Abstract:
One hundred Local Turkey Poults brooded on commercial broiler starter mash for four weeks were utilized in a Completely Randomized Design Experiment to evaluate the effect of feeding varying levels of Rice Milling Waste (0%, 25%, 50%, 75% and 100%), on the haematological and blood chemistry indices of grower and finisher turkeys. Five grower and finisher diets were respectively formulated such that rice-milling waste was substituted for maize at 0%, 25%, 50%, 75% and 100%. The poults were randomly assigned to the five experimental diets, having 20 poults per treatment. Each treatment group was replicated twice with 10 poults per replicate at the grower and finisher phases. Feed and water were provided ad-libitum. The study lasted 20 weeks covering a growing period of 16 weeks and finishing period of 4 weeks. Haematological indices of interest (Hb, PCV, WBC RBC) and blood chemistry measurement (Creatine, Urea, Alkaline phosphate, Albumen and Globulin) were measured. Results obtained showed that substituting maize with 50% RMW produced superior blood quality in terms of Hb counts, white blood cell and red blood cells at the grower and finisher phases. Considering the biochemical values, 50% substitution also proved superior to other treatment groups in terms of Albumen, Globulin and Total protein concentration, at the grower and finisher phases. It was concluded that, substituting maize with 50% rice milling waste enhanced the haematological values and serum biochemical indices in grower and finisher turkeys, which in turn led to enhanced biological performance of the turkeys placed on this diet.

Abstract:
Rice bran oil (RBO) derived from rice bran (RB) which could use as an alternative raw material for biodiesel production. Rice bran (dedak) are used as feed for poultry, pigs, and some dairy cattle because they are relatively cheap and do not require processing. The utilization of these oil further cheapen the cost of biodiesel and increased the economonic value of RB. The choice of RBO as a raw material for biodiesel due to the rice bran oil’s potentials. RBO is considered to be one of the most nutritious oils due to its favorable fatty acids composition and a unique combination of naturally occurring biologically active and antioxidant compounds (oryzanol, tocopherol, tocotrienol, phytosterol, polyphenol, dan squalene). The research emphazised on esterification reaction because of the rapid increase of FFA content in RBO after the milling of rice. Storage time of RB increased the FFA content. Mixing velocity dan time reaction was the other two variables which are affecting the esterification reaction. Those two variables are studied in this experiment. Experiment were designed to examine the mixing velocity and temperature reaction to the conversion of fatty acid methyl ester (FAME). Reaction condition 20:1 molar ratio methanol to FFA content and 5%-v/v catalyst (to the oil) was used in all experiments. Mixing velocity and time reaction was arranged as follows: 500, 750, 1000 rpm and 40, 50, 60oC, respectively. Research conducted in four parts: soxhlet extraction with n-hexane as a solvent; oil-solvent separation process; and the last step was esterification reaction. Reaction conducted on three neck round bottom flask equipped with magnetic stirrer, refluk condenser and thermometer. Crude product was separated first from unreacted methanol, glycerol, and catalyst prior to physical analyzed of biodiesel’s properties. Conversion of FAME was calculated from acid value difference, after and before reaction conducted. It was found that mixing velocity influenced the FAME conversion not significantly (specially in crude rice bran oil high fatty acid content esterification); increasing in temperature will increase the FAME conversion; kinetic reaction controlled by chemical reaction; and biodiesel product from this research already fullfill the requirements of Indonesian Standard of Biodiesel (FBI-SO1-03).

Abstract:
This study was aimed at finding appropriate levels of machine set up for small-sized rice milling machine in order to improve rice milling effectiveness. Small rice milling machines are used by farmers to reduce the reliance on commercial rice mill. However, they are found to produce greater quantities of broken rice grains than large-sized rice milling machine. This study investigated three factors of machine setup that would lead to smallest percentage of broken rice grains, i.e. size of hopper feed, gap adjuster, and outlet regulator. Each factor had three levels thus 3 x 3 factorial design was used to investigate the factors. It was found that all the three factors had significant impact on the number of broken grains. The optimum parameter settings that led to the smallest percentage of broken rice grains were as follows: size of hopper feed at 12 cm2, gap adjuster at 5 mm, and outlet regulator at 5 cm.

Abstract:
Several efforts are being made to find the possibilities of utilizing agro-industrial by products in poultry nutrition. The deployment of maize milling waste for feeding broilers has a promise for reducing its nuisance value, yet enhancing the feeding of broilers. An eight weeks' study was carried out with 108 day-old Anak broiler chicks, to evaluate the performance of broiler chickens fed diet containing maize milling waste as a replacement for maize. Maize milling waste was analyzed for its proximate composition. It was then used in formulating starter and finisher broiler diets at 0.0%, 10%, 30%, 50% dietary levels. The formulated diet was fed to the chicks in a Completely Randomized Design (CRD) experiment. The parameters evaluated were the initial body weight, final body weight, average feed intake, feed conversion ratio. The results obtained indicated that broiler chicks on 0.0% maize milling waste recorded the highest weight gain and feed conversion ratio followed by birds on 10% maize milling waste inclusion level. The feed intake of birds increased as the level of replacement increased. Birds on 50% milling waste had the highest feed intake which was significantly different (P<0.05) from the other treatment diets. From the results of this study, the growth performance in diet 1 (0.0%) maize milling waste inclusion level was superior to others, followed by diet 2 (10%) inclusion level. Therefore, for efficient utilization and without deleterious effects, 10% inclusion level of maize milling waste should be used in feed formulation.

Abstract:
The nutritional value or quality of dietary proteins used for poultry feed formulation varies: amino acid availability is an important measure of protein quality. Determination of ileal digestibility values has become the preferred method for estimating amino acid availability. This review discusses the different approaches to the expression of digestibility results, including correction for endogenous loss and the derivatisation of standardised values. Sources of variation in values include, the assay protocol, anti-nutritional factors in feedstuffs and feed milling. Feed formulating with ileal digestibility values should allow higher dietary inclusion levels of protein feedstuffs of lower quality provided that values of different feedstuffs are additive, the age of the bird and the use of feed enzymes are considered. An Australian data set of "ileal digestible amino acid values in feedstuffs for poultry" that has recently be published is described. This overview is intended to stimulate interest in the generation and application of ileal digestibility as a method for estimating amino acid availability in poultry nutrition.

Abstract Feedstuffs and mixed feeds used for poultry and pig nutrition in Colombia were analyzed for aflatoxins by using a liquid chromatographic technique with a limit of detection of 1 μg/kg for each aflatoxin (B1, B2, G1 and G2). Samples of grain sorghum, maize, processed soybean, rice meal, cottonseed meal, and poultry and pig feeds, representative of Colombian production for the 1995–1996 harvest, were taken from feed-manufacturing plants in various cities. Aflatoxins were detected in 11 of 45 samples of sorghum, 4 of 33 samples of maize, 8 of 22 samples of rice meal, 15 of 17 samples of cottonseed meal, 1 of 12 samples of other feedstuffs, 12 of 30 samples of poultry feed, and 7 of 16 samples of pig feed. Aflatoxins were not detected in soybean. Only 9 of 58 positive samples contained total aflatoxin levels exceeding maximum tolerable limits in Colombia.

Abstract:
A 12 – week feeding trial involving 64 weaner rabbits in a completely randomized design was carried out to determine the substitution value of a mixture of rice milling by-products (in the ration of 1: 1: 2 respectively for straw, busk, hull, and bran) for maize in the diets of New Zealand white type weaner rabbits at four substitution levels: 0%, 50%, 75% and 100%. Rabbit on the experimental diets recorded higher feed intake of 68.83, 68.11, and 66.97gm respectively for 50%, 75% and 100% as against 52.71gm for 0%. The difference in feed intake between the group on 0% and the group on experimental diets became significant (P < 0.05) at 50% dietary substitution level, but there was no significant (P > 0.05) difference among the group on the experimental diets. Rabbits on 50% substitution level recorded the highest feed intake (68.83gm) while the group on 100% recorded the highest feed conversion ration (15.72). Body weight gain of the groups showed significant difference (P < 0.05). The mixture of rice milling by-products used for this study contained 9.10% crude protein, 30.4% crude fibre, 0.29% calcium, 0.19% phosphorus and 2.01 kcal/kg metabolizable energy levels. The result of this trial suggest that a mixture of rice milling by-products could substitute maize in weaner rabbits diets up to 50% with good result.

Abstract:
The term traceability refers to recording of flow of products along the food chain from production to consumption with inclusion of all intermediate applications involved in processing/packaging stages. The aim for establishing traceability in the food chain is to provide the timely identification and recall of batches of product from the market when a risk threatens the health of consumers. Since compound feed products are basic inputs in livestock and poultry production, ICT-based feed traceability systems can be considered as a initial step in food traceability management. These systems are simply information recording systems that are designed to trace and track the flow and characteristics of animal feed along the feed supply chain. This paper describes the architecture and some functional properties of a feed traceability system called as the “feed TRace”, focusing particularly on compound feed and integrated poultry meat industries. The feedTRace aims to improve compound feed supply chain management, to increase feed safety and quality control, and to gain marketing competencies with traceable products in compound feed industry. The system is currently under beta stage, and is tested in two high capacity feed milling plants and an integrated broiler company located inAdana province of Turkey.

Abstract:
<p>Rice bran is a feed ingredient as a result of the rice milling process which widely used as an energy source in the feed formulation in the chicken diet. Rice bran contains various nutrients such as oil, protein, carbohydrates (especially starch), beta-glucans, and pectins. Rice bran contains bioactive compounds that have positive effects on the chicken performance and health. Recently, rice bran’s bioactive compounds have been developed as a source of making functional feed. The objective of this study was to review the bioactive compounds in rice bran and their benefits in order to produce chicken’s functional feed. The results of the study showed that rice bran contains oryzanol as an important bioactive compound that has high antioxidant activity. Furthermore, other bioactive compound, lysolecithin, has an ability to reduce cholesterol content in blood, meat and eggs of chicken. Besides, rice bran extract is reported to exert antibacterial activity and has immunomodulator function. It was concluded that the bioactive compounds of rice bran is potential to be used as a substance for making functional feed for chickens.</p>

Abstract:
Rice bran arises as a by-product from rice milling industry. The anti-nutritional substances such as phytate, non-starch polysaccharides, protease inhibitor and lectin limit the nutritional value of this by-product. This research was directed toward the nutritional improvement of defatted rice bran (DRB) using feed enzymes to degrade these anti-nutritional factors. Three growth experiments and two tube feeding experiments were carried out to investigate the effect of phytase, carbohydrase and protease enzymes (supplied by Finnfeeds International) on broiler performance, mineral retention, nutrient digestibility, digesta viscosity and bone characteristics of chicken fed defatted rice bran based broiler diets. Enzyme supplementation of diets was conducted to assess the effects of individual and a cocktail of enzymes and/or lactobacillus culture. The data showed that inclusion of DRB at more than 150 g/kg without additional inorganic phosphate reduced feed intake, growth, bone mineralisation and produced the symptoms of rickets in broiler chickens. Experimental phytase successfully released phosphorus from DRB which counteracted the symptoms of a phosphorus deficient rickets-producing diet and improved feed intake, growth and bone mineralisation. Data presented in this study indicate that inclusion of DRB in broiler diets did not produce viscous digesta in the gut and carbohydrase supplementation did not improve bird performance, nutrient digestibility and mineral retention. The digesta viscosity was not decreased by carbohydrase; therefore, the non-starch polysaccharide (NSP) content of DRB did not play an important role in production of viscous digesta. Supplementation of DRB based broiler diets with protease improved dry matter (DM) and protein digestibility and P retention; therefore, the improvement in feed conversion ratio (FCR) was a result of better utilisation of nutrients. The data showed that there is a potential to decrease the phytate and lectin content of DRB broiler based diets by supplementing diets with phytase and protease.
