Resumo: | Data from 1215 kids, with 402 Saanen, 396 Alpine, 200 Toggenburg and 217 ½ Alpine goats, was collected on growth of goats in the Federal District, Brazil from 1995 to 2001. For variance analyses were considered as fixed effect farm, breed, sex, kidding type, month and year of kidding and weight of dam as a covariable. Traits as birth weight and growth from birth to weaning and weaning to first insemination were studied. There was a significant effect of breed, sex and type of kidding on birth weight while weaning weight was only influenced by breed. Month and year of kidding were significant in influencing growth rate after birth. Number of days to insemination weight was influenced by both breed and month of kidding while the insemination weight itself was not influenced by any of the factors studied. Insemination weight was lowly correlated with the other traits in the study, as was to be expected. Days to insemination weight was most highly and negatively correlated with growth rate after weaning and weaning weight showing that faster growing animals that were larger at weaning reached insemination weight more quickly. The correlation between weaning weight and growth rate after weaning was low indicating that animals heavier at weaning did not necessarily grow faster after weaning. Key words: Correlation, growth curve, heritability, housed, weight. |

Consideraram-se, como fixos, os efeitos de raça, sexo, número de crias, mês e ano de parto e, como covariável, o peso da cabra, para análise das características peso ao nascer e à desmama, ganho de peso do nascimento à desmama e da desmama à primeira inseminação, bem como idade à primeira inseminação. O peso ao nascer teve relação com a raça, o sexo e o número de crias. Já o peso à desmama, apenas com a raça. O mês e ano de nascimento afetaram o ganho de peso após à desmama. O número de dias para inseminação foi influenciado pela raça e mês de nascimento. As correlações genéticas estimadas entre o peso ao nascer e as demais características evidenciaram-se altas e positivas, exceto em relação ao ganho de peso do nascimento à desmama (0,23). Quanto às correlações obtidas entre o ganho do nascimento à desmama, observaram-se correlações altas e positivas, porém foram altas e negativas no que diz respeito ao número de dias para a inseminação (-1,0). As correlações estimadas entre ganho de peso da desmama à primeira inseminação se apresentaram altas e positivas. Em geral, os resultados indicaram que animais que cresceram mais rápido foram maiores à desmama e às idades posteriores. As herdabilidades estimadas mostraram-se moderadas, indicando que a seleção deve produzir animais com rápido crescimento e que atinjam idade de reprodução com menor idade.
