강상열,최진호,백동훈,신원집 한국가금학회 1983 韓國家禽學會誌 Vol.10 No.2

밀감피 건조분말의 부러일러에 대한 사료가치를 규명하기 위하여 밀감 가공공장에서 박피된 밀감피를 수거한 후 일광건조 및 분쇄하여 밀감피 건조분말을 제조하였다. 또한 밀감피 건조분말의 일반성분, 아미노산 함양 및 광물질 함양을 분석하였다. 부로일러 전용종인 Maniker 초생추 암컷 192수를 12수씩 16개군으로 나누어 밀기울을 대치한 밀감피 건조분말의 수준을 0, 2. 4 및 6%의 4개 처리 4반복으로 완전임의배치하여 6주간 사양시험을 실시하였으며 사양시험 종료시 전 공시추에 대하여 개체별로 정강이 착색도를 조사하였는 바 그 결과를 요약하면 다음과 같다. 1. 부로일러의 증체량, 사료섭취량 및 사료효율에 있어서 밀감피 건조분말의 급여수준에 따른 통계적인 유의차는 없었다. 2: 부로일러의 정강이 착색도는 밀감피 건조분말의 첨가수준이 증가함에 따라 증가하였다(P<0.05). 이상의 시험결과에 의하면 부로일러사료에 밀기울을 대치하여 밀감피 건조분말을 6% 수준까지 사용할 수 있음을 알 수 있었다. A study was conducted to investigate possibility of utilizing dried citrus peel (DCP) as an ingridient of broiler diets. Fresh citrus peels were collected from a citrus processing plant, and were sun-dried and ground. Both chemical analyses and a feeding trial were carried out. DCP was analyzed for proximate nutrients, amino acids and some minerals. In the feeding trial, a total of 192 day-old female broiler chicks of Manor strain was divided into 16 groups of 12 birds each. Each group was fed one of the 4 different levels(0, 2, 4 and 6%) of DCP replacing an equivalent amount of wheat bran in the diet with 4 replications for 6 weeks. Body weight gain, feed intake and feed efficiency of broilers fed different levels of DCP showed no significant differences among treatments. Immediately after termination of the feeding trial, cach bird was examined for shank color using Roche's Egg Yolk Color Fan. Shank color index of birds increased consistently (P<0.05) as the level of DCP fed increased, indicating that DCP can be used as a source of pigments. It was concluded from the results that DCP could be used up to 6% in place of wheat bran in broiler diets without adverse effects.

崔辰浩,李化錫,康商烈,申源執 전북대학교 농업과학기술연구소 1983 農大論文集 Vol.14 No.-

자돈의 성장과정에서 사료에 첨가하는 성장 촋진제인 carbadox를 salinomycin으로 대치할 수 있는지 가능성을 검토하고자 체중 약 25kg내외의 거세한 숫컷 56두와 암컷 56두를 공시하여 78일간 사양 시험을 실시하였다. 전시험 기간을 starter (22일간), grower(28일간) 및 finisher (28일간)기간으로 구분하여 전지작 약품을 투여하지 않는 대조구(T₁)와 starter-grower-finisher 기간에 각각 carbadox 50ppmㅡsalinomycin 25 ppm-salinomycin 25 ppm을 투여한 T₂, carbadox 50 ppm,- salinomycin 25ppm을 투여한 T₃ 및 carbadox와 대등한 약품인 olaquindox 50ppm-olaquindox 25 ppm-olaquindox 25 ppm을 투여한 T₄의 4개 처리를 두고 각각 증체량, 사료섭취량, 사료효율을 측정한 결과는 다음과 같다. 1. 증체량은 T₁이 두당 60.8kg인데 비하여 T₂,T₃,T₄가 각각 63.0, 61.9, 62.2kg 으로 각각 3.6, 1.8, 2.3%의 증가를 보였다. 2. 사료 섭취량은 T₁이 두당 188.7kg을 섭취한 데 비하여 T₂,T₃,T₄가 각각 190.1ㅡ 190.2, 193.3kg으로 약품을 투여한 구의 돼지가 무투약구의 돼지보다 약간 더 많은 사료를 섭취하였다. 3. 사료 효율은 T₁,T₂,T₃,T₄, 각각 3.12, 3.02, 3.08 및 3.11 로 carbados-salinomycin을 섭취한 돼지의 사료효율이 다소 개선되었다. 4. 전체적으로 통계적인 유의성은 없었으나 약품을 투여한 구에서 무투약구에 비하여 일율적으로 증체량과 사료 효율이 다소 개선되었으며 grower 기간이나 finisher 기간에 salinomycin은 효과적으로 carbadoxn를 대치할 수 있었다.

톱밥우사의 우상바닥처리 형태와 톱밥의 효율적 이용을 구명하기 위하여 PVC lightsheet지붕에 우상바닥처리별로 톱밥 10cm+콘크리트바닥, 톱밥 30cm+콘크리트바닥, 톱밥 30cm+바닥에 각각 경산우 6두(1두당 톱밥우상 16.5㎥)씩을 공시하여 시험한 결과 톱밥우상내 온도는 톱밥 30cm+흙바닥 처리가 가장 높았고, 수분증발량은 톱밥 10cm+콘크리트바닥에서 가장 많았다. 톱밥우사에서의 사료섭취 장소 및 톱밥우상의 분뇨배설은 단위면적당 톱밥우상에서는 91% 사료섭취장소에서는 9%가 배설되었으며, 착유우의 1일 분뇨 배설량은(착유시간 제외) 분 31.45kg, 뇨 10.7kg, 계 42.23kg이었으며 우분의 수분함량은 83.96%이었다. 공시완료한 분뇨가 혼합된 톱밥의 성분함량은 우분비율이 많은 톱밥 10cm+콘크리트바닥에서 무기물 성분이 가장 많이 함유되었으며, 흙바닥 처리구의 토양 중 NO$_3$-N함량이 허용한계 (10ppm이하)이상으로 검출되어 수질오염 가능성이 나타났다. 톱밥우상의 처리방법별 년간 유지비용은 톱밥 10cm+콘크리트바닥 처리가 년간 가장 적게 소요되었으며, 톱밥의 효율적 이용, 톱밥 교체시 노력절감 등으로 보아 가장 유리한 것으로 나타났다. This study was carried out to investigate the effect of depth of sawdust bedding and ground material in dairy cattle barn. Treatment included the concrete floor with a 10cm or 30cm sawdust and the earth floor with a 30cm sawdust. Eighteen cows were assigned to 3 pens with 16.5㎥/head bedding area. The results obtained were as follows : 1. The temperature of sawdust bed was highest in the earth floor with 30cm sawdust, and the moisture content of sawdust bed was highest in the concrete floor with 10cm sawdust bed. 2. Cows defecate feces 9.2, 8.7 and 9.3 times a day in 10cm sawdust on concrete floor(10S+C), 30cm sawdust on concrete floor(30S+C) and 30cm sawdust on non concrete floor(30S+ NC) respectively. In average, they excreta 9.1 times/day(85.8%) in the sawdust beds and 1.5 times/day(14.2%) in the feeding alley. 3. The ratio of daily water amount deposited vapor to total water amount deposited in sawdust beds was 74.0%, 61.5% and 47.1% in 10S+C, 30S+C and 30S+NC respectively. 4. N.P.K contents in the sawdust beds were higher for 10S+C compared with other treatments. 5. When 30cm of sawdust was applied on the earth ground NO$_3$-N contents in the sawdust bed was 37.7, 14.1 and 15.0ppm in depth of 30, 60 and 90cm under the ground, respectively, indicating some possibility of water pollution.

This study was carried out to investigate the effect of sawdust bedding barn on manure handing, management labour and physiological aspect of dairy cows, and then to establish the criteria on the optimum utilization method of sawdust bedding barn. 46 tie stall barns and 49 sawdust bedding barns were surveyed to cmopare the milk productivity between two different barns, and also 5 tie stall barns, 15 sawdust bedding barns and 1 rice hull bedding barn were selected to study the utilization situation of sawdust barn in Kyung-Ki province area. The major results obtained were as follows; 1. The roof material of sawdust barn were consisted of 66% vinyl house, 23% PVC light and 11% slate and galvanum coated tin. Most of the floor structure was earth ground with the rate of the approximately 82%. 2. The average occupied area of sawdust bed per cow was 15.2 $m^2$, depth that 30 cm and the utilization period was 12 months. 3. Milk Yield was significantly higher at sawdust barn than at tie stall barn(P<0.01). Bacterial and somatic cell count in raw milk were less at the sawdust barn than in tie stall barn. However, there was not significance difference between two barns. 4. The labour hour needed to cow management in the sawdust barn was approximately 48% of that of tie stall barn. 5. The temperature and moisture content measured in sawdust bed were closely affected by seasonal ambient temperature. The skin and hair of cow were much cleaner at the PVC light roofed sawdust barn than any other roof materials. 6. The additives used for improving of fermentation did not show any effect on temperature and moisture content in sawdust bed. When the ambient temperature was $30.4^{\circ}C$, the surface temperature of measured 1 cm above the sawdust bed was $12.2^{\circ}C$ lower and the temperature of 100 cm above the sawdust bed was $2.4^{\circ}C lower under shading net facility than that of vinyl roofed one.7. The hoof length of miking cow was 7.95 cm in tie stall and 9.19 cm in sawdust barn with high significance (P<0.01). And disease occurence such as mastitis and foot-rot tended to decrease in the sawdust barn. 8. The number of total bacteria and coliform bacteria were less in the sawdust bed compared with earth ground resting area. And a parasite strongyloides papillosus was detected but without any infected cow. 9. The nitrate($NO_3N$) content in non-roofed earth ground resting area and earth ground under the sawdust bed was likely to pollute the ground water. 10. In economic point of view, rice hull bedding barn was the cheapest among different systems. And in the sawdust bedding barn PVC light + slate roofed barn was most desirable, and vinyl roofed one the least.
