In this work, linear body measures were taken and production indices calculated for 100 Cuban Creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in Cuba. Low variation was found for all indices of the Creole goats, showing homogeneity between the groups of animals studied. Most of the functional indices are related to the milk biotype which is in agreement the possible origin of the breed from animals of the Iberian Peninsula […]

Estudou-se a diversidade genética de pacas (Agouti paca) de três plantéis comerciais no Brasil. Como o genoma desta espécie é desconhecido, utilizaram-se o polimorfismo de DNA amplificado ao acaso e reação em cadeia da polimerase (RAPD-PCR). Dez primers selecionados geraram 60 bandas polimórficas. A variabilidade genética inter e intrapopulações estimada pela análise de variância molecular (AMOVA) foi de 12,55 e 87,45%, respectivamente. A menor distância de Nei encontrada foi de 11,76% entre as populações de Carangola (CG) e São Francisco […]

Most livestock are not indigenous to Brazil. Several animal species were considered domesticated in the pre-colonial period, since the indigenous people manage them as would be typical of European livestock production. For over 500 years there have been periodic introductions resulting in the wide range of genetic diversity that for centuries supported domestic animal production in the country. Even though these naturalized breeds have acquired adaptive traits after centuries of natural selection, they have been gradually replaced by exotic breeds, […]
