BREEDING, SELECTION, GENETICS

4-9 43
Abstract

The article examines the dynamics of the number of sheep in different areas of productivity, production of wool, lamb and sheep’s milk over the past 20-30 years in the world and Russia.

Abstract

The article shows the prospects and great potential opportunities for the development of sheep breeding in the Trans- Baikal Territory and Republic of Buryatia in the Far Eastern Federal District (Far Eastern Federal District), the leading position of these regions in the presence of sheep. In the Trans-Baikal Territory and the Republic Buryatia is concentrated, respectively, 57% and 36% (93% in total) of the sheep population. Thus, there are significant competitive advantages in the development of the industry, the production of mutton and wool within the Far Eastern Federal District. The necessity of integration and joint actions of the above-mentioned regions is substantiated, proposals are formulated and made in The Ministry of Agriculture in the Russian Federation, to other executive and legislative authorities for the development of sheep breeding.

Abstract

The article presents the dynamics of the breeding stock of Romanov sheep in Russia and the Yaroslavl region, the characteristic of productivity is given. The complex of measures carried out by the breeding center in order to preserve the gene pool of Romanov sheep and improve their productive qualities is given.

Abstract

The article presents data on changes in the fertility of Akzhaik meat-wool semi-fine-fleeced sheep for the entire reproductive period of their life. The results of long-term observations have shown that the fertility of sheep changes with age. The lowest fertility was observed in the queens of the first lambing and the greatest - at the age of six at the fourth lambing.

SHEEP AND GOAT PRODUCTS

Abstract

A study was carried out of the influence of feed starters enriched with protein and carbohydrate-mineral feed additives “Organic” and “LaktuVet” of the processing industries of the agro-industrial complex on meat productivity and quality of lamb of meat and wool sheep under the age of 4 months.

Abstract

The article presents the results of measuring the wool tone of996 samples obtainedfrom the main sheep of five fine-fleeced sheep breeds bred in breeding plants of the Stavropol Territory. The tests were carried out in the laboratory for testing and certification of wool belong to the All-Russian Scientific Research Institute of Breeding, Testing was carried out on an OFDA-2215 device. A significant range of variation in fibre diameter between different animals of individual farms flocks was found - up to 11.2 pm. Between pedigree farms flocks of different breeds of sheep of Stavropol region wool variation ware from 21.47 to 24.43 pm. Wool of rams of all breeds has not big variation of fiber diameter in the staple and in the fleece and corresponds to the requirements of the Russian standard № 26383-84.

Abstract

The positive influence of year-round stabling (in comparison with stabling-pasture) on the formation of skin and wool cover: the total thickness of skin and its separate layers, the density of hair follicles, physical and technical properties and wool shearing has been established in sheep of the Prekos breed. The studied technology in growing of repair young sheep is acceptable in conditions of sheep breeding farms of the Central Black Earth zone.

FEED, FEEDING, FEED PRODUCTION

42-44 54
Abstract

The state of metabolic processes in the body of lambs was studied when they were fed brown algae Fucus vesiculosus L. The positive effect of brown algae on the physiological state of the body with the improvement of biochemical and hematological parameters of the blood of experimental lambs has been established.

Abstract

The results of studies on 4 groups of fattening rams of the Dagestan mountain breed on the study of selenium supplements in diets deficient in this element are shown. It installed, that the lack of selenium in the feed of young sheep in the south of Dagestan reduces the digestibility of nutrients in diets and the rate of body weight growth. The optimal level of DAFS-25 additive (15 mg/1 kg) in the feed of 3-9 month old rams installed.

DISEASE PREVENTION

49-53 63
Abstract

The purpose of the study is to prepare a review of modern ultrasound methods for diagnosing pregnancy and infertility in goats, based on literature data. For the review, scientific articles published in the bibliographic databases E-library and Scopus were used. It has been shown that visual echography is a safe and highly informative research method that makes it possible to accurately diagnose infertility and pregnancy in goats, determine the timing of gestation, predict the number and sex of gestatedfetuses, conduct dynamic monitoring of their growth and development throughout almost the entire pregnancy, as well as clearly differentiate physiologically developing pregnancy from false pregnancy, which is important for practical veterinary medicine.

54-57 25
Abstract

The article is devoted to the experience gained in using goats and sheep to rescue from forest fires against the background of drought. Studies have been conducted on the use of sheep for modeling dangerous situations and the development of evacuation measures. Animals with a strong balanced type of nervous system adapt faster and easier to adverse stress factors. Sheep adapt well to sudden temperature fluctuations, but at the same time they need certain conditions to maintain their health and productivity.
