abstract
The research was conducted to study the effect of supplementing Tinospora cordifolia (TC) in the diet of Gaddi goats exposed to heat stress. Total Sixteen adult male Gaddi goats were divided into four groups T0H0 (no supplement no heat stress, control), T1H0 (animals fed on diet supplemented with TC stem powder @ 5% of DMI with no heat stress), T0H1 (no treatment with heat stress) and T1H1 (animals fed on diet supplemented with TC stem powder with heat stress). Experiment was arranged in 2×2 factorial in which supplementation (0% versus 5%) and heat stress (normal versus heat exposure) were the main effects to be investigated. Temperature humidity index (THI) value was calculated as 29.42 which designated the experimental animals were in severe heat stress. Rectal temperature had no significant differences among the supplemented and non supplemented groups but individual interaction of heat stress showed significant (P<0.05) increased respiration and pulse rate. Interaction of supplementation and heat stress did not affect rectal temperature and pulse rate but respiration rate significantly (P<0.05) reduced in T1H1 as compared to T0H1. Daily intake of nutrients were changed by the individual effect of heat stress (P<0.05). Dry matter and neutral detergent fibre (NDF) digestibilities in diets were affected by individual effect of heat stress (P<0.05), however supplementation of TC did not affect digestibility of any nutrient.
