| ABSTRACT This study was conducted to investigate the effects of dietary oxidized oil and natural polyphenol antioxidants on laying performances and egg quality of laying hens. A total of two hundred, 61-week-old Lohmann Brown laying hens were divided into five groups, consisting in four replicates of 10 birds each. They were fed one of the five experimental diets (fresh oil only, oxidized oil without antioxidants, oxidized oil with vitamin E 200 ppm, oxidized oil with vitamin E 100 ppm + Cabanin CSDⓇ 100 ppm, oxidized oil with Cabanin CSDⓇ 500 ppm)respectively, for 6 weeks. There were no significant differences in laying performances and egg weight among the treatments. However, egg mass in group fed oxidized oil with vitamin E 100 ppm + Cabanin CSDⓇ 100... |

| ABSTRACT This experiment was conducted to evaluate the dietary supplementation of canola meal (CM) on the growth performance, carcass characteristics, antibody titers against Newcastle disease virus and Infectious bronchitis virus, and blood profiles of broiler chickens. In total 600 day-old feather-sexed Ross male broiler chicks were randomly assigned into five treatments with six replicates of 20 birds each for 35 days. Treatments consisted of five experimental diets containing 0 (control), 3, 5, 10, or 15% canola meal (CM). Final body weight (BW) was not affected by the dietary treatments. Daily BW gain (DWG) and feed intake linearly decreased as dietary CM inclusion increased during the starter phase (p<0.0001), but not during the grower and total... |

| ABSTRACT Two experiments were conducted to evaluate the effects of β-mannanase on egg production performance, egg quality, intestinal microbiota, viscosity, and ammonia concentration in laying hens. In Exp. 1, two hundred and seventy 30-wk-old Hy-Line Brown laying hens were assigned to 6 diets arranged in a 3 × 2 factorial of three levels of MEn and CP [(a corn-soybean meal based diet (HEHP), a diet containing 50 kcal of MEn/kg and 1.0% less energy and CP than the HEHP (MEMP), and a diet containing 80 kcal of MEn/kg and 1.5% less energy and CP than HEHP (LELP)], and β-mannanase supplementation (0 or 0.04%). In Exp. 2, A total of two hundred and sixteen62-wk-old Hy-Line Brown laying hens were assigned to 6 dietary treatments in a 3 × 2 factorial... |
