Influence of parenteral administration of chamomile (MatricariarecutitaL.) extract on colostral IgG absorption in neonatal calves

In this study, the effect of chamomile extract on the ability of neonatal calves to absorb immunoglobulin G (IgG) was evaluated.An ethanolic extractof chamomile was obtained with the concentration of 111 mg/ml. Calves were randomly divided into four groups, each receiving one of four chamomiletreatments; 1: low dose (LC; 5.5 mg/kg body weight; 2: moderate dose (MC; 11 mg/kg); 3: high dose (HC; 22 mg/kg); 4: a control (CO; normal saline).Chamomile extract was injected intravenously into the jugular vein 1 h after birth and before colostrum intake. There was no significant difference inconcentration of serum IgG between LC and CO calves (P = 0.792). MC calves had a significantly higher serum IgG concentration at 48 h comparedwith LC and CO calves (P = 0.002, P = 0.003, respectively). There was no statistical difference between MC and HC calves at 48 h (P = 0.264). Theseresults show that chamomile extract could promote colostral IgG absorption in neonatal calves if a suitable dose is given immediately after birth.
