Rearing system influences the testicular development, semen quality and spermatogenic cell apoptosis of layer roosters

26 Mar 2021

Abstract excerpt

The objective of this study was to compare the testicular development, semen quality, and spermatogenic cell apoptosis of roosters reared in colony, single, and large cages. Rohman parental layers (n = 540) were randomly allocated into cages of rearing system groups (135 males and 405 females). The experimental period was 70 to 210 d of age. We compared testicular development and plasma main reproductive hormones...
