Fifty-four samples of wheat, representing duplicate samples of nine varieties grown in three environments, were included in chick bioassays using rapidly growing broilers, complete diets, and enzyme supplementation to remove the deleterious effects of non-starch polysaccharides. An insoluble ash marker was included in the diets, which allowed calculation of apparent digestibilities of CP and AA in the grain from analysis of the ileal contents obtained after sacrifice of the chicks at 17 d of age. The wheat cultivars contained from 13.5 to 16.8% CP and differed in the percentage of specific AA, with Pro, Glu and Phe making up proportionately larger parts of high CP samples than low CP samples. Without enzyme supplementation, the digestibility of CP varied from 83 to 88% and that of specific AA from 76 to 94%, determined in part by the class and variety of wheat. Xylanase enzyme supplementation improved the digestibility of protein by an average of 4%, and reduced the differences in digestibility between wheat samples. These results suggest that variation between wheat samples should be taken into consideration when formulating broiler feed, especially when formulation is for specific AA. Enzyme supplementation may provide a partial alternative to using high-quality protein sources or supplementing with synthetic AA. Key words: Broiler chicken, digestible amino acids, digestible protein, wheat, enzyme

Abstrak Penelitian ini bertujuan mengetahui kombinasi terbaik tepung ubi jalar merah dengan ragi sebagai pakan sinbiotik, yang dicampur ke ransum broiler. Jumlah materi yang digunakan sebanyak 100 ekor ayam broiler. Parameter yang diamati berupa organ pencernaan, yang diamati terdiri dari gizzard (rempela), usus halus, usus besar. Metode penelitian terdiri dari persiapan yaitu membersihkan bagian dalam kandang ataupun lingkungan sekitar kandang dengan menggunakan desinfektan kandang, pemeliharaan ayam broiler selama 35 hari, dan perlakuan  pada penelitian menggunakan ransum ayam  pedaging yang dicampur tepung ubi jalar dan ragi tape, yang dibedakan menjadi enam macam ransum perlakuan, dengan taraf tepung ubi jalar dan ragi tape yang berbeda-beda. Hasil penelitian kombinasi pemberian tepung ubi jalar merah dengan ragi sebagai sinbiotik tidak memberikan pengaruh nyata terhadap pertambahan bobot organ pencernaan ayam broiler (Gizzard, Usus Halus, Usus Besar). Level pemberian terbaik menunjukkan bahwa berat gizzard terdapat  pada P2 = 103 gram, berat usus halus terdapat pada P4 = 106 gram, berat usus besar terdapat pada P2 = 86 gram, masing_masing  memperlihatkan sebagai berat yang baik atau unggul dengan berat yang tertinggi dibandingkan dengan berat gizzard yang memiliki berat yang berbeda. Kesimpulan dari hasil penelitian bahwa  pemberian perlakuan tidak berpengaruh nyata terhadap berat organ pencernaan ayam broiler.   Kata kunci : Tepung Ubi jalar, Ragi, Terhadap Pertumbuhan Berat Organ Ayam Broiler   Abstract The study aims to find out the best combination of red sweet potato flour with yeast as sinbiotic feed which is miked to the broiler ration. The amount of material used is 100 broiler chickens. The parameter that is observed is digestive organs; qizzard, small intestive, large intestive. The methodology of the research is quantitative. It contains of preparation of cleaning the insside of cage or the envivonment around the cage by using disintecting the cage, the maintenance of broiler chicken for 35 days, and the treatment in the research is using broiler rations miked with sweet potato flour and yeast of tape, six kinds of treatment rations, with different levels of sweet potato flour and yeast of tape. The results of the research of the combination of red sweet potato with yeast as a sinbiotic is it does not give significant effect to inccrease of broiler gastrroinstestinal weight (qizzard, intestine, colon). The best level of administration shows that the weight of qizzard was found at P2=103 gram, in P4=106 gram, the weight of the large intestine or colon is found ad P2=86 gram, pach of it shows that the good weight or superior weight of the highest compared to the weight of the highest compared to the weight of different weight of qizzards. The conlusion of the research is there is no real effect to broiler disentive organ weight in the treatment.

Corn-Cob Meal (CCM) is a waste product derived from maize grain shelling corn cob which constitutes nuisance to the environment and it can be included in poultry diet in order to reduce competition between man and animal. Hence, a 63-day feeding trial was conducted in a completely randomized design to determine performance characteristics and blood profile of broiler chickens fed corn-cobs based diets with or without enzyme supplementation. One hundred and sixty five (165) birds were randomly allotted into five dietary treatment groups; T1: (0% CCM), T2 (10% CCM without enzyme), T3 (20% CCM without enzyme), T4 (10% CCM with enzyme), T5 (20% CCM with enzyme) with each treatment comprising three replicates of eleven birds per replicate. Parameters measured include performance characteristics, haematological and serum biochemical indices. The result revealed that there were no significant difference (P>0.05) on performance characteristics of broiler chicken observed except for Average Daily Feed Intake (ADFI) and the Feed Conversion Ratio (FCR). Birds fed 10% and 20% CCM based diet without enzyme recorded the highest value of ADFI (129.38 g/b/d and 130.85 g/b/d) while birds fed 20% CCM based diet with enzyme supplementation had the best FCR value (2.18). The haematological parameters were not significantly influenced (P>0.05) by the diets except for lymphocytes and heterophil count with the highest lymphocytes value in T2 (68.00%) and the lowest value in T5(53.67 %). Birds on T5 had significantly (P<0.05) highest heterophil value (40.67%). The serum biochemical indices were not significantly influenced (P>0.05) by the diets except for aspartate aminotransferase. However, values obtained in this study fell within the normal range recommended for healthy broiler chicken. Based on this result, it can be concluded that CCM with enzyme supplementation can be incorporated into broiler diet up to 20% without any detrimental effect on their performance and blood profile.
