Three animals were offered randomly either moth chara (Phaseolus aconi
tifolius) alone (NS) or with 500 g barley (SC) or 150 g oil (SO) for 1
month before switching over to different diet according to 3 x 3 lati
n-square design. The energy to CP ratio (kcal/g; ME/CP ratio) was 17.7
4 in NS. It increased to 18.25 and 18.9 in SC and SO respectively. Mul
tiple correlation analysis indicated negative correlation (R = -0.723)
between glucose and ME/CP ratio. ?he change in weight(g/100 kg W/day;
Delta-W) had high relationship with glucose (r = -0.816), alanine tra
nsaminase (r = -0.605), calcium (r = 0.599) and serum protein (-0.497)
. The ME/CP ratio, dry matter in take and body weight together could e
xplain 86.7% variability in Delta-W. A suitable energy supplement is r
equired during winter.
