SUMMARY:

Sheep farming in integrated crop-livestock systems is presenting itself as a sustainable production option for the Brazilian semi-arid region. With these advances, it not only responds to growing demands to reduce the environmental impacts of livestock farming, but also contributes to the expansion of sheep farming. The aim of this study was to evaluate the crop-livestock integration system in the Caatinga biome, the carcass characteristics, morphometrics, yields of commercial cuts and the non-carcass component of sheep in a crop-livestock integration system in the Caatinga biome. The experiment was conducted in an area of Caatinga that had been thinned and enriched with tree, shrub and herbaceous pasture. The treatments consisted of three integration systems: 1.beans (cultivar BRS Pujante) grown in the Caatinga; 2.corn (cultivar BRS Catingueiro) grown in the Caatinga; and 3.herbaceous cotton (cultivar BRS Aroeira) grown in the Caatinga, as well as a control treatment: 4.only Caatinga. A total of 24 (six per treatment) F1 Santa Inês x Dorper sheep were used, with an average initial body weight of 24.64 ± 2.95 kg. A randomized design was used with four treatments and six repetitions (sheep). The crop integration system increased body weight at slaughter, hot carcass weight, cold carcass weight and true carcass weight (P<0.05). There were no differences in the morphometric measurements of the carcass. There were differences in the shoulder and shank cuts (P<0.05). There was no treatment effect on pH, but there was an effect at post-mortem. The crop-livestock integration system in the Caatinga biome and the Caatinga pasture had no effect on organ weights and the weight of gastrointestinal components in sheep (P<0.05). There was no difference in pork belly yield (P>0.05). It is proposed that the implementation of this type of integrated system in Caatinga pasture optimizes the carcass characteristics and commercial cuts of F1 Santa Inês x Dorper sheep.
