Main Article Content
The objective of this study was to utilize the superiority of agricultural waste in form of soybeanÂ hull and shrimp wastes and their combination on egg layer duck. This feed contains starbioÂ probiotic functions for fiber digestion (soybean hull waste) and chitin (from shrimp waste). TheÂ expectation was that there would be duck ration which is able to increase egg production andÂ quality and brighter reddish egg-yolk which is attractive and full of nutritions. The research wasÂ conducted in three stages. Stage I is Nutrient Digestional Value Test on the formula of soybeanÂ hull and shrimp wastes mixture on Duck Feed Contained Starbio." Stage II : experiment onÂ "Mixture Formulation of soybean hull and shrimp wastes mixture on Duck Feed ContainedÂ Starbio Probiotik for Increasing The Performance of Egg Layer Duck" and III experiment onÂ "The Production of Reddish Duck Egg-Yolk With Feed Contained soybean hull and ShrimpÂ Wastes Mixture". The experiment concluded that : I) the provision of soybean hull and
shrimp had significant effects on digestability of feed dried materials, but conversely hadÂ no effects on protein digestability and crude fiber, as well as on egg produktion and quality.There was no interaction between two materials in the treatment. 2) Shrimp waste tended toÂ have effects on daily egg production of egg layer duck; 3) Yellow color of the eggs couldn'tÂ change to be reddish yet, since xanthophyl content had already lost in over-dried and already
expired shrimp wastes.
Key Words : shrimp waste, soybean hull, probiotic, egg-yolk color
