Abstract
Saithanoo, S., Pralomkarn, W., Kochapakdee, S. and Milton, J.T.B. 1993. The pre-weaning growth of Thai native (TN) and Anglo-Nubian x TN kids. J. Appl. Anim. Res. 3: 97–105.
This paper presents results from a study of pre-weaning growth of Thai native (TN) and Anglo-Nubian (AN)xTN kids. The purpose of the study was to compare growth rate among genotypes of kids which were raised under improved management. Cross-bred (75% AN) kids had significantly higher growth rates (g/kg.75/d) from birth to weaning (12 weeks of age) and higher birth and weaning weights than other genotypes. Cross-bred (50% AN) kids had significantly higher growth rates than that of 25% AN and TN kids. There was no significant difference in growth rate between 25% AN and TN kids. Estimated daily milk yields from week 1 to weaning (week 12) for does rearing different genotypes of kids showed the same trend. The peak milk yield of the does occurred in weeks 3 and 7 of lactation. Cross-bred does (suckling 50% AN and 75% AN kids) had significantly higher milk yield than TN does (suckling TN and 25% AN kids). There was no significant correlation between milk available (ml/kg75/d) and growth rate (g/kg75/d) of the kids from birth to 6 weeks fo age.
