Calcium levels and evaluation of bone and egg of breeding ostriches

Analyses of mineral density in tibias and femurs of breeder ostriches had been carried on six couples 5-7 years old. During 8 weeks, 3 couples had been fed with ration of reproduction (T1) and other 3 couples with ration of maintenance (T2). It was possible to verify that the egg production was not...

Zusammenfassung:Analyses of mineral density in tibias and femurs of breeder ostriches had been carried on six couples 5-7 years old. During 8 weeks, 3 couples had been fed with ration of reproduction (T1) and other 3 couples with ration of maintenance (T2). It was possible to verify that the egg production was not affected by the diets, as well as the quality of egg shells. However the quality of the bones was worse for the birds fed of T2. Realizaram-se análises da densidade óssea em tíbias e fêmures de 6 casais de avestruzes reprodutoras com idade entre 5 a 7 anos, alimentados durante 8 semanas, 3 casais com ração de reprodução (T1), e 3 casais com ração de manutenção (T2). Verificou-se que a produção de ovos não foi afetada pelas dietas, assim como a qualidade da casca dos ovos. No entanto a qualidade dos ossos foi pior para as aves do T2.
