Conteúdo:  Animal preparation prior to artificial insemination (AI) in goats usually involves a combination of intravaginal devices containing progesterone/progestagens plus PGF2?? analogues and gonadotropins, being eCG the most used. The use of intravaginal devices soaked in synthetic progesterone analogues requires milk discard for 60 days. Progesterone soaked intravaginal devices, as synthetic ones, are associated with more animal handling and discomfort. In addition, it leads to environmental impacts because it generates more residues. On the other hand, eCG has presented continuous restriction due to animal welfare issues associated with its production (Vilanova et al., Animals, 9:1053, 2019) and it has been substituted by hCG for this purpose. This study tested the efficiency of estrus induction by light program followed by estrus synchronization protocol with two doses of cloprostenol 7.5 days apart and gonadotropins to provide suitable condition able to support fixed time AI (FTAI) during the non?breeding season in dairy goats.

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
