| Popis: | The effects of betaine supplementation on productivity, egg quality, blood components, and liver amino acid concentration were examined in laying hens using a diet with differing levels of CP. A total of 540 Hy-Line Brown laying hens were allotted to 6 treatments with 5 replications for 24 weeks. Treatments were designed with 3 levels of CP (14, 16 and 18%) and 2 levels of betaine supplementation (0 and 600 ppm) in the diet. Egg production, egg mass, and feed conversion were found to be improved significantly as dietary levels of protein increased (P |
