National audienceFemales of three genotypes NaNa (naked neck homozygotes), Nana+ (naked neck heterozygotes) and na+na+ (normal plumage), hatched from the same parents, were distributed in two treatment groups : control (kept at moderate temperature with fluctuations according to climatic variations) and heated (constant 31°C from 4 to 39 weeks of age). In the control group, average weights of the three genotypes differed little at 10 weeks of age, but after that age the body weight gain was considerably inferior for the NaNa genotype compared to na+na+, and consequently body weights at 18, 27 and 39 weeks of age were lower for naked neck homozygotes, and accordingly their mean shank length was slightly inferior. On the contrary, wattle leng...
