Organ reproduksi utama pada sistem reproduksi kalkun jantan adalah testis yang mempunyai sel Leydig pada jaringan interstitial-nya. Sel Leydig berperan penting dalam spermatogenesis dan steroidogenesis. Penelitian ini bertujuan untuk mengetahui perkembangan dan jumlah sel Leydig pada testis kalkun (Meleagris gallopavo) berdasarkan tingkatan umur yang berbeda. Sampel penelitian dibagi menjadi lima kelompok umur (8, 16, 24, 32 dan 40 minggu) dan masing-masing kelompok berjumlah empat testis kalkun. Testis kemudian diproses hingga menjadi sediaan histologi dengan ketebalan ±3 µm, selanjutnya diwarnai menggunakan pewarnaan Haematoksilin-Eosin (HE). Hasil penelitian menunjukkan bahwa ukuran sel leydig testis kalkun pada kelompok 8, 16 dan 24 minggu menunjukkan perbedaan nyata (P

The main reproductive organ in the male turkey reproductive system is the testis, which has Leydig cells in its interstitial tissue. Leydig cells play an important role in spermatogenesis and steroidogenesis. This study aims to determine the development and number of Leydig cells in turkey (Meleagris gallopavo) testes based on different age levels. The research sample was divided into five age groups (8, 16, 24, 32 and 40 weeks) and each group amounted to four turkey testes. The testes were then processed into histology preparations with a thickness of ±3 µm, then stained using Haematoxylin-Eosin (HE) staining. The results showed that the size of leydig cells of turkey testes in groups of 8, 16 and 24 weeks showed a significant difference (P < 0.05) while in groups of 32 weeks and 40 weeks there was no significant difference. In the number of Leydig cells, there was a significant difference (P
