Effect of using shrimp head flour and small sea fish on duck egg production and egg quality.

The local feed ingredients in the form of fishery wastes which are widely available in the Riau Islands Province include Shrimp heads and Small sea fish or Rucah fish. This study aims to determine the effect using of both types of fisheries wastes on the production and quality of duck eggs. The study was carried out in the Dompak Village, Mitra Bestari District, Tanjungpinang City, from September to November 2022, using three feed treatments with five replications. The feed treatments used were: a) Control feed (T0), b) Feed containing 22.5% Shrimp heads flour and 11% Rucah fish (T1), and c) Feed containing 11% Shrimp heads flour and 22.5% Rucah fish (T2). The parameters observed were egg production, egg weight, egg width, egg length, and egg index. Research data on egg production and weight were analyzed using a Completely Randomized Design (CRD), and a descriptive test for the egg index. It was found that the addition of Shrimp heads flour and Rucah fish in the Mojosari duck feed ration did not have any significant effects on the daily egg production and egg qualities. It is recommended to give Shrimp heads flour or Rucah fish at the level between 11.00-22.50% in the ration of the laying duck. [ABSTRACT FROM AUTHOR]
