ABSTRACT The objective of this work was to use biometric measurements to predict carcass characteristics of lambs of the Morada Nova breed. We used 48 lambs with mean initial body weight (BW) of 15.0±0.04 kg and slaughter body weight (SBW) of 26.37±2.43 kg. The animals were weighed weekly and underwent a period of adaptation of 15 days before slaughter. The biometric measurements were obtained the day before slaughter, comprising body length, withers height, rump height, thigh length, breast width, rump […]

The aim of this study was to compare the genetic diversity of 12 populations of goats in Brazil and Morocco (n = 796) through the use of physical measurements and different multivariate techniques. Traits measured included wither height (WH), distance from the brisket to the ground (BH) and ear length (EL). The standardized Euclidean distance (D) was adopted. The D values were submitted to clustering analysis using hierarchical methods (from nearest neighbor and UPGMA – Unweighted Pair Group Method with […]

The present study investigated the effect of calving season on puberty of Santa Inês ram lambs raised in the Distrito Federal, Brazil. Thirty-three ram lambs were assigned to four contemporary groups according to birth date, distributed in three months intervals. Data were collected monthly and every 15 days depending on the presence of sperm in each animal ejaculate. Puberty was defined when the animal presented total motility of 10% and sperm concentration of 50 x 106 per mL of ejaculated […]
