The research was conducted to determine the effect of CPO (Crude Palm Oil) and Vitamin C (ascorbic acid) combination in the diet as an anti stress on broilers carcass and abdominal fat of broilers. The research was carried out in the poultry housing at UPT of Animal Science Faculty, Andalas University Padang for 42 days and 100 unsex broiler were used. The method of this research was an experiment with completely randomized design with 5 treatments and 4 replications. Replicates each consisting of 5 broilers were placed in a cage with a group size of 75 x 60 x 60cm. Results of analysis of variance showed that the combination treatment CPO and Vitamin C significantly (P<0.05) on carcass weight, but the percentage of carcass, and percentage of abdominal fat treatment have different effects and not significant (P>0.05). In this research the best trends CPO 3% and Vitamin C 500 ppm in the ration.

Probiotics are living microorganisms which controls the balance of pathogenic microbes in the digestive tract of cattle through competitive exclusion mechanism which lately has been widely used as a feed aditive both ruminants and poultry . One type of microbes used in probiotics in poultry livestock is a bacterium of the genus Bacillus . Bacillus coagulans (Lactobacillus sporogenes) had the same function as Lactobacillus sp known as probiotics were able to live in the digestive tract and produced some enzymes and antibiotics required by livestock. The method used in this study is an experimental method with a completely randomized design with 6 treatments administered dose level Basillus coagulans were repeated 5 times. Bacillus coagulans administration dose levels are : Do = Control (Provision of physiological saline without bacteria), DI = 0,6.106 CFU/ml, DII = 42.106 CFU/ml, DIII = 45.107 CFU/ml, DIV = 73.108 CFU/ml, DV = 90.1010 CFU/ml. To determine the effect of treatment used analysis of variance completely randomized design pattern and made a real difference obtained Duncan Range Test. The parameters measured were the number of colonies of Bacillus coagulans in the small intestine, feed intake, weight gain, feed conversion, and Income Over Feed Cost (IOFC) of broiler chickens. The results showed the higher dose of Bacillus coagulans were given the better growth of broiler chickens, which at doses 90.1010 CFU /ml chicken rations consume 2679 grams/head with the weight of 1810 g/fish or feed conversion of 1.48 and IOFC 170 g/kg harvest weight or Rp 508 ,-/kg harvest weight. Bacillus coagulans can be used as probiotics to aid digestion and optimal growth of broiler chickens.
