Growth and development of bulls of different types of productivity

The article provides data on the weight growth of bulls of different types of productivity. The growth and development of Black-and-white, Simmental and Aberdeen-Angus bulls were studied during the period of their rearing and feeding. The change in live weight was established, the dynamics and growt...

The growth and development of Black-and-white, Simmental and Aberdeen-Angus bulls were studied during the period of their rearing and feeding. The change in live weight was established, the dynamics and growth rate of the studied bulls were calculated depending on the breed and type of productivity. The research results showed that the Aberdeen-Angus bulls had the highest live weight during fattening - 485.2 kg, which was significantly higher than that of the Black-and-White and Simmental breeds by 68.7 kg (p <0.001) or 14.0% and 19.7 kg (p <0.01), or 4.1% respectively.

It was found that the type of productivity had a certain effect on the dynamics of live weight, the intensity of growth and development of animals.Donetskikh AlexandrGrikshas StyapasPastukh OlgaKorenevskaya PolinaKertiev RuslanEDP SciencesarticleMicrobiologyQR1-502PhysiologyQP1-981ZoologyQL1-991ENFRBIO Web of Conferences, Vol 37, p 00040 (2021)
