PEMANFAATAN DUCKWEED (LEMNA MINOR) DALAM RANSUM UNTUK MENINGKATKAN WARNA YOLK TELUR DAN MENURUNKAN KADAR KOLESTEROL TELUR ITIK ALABIO

Abstract

The large component of feed costs (70%) in the production cost of laying ducks requires farmers to find the cheaper feed ingredients. However, the feed diets still maintain the quality of eggs produced which are characterized by high egg weight, yolk color and Haugh Unit, but are also expected to have low cholesterol levels. Duck weed (Lemna minor) is a type of water weed that has the potential to be used as a feedstuff  in duck feed diets.  Duck weed contains protein that has a high concentration of essential amino acids such as lysine, methionine, and high in minerals. This study aims to determine the effect of giving weed duck in the feed diet on egg weight, internal quality and cholesterol content of Alabio duck eggs. The study was conducted at the Poultry Production Laboratory, Animal Husbandry Study Program, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. 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 in the treatment diet, P1 = 10% the use of duck weed in the diet treatment, P2 = 20% the use of duck weed in the diet treatment, and P3 = 30% the use of duck weed in the diet  treatment. The variables observed were egg weight, Haugh Unit (HU), egg yolk color and Alabio duck cholesterol content. The results showed that the administration of Duck Weed (Lemna minor) up to 30% had no effect on the weight of eggs and HU of Alabio duck eggs. However, administration of Duck Weed (Lemna minor) in the feed diet can significantly increase the value of the color of the yolk and reduce the cholesterol content in Alabio duck eggs. Giving Duck Weed (Lemna minor) up to 30% in the ration can reduce cholesterol content from 47 mg (%) to 28.48 mg (%).
