EFFECT OF LEVEL OF CONCENTRATE FEEDING LEVEL ON EFFICIENCY OF EATING BEHAVIOUR ON ONGOLE CROSSBRED CATTLE
Abstract: Eight bulls of
Ongole Crossbred (OC) cattle with initial body weight (BW) of 297 + 26 kg (CV
=8.75%) fed rice straw treated with urine (RU) (ad libitum) were divided into
two groups (each fourheads) to determine the effect of concentrate feeding
level on efficiency of eating behavior. The cattlewas given concentrate feeding
composed of beer cake and rice bran to make 14% crude protein at 1%and at 2% BW
for RUC1 and RUC2 group, respectively. Eating behavior was measured for 3x24
hoursand was performed twice at weeks 2 and 6 of the study. Data obtained were
analyzed by t-test. Theresults showed that the level of concentrate feeding
affected the intake of urinated rice straw (P<0.01)and daily BWGain
(P<0.05), but the effect was not found (P>0.05) on DMI, length time for
eating(196.5 vs. 221.5 min/d), length time for rumination (351.0 vs. 449.4
min/d), efficiency of eating time(37.21 vs. 37.67 gDM/min) and efficiency
rumination time (21.43 vs. 18.50 gDM/min). This researchshowed that concentrate
feeding at 2% BW did not alter the efficiency of eating time and
ruminationcompared to 1% BW, although able to improve BWG of OC cattle.
