Abstract
Two hundred fifty eight Hanwoo steers were used in a completely randomized design experiment to determine the effects of ad libitum or restricted feeding of concentrates on body weight(BW) gain, feed intake, blood metabolites and hematological parameters. Steers were assigned at 6 months of age to feeding groups of ad libitum(T1) or restricted(T2) by 18 months of age. Steers in both groups were fed ad libitum from 19 months of age. The restrictive feeding levels were 1.2-1.5% of BW for the growing period and 1.7-1.8% of BW for the early fattening period. Average daily gains were significantly higher in T1 than in T2 from 10 to 14 months of age, but were significantly higher in T2 than in T1 from 20 to 24 months of age(p<0.05). Total dry matter intake(DMI) was higher in T1 than in T2 at 10, 12 and 16 months of age(p<0.05). Total DMI of T2 was higher than that of T1 at 22 months of age(p<0.05). Feed conversions were significantly lower in T2 than in T1 from 20 to 30 months of age(p<0.05). Blood albumin concentrations were significantly higher in T2 than in T1 at 12, 14, 16 and 18 months of age. Blood triglyceride concentrations were significantly higher in T1 than in T2 at 14 and 16 months of age(p<0.05). Blood inorganic phosphorus concentrations were significantly higher in T2 compared with T1 at 8, 10, 16 and 22 months of age(p<0.05). Mean corpuscular volume and mean corpuscular hemoglobin were significantly lower in T2 than in T1 from 8 to 12 months of age(p<0.05), but those were significantly higher in T2 than T1 from 10 months to 12 months of age(p<0.05). Present results may indicate that the restricted feeding for the growing period does not show adverse effects on body weight gain with better feed conversion for the following late fattening period.
