Selection for leanness and carcass quality

摘要: Publisher Summary This chapter examines the published studies on carcass qualities of genetically fat and lean lines discusses distribution in carcass, slaughter characteristics, meat yields, organoleptic characteristics. The most adverse effect excessive fatness is development a large pad abdominal cavities birds. Hence, direct selection against fat, using sib-test procedures, was undertaken France by Leclercq, Blum Boyer, Israel Cahaner Nitsan, Netherlands Leenstra Pit. One main problems associated with arises from need to birds measure directly precisely. means technique, such as sib test, which prevents being kept for breeding purposes, has be used, but this slow expensive method selection, hence, search indirect live measurements sufficiently correlated content. also presents an experiment, divergent experiment 1977 obtain chickens its results. results r demonstrated possibility selecting broilers.
