감귤부산물의 사료화에 관한 연구 6 . 육성비육돈에 대한 건조감귤부산물의 사료가치에 관한 연구
양승주(Seung Ju Yang),정창조(Chang Cho Choung) 한국축산학회 1987 한국축산학회지 Vol.29 No.6
Twnty-four weaners (average weight, 31 Kg) were fed for 73 days on a ration which included 0%, 5%, 10% and 15% dried citrus peel. Daily body weight gain was T_0 ; 0.804Kg, T₁ ; 0.859Kg, T₂ ; 0.874Kg, T₃ ; 0.794 Kg and daily feed intake was T_0; 2.64Kg, T₁ ; 2.85Kg, T₂ ; 2.93Kg and T₃ ; 2.74Kg. The feed intake increased up to the 10% substitution level but decreased at the 15% level. This tencency was more pronounced during the fattening than growing period. The increase in dried peel substitution levels reduced backfat thickness; increased carcass length; and widens loin eye area and generally improves carcass quality. Utilization of DM and NFE was highest in the 10% dried peel substitution level and protein was highest in the 5% substitution level. With increasing substitution levels the digestibility of crude fiber improved. From the data collected on body weight, feed intake, digestibility and carcass quality it is recommended that 10% dried citrus peel substitution is the optimum level. However under certain conditions it might be possible to increases the substitution level up to 15%.

감귤부산물 silage 의 수분함량 및 첨가물의 첨가가 품질과 DM 소화율에 미치는 영향

To utilize citrus byproducts for animal feeds two different silages were made 1) using citrus peel 2) using citrus pulp mixture. The experimental design included 12 treatments, six for citrus peel silage and six for citrus pulp mixture silage, then treatments were allocated according to sun-drying and urea, barley straw and NaOH treated straw additions. Chemical composition, pH, organic acid and NBDMD were examined and treatments compared. Sun-drying (3 days) citrus waste reduced the moisture content by 6-10%. Addition of barley straw reduced the moisture content of the two silages by 4-8%. The content of protein was increased 1.25-1.63% by the urea addition of 0.6% of the silage weight. Crude fiber was increased 4-5% by the addition of 8-10% barley straw, and also increased 7-8% by the addition of 16-21% barley straw. But the change in the other ingredients by the addition of barley straw was not found, except NFE wait decreased. The pH of the non-treated silage was 3.4-4.7, and that was increased by the addition of urea and NaOH. The content of organic acid was changed by the addition of urea as follows: (1) the content of lactic acid was lowered, and (2) L.A./T.A. was decreased. But by the addition of 8-10% barley straw by the silage weight, the content or lactic acid was increased and the standard of L.A./T.A. was heightened. On the contrary, it showed the tendency of decreasing in the case of the addition of 16-20% barley straw. The range of NBDMD of raw citrus byproducts was 79.64-81.11%. That of the citrus byproducts silage was increased by the addition of urea (84.16-88.08%), and decreased by the addition of barley straw (62.4-73.16%). The addition of urea and alkali treated straw significantly increased digestibility especially in pulp mixture silage but had the reverse effect on silage quality.

Holstein 착유우에 대한 감귤가공부산물 Silage 급여가 유량 및 유조성에 미치는 영향
정창조,양승주 제주대학교 농과대학 제주도축산문제연구소 1986 畜産論叢 Vol.1 No.1
Citrus waste silage, urea added silage and urea plus wheat bran sitage were fed to eight milking cows for 140 days. Control cows were grazed and fed silage freerations. Two cows in each treatment were allowed to graze for 4-6 hours daily, fed dairy concentrate according to milk yields and offered 10kg of one kind of citrus waste silage. Intake of citrus waste was higher in urea added silage (T_(2)) and urea plus weat bran silage(T_(3)) than in control silage (T_(0)) and T_1 silage where cows were fed citrus waste silage without additions. It was noted that the cows in T_(2) and T_(3) gave higher milk yields and that peak periods were extented. The butterfat percentage increased slightly when cows were fed citrus waste silage with addition of urea and wheat brans. It was observed that the palatability of citrus waste silage was excellent and gave rise to increased milk production and improved milk quality.

감귤부산물의 사료화에 관한 연구 : -Ⅳ. 산란계에 대한 건조감귤부산물의 사료가치-
정창조,양승주 제주대학교 1985 논문집 Vol.20 No.-
As a follow up to recent local broiler experiments further studies were carried out using dried citrus peel and pulp at different substitution levels in layer's rations. 150 nineteenweeks-old Warren layers were used in the present experiment over a period of twenty two weeks. The experimental design used included five treatments; TO (control). T1 (5% dried citrus peel substitu-tion), T2 (10% Ditto), T3 (15% Ditto), T4 (5% dried citrus segment and pulp). Egg production rate (78.9%-82.5%) decreased significantly in T3 but no statistically significant differences were found between other treatments. Egg weights (59.6-62.1g) decreased according to substitution level. Daily feed intake (127.0-129.8g) decreased significantly in T3 and was higher in T 1 and T2. There were no differences in palatability up to the 10% substitution level. Feed efficiency (2.5-2 7) also showed a simillar tendency to that of the feed intake. There were no singificant differences in daily weight gains between treatments but a slightly higher weight gain was observed in treatment 3 and 4. Yolk colour intensity increased and percentage of cracked and soft eggs dropped when substitution levels rose. The proportion of yolk weight to whole egg weight, however, decreased. Crude protein utilization decreased according to the increasement of substitution (especially in T3) but there were no differences in NFE utilization between treatments. It is suggested, based on these results, that the substitution of dried citrus waste improves egg yolk colour but results in a decrease in egg weight. It would appear that 10% is the optimum substitution level of dried citrus waste in layers rations.
