This study examined the effects of incorporating biochar into broiler diets on productive performance and physiological status. In total, 240 unsexed one-day-old broiler chicks were divided into three treatments, each with four replicates of 20 chicks. The first group received a basal diet without biochar (control). The second and third treatments received the basal diet supplemented with 1.5% and 3% biochar, respectively. The...

This study investigated sex ratios in Japanese quail ( Coturnix japonica ), a valuable model for other poultry species due to its rapid generation interval. The study examined the impact of selection over generations, age at first egg (AFE), and body weight at AFE (BW AFE ) on offspri...
