Measurements “in vivo” and of carcasses and constituents non-carcasses of sheep fed with different levels of guava agroindustrial by-product

<p></p><p>SUMMARY The objective of this study was to evaluate the biometrics, morphometry and the organs do non-constituents of the carcass of feedlot Santa Inês sheep fed with increasing levels (0; 20; 40 and 60% dry matter basis) of guava agroindustrial by-products as a replacement for corn. Forty male (noncastrated) Santa Inês sheep, averaging 17.41 ± 1.27 kg body weight (BW) and 120 days of age at the beginning of the study, were used in this trial. The animals were slaughtered at 32 kg or 105 days of confinement. A completely randomized design with ten replicates per treatment was used. The animals submitted to diets with 60% substitution showed lower body length (63.20cm), lower withers height (67.30cm) and hip (69.50cm), low body condition score (2.40 pts), lower carcass of conformation (2.25 pts), lower chest perimeter (65.10cm) and low yields of organs such as heart (0.52%), spleen (0.15%), kidneys (0, 25%) and lung (0.89%). Corn can be replaced by guava agroindustrial by-product at levels up to 40%, being relevant to obtain animals with body characteristics desirable for meat production and yield of organs non-constituents of carcass satisfactory to the market.</p><p></p>
