- Carcass measurements, non-carcass components and cut production of local Brazilian Pantaneiro sheep and crossbreeds of Texel and Santa Inês with PantaneiroPublication . Vargas Junior, Fernando Miranda; Martins, C.F.; Pinto, Guilherme dos Santos; Ferreira, Marcos Barbosa; Ricardo, Hélio de Almeida; Leonardo, Ariádne Patricia; Fernandes, A.R.M.; Teixeira, AlfredoThis study aimed to assess and compare the non-carcass components, carcass measurements and meat cut production of Pantaneiro (P) sheep and their Texel (TP) and Santa Inês (SIP) crossbreds. Ninety-six lambs, of which 51 were male and 45 were female, with a mean weaning weight of 15.21 ± 1.25. kg and age of 78 ± 13 days were slaughtered at 32. kg of body weight. TP lambs had greater leg compactness and weight and percentage of pelt, whereas genotypes (G) P and SIP had higher carcass depth. P and SIP females had weights omental fat percentages that were superior to the other animals, whereas SIP females had higher mesenteric fat. TP males had higher production of white viscera. There was no effect of sex, G or interaction for production and percentage of all meat cuts. Pantaneiro lambs and their crosses with meat breeds could be useful in meat production systems under Savannah environmental conditions.
- The effect of sex and genotype on growth performance, feed efficiency, and carcass traits of local sheep group Pantaneiro and Texel or Santa Inês crossbred finished on feedlotPublication . Vargas Junior, Fernando Miranda; Martins, Charles Ferreira; Pinto, Guilherme dos Santos; Ferreira, Marcos Barbosa; Ricardo, Hélio de Almeida; Leão, André Gustavo; Fernandes, Alexandre Rodrigo Mendes; Teixeira, AlfredoThis study aimed to assess and compare the growth performance, feed efficiency, and carcass traits of Pantaneiro sheep and their Texel and Santa Inês crossbreds. Ninety-six lambs, fifty-one males, and forty-five females, with a mean weaning weight of 15.21±1.25 kg and 78±13 days of age, were slaughtered at a 32-kg body weight. The results showed better production efficiency from males compared with females. Texel-crossed lambs had a better growth performance than the other genotypes. The Texel×Pantaneiro lambs were more efficient with a better feedlot performance, higher ribeye muscle area, and better carcass characteristics with an adequate amount of fat cover. Pantaneiro lambs and their crosses with meat breeds could be useful in meat production systems under Savanna environmental conditions.
