The poultry industry in subtropical climates faces the challenges of climate and variable feed quality, in addition to those challenges encountered in temperate zones. These challenges aggravate the problem associated with the progressive decline in reproductive performance due to genetic selection for growth and yield traits. Heat stress is the major cause of lower fertility in both males and females, regardless of age. Under such situations, nongenetic factors play critical roles in… CONTINUE READING
