Abstract

The study was conducted to determine the effects of varying lysine to calorie ratio(3.3, 3.5, 3.7,3.9 and 4.1 digestible Lysine at 2800 kcal ME/kg) on growth performance of Philippine Mallard ducks from 0 to 6 weeks of age. A total of 150 improved Philippine Mallard day-old-ducklings were randomly assigned to 5 dietary treatments with three replicate pens and 10 ducks per replicate pen. Body weight, weight gain, and feed intake were measured weekly to calculate the feed conversion ratio. Increasing lysine-to-calorie ratio had no significant effect on the overall body weight gain, feed intake, and feed conversion efficiency of Philippine mallard ducks from 0 to 6 weeks. However, specifically at week 2, an increasing linear trend on average body weight gain and decreasing linear trend for FCR have been observed when lysine to calorie ratio was increased from 3.3 to 4.1. Based on the overall performance of the ducks from 0 to 6 weeks of age, it can be concluded that digestible lysine to calorie ratio of 3.3 was enough to satisfy the requirements of the ducks at this stage. Further increase in lysine level, while holding the dietary energy level constant at 2800 kcal ME/kg, did not improve the performance of the ducks.
