| Popis: | The aim of this study was to evaluate the effects of the inclusion of the seaweed Gracilaria birdiae (GB) in the diet of dairy goats on their performance and physiological variables. Eight Saanen goats were distributed into two Latin squares (4 × 4). The diets tested were four levels of inclusion of the seaweed GB at different concentrations (0, 4, 8 and 12%). No significant differences were observed as consequence of seaweed levels on dry matter intake and milk production. However, the respiratory rate, rectal temperature and surface temperature were significantly reduced due to the inclusion of GB, suggesting that the seaweed GB may alleviate the effects of the high environmental stress faced by dairy goats. The inclusion of GB in the diet of lactating goats does not affect milk production but can contribute to the attenuation of the deleterious effects of heat stress when the ambient temperature rises. |
