Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

Synergistic Benefits of Butyric Acid and Resistant Potato Starch on Growth and Gut Health in Weaned Pigs

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Newly‐weaned piglets face challenges such as reduced feed intake, impaired gut function, and susceptibility to post‐weaning diarrhoea, increasing the need for dietary strategies that support gut health and growth. This study investigated the effects of dietary supplementation with butyric acid (BA), resistant potato starch (PS), and their ...
