Effects of Dietary Crude Glycerin Concentration on Testicular Morphology and Oxidative Stress Markers and on Plasma Testosterone Concentrations

Summary We evaluated the effects of feeding 6%, 12% or 18% crude glycerin, containing 80.5% glycerol, on testicular histomorphometry and markers of oxidative stress and on plasma testosterone concentrations in lambs. Body weight, testicular biometric measurements, gonadosomatic index and net weight of the testicles were higher for the treated groups (P
