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... |

Objetivou-se estabelecer a zona de conforto térmico para ovinos da raça Santa Inês por meio da comparação das respostas fisiológicas em diferentes opções de temperatura em câmara bioclimática. O experimento teve duração de 71 dias e foi conduzido utilizando-se sete borregas da raça Santa Inês por tratamento. Os tratamentos foram as faixas de temperatura de 10, 15, 20, 25, 30, 35 e 40°C, com três repetições (dias de exposição) e cinco dias de intervalo. O delineamento experimental utilizado foi o inteiramente casualizado. Os dados meteorológicos coletados foram temperatura de bulbo seco, temperatura de bulbo úmido e temperatura de globo negro e os fisiológicos, frequência respiratória, frequência cardíaca, temperatura retal, temperatura timpânica, taxa de... |

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.... |
