TM., Serum mineral, biochemical and hormone reference values for each trimester
and diagnosis of pregnancy in buffaloes, Onl J Vet
Res., 24 (4):224-229, 2020. Authors report reference serum calcium
(Ca+), potassium (K+), phosphorus (Po), glucose, protein
urea, cholesterol, progesterone, pregnancy associated protein (PAG), prolactin
and 17ß-estradiol
levels for 1st, 2nd and 3rd trimesters of pregnancy in
groups of 10 buffalo each. Compared with non-pregnant (n=10) controls, serum Po
was ~42% higher (P < 0.01) during 1st but 41% lower at 3rd trimester, Ca
41% higher during 2nd but 16% lower at 3rd trimesters. We
found no differences with serum K+ levels between trimesters. Cholesterol
levels were highest (~9%) at 1st and 2nd but lower (~40%) during the 3rd
trimester, glucose was 8% higher during the 1st but lower (16%)
during the 3rd. Urea increased ~8-48% from 1st to 2nd
and 3rd (~39%) and protein increased ~22-32% but only during the 1st
and 3rd with no apparent change during the 2nd. We
recorded very large differences in serum hormones finding 11 to 46 fold
increases in progesterone, 12 to 142 with PAG, 1,6 to
3.7 with prolactin but 3.2 -3.7 fold declines in 17ß-Estradiol during 2nd-3rd
trimesters with a slight elevation (24%) during the 2nd. Our findings
suggest that elevated serum PAG may be useful for diagnosing pregnancy during 1st
to 3rd trimesters in buffalo.
