ABSTRACT
The effect of monensin on the growth and rumen metabolism of young calves (30 days old initially) was followed in 70-day experiment. Calves diet consisted of a milk substitute (4 1 per day), a concentrate mixture (13 g per 1 kg of live weight per day) and meadow hay ad libitum. Ten calves were fed 0.65 mg of monensin (SPOFA, Czechoslovakia) per 1 kg of live weight per day. Ten calves served as a control. The non-glucogenic/glucogenic ratio of VFA, mol-% acetate and butyrate were significantly lower and propionate higher in monensin-treated calves. Monensin-fed calves gained non significantly more (+ 7.2%) than control calves. A possible mode of action of monensin in young calves is discussed.
