Evaluation of various biochemical stress markers and morphological traits in different goat breeds at high-altitude environment

High-altitude the region represents the extreme climatic condition that may have an adverse effect on body weight and alteration in stress markers of livestock animals. Thus, the aim of our study was to evaluate different morphological traits and biochemical stress markers in different breeds of the goat at Leh-Ladakh, India. In this study, 27 adult female goats of three different breeds like Changthangi-a native breed of high altitude, Sirohi-a low lander breed from the plain area, and Crossbred-Changthangi x Sirohi. After 330 days of rearing, a comparative assessment of the seven different morphological traits and seven biochemical stress markers were analyzed. The MDA level and LDH activity of crossbred goat were significantly (p <= 0.05) lower than Changthangi and Sirohi breeds. However, CAT, FRAP, % DPPH, GSH, and beta-carotene were found significantly higher in the crossbred as compared to Sirohi and Changthangi breeds. In addition, a significant progressive rise in body weight of crossbred was observed as compared to both the pure breeds. The study concludes that prolonged exposure of high altitude has a lesser adverse effect on the crossbred goat that may be due to an effective body adaptive mechanism against high-altitude-induced oxidative stress.

Automated summary

The study evaluated morphological traits and biochemical stress markers in different breeds of goats at Leh-Ladakh, India. The results showed that the crossbred goats had lower levels of MDA and LDH activity, but higher levels of CAT, FRAP, % DPPH, GSH, and beta-carotene compared to purebred goats. Additionally, the crossbreds showed a significant increase in body weight compared to purebreds, suggesting a lesser adverse effect of high altitude on crossbred goats due to an effective adaptive mechanism against oxidative stress.
