Abstract/ Executive Summary:

Duck has great prospects for sustainable development of the economy of the poultry industries in Bangladesh. The current research was designed to investigate the histological changes of testes of Khaki Campbell ducklings. The study was conducted in the Department of Anatomy & Histology, Bangladesh Agricultural University, Mymensingh. The experimental Khaki Campbell ducks (Anas Platyrhynchos Domesticus) were collected from poultry farm of Bangladesh Agricultural University, Mymensingh, having apparently good health and devoid of any external deformities. The ducklings were from three age groups (Total 15 ducklings): day one (1), one (1) month and three (3) months, having five ducklings in each group. The testes were collected immediately after ethical killing of the birds for histological observations. The collected tissue samples were then processed and stained with Hematoxylene& Eosin (H & E) stain for histological observations. The histological observations revealed that at day 1 and 1 month old, spermatogonia and sertoli cells were present within the tubiform shaped seminiferous tubules. Slightly distinct seminiferous tubules were observed at 3 months of age which contained spermatocytes along with spermatogonia. The present study indicates that development of seminiferous tubules up to 3 month is age related which was similar to that in other avian species. This study first time described the developmental features of testicular cells/tissues of Khaki Campbell duckling in Bangladesh.

Program Area: Animal Health and Management

Commodity: Duck

Objectives:

1. Investigation on the developmental features of testicular cells/tissues of Khaki Campbell duckling in Bangladesh.

2. Comparing the developmental features of testicular cells/tissues of Khaki Campbell duckling with other avian species.

Methodology:

A total of 15 male Khaki Campbell ducklings of day 1, 1 month and 3 months ages were used in the present study. After taking live body weight, birds were killed ethically. Tissue pieces were collected from different regions of the testis and subsequently fixed in 10% formalin solution. All the tissues were processed for paraffin sections by alcohol-xylene method. Sections were cut at 5 µm thickness using a Rotary Microtome and stained with Haematoxylin and Eosin stain. The details histological study was completed using a high power light microscopy. The measurements of the thickness of the tunica albuginea, diameter of the seminiferous tubule were done by using ocular micrometer.

Achievement/Findings:

The results of the present study revealed that at day 1 and 1 month old, spermatogonia and sertoli cells were present within the seminiferous tubules and spermatocytes along with spermatogonia were present at 3 months of age. Other testicular cells like spermatid and spermatozoa were not observed within the testis of the ducklings of experimental ages indicating that the testicular development occurs slowly in Khaki Campbell duckling. The results of our studies also pointed out that the structure of testes of Khaki Campbell ducklings was similar to that in other avian species. This study described the developmental features of testicular cells of Khaki Campbell ducklings which may provide some valuable information to the researcher, students and autonomous learner.
