An experiment, with a split plot experimental design, was conducted to determine the effect of feeding system (full vs choice feeding) and fermented sago waste (AST 5 vs 0%) on the performance of broiler chickens. Complete feed was formulated tocontain 21% crude protein, 2900 kcal ME/kg, without or with 5% AST. Feed for choice feeding was formulated to contain 2900 kcal ME/kg, without or with 5% AST with crude protein 23 or 17%. Four hundreds DOC broilers were used for each treatment divided into 4 replicates (100 birds/replicate) on litter system. Feed and water were given ad lib. during the 4 weeks trial. Data collected included feed consumption (weekly), body weight (bi-weekly), feed conversion ratio (FCR) and protein efficiency ratio (PER) were calculated biweekly. Feeding system has no significant effect on total feed/energy consumption. Choice feeding reduced total protein consumption (P<0.01; 323.5 vs 354.9 gram/head/4weeks), increased body weight gained (P<0.01; 889.5 vs 835 gram/head/4weeks), improved FCR (P<0.05; 1.90 vs 2.03), and PER (P<0.001; 0.37 vs 0.43). Fermented sago waste (AST) had no significant effect on total feed/energy consumption (P<0.05), reduced total protein consumption (P<0.05; 333.6 vs 349.8 gram/head/4weeks), increased body weight gained (P<0.05; 887.5 vs 837 gram/head/4weeks), improved FCR (P<0.05; 1.88 vs 2.06) and PER (P<0.05; 0.38 vs 0.42). It is concluded that broiler chicken had an ability to determine its protein requirement, and AST supplementation significantly improved performance of the birds.

An experiment had been conducted to evaluate the effect of marine yeast and Saccharomyces cerevisiae (Sc) as probiotic supplement on poultry performance. Marine yeast isolated from rotten sea-weed and commercial Saccharomyces cerevisiae were used. Evaluation was conducted by comparing performance of broiler chicken supplemented with marine yeast or Sc, which were given through drinking water (5 ml/l) to negative control (feed without antibiotic growth promotor/GPA), positive control (feed with GPA), and reference commercial probiotic. Forty DOC broiler birds were used for each treatment, divided into 4 replicates (10 birds/replicate) and raised in wire cages for 5 weeks. Body weight and feed consumption were measured weekly and mortality was recorded during the trial. The results showed that there were no significant difference on the birds performance among marine yeast, Sc, positive control and probiotic reference control treatments. However their effects on bird performance were better (P<0.05) than treatment of negative control. It is concluded that marine yeast or Saccharomyces cerevisiae could replace the function of antibiotic as a growth promotant.

produced, and suitable with the environment of the digestive track. Isolation was carried out from commercial culture (containing mixture of Bacillus spp.), digestive tract (proventriculus, small intestine and large intestine) of local and broiler chickens, and commercial yoghurts (fermented milk). Neutral and acidic nutrient agars (NA) were used as the media at room temperature and in the aerobic or anaerobic conditions. Separate colonies were isolated, stained with Gram and spore staining and observed under the microscope. The bacteria which were Gram positive bacillus and can form spores were further identified. Eight different species of Bacillus spp.: B. laterosporus, B. coagulans, B. alvei, B. circulans, B. brevis B. bodius, B. pasteurii, and B. macroides were isolated from the commercial mixture. From the digestive tracts of local and broiler chickens, 13 bacteria and 2 yeasts were isolated, while 5 yeast were obtained from two commercial yoghurts. Those bacteria were facultative aerobic and only grew in neutral condition and not in acidic condition (pH 4.5), while the yeast were either facultative anaerobic also can grow in pH neutral and 4.5. The ability of each isolates to grow in the media containing mixture of minerals and glucose, sucrose or molasses were evaluated. Incubation was carried out in the shaker incubator at 40Â°C, 150 rpm for 48 hours. Dry matter of the biomass was determined as the growth parameter. All isolates of bacteria and yeast can grow in the substrate containing glucose, sucrose and molasses. Variance analyses show that there were interactions between kind of bacteria and carbon source or between kind of yeast and carbon source (P<0.05). Three isolates of bacteria that had highest production of biomass were B. coagulans on sucrose (the third for molasses), Sp. 9 on glucose, and B. apiarius on sucrose (the sixth on molasses). B. apiarius isolated from digestive tract of local chicken will be useful to be developed as probiotics. The highest production of yeast was the control Saccharomyces cerevisiae on three sugars. Between the isolates from digestive tract of local chicken, Toluraspora delbrueckii AL-15 produced 13.8x10-1mg/ml biomassa on molasses.

A series of chemical, biological assay and growth trials were conducted to determine the nutritive value of hominy, relative to corn. The crude protein, ash, NDF and ADF content of hominy were 10.25%, 2.10%, 19.10% and 4.70% respectively, and are higher than the corn level, 8.5%, 0.40%, 2.30% and 1.90% respectively. While its crude fat (3.20%) and metabolize energy (3,020 kcal/kg) contents were lower than the corn level 4,40% and 330 kcal/kg. Seven hundred DOC broilers of commercial strain were used for growth trial for 42 days. The birds were divided into 5 treatments group with 4 replications (35 bird/replicate). Experimental rations, starter and finisher, were formulated with graded levels of hominy on the expense of corn (A = 0%, B = 33.3%, C = 50%, D= 66.6% and E = 100%) with similar level of crude protein and metabolize energy. Feed consumption was not affected (P>0.05) by the treatments, however body weight gain (BWG) and feed conversion ratio (FCR) were both significantly (P<0.05) affected by the treatments. Body weight gain of treatment A (1,712 g) was similar to treatment B (1,683 g) and C (1,682 g) but significantly (P<0.05) higher than treatment D (1,598 g) and E (1,570 g). Feed convertion ratio of treatment A (2.17) was similar to the treatment B (2.26) but significantly better (P<0.05) than treatment C (2.30), D (2.36) and E (2.39). Carcass quality was not affected by the treatments except for the shank color, where treatment A (7.38) was significantly yellower than the other treatments (B=2.50, C=2.75, D=1.75 and E=1.0). It is concluded that the protein content of hominy is higher than corn, but its metabolize energy was lower than the corn. Hominy could be included in the ration replacing corn up to 33.3% without affecting performance of the bird. Â Key words : Poultry, hominy, nutrient
