Photomicrograph of the testes of bucks Damascus goats fed mixtures plant herbs (PHM) or Quebracho tannins-supplemented diets (QT).
[A]: Histologic section of the testis of bucks in control group showing the damage of seminiferous tubules, desquamated epithelial cells in the lumen of seminiferous tubulles, haemorrhage and edema of interstitial tissue (blue arrow), vacuolation of spermatogenic epithelium of seminiferous tubules (black arrow), desquamated necrotic spermatogenic epithelium in seminifferous tubules (red arrow), thickening of interstitial tissue surrounding seminiferous tubules (yellow arrow) (H&E ×10).
[B]: Histologic section of the testis of bucks in group CTS testis, showing somewhat normal histology of testis (red arrow) with slight degeneration and edema (blue arrow) (H&E ×10).
[C]: Histologic section of the testis of bucks in group PHM testis, showing clearly defined, intact seminiferous tubules and normal spermatogenesis (black arrow) (H&E ×10).
