Susceptibility to peroxidation and fatty acid composition of fresh boar semen obtained from different hog farms
Objectives of this study were to determine the fatty acid composition and to analyze the sensitivity to lipid peroxidation of different boar fresh semen samples from two herds, H1 and H2. Lipid peroxidation was evaluated using chemiluminescence (cpm/mg of protein) and fatty acid profile by means of...

The great amounts of polyunsaturated fatty acids found in H2 samples could be related to the loss of acrosomal integrity. Our results indicate that boar semen contains great amounts of polyunsaturated fatty acid in its composition, which were vulnerable to the lipid peroxidation.
