The morphometric study of testes of Turkey Tom

Abstract

The goal of the study was to determine the actual location of testes and morphometric study of turkey tom testes. Fifteen turkey toms were collected from a turkey farm of different age variation then divided into three groups and reared in the poultry research shed under the Dep. of Dairy and Poultry Science. Then sacrificed the toms and determined the location of testes at age variation and collected the samples for morphometric study at the Anatomy and Histology laboratory under the Dep. of Anatomy and Histology in Chattogram Veterinary and Animal Sciences University. Then the length, width, thickness and weight of the testes were measured. For microscopic study permanent slides were prepared. The testes were located in abdominal cavity caudal to the respective lung on the either side of midline. The testes were oval in shape in all ages. The color of testes were varied according to age, during immature stage they were yellowish and became white gradually when became mature. Microscopically the spermatogenic cells were round and nuclei were dark-round in group-I and group-II. The spermatogenic cells were columnar and nuclei were oval in group-III. No spermatozoa were present in group-I and in group-II and group-III spermatozoa were present. Through the knowing, the actual location of testes the turkey farmers can easily collect semen from turkey tom by the palpation or message method. Then the turkey farmers can artificially inseminate (AI) to the turkey hen which increases the fertility and hatchability of egg. The turkey farmers also can caponize the turkey toms through the knowing of testes location.
