Abstract

An experiment was conducted to determine the effects on growth performance and health status of Tam Hoang chickens (n=720) of adding to the diet two organic acid products (Menacid  and  Poulacid) given separately, or as a mixture. The experiment was conducted for 12 weeks with 6 treatments in a 6*2 factorial design and 3 replications. The first factor was organic acid supplement; the second factor was gender (male or female). The treatments were: Cont: Basal diet (BD) without any organic acid product; M0.8: BD with 0.8g Menacid/kg feed; M1.0: BD with 1.0gMenacid/kg feed; P1.0: BD with 1g Poulacid acid/kg feed; P1.5: BD with 1.5g poulacid/kg feed; MP: BD with 0.5g Menacid and 1g Poulacid acid/kg feed. Results showed that average daily gain (ADG) of chickens overall 1 to 12 weeks fed M0.8 and MP were better than the control, average feed intake (ADFI) did not differ among the treatments. Feed conversion (FCR) over the 12 week period was better for the M0.8 treatment compared with the control but the other treatments did not differ from the control. Lactobacilli and Salmonella.spp were not detected in chicken feces neither at 42 nor 70 days of age. Clostridium perfringens and E. coli were reduced in all suplemented treatments, so morbidity (13-19%) and mortality (10-15%) were high. It is concluded that there was an apparent improvement in growth rate (8%), linked with a reduction in pathogenic bacteria (E.coli and Clostridium perfringens) in the feces when chickens were supplemented with a commercial source of organic acids.Key words: Clostridium perfringens, E.coli, Lactobacillus, organic acid,  Salmonella.spp, Tam Hoang
