| dc.description.abstract | Reproduction and developmental process accompany dynamic changes in metabolism and oxygen consumption. Therefore the byproducts are also generated in an extraordinary scale. Among these byproducts, reactive oxygen species (ROS) are more troublesome. Normally, there exist a balance between the oxidants and antioxidant. When the balance is disrupted towards an overabundance of ROS, oxidative stress occurs. This oxidative stress leads to many problems. Antioxidants vitamins are powerful and they are helpful in prevention of many reproductive disorders like Abortion, still birth, low birth weight, pre-eclampsia, premature birth, ROS induced fetal abnormalities, endometeritis, ovarian cancers, preterm labour. Instead of their important role in reproduction there are few trials investigating the antioxidant status during the reproductive stress. Pig being an important part of meat industry, a great 2 source of animal protein and a remunerative enterprise, especially in the tribal belt of Jharkhand. The present study was conducted on 8 T & D sows to compare the antioxidant vitamins status and their correlation with reproductive parameters during different physiological stages by estimating the concentration of antioxidant vitamins, biochemical parameters and some of the reproductive performance and the same have been summarized and concluded as follows: 1. There is significant (p < 0.01) increase in blood glucose level during early pregnancy, mid pregnancy, late pregnancy even after farrowing as compared to 0 day. 2. There is significant (p < 0.01) increase in total serum protein during estrus and pregnancy as well as after farrowing. 3. The total serum cholesterol level increased significantly during estrus but goes down throughout pregnancy and even after farrowing. 4. The level of β-carotene significantly decreased slowly from estrus (22.91±0.02 μg/100 ml) to early, mid and late pregnancy as well as after farrowing (19.40±0.04 μg/100 ml). 5. Similarly vitamin C decreased from 0 day (531.31±1.66 μg/100 ml) to pregnancy and reached still lower (482.25±1.85 μg/100 ml) after farrowing. 6. However, vitamin E increased significantly from 3.51±0.04 μmol/L (0 day) to 3.87±0.03 μmol/L (estrus) but, decreased significantly in pregnancy (4.44±0.03 to 3.99±0.04 μmol/L) as well as after farrowing to 2.79±0.03 μmol/L. 7. Lipid peroxidation (LPO) of erythrocytes increased significantly in estrus, pregnancy and after farrowing as compared to 0 day. 3 8. Not a single case of abortion occurred during the present experiment, while the overall percentage of stillbirth and low birth weight were found to be 5% and 6.66% respectively in T & D sows. 9. Both stillbirth and low birth weight had negatively significant (p < 0.05) correlation with β-carotene concentration during early pregnancy. 10. Vitamin E level showed positive significant (p < 0.01) correlation during estrus with low birth weight. 11. The vitamin C concentration had negative correlation with stillbirth and low birth weight throughout the pregnancy and even after farrowing. 12. There was no valid correlation between abortion and β-carotene, vitamin E and vitamin C respectively throughout the pregnancy and even after farrowing. 13. The level of lipid peroxidation of erythrocytes showed negatively significant (p < 0.01) correlation with β-carotene and vitamin C. Whereas, the level of lipid peroxidation of erythrocytes showed positive significant (p < 0.05) correlation with blood glucose. | en_US |
