“…Coefficient of retention of calcium was 40.5%, which was somewhat lower than 42.8–47.7% reported in Golden pheasant [Sultan et al, ]. Based upon the endogenous losses and coefficient of retention it was estimated that an LAP would require 328 mg Ca/kg BW 0.75 /d and a diet containing 0.75% Ca would be adequate to meet maintenance requirement of calcium in LAP, which is within the range of 0.53–0.93% recommended for Ring‐necked pheasants [Scott et al, ; Hinkson et al, ]. Results of this experiment indicate that Ca requirement of LAP could be similar to that of ring‐necked pheasants.…”

Effect of feeding graded levels of crude protein on nutrient utilization and feather growth in Lady Amherst's pheasants

et al. 2015

In order to find out the optimum level of crude protein (CP) in the diet of captive Lady Amherst's pheasants (LAP) on molt, 18 male birds were randomly distributed into three groups of six each in an experiment based on completely randomized block design. The CP content of the diets of birds in groups I, II, and III was 13.4, 16.5, and 19.1%, respectively. Intake and apparent balance of nitrogen increased linearly (P < 0.001) as CP content of the diet increased. Intake and utilization of energy, calcium, and phosphorous were similar among groups. Body mass change and growth rate of feathers were significantly (P < 0.01) lower in group I as compared to groups II and III. There was a positive co-relationship between ME intake and change in body weight (R(2) = 0.89, F = 126.4, P < 0.001). Regression analysis indicates that LAP can maintain body mass when ME supply is 122.2 Kcal/kg BW(0.75)/d. Linear relationships between intake and apparent retention of N, Ca, and P as expressed on mg/kg BW(0.75)/d were all significant. Apparent nitrogen retention, and mean feather growth rate was lower in birds fed diet containing 13.4% CP. Feeding of the diets containing 16.5% CP resulted in improved retention of nitrogen, and mean feather growth rate. Further increase in dietary concentration of CP to 19.1% showed no further improvement. It was concluded that a diet containing 16.5% CP would be optimum for Lady Amherst's pheasants during molt.
