Performans Produksi Itik Alabio Petelur Pada Berbagai Tingkat Penggunaan Gulma Bebek (Lemna minor) dalam Ransum

Abstract

Feed is the largest component of costs in the production of laying ducks. Therefore, farmers seek to use the cheaper feed ingredients but can still meet nutritional needs and maintain good production performance of Alabio laying ducks. This study aims to determine the effect of the use of duckweeds in diets on the production performance of alabio ducks including egg production, feed consumption, feed conversion, income over feed-cost, egg weight, yolk-color, and cholesterol levels in duck eggs. The study used a Completely Randomized Design (CRD) method with four treatments and five replications, each of which consisted of three Alabio laying ducks. The research treatments were P0 = 0% the use of duck weed, P1 = 10% the use of duck weed, P2 = 20% the use of duck weed, and P3 = 30% the use of duck weed for each of the diet treatment. The results showed that the use of duck weeds (Lemna minor) up to 30% in diet had no effect on the amount of egg production, percentage of egg production, feed conversion, egg weight, and IOFC values. However, it affected the feed consumption, yolk color and cholesterol content of Alabio duck eggs. The feed consumptions were not different from the control diet until 20% use of duck weeds, but decreased at 30% due to the increased of crude fiber feed. The yolk color scores increased and the egg cholesterol content decreased with increasing use of duck weeds in diets. Duck weed has a great opportunity to be used as a source of protein feed.
