Histological changes in the testes of male Awassi sheep fed a diet containing spirulina platensis

Abstract

Effect of feeding spirulina platensis (Sp. Platensis) in the diets of male Awassi sheep on some histological characteristics of the testicles, using 12 males distributed into three groups (4 males/group) distributed randomly, the feed was provided without additives to the first group and was considered a control group  (T1), while the 2^nd group (T2) was given concentrated feed with the addition of (80 g/kg) of concentrated feed, while the 3^rd group (T3) was fed concentrated feed with the addition of 120 g/kg of concentrated feed. In order to achieve the benefit of adding Sp. platensis to the feed, histological sections of the testicles were studied after slaughtering the animals. The results showed, that feeding with Sp. platensis showed significant differences between the control group and the other two groups. Necrosis was observed in and the deposition of amyloid fluids with damage to the STs in the two treatment groups compared to the control, with the occurrence of degeneration of the interstitial tissue as well as the tunica propria. This may explain that feeding with Sp. platensis at these rates under study has It results in potential damage to the testicular tissue. To gain more knowledge, this aspect must be studied and more experiments must be conducted at different ages on male sheep.
