Conteúdo:  A new method of transcribing visually-recorded behavioural data is described, to facilitate rapid computer processing; it is applied to a total of 31 animals (bulls, cows and calves) in the Markham Valley, Papua New Guinea. There is no evidence of seasonal variation. Approximately one-third of grazing is carried out at night, so that night yarding is not indicated without further investigation. Total times spent in recorded activities are comparable with those for temperate climates. There is evidence for an effecta of breed, in that animals with more than half-shorthorn ancestry show a marked reduction in mid-day grazing.

Conteúdo:  Abstract: The success of IVF and subsequent development of embryos are directly related to sperm selection and quality. This study aimed to evaluate the effect of different forces and time of centrifugation in mini-Percoll (MP) techniques for sperm selection on capacitation status and plasma membrane (PM) integrity of ram frozen-thawed sperm. Commercial semen from 10 rams of Santa Inês breed, aging 2-5 years old, were used. At post-thawing (PT), the PM integrity was evaluated by CASA using the SCA® system (Sperm Class Analyzer ? Microptic Automatic Diagnostic Systems, Barcelona, Spain). For traditional Percoll (Sigma Chemical, St. Louis, USA), a 2 mL-gradient (90/45% density) was subjected to a 700 x g centrifugation for 10 min followed by 200 x g for 5 min. The MP techniques consisted in an 800 µL-gradient (90/45% density) subjected to either: I) two centrifugations of 5000 x g for 5 min; II) two centrifugations of 2500 x g for 5 min; III) two centrifugations of 1250 x g for 5 min; IV) 700 x g for 10 min, followed by 200 x g for 5 min. At the end of all treatments, aliquots (post-protocols = 0 h) were taken for evaluation of PM integrity and capacitation status by chlortetracycline stain (Sigma Chemical, St. Louis, USA). Later on, samples of all treatments were submitted to incubation at 37°C, 1 h, 2 h and 3 h and the same parameters were assessed. The variables were subjected to either ANOVA or Kruskal-Wallis tests depending on normality, Tukey and Fisher-LSD analysis (P <... Mostrar Tudo
