The research has established that the cross-bred young bulls received from the crossing of the cows of Southern beef breed with the bulls of Limousin breed showed the intensive growth from birth to 18 months of age during the whole period of growing and fattening.
For instance, at the age of 3 months their average live weight was by 7.04% higher than that one of pure-bred bulls. This trend remained the same at the age of 7, 12 and 15 months when the difference between these groups was 6.37%, 8.37% and 7.35%, respectively, in favour of the cross-bred young bulls. At the end of fattening period, the live weight of the cross-bred young bulls of Southern beef and Limousin breeds was by 10.46% higher as compared to the pure-bred ones.
The cross-bred young bulls in all age groups had higher average daily gains. The difference between groups during the period from birth to 3 months of age was 10.84%; from 3 to 7 months of age – 5.74%; from 7 to 12 months of age – 13.59% (td=2.64; P≤0.05); from 12 to 15 months of age – 4.70%; and during the final fattening period from 15 to 18 months of age this difference was 22.14% (td=3.91; P≤0.01). Throughout the whole growing and fattening period, the cross-bred young bulls of the experimental group exceeded the pure-bred ones (td=3.39; P≤0.01) in average daily gains by 11.22% (95.5 g).
The cross-bred young bulls in all age groups had a well-defined advantage in meat forms and dimensions.
The analysis of dimensions has shown that the average wither height at birth of Southern beef young bulls was by 1.43% lower than of those received from the crossing of the cows of Southern beef breed with the bulls of Limousin breed. At the age of 7 months, this difference slightly increased to 1.49%, while by the end of fattening period it reached 2.28%. Such a significant difference by the other dimensions has not been observed between the groups.
A slight difference between the pure-bred and cross-bred young bulls, in favour of the latter ones, was observed in width dimensions, in particular, in rear body dimensions: hook-bone width (3.01-10.31%); hip-joint width (2.90-5.10%); gluteal humps width (5.46-7.78%) and rear semi-circumference (0.44-9.70%). The cross-bred young bulls had higher oblique body length (0.91-2.83%) indicating the hereditary influence of the Limousin breed.
