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

/in /by

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.

Evaluation and Analysis of the Effects of Feed Supplements, Including both Organic and Inorganic Selenium, on the Production of Layer Eggs

This research aims to evaluate and analyze the provision of additional feed in the form of selenium (Se) on the performance of egg production produced by layers. This research took the main object in the form of 60 weeks old laying hens with the Isa Brown strain. The research was carried out using a Completely Randomized Design (CRD) method with Duncan’s advanced test. The results of this study explain that providing additional feed in the form of selenium (Se) in several doses has a very real influence on egg production performance (egg weight, feed intake, mortality, daily egg production, and FCR). The best dose of selenium was shown in treatment three (commercial feed + organic selenium dose of 150 grams/ton of inorganic selenium feed + vitamin E dose of 1000 grams/ton of feed). The presence of selenium and vitamin E given as additional feed for laying hens can increase egg weight, egg production, minimize mortality rates, and increase appetite.
