Three experiments were conducted to examine: (a) the apparent metabolisable energy (AME) contents, the level of non-starch polysaccharides (NSP), and the extract viscosity value of 9 wheat samples; (b) the efficacy of a xylanase in reducing between-bird variation for AME; and (c) the effect of a xylanase on the number of Clostridium perfringens in broilers fed a low AME wheat diet. Experiment 1 revealed that the AME value of wheat varied from 11.5 to 13.6 MJ/kg dry matter (DM), which negatively correlated with the total NSP level (r = –0.97). Experiment 2 involved a 48-cage individual bird trial, where xylanase increased (P < 0.05) the AME from 12.51 to 13.09 MJ/kg DM and reduced (P < 0.05) its standard deviation from 1.13 to 0.52. The standard deviation for feed conversion ratio, ileal viscosity, and faecal viscosity was also reduced. In this experiment, there was a strong correlation between AME and excreta viscosity (r = –0.81) and the caecal xylanase activity of birds fed the control diet was positively correlated with AME (r = 0.72). In Expt 3, xylanase reduced the number of Clostridium perfringens, the causative agent for necrotic enteritis, to a non-detectable level in the ileum and caeca of broilers fed a low-ME wheat diet.

This study aims to examine the effect of giving a solution of binahong leaves (Anredera cordifolia) in drinking water on the physical quality of broiler chicken meat finisher phase. A total of 72 broiler chickens strain CP 707 produced by PT Charoen Phokphan Indonesia. This study used a completely randomized design (CRD) with 4 treatments and 6 replications. The treatments consisted of R0: drinking water without binahong leaf solution, R1: drinking water + 20 ml of binahong leaf solution/liter of water, R2: drinking water + 30 ml of binahong leaf solution/liter of water, R3: drinking water + 40 ml of binahong leaf solution / liter of water. The results of analysis of variance and Kruskal wallis showed that the treatment had no significant effect (P>0.05) on meat pH, water holding capacity, tenderness, and cooking loss of broiler chicken. Based on the results of this study, it can be concluded that the addition of binahong leaf solution with a level of 20 mL/liter of water, 30 ml/liter of water, 40 ml/liter of water has not had and effect on the physical quality of the finisher phase broiler chicken meat.

The purpose of the research was to determine the Effect of purslane flour in the ration on the meat chemical composition of broiler chicken. 100-day old chicks broiler used in the experiment, and the study used a completely randomized design (CRD) with four treatments and 5 replicates. The four treatments were: (1) T0: commercial ration; (2) T1: commercial ration + 2.5% purslane flour; (3) T2: commercial ration + 5% purslane flour; and (4) T3: commercial ration + 7.5% purslane flour. Parameter measured were water, protein, and fat content of broiler meat. Data obtained by cutting 60 chickens from which 15 chicken from each treatment. Statistical analysis showed that the addition of purslane flour in ration did not have significant Effect (P > 0.05) on water content, but had very significant Effect (P < 0.01) on protein and fat content of broiler chicken meat. It can be concluded that purslane flour added to basal ration up to 7.5% of broiler chickens could improve the quality of broiler’s meat.
