Present study was conducted for 30 days on twelve adult male goats (24-28 months age, 24.21±1.23 kg live weight), randomly divided into two groups (n=6), to investigate the effect of irregular feeding schedule on blood biochemical profile. Goats were kept on ad libitum wheat straw with regular feeding of concentrate mixture at 9:30 AM (Control, C), whereas in treatment group (IR), an irregular feeding schedule of concentrate mixture was followed (10:00 AM, 12:00 PM and 14:00 PM). The blood samples were collected from all experimental animals at the end of feeding trial. Levels of glucose, total protein, albumin, T3 and T4 were similar in both the groups. But serum cortisol level (nm/l) was found significantly higher (P<0.01) in IR group (34.25±0.46) in comparison to C group (25.20±1.28). It can be concluded that animals of IR group suffered a bit stress as indicated by increased cortisol levels.
