Effect of slaughter weight on slaughter performance of a native swine breed “Ghungroo” of Duars’ Valley and allied zone

Ghungroo (GR) is a native pig breed which is mainly reared by the tribes of Duarsʹ Valley and allied zone. To assess the breedʹs performance more comprehensively, a research work had been planned to evaluate the effect of slaughter weight on slaughter performance by dividing 18 GR pigs in three groups (viz. 40-50 Kg, 5060 Kg and 60-70 Kg) having six animals in each group. Hot Carcass Weight, Dressing Percentage, Chilled Carcass Weight, Loin Eye Area, Back Fat Thickness, Carcass Length, shoulder weight, ham weight and loin weight increased significantly(P<0.01) while shoulder percentage, ham percentage, loin percentage and head percentage decreased significantly (P<0.01) with the increase in slaughter weight
