Biometria, morfometria e composição regional da carcaça de caprinos e ovinos de diferentes genótipos - DOI:10.5039/agraria.v11i3a5384

The objective of this study was to evaluate the biometric, carcass morphometric and the regional composition of different genotypes of sheep and goats Without Defined Racial Standard (WDRS) and mestizos of Boer and Dorper, respectively, grazing in the Caatinga. This work was developed in Pendencia Experimental Station belonging to the Agricultural Research Corporation of Paraiba S.A. Were used 40 male animals, not castrated, with average age of 120 days and average initial weight of 18.76 kg. The animals remain under grazing in the bush with power of native forage and water disposal and protein salt ad libitum. The WDRS sheep showed higher values for forward height (FH) and posterior height (PH). Body length (BL), the WDRS sheep gained superiority, with similarities to the Dorper crossbred and smaller values for the WDRS goats and Boer crossbred. The half carcass weight, leg, loin and neck yield were significantly different in genotypes (P 0.05). The crossbred sheep Dorper with body measurements obtained better than the crossbred goats or Without Defined Racial Standard.
