COMPARISON OF SLAUGHTER YIELD AND CARCASS TISSUE COMPOSITION IN BROILER CHICKENS OF VARIOUS ORIGIN
Keywords: broiler, Ross, Hubbard, JV, slaughter yield
AbstractSlaughter yield and carcass tissue composition were compared in three different broiler chicken production sets. The highest body weight (1892.5 g), eviscerated carcass weight with neck (1406.9 g) and slaughter yield (74.5%) were found in Ross 308 chickens, whilst the lowest values of these traits occurred in JV chickens (respectively: 1753.3; 1288.2 g; 73.3%). The highest muscle contents (45.4% breast muscles and leg muscles in carcass) and the lowest fattiness (7.9% skin with subcutaneous fat and 1.5% abdominal fat) were found in Hubbard Evolution chickens.
