THE EFFECT OF ENERGY LEVEL OF FEEDING ON DAILY GAIN, BLOOD GLUCOSE AND UREA ON MADURA CATTLE
Abstract: This study was aimed
to evaluate the effect of dietary energy level on daily gain of Madura cattle
and their blood metabolites (glucose and blood urea). Twelve (12) male Madura
cattle aged at 2 years old, 156.27+6.92 kg (CV 4.43%) of body weight were used
in this study which was assigned to completely randomized design for three
feeding treatments (low, middle and high energy contents) and four
replications. The daily gain was measured for 90 days, while the blood
metabolites were measured at the middle of experiment. Results showed that dietary
energy levels did not affect (P>0.05) average daily gain, dry matter intake,
dry matter digestibility, energy intake and feed conversion ratio. Blood
glucose and blood urea concentration were ranged at 67-75 and 35-50 mg/dL,
respectively, while feed energy efficiency reached 0.145 MJ/g ADG. In
conclusion, high-level energy could not provide better performance in Madura
cattle because of a limitation factor on the DMI.
