abstract
The present study was undertaken to find out the association of different blood parameters viz., Calcium, phosphorus, haemoglobin and total serum protein with different physiological parameters viz., age, sex, pregnant, non-pregnant and types of kidding. The experiment was conducted on Black Bengal goats for a period of one year at Doloipur village, Nadia district of West Bengal in the month of January, 2011 to January, 2012. It was observed that the calcium level varies significantly (P>0.05) between age group of Black Bengal goat. The range of calcium level decreased with increase in age. Male animal shows higher level of calcium, phosphorus, haemoglobin and total serum protein than the female animal in all the age group. It was observed that the level of phosphorus decrease with age except in 0-3 and 3-6 months of age group, which shows increased level and the total serum protein increases with advancing age except 6-9 and 9-12 months of age. The level of haemoglobin increases with the advancing of age. It was also observed that the Calcium, phosphorus, total serum protein and haemoglobin level was higher in non-pregnant animal as compared to pregnant animal. At different type of birth it was observed that the level of calcium, phosphorus, haemoglobin and total serum protein increase in single born than the other type of birth. For all the blood parameters in different age group, triplets kidding shows lower level than single and twin kidding.
