The invention relates to agriculture, in particular to animal husbandry, and can be used in feeding young cattle. The purpose of the invention is to increase the productivity of animals. For bulls with an interval of 15-17 days for 90 days, the thymus homogenate is injected subcutaneously in the neck at a dose of 0.03-0.045 ml per 1 kg of animal weight and fed a diet treated with enzyme preparations pectofoethidine and alumo-amylase once a day a dose of 18-30 units. and 0,009 units. on 1 head. Pectofetidine is first introduced into the feed, the mixture is stirred, irrigated with a 1% glucoamylase solution, incubated for 1-2 hours and fed to animals.

Description

The invention relates to agriculture, in particular to animal husbandry, and can be used in feeding young cattle.

The purpose of the invention is to increase the productivity of animals.

PRI me R. By the well-known principle, groups of bulls are selected by 10 heads in each group with a live weight of 310-319 kg.

The conditions of keeping animals are the same, the microclimate parameters meet generally accepted standards. The duration of the experiment is 90 days. The feeding ration for all groups of animals contained 9.4 k.e. and 940 g of digestible protein.

The difference between groups of animals is. that thymus homogenate was subcutaneously administered to animals of the experimental groups twice in the neck area with an interval of 15–17 days and fed once a day to a ration treated with enzyme preparations pectofoetidine and glucoamylase. Processing feed ration enzyme preparations are as follows.

Pectofoetidine is added to the feed ration. the mixture is stirred, irrigated with a 1% aqueous solution of glucoamylase, stirred again, and after 1-2 hours of exposure, fed to animals.

The experimental design is presented in & l. one.

From the data table. 1 it follows that the dose of injections of the homogenate was 0.03-0.045 ml per 1 kg of animal weight, glucoamylase 0.009 g (9 units /) and pectofostidine 6-10 g

(18-30 units, /) on 1 head.

The results of experiments on the effect of thymus homogenate and enzyme preparations on the productivity of animals are presented in Table. 2

As can be seen from the data table. 2. increase in live weight of animals to whom thymus thromus is administered at a dose of 0.03-0.045 ml per 1 kg of live weight and fed a diet ration treated with glucoamylase at a dose of 0.009 g (9 units /) and pectofoetidine at a dose of 6-10 g (18-30 units /) per 1 head, amounted to 431.6-448 kg or 123.7-136.4% compared with the control group of animals. The average daily weight gain of bulls was 1318-1453 g per day ..

The results of biochemical analyzes of blood serum of young cattle of experimental groups with double administration of thymus homogenate with an interval of 15-17 days (M ± t, n 7) are given in tab, 3.

According to the data. 3, the content of gamma globulins increased, especially on day 3 after administration of the thymus homogenate, after which there is a tendency to decrease it.

Increasing the content of gamma globulins is particularly important, as it is one of the main factors of humoral immunity. The total fairness increased by 5–8% by 3–10 days compared with the control animals, but by day 30, the content was normalized,

Therefore, repeated administration of thymus homogenate to young cattle on days 15-17, after the first, helps to maintain total protein, gamma globulin, and lipids in blood serum at a higher level, which indicates a more active metabolism in the body.

Hematological parameters under the influence of factors of thymus homogenate with the introduction of its 8 animal body undergo certain changes.

With a single injection for 3-10 days, the number of erythrocytes increases by 5-10% and hemoglobin by 7-12%, but by 15-20 days, these figures decrease to the level of control animals. Repeat

drug administration during the period of decline in these indicators, i.e. on days 15-17, allow them to be maintained at a higher level for 2.5-3 months, i.e. to end

fattening

Immunological parameters in animals under the action of thymus hormones undergo significant changes, especially cellular immunity. -When a single injection of the drug is the activation of cellular immunity, but for 15-20 days, the indicators tend to decrease. The introduction of the drug on the 15-17 day prolongs a higher level of T-cell and humoral immunity.

Claims (1)

Claims method of growing young cattle, providing processing the basic ration with enzyme preparations and feeding it with animals, characterized in that, with the aim of increasing the productivity of animals, before feeding animals with the main the ration treated with enzyme preparations, they additionally administered thymus homogenate at a dose of 0.03-0.045 ml per kg of live weight twice with an interval of 15-17 days, and pectofetidine at a dose of 16-30 units is used as enzyme preparations. and glucoamylase in a dose of 9 units. on the head, and the processing of the diet with enzyme preparations is carried out sequentially by mixing the feed ration with pecto Fotidine, irrigate the resulting mixture with a 1% aqueous glucoamylase solution and allow the mixture to stand for 1-2 hours before feeding.
