Note on the use of berberine tannate (Bertamix ND ) for increasing the productivity of meat yielding in pig breeding in Vietnam

Abstract

The author presents the results of a study on the effect on indigenous pigs of berberine tannate (bertamix), a growth promotor extracted from Cossinium fenestratum (Gaertn) Colebr. and trunck bark of Terminalia chebula Retz which are available in large amount in Vietnam. The addition of Bertamix^ND at the rate of 5 p. 1000 in the diet for the pigs aged 3-5 months improves the weight gain by 21 % and feed conversion by 17,3 % with a reduction of 0.76 forage unit/kg of weight increase. The interest of use Bertamix^ND as a growth promotor for meat pigs in Vietnam is discussed.
