  This study was conducted to investigate the effect of Solid State Fermented Feed (SSFF) with and Without Prepared Probiotic (PP) on the live body weight, weight gain, feed intake and feed conversion ratio of a local Malaysian chicken (Akar Putra). A total of 96 day-old Akar Putra chicks, were randomly assigned to four dietary treatments (24 chicken/treatment), with 3 replicates for each (8 chicken/replicate). The four dietary treatments were the control T1 (no supplement), diet supplemented of SSFF with probiotic in the second treatment was prepared at the rate 1:1:1 (1 kg of commercial broiler feed+1 L tap water+1g PP). While the rate was 1:1:2 (1 kg of commercial broiler feed+1 L tap water+2 g PP) in the third treatment. The chickens in fourth treatment were fed on SSFF without probiotic. The feeding mixtures of T2, T3 and T4 were placed in a plastic tray which closed ad incubate for 38 h at 37±2°C for complete fermentation and used without drying. Supplementation the SSFF with PP resulted in a significant (p<0.01) increase in the males' and females'live body weight. Furthermore, (p<0.01) enhancement in the females' feed conversion ratio of supplemented treatments was observed. It can be concluded that using wet fermented feed with 1 and 2 g of prepared probiotic caused significant improvement in the production performance of Akar Putra chicken especially in the live body weight and growth rate traits.

  In an experiment with 120 Akar Putra chicken, the partial uropygialectomy effects at 4 ages on production performance was determined. The experiment comprised 5 treatments (24 chicken/treatment), with 3 replicates for each (8 chicken/replicate). Experimental treatments consist of a control treatment T1, partial ablation of uropygial gland (uropygialecomy) were applied on T2, T3, T4 and T5 treatments at 3, 4, 5 and 6 weeks, respectively. Body weight, weight gain, feed intake and feed conversion ratio for males and females were recorded weekly. The results revealed remarkable significant (p<0.01) enhancing for partial uropygialectomy treatments than control group in all of males and females body weight, weight gain, feed intake and feed conversion ratio measurements. Variation ratio of production performance parameters for Partial Uropygialectomy treatments than control group was calculated to support the results. Best results were indicated in T2 treatment when partial uropygialectomy performed at week 3.

  The present study was conducted to investigate the effect of soluble probiotic on the production parameters of local Malaysian chicken (Akar Putra). A total of seventy two 1-day-old Akar Putra chicks were randomly assigned to three treatment groups, each having 3 replicates of 8 chicks. The treatments were as follows: (T1) control, (T2) probiotic supplemented at 1 g/liter tap water, (T3) probiotic supplemented at 2 g/liter tap water. The results revealed that supplementation of soluble probiotic at both the rates resulted in an improved performance of male and female Akar putra chicken. Birds who received 2 g of prepared probiotic per liter of water (T3) exhibited highly improved (p<0.05) body weight, weight gain and feed conversion ratio than other groups. It can be concluded that supplementation of prepared soluble probiotic would be economically beneficial in improving the production performance and health status of Akar Putra chicken.

  In most animals, myofibers number gets established before birth and postnatal growth is due to muscle hypertrophy, with very little contribution from muscle hyperplasia. The muscle myofibers exhibit different contractile, metabolic, physiological, chemical and morphological characteristics but the interaction between these factors and their outcome is not fully understood. Since, there is lack of literature regarding the skeletal muscle morphology of Red jungle fowl (RJ) and Malaysian village chicken (VC), therefore, the present study was undertaken with the aim to evaluate the morphology of skeletal muscle of Red jungle fowl (Gallus gallus Spadiceus) and Malaysian Village Chicken (Gallus gallus Domesticus) and commercial broiler chicken. A total of 150 unsexed birds consisting of 50 Red jungle fowl (RJ), 50 Malaysian village chicken (VC) and 50 commercial broiler (CB) were used in this study. Pectoralis major and bicep femoris were analyzed at the age of 1, 10, 20, 56 and 120 days post hatch. The number of muscle fibers in the breast and thigh muscles increased as the age advanced and the slow growing birds (RJ and VC) had higher Type I muscle fibers in breast and thigh muscles than fast growing CB. The percentage of Type 1 muscle fibers increased as the age advanced due to prolonged activity and also the type of muscle fibers changed throughout the age and activity. The importance of muscle fiber type changes is applicable to determine the future production of birds especially with regard to better quality meat of VC and RJ.
