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

Abstract

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