This study was designed to investigate the effects of fasting for 4 days, directly after exposing the animals to two levels (30 and 60%) of feed restriction for 6 weeks, on the physiological performance of Nubian goats. Twelve male Nubian goat kids (2-3 months of age) were divided into three equal groups according to the level of feed restriction; A (30% feed restriction), B (60% feed restriction) and C (control, ad libitum feed consumption) for 6 weeks. Then, the three groups were exposed to fasting (100% feed restriction) for 4 days, followed by re-feeding for 1 week. During the fasting phase, previous exposure of the animals to the two levels of feed restriction did not exert any significant difference in water intake, body weight and body temperature compared to the feeding ad libitum. Ad libitum feed consumption and 30% feed-restricted groups showed significant (P<0.05) increase in haematocrit (PCV) during the fasting phase compared to 60% feed-restricted group. The previous feed restriction significantly (P<0.05) decreased hemoglobin (Hb) concentration during the re-feeding phase compared to the fasting phase. The feed-restricted groups revealed a slight increase in erythrocytes count during the fasting phase. These results indicate that feed restriction prior to starvation periods can enhance the ability of Nubian goats to tolerate the adverse effects of starvation.
