Abstract:
There were scanty studies on the interaction between cholesterol and testosterone and far scantier studies on this topic in indigenous bovine. Hence the present study was aimed to know the interplay of cholesterol and testosterone with regards to the age of the breeding bulls. Twelve breeding bulls of the Livestock Research Station, Lam, Guntur, Andhra Pradesh were grouped into two different age groups (n = 6) each viz., young breeding bulls and adult breeding bulls. Serum cholesterol and Serum testosterone were estimated in all the bulls. The effect of age on serum cholesterol and serum testosterone and their mutual interaction was studied. Serum Total protein was also estimated in both the groups to see the difference in feeding status of the bulls, if any. Significantly higher values (P<0.05) were observed in serum testosterone in adult breeding bulls compared to young ones. On contrary, significantly lower values (P<0.05) were noticed in serum total cholesterol in adults compared to young breeding bulls. The serum total protein in both the groups were significantly similar.
