ABSTRACT
Naghib SM, Pourjafar
M, Rowshan Ghasrodashti A, Nazifi S, Badiei K, Chalmeh A., Effect of ration bentonite and montmorillonite
on acute phase proteins in transition Holstein cows, Onl
J Vet Res., 17(9):503-507, 2013. The effect of ration bentonite and
montmorillonite on acute phase proteins induced by endotoxins in Multiparous
Holstein transition dairy cows is described. Serum haptoglobin
(Hp), amyloid A (SAA), tumor
necrosis factor-α (TNF-α) and fibrinogen (Fib) were
measured 3 weeks before and after parturition. Thirty control cows received a
balanced ration and 30 supplemented with bentonite and montmorillonite (treated
group). Compared with controls, acute phase proteins, SAA and fibrinogen
declined in treated pre- and postpartum cows. The findings suggested that
bentonite and montmorillonite may ameliorate acute phase protein response in
transition cows.
Key words: endotoxin adsorbent, acute phase
response, transition period, dairy cow.
