Abstract

The effects of sex and age on post weaning at different ages were investigated. Eighteen male and 18 female Sokoto Gudali calves were either weaned at 6 (n = 18) or 7 (n = 18) months of age. Vocalization activity and some behaviours (feeding, lying and walking / standing) were observed during the first 3 days following weaning. Body weight was recorded at 6 and 7 months and 2 weeks following weaning. Calves weaned at 6 months vocalized more often than calves weaned at 7 months and the females calves vocalised more than males on the first day (P < 0.05). The vocalization activity decreased at a higher rate in calves weaned at 7 months than in calves weaned at 6 from days 1 to 3. On day 2, calves weaned at 6 months spent less time lying and more walking / standing than calves weaned at 7 months (P < 0.05). Behaviours did not differ between males and females. Average daily gain after weaning did not differ between weaning ages (P > 0.05), but calves weaned at 7 months gained more from 6 to 7 months of age. In conclusion, weaning distress was more pronounced in calves weaned at 6 months than in calves weaned at 7 months. Calves weaned at 7 months also had a superior growth performance during 6 to 7 months of age. Form then results obtained in this study; it has been concluded that the effect of the calves' sex was less pronounced. It is recommended to wean beef calves later than 6 months.
