  Problem statement: The aim of this study was to verify the effects of methionine and threonine supplementations higher than the NRC recommendation on growth performance, liver function enzymes, blood parameters and immune tissues of broiler chickens challenged with infectious bursal disease. Approach: A total of 450 day-old male broiler chicks were assigned to nine groups. Chickens were fed by three graded levels of DL-methionine [NRC (M1), 2 times NRC (M2) and 3 times NRC (M3)] and three graded levels of L-threonine [NRC (T1), 2 times NRC (T2) and 3 times NRC (T3)] from day 1-42 of age. On day 28, all birds were challenged with a commercial live-IBDV vaccine. Results: Body Weight Gain (BWG) and Feed Intake (FI) and Feed Conversion Ratio (FCR) were significantly influenced by the dietary treatments in starter phase and either methionine or threonine at the highest levels significantly decreased BWG, FI and FCR in broiler chickens. A similar trend by methionine and threonine at the highest levels was noted on BWG and FI in grower phase. The highest level of threonine significantly increased spleen weight on day 28 (pre-challenge) and 14 days post challenge. At 14 days after challenge, dietary supplementation of methionine at NRC recommended level (M1) significantly increased the serum concentrations of Alanine Aminotransferase (ALT), aspartate Aminotransferase (AST) and Lactate Dehydrogenase (LDH). In the T3 group, the serum concentrations of AST and LDH were significantly decreased, whereas the serum uric acid concentration was significantly increased. Conclusion/Recommendations:
In conclusion, our data suggest that the methionine and threonine requirement of male broiler chicks is higher for growth performance than was suggested by the last NRC committee and liver function enzymes results showed that methionine and threonine supplementation three times higher than NRC requirements in broiler chickens has not toxic potential. In conclusion, our data suggest that the methionine and threonine requirement of male broiler chicks is higher for growth performance than was suggested by the last NRC committee and liver function enzymes results showed that methionine and threonine supplementation three times higher than NRC requirements in broiler chickens has not toxic potential.

  Problem statement: The aim of this study was conducted to determine the effects of supplementing methionine and threonine higher than the National Research Council (NRC) recommendation in the diets on immune responses of broiler chickens challenged with Infectious Bursal Disease (IBD). Approach: A total of 450 day-old male broiler chicks were assigned to one of the nine dietary treatments. Three levels of methionine (NRC (M1), 2 times NRC (M2) and 3 times NRC (M3)) and 3 levels of threonine (NRC (T1), 2 times NRC (T2) and 3 times NRC (T3)) were fed. On day 28, all birds were challenged with a commercial live-IBDV vaccine. Results: Antibody titer against IBD and ND were influenced by interaction of threonine and methionine. On 7 days after IBD challenge, ND antibody titer of the broilers receiving the highest level of methionine and threonine was significantly higher than that of other treatment groups. Lesion score of the bursa of the broilers receiving control diet was significantly the highest compared with the other treatments. Conclusion/Recommendations: The results obtained on the present study indicated that threonine and methionine requirements of broiler based on recommendation of NRC are not sufficient to meet the requirement of the new commercial poultry and commercial broiler companies under non-hygienic condition.

  The aim of this study was to recognize the palatability of Ground Cinnamon (GS) treated Oil Palm Decanter Meal (OPDM) on goats. Goats were placed in an individual cage attached with 3 separated adjustable feed containers. It was spent for adaptation period of 7 days to familiarize animal with the experimental feed. Then all animals were offered with three alternatives feed namely RS as a standard feed, untreated OPDM (UDM) and GS treated OPDM (GDM) over a 15 days experimental period. The chemical composition including ash, Organic Matter (OM), Crude Protein (CP), Ether Extract (EE), Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) of both GDM and UDM was not significantly different (p>0.05) among experimental feed. Intakes on day 1 and average on day 5, 10 and 15 were significantly different (p<0.05) among four different experimental feeds. After removing of RS on day 5, intake of GDM significantly (p<0.05) increased and be the highest in comparison with UDM and NG. In conclusion, the chemical composition of GDM was not different from that of UDM therefore GDM could be used as animal feed. GDM could be accepted as edible feed for goat as it was higher intake of than that of UDM.
