Improving Reproductive Performance of Laying Hens with a Combination of Selenium: Effects on FSH and LH Hormones

Abstract : This research aims to evaluate the provision of inorganic and organic selenium in feed on the reproductive status of layers. This research took the main object as layers aged 60 weeks with the ISA Brown strain. The research used a Completely Randomized Design (CRD) method with Duncan’s advanced test. The results of this study explain that giving additional feed in the form of selenium (Se) with several doses of basal feed plus inorganic selenium 1000 g/ton of feed and organic selenium 225 g/ton of feed showed a significant increase in the FSH hormone, while giving basal feed plus inorganic selenium at a dose of 2,500 g/ton of feed and organic selenium at a dose of 375 g/ton of feed gave a significant increase in the LH hormone. The best treatment results are because the additional feed contained in organic selenium can help layers improve reproduction to produce good quality eggs.
