EVALUATION OF ORGANIC AND INORGANIC SELENIUM RATIO AS FEED ADDITIVE ON BLOOD PROFILE AND EGG LAYER NUMBER
This study aims to evaluate and analyze the supplementary feeding of selenium (Se) on the blood profile and the number of eggs produced by layers. This study took the main object in the form of 60-week-old laying hens with Isa Brown strain. The research was conducted with the method of Completely Randomized Design (CRD) four treatments and six replicates, then tested further Duncan. The results of this study explained that supplementary feeding in the form of selenium (Se) with several doses had a significant effect on blood profile (Hemoglobin, Erythrocytes, Hematocrit, and Leucocytes) and the number of eggs produced by laying hens. The best dose of selenium was shown in treatment three (Commercial feed + organic selenium dose 150 grams/ton feed inorganic selenium + vitamin E dose 1000 grams/ton feed). The best treatment results are due to the additional feed contained in organic selenium as an antioxidant, increase immunity, fertility, improve reproduction, and even prevent various diseases such as arthritis, cancer, cardiovascular disease, muscular dystrophy, lymphoblastic anemia, and immunodeficiency which is good for the health of the body layer.
