<p><span lang="EN-US">The needs for chicken meat have been dominated by meat from exotic broilers (bred from imported parent). The potential of local broilers chicken in Indonesia is expected to be able to provide the meat for national needs for chicken meat. The objective of this research was to determine the day-old-chick (DOC) phenotypic characteristics of chickens in Indonesia that have the potential as broilers. The phenotypic characteristics are in the form of body morphometry, visceral organ weight and small intestinal histo-morphology. The chickens used were the DOC type of exotic Broiler, Kampung, exotic male Layer, KUB-1 and Pelung. A total of 125 chickens consisting of 25 chickens of each strain at posthatched age were observed for its body morphometry and its visceral organ weight, and small intestinal histo-morphology. The observed data were then analyzed by similarity analysis using MVSP 3.22 to create a dendogram with the Unweighted Pair Group with Aritmetic Average (UPGMA) method. Results showed that there were 2 different clusters from the level of similarity in their characteristics. Exotic broilers had 94.65% similarity to male exotic layer chicken and 92.26% to pelung chicken, while Kampung chickens had 90.16% similarity to KUB-1Chicken. In conclusion, it is indicated that the level of similarity of the phenotypic characteristics of pelung chickens were close to the type of exotic broiler and male exotic layer chicken. This level of similarity lead  to the expectation that pelung chickens potential to be a candidate for meat-type of local chicken.</span></p>

The main factor that must be considered in achieving the success of the broiler industry is feed. Processed peanuts from home industries produce waste material in the form of peanut hulls. This study aims to determine the effect of peanut hulls supplementation (PHS) on feed on the histological structure of the Pectoralis thoracicus (PT) muscle, small intestine, and the growth performance of broiler chickens. This study used 360 chickens then divided into 4 treatment groups with each group amounting to 90 with 3 replications. The control group (K) was given basal feed, perlakuan 1 (P1) group with PHS 0.25% /kg basal feed, group P2 with PHS 0.5%/kg basal feed, and group P3 with PHS 1%/kg basal feed. The treatment was carried out until the chicken was 18 days old. The parameters observed were chicken body weight at post-hatch age, 3, 6, 9, 12, 15, and 18 days, feed conversion ratio (FCR), histological structure of pectoralis muscle, and small intestine. Data were analyzed using One-way ANOVA, significance (P≤0.05). The results showed that body weight and FCR values of groups P1, P2, P3 were significant towards the control. The results of the pectoralis muscle treatment group were increased significantly compared to the control. The morphological results of duodenum and jejunum groups P1, P2, P3 were significantly increased towards the control. The conclusions of this study indicate that PHS in feed shows improved body weight, the FCR value, muscle performance of PT, and structure of small intestine of broiler chickens with the addition of the most optimal supplement of peanut hulls, which is 0.5%/kg basal diet.
