The differentiation of avian gonads occurred since the embryonic stage, resulted in asymmetric morphology. This study aimed to analyse the morphometric and gross anatomy of gonads in Day old Arabic chick. This study utilized 116 Day old Arabic chick. After necropsy, they were divided into 61 male and 55 female. The variables studies were length, width, volume, location, colour, and shape of the gonads. Data analysis used descriptive analysis and independent T test. The results showed a significant difference (P<0.01) between the right and left ovary lengths 1.67±0.08 mm and 3.69±0.05, respectively. A significant difference (P<0.01) between the width ovaries 0.64±0.03 mm (right ovary) and 1.18±0.03 mm (left ovary), respectively. It was found a significant difference (P<0.05) between the length of right and left testis 2.47±0.08 mm and 3.29±0.07mm, and between volume of testis 1.46±0.12 mm3 (right testis) and 2.03±0.13 mm3 (left testis). However, the right and left testes width was not significant (P>0.01). The testes colour was creamy white, sometimes pink, and grey to black, the colour of ovaries was creamy yellow and pink. Morphometric and gonadal morphology of Day old Arabic chick showed gonadal asymmetry, and the left side is larger than the right side.
