Cemani chicken: characteristics of fresh semen, testes morphometric, and the relationship between the two traits

Abstract

The monitoring of the reproductive performance of roosters can be conducted by examining the characteristics of fresh semen, the morphometric approach of the testes, and the correlation between these two traits. To analyze the semen traits, a total of ten rooster heads were utilized, while the morphometric analysis of the testes was performed on five rooster heads. Descriptive methods were employed to assess the shape and characteristics of the fresh semen. The average length, width, weight, and circumference of the testes were evaluated using a T-test with a confidence level of 95%. Furthermore, Pearson’s correlation was employed to investigate the association between the traits of the semen and the morphology of the testes. The effects confirmed that the testes of Cemani chickens had been no extraordinary from chickens in general, placed inside the frame hollow space close to the spine, connected to the dorsal belly hollow space, or simply in the back of the lungs and the front of the kidneys and testes, elongated and oval. Typically, the left testes were relatively longer, wider, and heavier than the right testes. The semen exhibited a creamy white color, with a thick consistency and an acidity level of seven. Furthermore, it displayed a satisfactory mass movement with an average value of 2.80 ± 0.92. The motility and viability of the spermatozoa were within the normal range (70.50 ± 5.50 and 80.90 ± 4.58, respectively) at a concentration of 1402 ± 382 x 106/ml. The characteristics of the semen and the size of the testes (both left and right) demonstrated a correlation with motility. This observation concluded was that Cemani chickens exhibit remarkably accurate semen characteristics and testicular morphometrics.
