RESULTS

Chemical composition of DCP

Chemical analysis revealed that DCP contained 90.63% DM, 94.57% OM, 6.32%

CP, 20.68% NDF, 14.32% ADF and 5.43% ash (Table 4.1).

Nutrient intake

Various levels of DCP in diets of Lohi lambs had non-significant effect (P>0.05)
on nutrient intake (Table 4.2). The DM intake was 1.27, 1.28, 1.29 and 1.30 kg/day in lambs

fed diets containing 10, 20, 30 and 40% DCP. It was slightly higher in lambs fed VHDCP
diet (containing 40% DCP) than other treatments (Table 4.2). There was a non-significant

difference (P>0.05) in OM intake among all treatments. However, slight increase in OM

intake was observed numerically as the level of DCP was increased in the diet. It was 1.17,
1.18, 1.20 and 1.20 kg/day in lambs fed LDCP, MDCP, HDCP and VHDCP diets,

respectively (Table 4.2).

The CP intake was not significantly different (P>0.05) among various levels of DCP

in diets. It was 0.18, 0.18, 0.19 and 0.19 kg/day in lambs fed LDCP, MDCP, HDCP and

VHDCP diets, respectively (Table 4.2). A non-significant difference (P>0.05) on NDF
intake was observed in lambs fed various levels of DCP in diets (Table 4.2). The NDF

intake was found 0.23, 0.24, 0.26 and 0.26 kg/day in lambs fed 10, 20, 30 and 40% DCP.
Results revealed that intake of ADF was not significantly affected (P>0.05) by varying

levels of DCP. The ADF intake was 0.18, 0.19, 0.20 and 0.20 kg/day in lambs fed LDCP,
MDCP, HDCP and VHDCP diets, respectively (Table 4.2).

Digestibility

Various levels of DCP fed to Lohi lambs had non-significant effect on digestibility.
The DMD was 69.60, 69.57, 68.18 and 67.98% when the lambs were fed 10, 20, 30 and

40% DCP in diets, respectively (Table 4.3). The OM digestibility was non-significant
(P>0.05) among different treatments of DCP. However, a slight decrease in OM
