Effect of efrotomycin (MK-621) on gain and feed efficiency in growing and finishing pigs


, : Effect of efrotomycin (MK-621) on gain and feed efficiency in growing and finishing pigs. Anais do IV Congresso Brasileiro de Veterinarios Especialistas em Suinos, Itapema SC 1989: 58

In a random block experiment with 4 treatments and 4 replicates 64 Landrace X Large white pigs, initially 55 to 58 days old, were given diets based on maize and soyabeans without or with efrotomycin, a new antibiotic produced by Streptomyces lactamdurans, 2, 4 or 8 mg/kg for 104 days. No adverse reactions to the antibiotic were observed. Efrotomycin improved gain and feed efficiency during the first 84 days, especially in the early stages.
