An ethanolic extract of chamomile was obtained with the concentration of 111 mg/ml. Calves were randomly divided into four groups, each receiving one of four chamomile treatments; 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 in concentration of serum IgG between LC and CO calves (P = 0.792). MC calves had a significantly higher serum IgG concentration at 48 h compared with 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). These results show that chamomile extract could promote colostral IgG absorption in neonatal calves if a suitable dose is given immediately after birth. https://ijvm.ut.ac.ir/article_23844_0dce9a4c1ae247db0d885b4950b0e0f6.pdf
