Effect of energy and dose of vitamin E selenium on improving the reproduction performance of Joper brood stock

Production performance in Joper broodstock can be improved through increased feed energy and vitamin E-selenium supplementation. This study used 400 laying hens Isa Brown aged 35 weeks 15 Sentul rooster 68 weeks. a factorial completely randomized design with 2 factors, namely metabolic levels (2,700 2,800 kcal/kg) supplementation doses (0, 25, 50, 75 100 ppm) where each treatment 10 repeated 4 times. The dose of selenium is 0.001 ppm/mg E. level has very significant effect ( P < 0.01) on (feed, protein energy) intake HDP. E- had HDP 0.05) FCR. interaction between the two average 113-115 g/day, 21.90-22.20 g/day 308-317 kcal/bird. 76.70-83.00%. conclusion this that 2800kcal/kg at ppm improve productivity broodstock.
