Abstract:
In the last period, the poultry meat from other breeding systems than the industrial ones is increasingly being sought, which is why poultry farmers have used new hybrids and / or breeding technologies to meet this desire. For these reasons, we aimed to evaluate the quantitative production of meat in three hen hybrids (Ross-308, Hubbard and HB Color), reared according to the principles of slow growth and with slaughter at different ages (56, 63 and 81 days). After slaughtering, slaughter yields of 68.60-71.76% were obtained for the Ross-308 hybrid, 66.29-68.66% at Hubbard and 62.32-62.65% at HB Color. The cumulative weight of the two main components of the carcass (chest+thigs and drumstick) was 70.08-71.47% for the Ross-308 carcasses, higher by 1.60-3.23% compared to the situation from the Hubbard hybrid and by 6.92-9.21% than in HB Color. In contrast, the HB Color hybrid registered a high participation rate for wings (13.75-15.89%) and back (22.07-22.37%). In conclusion, it can be stated that the Hubbard hybrid provides good results in meat production (especially with slaughter at the age of 63 days) and which, in conjunction with other elements (productive performance, meat quality, etc.) recommends it for exploitation under slow growing conditions.
