abstract
Significantly higher total serum protein was found in T &D x Tamworth and T &D x Russian Charmukha followed by T &D x Hampshire and T &D x T &D where former two genetic groups did not differ significantly but later two groups differ significantly from each other. Significantly higher hemoglobin (13.98%) was estimated in T &D x Tamworth as compared to T&D x T&D (12.92%), T&D x Hampshire (12.76%) and T&D x Russian Charmukha (12.71%); the differences among latter three genetic groups were non-significant statistically. The genetic groups had non- significant effect on serum cholesterol level and total erythrocyte count. Understanding the above fact about blood parameters will further help in formulating breeding strategies for pig improvement
