Perbandingan Produksi dan Nilai Ekonomis Plasma Nutfah Itik Lokal Sumatera Barat Dalam Upaya Konservasi

The influence of genetic type of local duck (Pitalah and Bayang) on growth performance, carcass traits, cholesterol of blood and meat was assessed in 200 one-day-old male duck, for 12 weeks of age. They were given iso calorie and isoprotein of diets, depend on the growth phase (Stater and Grower). 20 ducks from each breed were randomly chosen for blood serum and meat cholesterol analysis. The data were analysed by t-test. The result showed that Pitalah had growth performance better than Bayang (P<0,05), and Feed Consumption Ratio (FCR) followed the same trend. Pitalah ducks were heavier (1466.46 g) than Bayang duck (1410.62 g). The carcass percentage of Pitalah also better (P<0,05) 8,32% than Bayang. The income over feed and duck of duck at the age of 8 weeks is more profitable than at the age of 12 weeks with the decreasing of IOFD 68% on Pitalah duck and 78% on Bayang duck.Then, it is also found that Pitalah blood and meat cholesterol characteristics almost better than Bayang (P<0,05). In conclusion, Pitalah duck as germplasm from West Sumatera has better potential to develop as meat production for Conservation than Bayang.
