| 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 change with aging, and it is worth-noting that age had positive effect on body weight, body length, thoracic circumference, anterior height and posterior height and negative effect on average daily gain. Average daily gain... |

| The objective of this study was to characterize the sexual development in Anglo-Nubian male goats raised in semi-intensive system. Eight animals were monitored every fifteen days, from the 12th to the 44th week for age at penis detachment, live weight, scrotal circumference, seminal parameters (volume, aspect, concentration, wave motion, progressive individual motility, vigor and spermatic abnormalities) and serum testosterone levels. Serum testosterone levels were determined in blood samples collected at the 20th, 28th and 38th weeks of age. Penis detachment occurred at 102.9 ± 15.4 days of age. Live weight and scrotal circumference at 20th and 44th weeks of age ranged from 25.9 ± 3.5 to 44.7 ± 4.7 kg and from 21.2 ± 1.6 cm to 26.0 ± 1.5 cm, respectively.... |
