Abstract

The purpose of present study was to collect informations on the possible genetic background of glutathione peroxidase enzyme activity in different genotypes, age and sex of chicken, and its correlation with some production traits. Blood samples were collected from six genotypes: Plymouth, Naked Neck Plymouth, Naked Neck New Hampshire, Hungarian Speckled, Transylvanian Naked Neck White, and Hungarian White, aged one-day, 4 wks, 8 wks, 12 wks, at the period of sexual maturity and at the age of the highest egg production. Glutathione peroxidase activity was measured in blood plasma and erythrocyte haemolysate. The enzyme activity in the liver was also measured at day-old age. The results showed that there were significant differences in the glutathione peroxidase activity of blood plasma and erythrocyte haemolysate among genotypes in all age groups. The significant differences were not consequent at different age groups. There were also some significant differences in the enzyme activity of liver among different genotypes. Sex also has a significant effect on red blood cell and blood plasma glutathione peroxidase enzyme activity. Negative correlations were found between glutathione peroxidase activity of blood plasma, erythrocyte haemolysate and liver at day-old age and body weight. Negative correlation was found between GSHPx activity of liver and red blood cells and egg production and significant positive correlation between GSHPx activity in blood plasma and egg production.
