Ejaculate characteristics of three genotypes of local cocks in the humid tropics

Twenty four (24) adult Nigerian local cocks comprising 8 naked-neck, 8 frizzle and 8 normal were subjected to two ejaculations per week for 14 weeks using the massage technique. Ejaculates were subjected to both physical and chemical evaluations. Results showed that naked- neck and frizzle cocks had higher (P0.05) among the three genotypes. There were also no significant differences in most of the chemical parameters among the genotypes. From these results the naked-neck and frizzle cocks appear superior to normal cocks under the humid tropical environment in semen output and quality..
