Abstract

ABSTRACT
The aim of this study was to determine the effect of administration of ascorbic acid on rectal
temperature of Red Sokoto goats exposed to heat stress during the early raining season. Ten
goats of both sexes served as subjects for the study. Five goats(experimental) administered with
ascorbic acid (AA) per os at a dose rate of 100 mg/kg thrice, a week apart. Five goats
administered with distilled water per os served as controls. Rectal temperature (RT) was
collected from an hour after each administration of ascorbic acid through 13thhour. The goats
administered ascorbic acid had a consistently lower RT values than those of control goats
throughout the study period from 1hr – 13hr post administration of ascorbic acid. The lowest
hourly temperature of 37.0±0.270C was obtained in experimental goats at 12hrs post
administration, while the highest value of 38.1±0.330C was recorded at 1hr post administration.
The overall mean values of RT in control and experimental Red Sokoto goats were 38.00 ±
0.090C and 37.55 ± 0.080C, respectively (P < 0.05).The goats administered ascorbic acid had a
consistently lower RT values than those of control goats throughout the study period from 1hr –
13hrs post administration.Thus, the administration of ascorbic acid may be beneficial to goats
during the early rainy season as it reduces the negative effects of thermal environmental stress on rectal temperature.
