DIFFERENTIAL TREATMENT OF INCUBATING EGGS OF MEAT CHICKEN BREEDS

abstract 1031409078 issue 103 pp. 1150 – 1159 30.11.2014 ru 480
Differentiation of temperature influence on embryos at incubation of eggs shows positive results: the output of chickens is synchronized, duration of embryogenesis is reduced, deductibility of eggs raises, the young growth output increases

GENETIC PECULIARITIES OF SYMMENTAL LIVESTOCK DROPPED OFF INTO FARMS OF THE KRASNODAR REGION

abstract 1081504041 issue 108 pp. 568 – 580 30.04.2015 ru 578
Farms of Krasnodar region purchase cattle of milk, combined and meat direction of productivity. Imported cattle are accompanied with documents which differ from analogous ones specified in such cases by pedigree service of Russia. There were studied 1000 heads of symmental cattle of milk-meat direction of productivity imported from Austria. More than 5000 kg of milk can be obtained from cattle of symmental breed of milk-meat direction of productivity, except it they show enough high meat productivity. The analysis of accompanying documents on purchased cattle is joined not only with language barrier but with the lack of knowledge of adopted abbreviations, contractions and other attributes used by foreign breeders abroad. Having studied the accompanying documents connected with hereditary information of purchased cattle there was determined that imported heifers and their mothers were obtained in Austria, and mothers of bulls on 55,5% obtained in Austria and 41,6% in Germany. So, on formation of imported micropopulation of cattle greatly influenced the breeding school of Germany. In accordance with the adopted classification in Austria due to revealed cases of adoption of Holstein blood, there is a ground to consider the present herd as a belonging to the group of pure breed of symmental cattle and in prospect to conduct the mating of cattle with pure breed symmental oxen with the aim of absorption of mixtures of Holstein blood in pedigree. The researches determined that one can purchase the producers with characteristics of milk productivity at daughters of oxen not lower than Austrian indexes on voluminous milking and German – on milk quality, the purchase of symmental cattle from other countries must be subjected to this demand.

METHOD OF SELECTION OF QUAILS

abstract 1381804034 issue 138 pp. 140 – 148 30.04.2018 ru 5
The article is devoted to the method of selecting quails. Intensive development of re-fishing requires the development of breeding methods for selecting birds and to carry out early predictions of egg production. Targeted breeding selection is able to influence the mechanisms of correlation dependencies between individual parts of the animal's organism, significantly change even firmly established interrelations, and create new interactions more satisfying the needs of the individual. The research task consisted of establishing links between the parameters of the skeleton and the productive qualities of the layers. The studies were conducted on Texas white quails. We took into account the live weight of the bird, the length of the metatarsal and the third finger, as well as the small and large diameters of the metatarsal. Correlations were established between the length of the pelvic limbs and the live weight of young quails during growth. It is established that the growth of the skeleton ends with the age of onset of puberty. This provides a basis for predicting the live weight, depending on the length of the pelvic extremities. It is established that the live mass is directly related to the egg productivity of quails. Thus, by selecting the birds with the longest plus, it makes it possible for 25 weeks of productivity to increase the egg laying on the initial layer by 5,7 eggs and 6,2 eggs per average laying hen, respectively

SYNCHRONIZATION OF THE HATCHING AT THE ARTIFICIAL INCUBATION

abstract 1351801032 issue 135 pp. 238 – 253 31.01.2018 ru 2
The embryo passes a number of the stages caused by high-quality structural changes in development and following them growth periods. The periods of change of development for the periods of growth are critical and are most sensitive to influence of external factors. The developed differentiated mode provides sharp temperature increase of incubation in the critical periods of development of an embryo. High temperature at separate stages of an incubation has displaced metabolic processes of the developing embryo towards lipidic exchange, at the same time the cholesterol indicator in blood of skilled chickens has grown more than twice, and level alkaline phosphatase by 2,5 times. Synchronization of the hatching was reached due to reduction of the periods embryonic and output on about 10-12 of hours. Operating an embryogenesis in the period of incubation there is an opportunity to influence the level of productional processes of chickens during the post-embryonic period, average daily gains of live weight at cultivation of broilers increase on average by 5-7%

THE FORMATION OF HIERARCHICAL STRUCTURE OF ANIMALS IN A CLOSED SPACE

abstract 0901306047 issue 90 pp. 708 – 724 30.06.2013 ru 1079
The article presents the results of the research of the formation of hierarchical structure in a group of roosters while being in the close space of a cage. Stable hierarchical relationships in the group could only be formed with a certain amount of roosters included in it
