Document Summary
Testis develops inside and attached to dorsal wall. Epididymus isn"t wrapped around the testis like mammals. In water fowl they don"t have a penis but a better developed phallus. Know that the female in birds is heterogenetic. Evidence that the avian eggs are inherently female. How well the comb develops is a good indication of how much testosterone is being produced. Wait until they have more of maturation factors before increasing day length. Sperm head is different because of how the dna is formed and condensed. Cant freeze very well and can"t store it for very long either. When doing ai the males are usually in the same area. Take it and dilute then use it as fast as possible. Birds don"t have same distinction between parts like in mammals. The amount of time spent in each area is much faster than mammals. Sperm stored in the end of the vas deferens.
