Quality of Duck Eggs Maintained Using a Different Maintenance System in the Malang Raya Area

This study aims to examine the effect of nomadic intensive, semi-intensive and extensive maintenance systems on the physical quality of duck eggs. Ducks used 36 - 50 weeks old were fed with a composition of rations from smallholder farmers. The research design used was non-experimental research using survey methods. Surveys were conducted on 5 farmers from Greater Malang. Sampling in this study was conducted using a purposive sampling method. Samples from selected summits were divided into 3 maintenance systems, namely intensive, semi-intensive maintenance systems and extensive. Measurements of egg physical quality include egg weight, eggshell weight, and thickness of the g. The data obtained were then compared to an average using the ANNOVA test . The results showed that the ducks were reared using the system maintenance intensive to produce eggs with a better physical quality than the ducks are reared using intensive maintenance system. This can be seen from the egg yolk color score and the yolk index. Egg weight, eggshell weight, eggshell thickness, egg white index and Haugh unit provide the same quality between intensive, semiintensive and extensive maintenance systems
