Diallel analysis for bodyweight involving three genotypes of Nigerian indigenous chickens

Abstract To evaluate heterosis, reciprocal effect, general and specific combining abilities for bodyweight, a diallel crossing experiment was conducted using three genotypes of Nigerian indigenous chickens: normal (N), frizzle (F) and naked-neck (Na). A total of 601 chicks was hatched from all possible matings between the three genotypes. The chicks used in this study were hatched from a foundation stock of 90 chickens comprising 25 hens and 5 cocks for each of the three genotypes. A mating r...

Relationship among cane rat (Thryonomys Swinderianus) families of unknown genetic origins in Ibadan Nigeria

Population of wild cane rats decline in African countries due to high rate of hunting, destruction of their natural habitats and high demand for cane rat meat. Subsequently cane rat has been classified among the threatened and endangered wildlife (Aluko et al., 2015) in the West African sub-region. Global concerns over hunting of endangered species of animals has led conservationists and advocates to lead campaign for domestication, to increase production and supply of cane rats, thus reducin...

Effects of strain, live weight and micro-environment on body weight development of cane rat (Thryonomys swinderianus) in the humid tropics

Abstract Interactive effects of strain, live weight and a non-genetic factor namely micro-environment on the live weight development of cane rats reared in captivity were investigated over a seven-month period. A total of seventy-nine (79) cane rats (Thryonomys swinderianus) originating from three different sources (strains) and of four body weight categories were used for the study. The treatment design was 4x3 Factorial of Live-weightXStrain randomly assigned to 3 Houses (block) using RCBD,...
