Abstract: Indigenous breeding practices of the farmers and the livestock production system form the bases for designing community-basedbreeding programs. The aim of this study was to characterize production system and examine breeding practices of the indig-enous goat farmers in Hai district in Northern Tanzania to determine their relevance in establishing a community-based breedingprogram in the area. A cross-sectional survey was conducted in which information was collected from 160 households randomlyselected from 6 villages. Average household herd was 29.2 goats with majority keeping less than 20 goats. Major reasons forkeeping goats were income generation, meat and milk production. Controlled mating was practiced mainly using apron andcastration. Castration was practiced using traditional methods to control breeding and improve meat quality. Farmers in the studyarea had large goat flocks and a small buck to doe ratio. Farmers do not have a good understanding of inbreeding and its negativeeffects but practise other good breeding methods which could impact the productivity of their animals. Diseases and feedshortages were the main constraints to production. Opportunities exist for a community-based breeding program to geneticallyimprove goat productivity. |

A seleção recorrente e a técnica de melhoramento que aumenta a frequência dos genótipos favoráveis em uma população, através da aplicação cíclica de intercruzamentos e seleção. No Brasil, a seleção recorrente esta sendo utilizada no melhoramento de populações de arroz irrigado, visando a extração de linhagens com potencial produtivo superior ao das variedades atualmente cultivadas, associado a outras características agronômicas favoráveis. |
