        노폐한우 비육에 대한 옥수수 silage , 대맥silage , 호맥silage 의 사료가치에 관한 연구

        김형호,정연후 ( Hyoung Ho Kim,Yuen Hoo Chung ) 한국축산학회 1983 한국축산학회지 Vol.25 No.3

        Fifteen Korean Native cow (356 ㎏ body weight, over 8 years old) were used in this feeding trial for 50 days to study the effect of corn yellow ripe stage silage, rye heading stage silage and barley yellow ripe stage silage on the fattening performance of the Korean Native cow. The results obtained are as follows: 1. It was found that the average daily weight gain for corn silage, rye silage and barley silage were 1.15 ㎏, 0.53 ㎏ and 0.81 ㎏, respectively. A significant difference (p$lt;0.05) was appeared between corn silage and rye silage. 2 The daily TDN intakes of corn silage, rye silage and barley silage group were 6.91 ㎏, 5.35 ㎏ and 5.85 ㎏, respectively. The least TDN intake was appeared in the rye silage among the groups. 3. The TDN requirement per ㎏ gain of corn silage, rye silage and barley silage group were 6.04 ㎏, 7.74 ㎏ and 7.20 ㎏, respectively. The result was indicated more feed for rye silage group. In conclusion, it might be recommended using barley silage as a roughage for fattening in the area of rice paddy where is a limiting corn silage production.

        노폐한우의 비육기간이 비육능력과 도체에 미치는 영향

        김형호,정연후 한국축산학회 1984 한국축산학회지 Vol.26 No.8

        The experiment was carried out to investigate the effects of duration on fattening performance and carcass characteristics of Korean native cows over 8 years old. Fifteen over 8 years old were alloted for 3 different length of period (120, 150 and 180 days.). The longer the fattening days, the less the average daily gain obtained and the more the feed requirement were observed. The carcass rate was increased as the fattening period were prolonged, but the carcass characteristics and carcass grade were not significantly different, although more fats were deposited around kidney and pelvic. It is concluded that the optimum fattening period of the Korean native cows over 8 years old were 120 days on 500㎏ of body weight.
