Kombinasi Vitamin E Dan Bakteri Asam Laktat (Bal) Terhadap Konsentrasi Bal Dan Potensial Hidrogen (Ph) Pada Ayam Kedu Dipelihara Secara in Situ

The study aims to determine the effect of the addition of lactic acid bacteria in the ration to potential hydrogen (pH) and the concentration of lactic acid bacteria (LAB) in digestive track 12 months old kedu chicken. The research was conducted on November 2011 to January 2012 on Livestock Farmers Groups Makukuhan Mandiri Kedu, Temanggung. The Research using 100 female kedu chickens, and 20 male kedu chickens age of 12 months. Experimental design used was Completely Randomized Design (CRD) with 4 treatments and 5 replications (5 females and 1 male). Treatment applied is T0 = ration without supplements, T1 = ration + 20 IU vitamin E, T2 = ration + 0.6 ml lactic acid bacteria (Biostarter A) and T3 = ration + vitamin E 20 IU + 0.6 ml acid bacteria lactate (Biostarter A). Ration composed from bran, yellow corn, soybean meal, fish meal, shellfish meal, and CaCO3. Parameters observed include consumption, LAB concentrations, intestinal pH conditions, rate of digesta, and hen day production. The results showed that the concentration of lactic acid bacteria (LAB) (P <0.05) is significant among all treatments but the combination of vitamin E and LAB lower the pH and slow the rate of digesta. Other parameters such as consumption and hen day production (HDP) is not affected by the treatment. Conclusion from the study is addition of vitamin E by 20 IU/100 g ration and lactic acid bacteria as much as 0.6 ml / head / day make the same result in consumption of rations and daily egg production, but may increase the concentration of lactic acid bacteria, lowering the pH of the small intestine, and slow the rate of digesta
