Abstract
- This paper aimed to assess the improvement of beef production using industrial crossbreeding. The research was conducted on 101 individuals allotted in four groups, L1-Romanian Spotted cattle (RS) - control 1; L2 Limousine (L) x Romanian Spotted cattle; L3-Romania Black and White cattle (RBW) - control 2 and L4-Limousine x Romanian Black and White cattle. Body development of half-bloods from experimental groups was higher than the maternal breeds, showing pronounced aptitudes for beef production, especially in L x RS cross, which performed a body weight by 18 months old of 689.37 kg (+14.36% compared to maternal breed). An obvious improvement of beef yield was registered also in L x RBW group (603.13 kg live weight at 18 months old, +15.38% vs. the maternal breed). BS x L half-bloods had an average daily gain above 975 g, fitting into the beef morphological type. In the study, we found a good ability of body development for half-bloods and a pronounced heterosis effect compared to maternal races. [ABSTRACT FROM AUTHOR]
