Vitamin A is one of the most important fat-soluble vitamins. Because of its particular role in differ-
ent tissues and organs, in deficiency conditions various clinical signs are seen. In addition sometimes
the marginal deficiency is present and clinical signs are not visible but performance defects such as
infertility is seen.
In some regions of Iran, buffalo is breading for production of milk and meat. In large animal, much
study about beta-carotene and vitamin A is done in cow and information about buffalo is little. In
present study, seasonal changes of vitamin A and beta-carotene in serum and liver of 120 buffaloes
was investigated in Ahvaz slaughterhouse (Iran), between May 1998-April 1999. We, also, selected
animals from 2 sexes and divided them to the 5 age groups ( less than 2 , 2-3 , 3-4, 4-5 and more than
5 yrs old).
Spectrophotometery was used for measuring vitamin A and beta-carotene. The results were analyzed
statistically with multifactorial repeated measures ( ANOVA) and Pearson's correlations. Results
showed that the values of mean of serum and liver vitamin A and serum and liver beta-carotene.
(69.01 ± 2.23 µg/dl, 111.99 ± 6.42 µg/gr 21.43 ± 2.21 µg/dl, 23.19 ± 2.23 µg/gr respectively) are sim-
ilar to normal ranges in cows. These values in different seasons, age groups and 2 sexes were nor-
There wasn't significant difference between vitamin A and beta- carotene values of the serum and liv-
ers for both the 2 sexes and age groups.
We couldn't find any similar study about the effect of sex and age groups on vitamin A and beta-
carotene content in Buffalo. Rather, these findings are not in accordance with the results of previous
studies in cow.
However, the was significant seasonal variations in serum vitamin A ( max in autumn and min in
spring) and liver vitamin A ( max in spring and min in winter). The difference between seasons serum
vitamin A is similar to those reported in similar studies performed in Yugoslavia. There wasn't sig-
nificant difference between different seasons serum and liver beta carotene .
