Abstract

The objective of the present study was to investigate the possible genetic background of different glutathione enzyme activity in two breeds and their crosses and its correlation with age, sex and some production traits. Glutathione peroxidase activity was measured in erythrocyte haemolysate and blood plasma at one day, 4, 8 and 12 weeks and at the time of sexual maturity and in liver at day old age. The results showed that there are significant differences in the glutathione enzyme activity of erythrocyte haemolysate, blood plasma and liver among genotypes. The significant differences are not consequent at different age groups in erythrocyte haemolysate and blood plasma. Heterosis plays a role in the expression of enzyme activity. The heterosis as a percentage of the midparent values ranged from -3 to 78 for red blood cell, from 0 to 27 for blood plasma and from -12.3 to -27.6 for liver glutathione peroxidase activity and from 5.2 to 46.7 for live body weight. The high values of the reciprocal effect on the enzyme activities suggest the possibility of sex-linked and maternal effects on the enzyme activity. The phenotypic correlation between the enzyme activity and production traits depends on genotype, age and tissue.
