Resumo

Twenty-five adult crossbred goats, divided in two groups, were fed over a period of 16 months with diets based on Tifton hay and concentrate feed with (DCO) or without (WDCO) detoxified castor bean meal as a substitute for soybean meal. Throughout 480 days, blood samples were taken to measure lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, urea, albumin and creatinine. The animals were euthanized, and the anatomical components (lungs, heart, spleen, liver, kidneys, tongue, empty stomach, empty intestines, omentum, cardiac and renal adipose tissue), carcass and commercial cuts (shoulder, ham, loin, ribs and neck) were weighed. Thereafter, an anatomic dissection of the loin was performed, separating the muscle, adipose and bone tissues. On the muscular part of the loin, longissimus dorsi, the proximate composition, fatty acid profile and the expression of SEW-1, IGF-I and IGF-II were analyzed. A higher incidence of bone tissue was observed in the anatomical dissections of the loin and a lower incidence of fat in the proximate composition of the longissimus dorsi of the DCO group compared to the WDCO group (p<0.05). The expression of the IGF-II and SEW-1 genes was higher (p<0.001 for each) in the muscle tissue of the DCO animals. Thus, using detoxified castor bean meal for long periods does not produce significant changes in the anatomical composition of the loin or the proximate composition of the longissimus dorsi. However, the differences in gene expression suggest the need for new investigations and care when using this product for animal feeding.
