The objective of this study was to characterize body biometrics of Santa Ines sheep during growth. Data from 4,038 animals, males and females, with ages from four to 36 months, from different herds participating in the National Agricultural Fair in Bahia from 2003 to 2008 were used. The characteristics evaluated were: body weight, average daily gain, body length, thoracic circumference, anterior height and posterior height. The mean values found were compared by the Student-Newman-Keuls test. All characteristics studied showed gradual […]

The objective of this trial was to evaluate performance (weight and weight gain), body measurements, feed conversion, and production costs of purebred (Alpine) and crossbred [½ Boer + ½ Alpine (½ BA) and ¾ Boer + ¼ Alpine (¾ BA)] goat kids at different ages (60, 90 and 120 days). Therefore, 41 kids in a feedlot system were used in this study. Data were submitted to analysis of variance using the Tukey test for comparison of means. No difference in […]

The objective of this experiment was to evaluate the performance of crossbred Charolais x Nellore young steers fed diets with different corn hybrid silage: Agroceres AG9090, Dekalb DK440 or Braskalb XL344. Animals were feedlot finished until reaching approximately 430 kg of body weight. The average age of the animals at the beginning and at the end of the trial was 10.3 and 15.2 months, respectively. Diets were formulated to contain a forage:concentrate ratio of 60:40 (DM basis) with the following […]

The objectives of this study were to estimate the genetic trends and also the genetic and phenotypic parameters for body weight at 378 days (W378), body measurements and scrotal circumferences of Nellore males from selected and control populations of the Estação Experimental de Zootecnia de Sertãozinho (SP), Brazil. The heritability estimates, considering sire and animal model were, respectively, 0.53± 0.12 and 0.36 for W378 days; 0.38±0.11 and 0.58 for hip height; 0.31±0.10 and 0.10 for chest girth; 0.40± 0.11 and […]

The objective of this study was to evaluate the indirect effects of selection for post-weaning weight on body measures and scrotal perimeter of 809 Nellore males from selected herds (NeS and NeT) and control herd (NeC), of the Estação Experimental de Zootecnia de Sertãozinho. The statistical analyses were performed by using a sire mixed model where the random source of variation, sires, was nested within herds. The fixed effects were herds, year of performance test (PGP), age of cow and […]
