In plant products such as sorghum and wheat, 50-70% of total phosphorus is bound in the form of phytin-P, which is unavailable to poultry due to the lack of significant endogenous production of the enzyme phytase.Â As a consequence, nitrogen retention and amino acid utilisation are reduced due to the reduction in protein digestibility.Â The objective of this study was to determine the influence of a commercial xylanase and phytase alone and in combination on the apparent amino acid digestibility of wheat and sorghum.Â The experimental diets were fed in mash form to three replicate pens (6 male birds per pen) for 5 days. On day 42, all birds were euthanatised by an intracardial injection of sodium pentabarbitone solution, and the contents of the lower half of the ileum were collected. Amino acid concentration of ileal digesta samples was determined. The enzymes used were: natuphos phytase (5,000 FTU/g), xylanase (55,000 EXU/g) and b-glucanase (1,200 BGU/g) as well as several side- activities (cellulase and protease); the recommended inclusion rate is 120 g/tonne. Analyses were performed using statistical analysis software SAS. In conclusion, inclusion of xylanase alone in wheat based broiler diets is advantageous through positive effects on the digestibility of all amino acids.Â In sorghum based diets, there was no improvement in amino acid digestibility with xylanase or phytase supplementation.

Dietary protein and amino acid supply is the most expensive component of poultry diets. Therefore several efforts made by the industry to minimize the cost of the protein portion of the diet. Accordingly, there has been a recent move to use digestible amino acid values in the formulation of poultry diets. The efficiency of protein utilization depends to a large extent on the amino acid composition of the diet. The study was conducted to determine the digestible methionine requirement of broilers during the starter periods. One hundred and seventy five (175) chicks were allocated to 5 treatments with five replicates of seven chicks per replicate in a completely randomized design. Chicks were fed experimental diets from one day old to 21 days of age. Dietary treatments included 5 titrated levels each of digestible methionine (3.0, 4.5, 6.0, 7.5, and 9.0 g/kg diet) added to a basal diet. The allowance of digestible methionine, rather than digestible sulphur amino acids was used in formulating the diets.Â Supplemental synthetic DL-Methionine which were considered to be 100% digestible were added to diets to obtain the concentration of the digestible amino acid. Each week until the conclusion of the trial, birds were individually weighed, feed intake per pen was measured, and feed conversion ratio (FCR) was computed. This study suggested that the digestible methionine requirement for broiler starter is 4.7 g/kg for optimal body weight gain and 4.6 g/kg for optimal feed conversion ratio.Â (Animal Production 12(1): 6-11 (2010)Key Words: amino acid, broiler, digestible, methionine, starter

In general, the determination of the price of cattle is based on the condition of the cattle's body. This will result in an unsatisfactory transfer of revenue value for farmers, because the bargaining position is still weak. In addition, transactions in the marketing chain of beef products and their by-products have not yet been solidly established, so the obligations and rights of some parties are not guaranteed. The objective was to analyze the role of stakeholders in each supply chain and distribution of value chains as revenue in the marketing transactions of cattle, beef, and derivative products. The study was conducted in West Timor, which has 85.0% of the cattle population in NTT. Four sample districts (Kupang, TTS, TTU and Belu) in 8 sample sub-districts or 16 sample villages were included in the study. Respondents in marketing activities consisted of farmers, village traders, sub-district/district traders, slaughter traders, inter-island traders, by-product/waste traders, as well as beef, cowhide, bone, and fat/blood processing industries. Data collection were conducted by a questionnaire-based interview. The data were analyzed descriptively-quantitatively with a supply chain analysis model. It canbe concluded that (1) Market supply chains include cattle traders (farmers, village traders, sub-district traders, inter-island traders and slaughtering traders), as well as beef traders (fresh beef retailers, frozen beef exporting traders, and processed beef products traders); (2) The ideal model of the value chain in the form of revenue share from marketing of cattle, beef, processed beef products, by-products, and cattle waste has not been fully established in NTT; (3) The ideal model includes five marketing blocks (cattle block, beef block, processed beef block, by-product block, and waste block).

The objective of the study was to investigate broiler immune responses during the starter phase to graded levels of digestible lysine. This experiment used 175 mixed sex broiler chickens from 1 to 21 days of age. Seven chicks were selected and allocated to each floor pens. Chicks were fed experimental diets from one day old to 21 days of age. Dietary treatments included the following levels of digestible lysine: 6.0, 8.0, 10.0, 12.0 and 14.0 g/kg diet. Supplemental synthetic L-Lysine-HCl which was considered to be 100% digestible was added to diets to obtain the concentration of the digestible amino acid. At 21 days of age, two chickens from each pen with body weights close to the pen mean were selected for evaluation of immunological variables. Immune organs (spleen and bursa), cellular immune response (skin test), and antibody production against infectious bronchitis virus (IBV) were determined. Blood samples (plasma) were taken from the same birds to determine antibody titer against IBV. The birds were euthanized, and immune organs (spleen and bursa) were removed, and weighed individually. The results showed that spleen and bursa weight of birds fed diet containing 6.0 g/kg digestible lysine was significantly lower than those given diet containing 10 to 14 g/kg of digestible lysine. Toe web thickness of chickens fed diet containing 6.0 g/kg digestible lysine was significantly lower than the birds fed diets containing 14 g/kg digestible lysine. In conclusion, diet containing 8.0 g/kg appeared to have greatest potential to modulate immune response among other levels. However increasing levels of lysine did not have significant effect on antibody production. Key words: amino acid, lysine, broiler, digestible

Commonly, native chicken is raised in an extensive management system. The chickens were free toscavenge in the backyard, and eat a wide variety of feeds including, rice, corn, insects, or even grit. Grit is anabrasive material that can help to grind feedstuffs and use as a source of mineral for chicken. In anintensive farming system, native chickens are given full feeding program throughout the production period,without grit. The objective of this research was to study the development of gastrointestinal tract andcarcass bone of native chickens supplemented to grit. Eighty chickens were used in the study usingrandomized block design. The four treatments were: R0 = basal feeds without grit ; R1 = R0 + grit 0,25% ofbody weight ; R2 = R0 + grit 0,50% of body weight ; R3 = R0 + grit 0,75% of body weight. The results showedthat administration of grit up to the level of 0.75% body weight significantly increased grit consumption,digestive tract length, gizzard weight and carcass bone weight of native chicken.
