[Prevention of ruminal acidosis during the intensive fattening of weanling lambs].

Forty-eight intensely fattened weaned lambs, divided into 2 groups were used to test the prophylactic effect of lasalocid with regard to rumen acidosis. The animals were offered complete mixtures ad libitum, containing 80 per cent concentrates and 20 per cent cut meadow hay. The weaned lambs of the test group were given the preparation "Avatek' (with 15 per cent lasalocid) in the course of 60 days with the feed at the rate of 250 g per ton of the complete mixture.
