Growth Responses of Two Kenaf Varieties (Hibiscus cannabinus L.) Applied by Different Levels of Potassium, Boron and Zinc

Abstract. The trial was conducted to evaluate the effect of different levels of dried sweet orange (Citrus sinensis) peel on growth performance in broilers. A total of 400 male broiler chicks (Ross-308) were randomly allocated to treatments varying in supplemental DSOP. The dietary groups consisted of five diets fed for 42 days: control diet without feed additive, diet containing 1.5 % feed additive only in starter phase, diet containing 1.5 % feed additive during whole period (starter + grower), diet containing 3 % feed additive only in starter phase, diet containing 3 % feed additive during whole period. The growth responses achieved by broilers from all groups complied with the standards. However, adding up to 3 % DSOP in diet seems to depress feed intake, body weight gain increasing feed conversion ratio of both starter and growing broilers. Conversely, DSOP in the proportion of 1.5 % of feed seems to promote feed intake and weight gain in the period between the 1–21 days of age, indicating that DSOP can constitute a useful additive in the feeding of broilers. Further research is needed to assess the effects of DSOP to improve its suitability as a feed resource for poultry production.

Two trials with finishing lambs were conducted to study the effect of substituting wheat bran for either dehydrated alfalfa pellets or corn. In trial 1, the basal ration fed to lambs was compared by replacing dehydrated alfalfa (12.5%) with wheat bran. Growth responses to wheat bran or dehydrated alfalfa were not different (P>0.74). In trial 2, thirty-two lambs were blocked by weight and randomly assigned to four treatments consisting of the basal ration plus three different levels of wheat bran (22%, 46% and 68%) substituted for corn. The results indicated that animals on the control diet (without wheat bran) performed better (α = 0.5) than the three wheat bran diets, where the two lowest level of wheat bran diet either maintained or gained weight. Animals on the highest level of wheat bran lost weight. Gain response to the corn diet was higher (P<0.25 and P<0.003) than 22% and 46% wheat bran supplemented diets. Results also indicated that diet- A (control) and diet-C (46% wheat bran) had similar DM digestibilities, where as the diet-B (22% wheat bran) gave higher digestibilities for DM, ADF and NDF. ADF digestibility was very low in control diet (A) as compared to diet-B (22% wheat bran) and diet-C (46% wheat bran) because the control diet contained little fiber. Higher protein digestibility was observed in diet-A. Although, diet-B performed better than diet-C, Performance of diet-B was not parallel to that of diet-A and difference between diet-B and diet-C was not statistically significant (P>0.05).

We conducted experiments to decipher the interplays among bacterial motility, surface stiffness of culture medium, and growth of colony when bacteria grow on semi-solid substrate. We observed the growth kinetics of two kinds of bacteria, swarming Escherichia coli (E.coli) and gliding Myxococcus Xanthus (M.xanthus), grown on semi-solid agar substrates with different stiffness. The colony of M.xanthus moved by traction force on the surface shows a tendency to grow larger on soft substrate. The colony of E.coli using flagella shows a similar tendency in the early phase but later grows smaller on substrate with lower stiffness. We found that the growth of bacterial colony is affected by the mechanical properties of the substrate and the type of bacterial motility as well.
