Abstract
In this paper, we aimed to study the influence of genotype and season on sperm production in beef cattle sires in Kazakhstan. Based on the results obtained over five years of using beef cattle sires, it can be considered that the spring and summer periods have a significant impact on Kazakh Whiteheaded sires; the winter and summer periods affect Aberdeen-Angus sires, and the spring period affects Hereford sires. Other seasons mainly had a positive influence on sperm production indicators, and if there were any changes, they were not significant. The highest concentration in the ejaculate was observed in Kazakh Whiteheaded sires during the winter-autumn period, amounting to 0.82 billion/ml; in Aberdeen-Angus sires during the spring-autumn period, it was 0.72-0.72 billion/ml; and in Hereford sires during the autumn period, it was 0.82 billion/ml. Autumn had a positive influence on all genotypes.
期刊介绍：
The Journal of Animal Behaviour and Biometeorology (ISSN 2318-1265) is the official journal of the Center for Applied Animal Biometeorology (Brazil) currently published by Malque Publishing. Our journal is published quarterly, where the published articles are inserted into areas of animal behaviour, animal biometeorology, animal welfare, and ambience: farm animals (mammals, birds, fish, and bees), wildlife (mammals, birds, fish, reptiles, and amphibians), pets, animals in zoos and invertebrate animals. The publication is exclusively digital and articles are freely available to the international community. Manuscript submission implies that the data are unpublished and have not been submitted for publication in other journals. JABB publishes original articles in the form of Original Articles, Short Communications, and Reviews. Original Articles arising from research work should be well grounded in theory and execution should follow the scientific methodology and justification for its objectives; Short Communications should provide sufficient results for a publication in accordance with the Research Article; Reviews should involve the relevant scientific literature on the subject. JABB publishes articles in English only. All articles should be written strictly adopting all the rules of spelling and grammar.
