| Abstract: | The objective of the current study was to observe the impact of two seasons viz. summer (February–May) and monsoon (June–August) on the blood biochemical and hormonal responses in different indigenous goats of tropical island agro-ecological environment maintained under extensive management system. Sixty animals of three different indigenous goat breeds were included in the study: Andaman local goat (AL, n = 20), Andaman local?×?Malabari (AL?×?M, n = 20), and Teressa goat (n = 20). Sixty serum samples (n = 10/season/breed) from the three groups of animals were analyzed. Study revealed that there was a significant increase (p ≤ 0.05) in serum total protein in Teressa goats during summer than monsoon. Serum albumin showed significant variation (p ≤ 0.05) between AL and AL?×?M during summer whereas significant variation of albumin (p ≤ 0.05) was observed between AL and Teressa, AL?×?M and Teressa during monsoon season. Significant differences in serum albumin (p ≤ 0.05) were also observed in AL and AL?×?M during summer and monsoon seasons, respectively. The serum cortisol levels were significantly higher (p ≤ 0.05) in AL goats during summer than in monsoon season. Thus, the study could able to establish the seasonal variation in biochemical and hormonal values of indigenous goat breeds in hot and humid tropical island environment. |
