This research was conducted to compare and analyze the effect of the space allowance on the productivity, behavior, and blood properties of Hanwoo in order to achieve the status of advanced country for the animal husbandry in accordance with global trends, and with the target of animal welfare production through the practice of environmentally friendly animal husbandry. Fattening cows (352kg) of an average of 43 months in age and with growing steers (225kg) aged six months were tested with two replications upon categorizing the animals into control group (8m2/heads) and treatment group (4m2/heads). Feeding was executed according to the prescription in the Hanwoo feeding management. The growth performances (BW, ADG, and FCR) were significantly improved in cow fattening as space allowance was narrower. Similar results were obtained from the growing steers. The behavioral characteristics of lying and walking were significantly higher in the control group (p<0.05), while standing was found significantly higher (p<0.01) in the treatment group. The lying duration did not show significant difference in the fattening cows. Meanwhile, walking time was significantly longer (p<0.01) in the control group among fattening cows whereas standing duration was significantly higher (p<0.05) in the treatment group. As for properties of blood component, the cortisol value was significantly higher (p<0.05) in the treatment group for the fattened cows.The experiment results imply that the space of 8 m2 / head would be adequate in the production of fattening cows and growing steers based on growth performances, behavioral characteristics, and blood component, and considering the space allowance per head in the pen. The results could be utilized as basic data for environmentally friendly and welfare type Hanwoo production system in the future.
