Comparative Study of Fruitfulness of Cow Insemination of a Milking Herd at Various Levels of Productivity in the Conditions of Bayserke-Agro LLP

Application of Medical and Hygienic Agents in Prevention of Lameness and Treatment of Hoof Diseases in Cows

“…After the application of the Prevention-N-E biological preparation, the terms of the onset of estrus, the insemination index and the service period were reduced in animals, as well as the fertility rate at the 1st insemination. The obtained data are consistent with the research of Kazakhstani scientists in the Bayserke-Agro conditions regarding the prevention of gynecological diseases and increasing the productivity of cows [7,8,9].…”

Productive Longevity and Reproductive Quality of Holstein Cows of Foreign Breeding

“…When studying the adaptive process of imported livestock, a specific criterion is a reason for the premature withdrawal of imported animals [10]. In our studies, the main reasons for the premature withdrawal of cows were: gynecological diseases, which on average accounted for 4.2%; various forms of metabolic disorders -3.6%; diseases of the extremities -1.56%; mastitis -1.28% and low productivity -0.76%.…”

“…The quality of imported livestock does not always meet the requirements. Therefore, studies on the productive and reproductive qualities of cows of different genotypes within industrial technology are very relevant [7,8,9,10,11].…”

Reproductive Qualities of Cows With the Application of Biological Preparations

“…Results. The main indicators of the air basin, both in the cowshed and in the maternity ward, were within the zoohygienic standards: T, °C -9.9±0.24 and 14.9±0.41; R,% -71.3±1.11 and 70.0±0.67; v, m/s -0.29±0.07 and 0.21±0.07; microbial content, thousand/m 3 -41.6±1.47 and 29.3±1.13; concentration of NH 3 , mg/m 3 -14.1±0.60 and 7.9±0.33; the level of H 2 S, mg/m 3 -8.3±0.27 and 3.7±0.21; the amount of CO 2 ,% -0.17±0.01 and 0.15±0.01; solid aerosol content, mg/m 3 The natural illumination in the indicated premises for cows with geometric standardization (light factor) was 1:15 and 1:14, and with lighting standardization (coefficient of natural illumination) it was 0.71±0.03 and 0.86±0.05%, respectively.…”

“…The duration of the operation of cows reaches 3-4 lactations. The causes of these problems can be poor feeding of animals depending on their physiological state in terms of nutrients, vitamins and minerals, poor-quality veterinary services and violation of hygienic conditions of maintenance, illiterate operation of animals, faults in organizing artificial insemination and the technology for growing the herd, and many others [3,4,5].…”
