Abstract

One experiment was conducted with a total of 2000 BROILER BREEDERs (Lohman strain) at 74 weeks of age, which lasted for 10 weeks. Birds were randomly assigned to two dietary treatments varying in dietary crude PROTEIN (CP). The reduced-CP diet had dietary CP level approximately 1.5 percentage units lower than the control (15.5 vs 14.0%). By supplementing 0.13 and 0.1% of DL-methionine and L-HCl-lysine to the reduced-CP diet, respectively, the sulfur amino acids to lysine ratio was kept similar between the control and the reduced-CP diet. Data were subjected to one-way ANOVA in a completely randomized design with 2 treatments and 4 replicates. Results showed that egg shell thickness, HATCHABILITY, and the Hemagglutination Inhibision (HI) response against New Castle and Influenza from reduced-CP group were not significantly different from the control group. Hen-day egg production was also remained unchanged throughout the experiment. Nevertheless, it was numerically higher in the low-protein group than the control group. In conclusion, egg production, HATCHABILITY and the immune response of BROILER BREEDERs can be maintained on a reduced-CP diet (90% of the industry norm) when the contents and ratio of sulfur amino acids to lysine kept constant.
