The objective of the study was to assess the variability in the physiological responses of growing pigs on melatonin and vitamin E supplementation during summer and winter seasons.36 nos. of weaned crossbred (Hampshire X Assam local) female pigs were selected for the study. Eighteen (18) animals were subjected to treatment separately during summer and winter. The selected animals were divided into three groups, with six pigs in each group, consisting of the control group (Treatment 1), a second group comprising of animals fed with melatonin (Meloset) @3 mg/animal (Treatment 2) and a third group in which the animals were fed Vitamin E (Evion) @100 mg (Treatment 3), for both the seasons. The rectal temperature, respiration and pulse rate differed significantly(P<0.01) between seasons. Therewas also significant difference (P<0.01)in themean pulse ratebetweentreatment.
