Abstract

Calcium is an essential mineral for eggshell formation and muscle contraction, and a deficiency of it can lead to poor egg quality and lower egg production in laying ducks. This study aims to determine the effect of giving the mineral calcium in a ration containing shrimp head flour and Bilis fish head on the laying performance and quality of hatching eggs of Mojosari ducks. A total of 105 female Mojosari ducks and 15 male Mojosari ducks, aged 78 weeks, were randomly divided into 15 flocks (each flock consisted of 7 females and 1 male duck). There were three kinds of treatment, namely P1 (ratio of prawn head meal and anchovies meal 2:1 + 1% mineral), P2 (comparison of prawn head meal and anchovies meal 1:2 + 1% mineral)., P3 (control, without mineral). The results showed that giving calcium minerals to feed containing shrimp head meal and Bilis fish head meal had no effect (P>0.05) on the performance of laying hens such as feed consumption, egg production, egg weight. Likewise, calcium mineral supplementation did not make a significant difference to fertility and hatchability, but the reduction in egg weight was significantly different (P<0.05). Numerically, P2 tends to have a large egg production (53.77%) compared to P1 (51.07%) and control (51.07%). Based on this research, it can be concluded that the provision of feed based on shrimp head meal and anchovies meal can be done without the addition of calcium minerals.
