LAYING PERFORMANCE AND EGG QUALITY TRAITS OF ITIK PINAS (IP)-KAYUMANGGI (Anas platyrhynchos) UNDER INTENSIVE AND SEMI-INTENSIVE FARMING SYSTEM

Abstract

This study was conducted to assess the laying performance, egg quality, fertility rate, and egg classification of Itik PINAS (IP)-Kayumanggi under the intensive and semi-intensive farming system. A total of 240 heads of IP-Kayumanggi were divided into two treatments with 15 replications per treatment. Each pen consists of one drake and seven ducks. Laying performance was compared between treatments from 29 to 42 weeks of age using t-test. Results demonstrated that IP-Kayumanggi ducks under semi-intensive farming systems have significantly higher livability rate (99.57%), average egg weight (70.76 g), average albumen weight (41.69 g) and darker yolk color. The fertility rate at 10th and 15th days of candling were significantly higher in semi-intensive (87.74% and 82.38%) than intensive farming (77.64% and 67.37%). Extra small and small sizes of eggs are mainly produced under intensive systems while more medium and large sizes eggs are under semi-intensive systems. Therefore, this study suggests the production advantages of IP-Kayumanggi under semi-intensive farming system.
