Description

A way to increase the productivity and quality of sheep products.

The invention relates to sheep farming, and in particular to methods of increasing the productivity and quality of sheep products.

A known method of growing lambs (see the magazine "Sheep, goats, wool" No. 4, 2005, p. 38-41), where the lambs were fed 100-150 g dietary supplements "Alexandrite" per head per day, depending on age. For 240 days of experience, the average daily gain of rams was 124.8 g.

The task is to increase the productivity of animals and the quality of sheep products.

For this purpose, animals from 10 days old are fed probiotic preparations of the Vetom 1.1 or Vetom 3 series with food. The drug is fed at a dose of 50 mg / kg body weight 3 times a day for 3 days with a 3-day break for 2 months.

Probiotics are a new promising class of pharmacology. Immuno-and growth-promoting effects allow the use of probiotics as a means of prevention, as well as as feed additives to increase the gain in live weight and reduce the period of feeding animals. Probiotics are produced in the form of dry preparations, dried microorganisms in pure form or in technical form with a forming base. As the fillers for the first use milk powder, glucose. Vetom-1.1 and Vetom 3 are characterized by high activity to a wide range of pathogenic and conditionally pathogenic microflora due to the properties of Bac. Subtilis, stimulate cellular and humoral factors of immunity and increase nonspecific resistance of the body.

Execution example.

A research experiment was conducted in the Karasuksky district of the HCO, at the Department of Pharmacology and General Pathology of the NSAU and in the Novosibirsk Interregional Veterinary Laboratory.

The object of the study was lambs, selected on the basis of analogues. 2 experimental and 1 control groups were formed. The first experimental group received Vetom 1.1, the second experimental group received Vetom 3. Sheep from the control group received no drugs. The duration of the experiment is 240 days. During the study, all animals were in the same conditions. The feeding ration of all groups of experimental animals included meadow hay, oats, bran. Conducted daily monitoring of the general condition of the animals, behavior, consumption of feed and water.

Vetom 3 Control group M ± m M ± m M ± m Live weight at the beginning of the study, kg 4.2 ± 0.1 5.2 ± 0.2 5.4 ± 0.25 Live weight at the age of 240 days, kg 47.93 ± 0.40 43.6 ± 0.53 34.43 ± 0.81 The average daily gain in live weight during the study period, g 181.3 ± 21.01 159.3 ± 9.02 120.3 ± 10.02

To study the effect of the drug on the growth rate, the absolute weight and daily average growth were determined.

Lambs, which were used by Vetom 1.1 and Vetom 3, in absolute weight exceeded analogues from the control by 39.2% and 26.6%, the average daily increase was 50.7% and 32.4%, respectively.

All experimental animals had high indicators of meat productivity (Table 2).

As follows from table 2, the sheep of the first and second experimental groups of paired carcasses exceeded the analogues from the control group by weight by 36.5 and 25.4%, by slaughter yield - 16.7 and 9.2%, respectively.

The meat yield exceeded 31.5% and 22.04%, respectively.

The sheep of the 1st experimental group in terms of the amount of internal fat exceeded the analogues from the control group by 159%, and the sheep of the 2nd experimental group had a decrease of 22.9% (Table 2).

In the lamb meat of the first experimental group, which was used Vetom 1.1, there was a slight decrease in protein by 0.54%, an increase in fat and ash by 3.4% and 4.2%, respectively. In meat in sheep of the 2nd experimental group receiving Vetom 3, the protein and fat content were higher by 6.18% and 8.18%, respectively, and the ash content was lower by 2.7% compared to the analogues from the control group (table .3).

The moisture content in the mass of the animal of the 1st and 2nd experimental groups was lower relative to sheep from the control group by 0.3 and 6.1%.
