FERTILITY OF BROILER MALES AND FEMALES AT VARIOUS AGES BY USING ARTIFICIAL INSEMINATION

Abstract

The study was conducted to determine the effects of the age of male and female and the interaction between them on fertility of broiler breeder flock , using Hubbard flex flock which consists of ( 12 ) males and ( 40 ) females at 44-47 weeks of age( mature birds ) and same numbers at 65-68 weeks of age( aged birds ) .Artificial insemination were used in mating within same age group and between various age groups using 0.05 ml. of undiluted semen or 0.1 ml. diluted semen with Lake diluent . pooled semen were used for each age and 1:2 dilution rate . Eggs were collected during the period 2-8 days after insemination and set in the incubator for seven days before broken to examine the embryonic development and determination fertility of various treatments ,Results indicated that there were no significant differences in fertility among age groups included in the experiment , while there were significant interaction effect between male × female ages on fertility . There were no significant differences in fertility between diluted and undiluted semen .
