Article Synopsis
  • The study examined how the milking reactivity of primiparous Saanen goats impacts their welfare and milk production during lactation.
  • Goats were observed for signs of reactivity on multiple days, and results showed a decrease in reactivity over time as they became accustomed to milking.
  • It was found that less reactive goats produced milk with a higher fat percentage, but overall, there were no significant stress indicators related to milking during early lactation.

Heat stress during lactation affects the physiological responses, hormonal release, health, and productivity of dairy cows. However, the adverse effects of heat stress on milk synthesis, immune response, and cellular apoptosis in mammary cells remains unknown in Bos indicus cows. This study aimed to understand the relationship between milk yield, milk quality, and the expression of genes related to milk synthesis, cell apoptosis, and immune response in mammary cells of Girolando cows.

Objective: To evaluate the pattern of eye-gaze of preterm (PT), autism spectrum disorder (ASD) and neurotypical (Ty) children.

Methods: A cross-sectional study with eight preterm (born with ≤2000 g weight), nine ASD and five Ty male children, between six and nine years old, was performed. The eye gaze was evaluated presenting a board with a couple in social interaction, and a video with four children playing with blocks, projected in a screen computer, successively, evaluating the time that the children looked at each stimulus.
