Extract

Avotan is a feed additive commonly used in finishing and growing beef cattle systems to improve feed efficiency - producing higher liveweight gains on similar feed intakes. The active ingredient is a glycopeptide antibiotic (Avoparcin, Cyanamid UK) active against Gram - positive bacteria. In 1991 Avotan received an EEC product licence for use in dairy cows. Extensive trials showed that on average Avotan gave a 5% response in milk yield on the same level of feed intake with no effect on milk composition. No information was however available on the use of Avotan in beef cows. This trial reports on the response of autumn calving suckler cows to Avotan in terms of both cow and calf liveweight change and cow fertility.
