Studies on age related changes in serum biochemical and enzymic profile in male Surti goats

Abstract

The age related changes in biochemical profile of serum, viz. total protein, cholesterol, alkaline
phosphatase and inorganic phosphorous were studied at fortnightly interval in 21 growing male Surti goats
and were correlated with their growth rate. The experimental animals were divided equally into three
groups with 6-9, 9-12 and 12-18 months of age. The study revealed that the total cholesterol and total
protein levels increased with advancement of age, whereas the serum alkaline phosphatase (AKP) activity
was found to be decreased. The mean levels of total protein were 7.30 ± 0.06, 7.47 ± 0.09 and 8.03 ± 0.07
g/dl, total cholesterol 64.47 ± 1.53, 67.61 ± 2.24 and 70.50 ± 1.60 mg/di, AKP 266.16 ± 7.89, 232.51 ±
8.51 and 144.31 ± 8.76 IU/I, and inorganic phosphorus 13.41± 0.38, 12.08 ± 0.42 and 13.01 ± 0.47 mg/di,
in age group I, II and III respectively. The effect of age and period was significant for all the traits, but their
iriteraction was not significant. The serum inorganic phosphorous levels tended to remain static up to one
year of.age and then it declined. The serum cholesterol and total protein levels had similar trend as found
with testosterone levels in different groups of Surti bucks, but similar trend was not observed either for
serum AKP or inorganic phosphorous levels.
