Estimation of genetic parameters, and genetic and environmental effects on progeny carcass traits of a nucleus breeding population in Japanese black cattle

Estimation of genetic parameters, and genetic and environmental effects on progeny carcass traits of a nucleus breeding population in Japanese black cattle

Genetic parameters of body weight at the start of fattening (BSF), carcass weight (CWT), subcutaneous fat thickness (SFT), rib thickness (RBT), meat quality grade (MQG), beef marbling score (BMS) and rib eye area (REA) in Japanese Black cattle were estimated. The effects of genetic and environmental...

Zusammenfassung:Genetic parameters of body weight at the start of fattening (BSF), carcass weight (CWT), subcutaneous fat thickness (SFT), rib thickness (RBT), meat quality grade (MQG), beef marbling score (BMS) and rib eye area (REA) in Japanese Black cattle were estimated. The effects of genetic and environmental factors on fattening performance and carcass quality traits of the progeny were also analyzed. The averages of BSF, CWT, SFT, RBT and REA were 189 kg, 408 kg, 24.9 mm, 69.3 mm and 47.5 cm2, respectively. CWT was significantly affected (Rho
