Resumo: | An analysis was made of the duration of survival of kids that eventually died within 360 days of their birth in the tropical North-East Brazil. These kids belonged to three breed groups: indigeneous (Moxotó, Marota, Canindé, Repartida), exotic (Bhuj, Anglo-Nubian) and SRD (Sem Raça Definida or nondescribed). The results showed that the size of kid at birth was most important and that there was significant difference between breed groups in the duration of survival. Type of birth alone had no effect and therefore if the weight of kid was as good as those of single born kids, the twins may survive equally well. Maximum mortality (37% of total) occurred within first five days of birth and tendend to increase again around 90 days. The results suggest that the single most important factor influencing survival may be the condition of the mother at the time of parturition, which may be improved either by supplementary feeding or by shifting the breeding season in such a way that the kids are born when the mothers are generally in good condition. |

Os cabritos pertenciam a três grupos de raça: nativos (Moxotó, Marota, Canindé e Repartida), exóticos (Bhuj e Anglo-Nubiano) e SRD (Sem Raça Definida ou não descritos). Os resultados mostraram que o tamanho do cabrito ao nascer foi o fator mais importante no tempo de sobrevivência, o qual também foi diferente significativamente entre os grupos de raça. O tipo de nascimento apenas, não teve influência significativa na variável analisada; e por isso, se o peso do cabrito fosse tão bom quanto aquele dos cabritos nascidos de parto simples, os nascidos de partos gemelares poderiam sobreviver igualmente bem. A mortalidade maior ocorreu dentro dos primeiros cinco dias de idade (37% do total) e tendeu a aumentar novamente por volta dos 90 dias de idade. Os resultados sugerem que o fator mais importante influenciando tempo de sobrevivência pode ser a condição da matriz na época do parto, podendo essa condição ser melhorada, tanto fornecendo-se alimentação suplementar às matrizes, como ajustando-se a estação de nascimentos, de tal maneira que os nascimentos ocorram quando as matrizes estejam em boas condições.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPant, K.P.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15895Pesquisa Agropecuaria Brasileira; v.17, n.5, maio 1982; 803-808Pesquisa Agropecuária Brasileira; v.17, n.5, maio 1982; 803-8081678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/15895/9984info:eu-repo/semantics/openAccess2014-04-16T13:28:09Zoai:ojs.seer.sct.embrapa.br:article/15895Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T13:28:09Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
