The effects of level of dried distillers grains with solubles (DDGS) and rice polishings (RP) on the scrotal circumference and semen parameters were examined in 22 crossbred (Pelibuey x Dorper) ram lambs (average live weight 24.84 ± 2.07 kg, approx. 5 months of age). The lambs were randomly allotted to four treatments in a 2 x 2 factorial design. The two factors were dietary levels of RP (0 and 15%) and of DDGS (0 and 30%). The experiment lasted 52 days. The animals were weighed on days 0, 34 and 52, and semen variables were measured on days 34 and 52. Semen evaluation included sperm morphology, mass and progressive motility, and sperm concentration. On day 34, sperm concentration showed an interaction of both effects (P=0.01) and was greater in rams in group 4 (both RP and DDGS) than in those in groups T2 (RP alone) or T3 (DDGS alone). Sperm morphology (% normal cells) was higher (main treatment effect) in rams fed with 30% DDGS than in those not fed with DDGS (P |
