Influence of types of constitution on meat productivity bullets of Simmental breed

The aim of the research was to establish quantitative and qualitative indicators meat productivity Simmental bull calves various constitutional types when raised using technology beef cattle breeding. maximum growth rate highest yield products were obtained from bulls dairy type they fed according Receiving mothers for 205 days sucking period more fatty milk, gave 1250 g gain per day reached 289.7 kg live weight by cut. Having retained a high in future, at final fattening 1321 20 months 659.3 kg. superiority Simmentals over analogues natural 3.4–13.3% steamed carcass, 0.4–1.8% slaughter yield, 1.4–11.1 terms amount pulp carcass bones 0.1–0.3 kg, protein 0.12; 1.19; 2.59 energy 0.14; 0.44; 1.75 MJ. also have ability transform feed into carcass.
