The objective of this study was to evaluate the influence of crossings between sheep breeds on the intrinsic quality of leather. It was used the skins of 36 lambs (18 females and 18 males), resulting from crosses between ewes of a native breed from the Brazilian state of Mato Grosso do Sul and rams of the same native breed as well as the Texel and Santa Inês genetic groups. The animals were raised in confinement until slaughter weight, from 28 […]

This work had as objective to evaluate the physical-mechanic characteristics of the leather from one genotype of sheep and three genotypes of goat. Forty three tanned chrome skins were used: 9 Santa Inês sheep, 12 ½ Anglo Nubiano, 16 ½ Boer, all crossbed with animals of non-defined breeds (NDB) and six NBD native goats. In the pre-experimental period, all animals were weaned at 90 days of age approximately and raised under semi-intensive production systems using cultivate pasture. The experimental phase […]

The objective of the study was establishing the anatomical-structural differences between the skin of non-wool sheep of the Morada Nova breed and wool-on sheep of the Polwarth or Ideal breeds and their relations to the physical-mechanical characteristics of their leather after tanning. Ten animals of both breeds were used, with five animals of approximately one and four years of age of each breed. The animals were slaughtered, and immediately after skinning, samples were taken viewing the microtomy of the skin […]
