Abstract
Apparent nutrient digestibility and metabolizable
energy of selected grains by different types of pheasants was assessed. Wheat,
sorghum and maize were fed in mash to four different types (n=72) adult male
pheasants e.g., Cheer, Silver, Ring necked and Golden
for eight days. Birds from each type (n=18) were replicated (n=9)
with 2 birds per replicate in metabolic cages (n=36) for feces collection.
Different nutrients and gross energy in grains and feces were measured and
digestibility coefficients and apparent metabolizable energy were determined.
Dry matter
digestibility was maximum for maize (0.801) followed by wheat and sorghum,
respectively.
Organic matter was significantly more digestible in maize fed cheer pheasants
(0.833) to wheat (0.802) and sorghum (0.786). Nitrogen retained in maize fed
birds was higher 12.24 and 23.32% to wheat and sorghum, respectively. Fat from
wheat was less digestible ranged from 0.668 to 0.687 in different type of
pheasants. Digestibility of fibre was higher in Cheer type (0.627) and lower in
Ring Necked pheasants (0.60). Higher calcium digestibility (0.528) was noted in
maize fed Golden pheasants and lowest for sorghum (0.477) fed Ring Necked
pheasants. Digestibility coefficient of phosphorus in maize (0.531) and wheat
(0.515) was higher fed to Cheer pheasants. Apparent metabolizable energy of
maize was significantly greater (13.4 MJ/kg) compared to wheat and sorghum. It
can be deduced that both cereal and pheasant type influence nutrient digestibility and metabolizable energy
differently. More accuracy is needed in digestibility values in formulating
ration for pheasants from different sources.
