprenil, regardless of vaccination.

This was achieved due to the fact that broilers and layers were treated with Fosprenil with water, in the dose range of 0.000001-10.0 ml / kg (0.004 μg / kg - 40,000 μg / kg) to broilers four times a month, and to layers when transferred to Rodilsky herd - the first milking twice with an interval of 48 hours, and then once a month until the end of the peak egg production.

Specific examples of the method and the results of its application are shown in table 1 and 2.

As can be seen from the data presented, the proposed method provides:

- at brokers of the Cross-Competitor-3 cross, by the 40th day of life (slaughter), their safety is increased by 2.7%, live weight by 304 g, and the output of gutted carcasses by 8.3%;

- in laying hens of Cross Hayseks white for 5 weeks of observation, an increase in safety by 0.6%, egg production by 4.44%, egg weight by 1.13 g, cumulative number of eggs per 10550 pcs., total egg weight 2.07 kg.

The proposed method allows you to use the property of polyprenol phosphates (in the form of Fosprenyl) to stimulate the synthesis of glycoproteins, among which biologically active and protective molecules of the body (hormones, immunoglobulins, cytokines), activating neuroimmunohumoral regulation of metabolism, immune response and natural resistance, which leads to: increase in meat and egg productivity of poultry, and in conditions of trouble, to reduce the incidence and increase safety.

The proposed method is economically justified and allows you to get 24.56 rubles profit per 1 ruble of the cost of the drug when growing broilers, and 3.78 rubles profit per 1 ruble of the cost of the drug when growing hens, only after 5 weeks of observation.

The proposed method was tested by us with a positive result in 2004-2005 on the livestock of chickens GUPPZ "Kuchinskaya" (Moscow region). Experiments were conducted on broilers in an amount of 720 goals. in the experimental and in the control group and layers in the amount of 2200 goals. in the experimental and control groups.

The method will find application in poultry farms of the Russian Federation and will improve the safety of livestock; increase the gain and yield of gutted carcasses of broilers; egg laying and egg mass in laying hens.

Claims (1)

A way to increase the productivity of the bird, namely, that the bird is drunk with water Fosprenil in the dose range of 0.000001-10.0 ml / kg: broilers four times a month, and for laying hens, when transferred to the parent herd, the first booze twice with an interval of 48 hours , and then once a month until the end of the peak egg production.
