| Summary: | The aim of work – to determine efficienty of the Lithuanian Black-and-White cattle crossing with Charolais bull. The task of research: 1.To analyse the literature about the crossing Lithuanian Black-and-White caws with Charolais bull. 2.To determine the influence of Charolais bull on beef meat production and quality of Lithuanian Black-and-White cattle. Conclusions: 1.Charolais bulls were found to improve the weight of Lithuanian Black-and-White cattle at 18 month of age by 38.5 kg or 7.6 % (P>0,05) and reduced feed conversion per weight gain unit by 8.2 %. 2.The daily gain of the Charolais hybrids bulls was by 8.0 % bigger than that of the pure-blooded Lithuanian Black-and-White bulls. 3.Control slaughters indicated the bigger carcass mass for Charolais hybrids which was 20.7 kg, or 7.8 % bigger than the carcass mass of the pure-blooded Lithuanian Black-and-White young bulls. 4.Hybrids had a 1.5 % better carcass output, 4.0 % better ham output, and 2.4 % better output of ham edible parts in carcass, by 0.65 bigger the coefficient of succulence of this part of carcass and by 42.94 cm² bigger area of loin lean. 5.Crossbreeding had no significant influence on meat quality. A tendency was observed to lower meat pH, higher shear force and a better amino acids triptophan and oxyproline ratio 5.47 of hybrids (P<0,005). 6.It has been concluded that it is useful to use Charolais bulls for crossing with Lithuanian Black-and-White cattle of milk type.
