BIOLOGICAL PECULIARITIES OF GROWTH AND DEVELOPMENT OF GOLSHTINSKY YOUTH OF AUSTRALIAN SELECTION

abstract 1361802031 issue 136 pp. 201 – 214 28.02.2018 ru 132
The article presents results of a comparative study of the experimental groups of Holstein animals belonging to the Reflection Sovering line: four groups of repair calves and four groups of bull-calves. The peculiarities of their growth and development were studied at higher daily rates of drinking milk and early training of experimental animals to plant feeds with a probiotic supplement of cellobacterins in the milk period. The technology of growing the animals of the experimental groups had differences: I-control group - up to 6 months of age was grown according to the traditional technology for farming: 200 kg of milk (for 50 days) and 400 kg of return (from 50 to 110 days), concentrated feeds consisted of starter feed (50%) and (50%) maize, the same amount of concentrated feed and the same composition was obtained by calves from experimental groups; II-test group - up to 6 months of age received an increased amount of milk (for 25 days) - 200 kg and 400 kg of return (from 25 to 60 days); animals of the III-rd experimental group - up to 6-month-old age received an increased rate of milk drinking (for 50 days) - 450 kg and return (from 50 to 110 days): heifers - 600, bulls -800kg. Animals of the IV-experimental group-up to 6 months of agereceived an increased rate of milking (for 60 days) - 450 kg and return (from 60 to 120 days): heifers - 600, bulls -800 kg. The calves of all experimental groups were fed a probiotic preparation of cellobacterin in an amount of 3 g for each animal up to 18 months of age. The live weight changed significantly depending on the age and the level of feeding of the experimental animals. The use in the feeding of calves of experimental groups of increased daily average milk yields and the addition of a probiotic to cellobacterin in the diet positively influenced the growth and development of experimental young animals, promoted a more intensive increase in live weight

INTERIOR FEATURES OF THE REPAIR YOUNG OF HOLSTEIN BREED

abstract 1351801030 issue 135 pp. 223 – 237 31.01.2018 ru 135
The results of a comparative study of the experimental groups of Holstein animals belonging to the Vis Bey Eidial line are given: four groups of repair calves and four groups of gobies. Their hematological indices were studied at higher daily rates of milk drinking and early training of experimental animals to plant feeds with a probiotic supplement of cellobacterins in the milk period. The difference between the groups was the technology of their cultivation: I-control group - up to 6 months of the age was grown according to the traditional technology adopted in the farm: 200 kg of milk (for 50 days) and 400 kg of return (from 50 to 110 days), and concentrated feeds consisting of pre-fodder (50%) and corn (50%), the same calves received experimental calves; II-test group - up to 6 months increased norm of milk drinking (for 25 days) - 200 kg and 400 kg of return (from 25 to 60 days); III-test group - up to 6 months the increased norm of drinking milk (for 50 days) - 450 kg and return (from 50 to 110 days): heifers - 600, bulls -800kg; IV-test group - up to 6 months an increased rate of milk drinking (for 60 days) - 450 kg and return (from 60 to 120 days): heifers - 600, bulls -800 kg. The calves of all experimental groups were fed a probiotic preparation of cellobacterin in an amount of 3 g for each animal up to 18 months of age. When the experimental animals reach 12-, 15-, 18-months age, hematologic examinations were carried out. It has been established that with the age of experimental animals, metabolic processes are intensified, the change of which was influenced by the use of different norms of drinking milk during the milking period, using a probiotic

THE CAUSAL AND INVESTIGATORY FACTORS OF FUNCTIONAL DISORDERS OF UTERUS AND OVARIES AT COWS ON INDUSTRIAL FARMS

abstract 1211607112 issue 121 pp. 1809 – 1817 30.09.2016 ru 471
According to the title, the article describes the causes and contributing factors of functional disorders of the uterus and ovaries at cows. The authors specified the percentage incidence of these animals’ pathologies in some farms of Krasnodar Region, especially in industrial complexes. Studies have shown that acute postpartum endometritis has a definite influence on the functional disorders of the ovaries at cows. Authors have found that the cows via 2-4 months after calving with ovarian hypofunction in early postnatal period have had purulent-catarrhal endometritis in 87.9%, fibrinous - in 12% of cases. At cows which have had persistent corpus luteum in 54.6% of cases was registered purulent-catarrhal endometritis, in 27.6% - fibrinous, in 17.8% - necrotizing metritis. At cows with ovarian cysts fibrinous endometritis was observed in 63.2% of cases, necrotizing metritis - in 36.7%. Thus, the more severe form of uterine inflammation was observed in cows, the more severe form of ovarian functional disorders observed in them. The authors found that any factors which negatively acting on the central nervous system or hormone levels, directly or indirectly, sharply reduce the reproductive function of animals
