Growth and meat productivity of limousin cattle under the condition of stable system in Central Chernozemie region of Russia
The analysis of growth and meat productivity of the growing stock of Limousin cattle under the condition of stable system in Central Chernozemie region of Russia has been carried out. 2 groups of animals were formed according to analogue pair method taking into account their age and live weight to conduct the experiment. The article presents the analysis of intravital assessment of growth intensity of bulls and heifers according to the results of dynamics of live weight change in cattle with regards to age aspect. It was determined that during the time of development (1-19 months) live weight of bulls exceeded that of heifers by 160.2 kg or 25.9%. Special aspects of development during various physiological periods were identified. Evaluation of meat productivity, which is formed in well-developed animals with strong skeletal frame and excellently formed muscular tissue, was carried out according to the results of control slaughter at the age of 19 month taking the following into account: pre-slaughter live weight, hot carcass weight, carcass yield, internal fat weight and yield, slaughter weight, and slaughter yield. High slaughter yield (62.0%) was connected to more pronounced development of muscular tissue in carcasses, which is an individual characteristic of beef breeds of cattle of French breeding.
