Observational analysis assesses live weight differences in young beef cattle, indicating breed impacts.
The study of the dynamics of the live weight of young cattle of beef breeds was carried out in the production conditions of the Agricultural Limited Liability Company "Ratnivsky Agrarian" of the Volyn region. Interbreed, age and sex characteristics of the formation of the live weight of animals of the Volian and Polissiyan вeef breeds were established. In all periods taken into account for the analysis, the animals of the Polissiyan вeef breed prevailed over their counterparts of the Volian Beef breed. The advantage of bulls ranged from 0.4 to 4.8 kg, heifers – from 0.3 to 14.8 kg. Also, in general, for all studied age periods, the advantage of heifers of the Polissiyan Beef breed in terms of absolute and average daily live weight gains was from 1.2 to 13.3 kg and from 38.5 to 63.5 g, respectively. In terms of the multiplicity of live weight increase, heifers of the Polissiyan beef breed in all age periods were superior to heifers of the Volian beef breed by 0.3 times. The patterns of live weight formation depending on the sex of the animals were determined. The highest difference was found in the first month of weaning from mothers: bulls of the Volian Beef breed outweighed heifers by 40 kg, Polissiyan breed – by 30 kg.
