Determine of level curude protein for Hoa Lan duck
A study to determined crude protein requirements for Hoa Lan duck at difference age satges. The completely randomized design (CRD) with 1 factor (crude protein in the diet) x 3 treatments x 3 replications. The dietary nutrient content and feeding regimens were the same between treatment groups exception of crude protein levels. A total of 1.800 1-day-old ducklings (360 males + 1.440 females) period 0-8 weeks of age; 1.350 ducks (270 males + 1.080 females) period 9-20 weeks of age and 1.080 ducks (180 males + 900 females) prieod 21-72 weeks of age. The result that using ME and crude protein levels for Hoa Lan duck period 0-8: 9-12 and 21-72 age weeks were 2.900; 2,750, and 2,700 kcal/kg and 20; 15 and 17%; crude protein, respectively. They were not significant in production yield and feed conversion ratio/10 eggs, but they had tended to improve 2,37% when applying this nutritional diet in treatment 2 as compared to treatment1
