| Sumario: | A study was conducted to assess the impact of heat stress on various carcass traits, meat quality variables and gene expression patterns which governs meat quality in indigenous female Kodi Aadu breed. The study was conducted for 45 days in climate chamber with 12 animals randomly allocated into two groups of six animals each, KC (n = 6; Female; Control), KHS (n = 6; Female; heat stress). Majority of the major carcass traits and meat quality variables remained intact between KC and KHS groups. The myostatin (MSTN), calpain 1 (CAPN1) and Diacylglycerol Acyltransferase 1 (DGAT1) mRNA expression patterns were significantly (P < 0.01) lower in KHS group as compared to KC group. However, the calpain 2 (CAPN2), calpastatin (CAST) and Crytallin alpha (CRYA) mRNA expression patterns were significantly (P < 0.05) higher in KHS group. Thus, the study established that the major carcass traits and meat quality variables remained intact after heat stress exposure in female Kodi Aadu goats. Further, MSTN, HSP27, CRYA and HSP90 genes were identified as biomarkers for reflecting meat quality during heat stress exposure in female Kodi Aadu breed. |
