한우 거세우에 대한 Cu의 급여효과를 규명하기 위하여 농후사료중의 Cu 수준을 사료 kg당 7 mg, 12 mg 또는 17 mg의 3개 처리구에 각 5두씩 계 15두를 공시하여 435일간 비육시험을 실시한 결과는 다음과 같다. 일당증체량은 비육전기, 비육중기 및 비육후기 전기간에 걸처 Cu 7mg, 12mg 또는 17 mg 급여구간에 차이가 없었고 비육 전기간 평균에서도 각각 0.75, 0.76, 0.75kg으로서 처리구간에 유의적인 차이는 없었다. 사료섭취량은 처리구간에 비육전기에는 9.21-9.64 kg, 비육중기에는 9.53-9.75kg, 비육후기에는 10.09-10.93 kg으로 비육시기별로 큰 차이가 없었고 비육전기간에는 9.86-10.21 kg으로 처리구간에 큰 차이가 없었다. 사료효율은 비육전기에는 11.08-11.72, 비육중기에는 13.60-14.34, 비육후기에는 14.01- 15.20으로 처리구간에 큰 차이는 없었고 비육전기간에서도 13.31-13.99로 처리간에 차이가 없었다. 한우 거세우에게 Cu를 급여하였을 때 도체율은 58.4-59.2%로 처리구간에 차이는 없었다. 육량등급중에서 등지방두께는 8.2-10.4 mm로 처리구간에 큰 차이는 없었다. 배최장근단면적은 대조구와 12 mg 및 17 mg 급여구가 각각 78.4, 82.2 및 79.8 $cm^2$로 처리구간에 차이는 없었다. 육량지수는 68.10-68.91로서 처리구간에 차이는 없었다. 육량등급은 모두 B 등급으로서 처리구간에 차이가 없었다. 육질등급에서 가장 중요한 요인인 근내지방도는 Cu 7mg, 12mg 또는 17mg 급여구가 각각 3.6, 4.8 및 4.2로서 12 mg 첨가구가 약간 높게 나타났으나 처리구간에 유의적인 차이는 없었다. 육색, 지방색, 조직감 그리고 성숙도 등에서도 Cu 첨가구간에 큰 차이가 없었다. 육질등급은 처리구간에 모두 1등급을 받았고 Cu 수준간에 차이가 없었다. 경제성분석 결과 조수익은 대조구에서는 두당 2,577,483원, Cu 12mg 급여구는 2,920,432원, Cu 17mg 급여구는 2,653,227원으로써 Cu 12 mg 급여구가 7mg 급여구에 비해 13.3%, 17 mg 급여구에 비해 10.1%가 높게 나타났다. 이상과 같은 결과들을 종합해 볼 때 한우 거세우에게 농후사료 중에 Cu를 사료 kg당 7, 12 또는 17 mg을 넣어 주었을 때 성장, 육량 및 육질등급에서는 처리간에 차이가 없었으나 경제성에서는 12 mg 급여구가 조수익이 높았다. This experiment was conducted to determine the effects of dietary copper levels on performance, carcass characteristics, and economical analysis in Hanwoo steers. Fifteen Hanwoo steers weighing about 300kg were randomly allotted into one of three treatments. The three treatments consisted of Control(7mg Cu/kg feed), TI(12mg Cu/kg feed) and TII(17mg Cu/kg feed). Copper was formulated with concentrate from copper sulfate($CuSO_4$) and animals were fed the diets supplemented with copper from 300kg untill about 630 kg of body weight. Dietary copper levels did not affect daily weight gain, feed intake and feed efficiency during the whole feeding period. Dressing percentage, rib eye area and backfat thickness were not different between animals fed the diets supplemented with copper. Animals fed the diets supplemented with copper received the same B grade in yield grade. Animals fed the diets supplemented with copper received same marbling score. Beef color, fat color, texture and maturity were not affected by Cu supplementation in diet. Animals received the same first grade between treatments in quality grade. Animals fed the diet supplemented with 12mg of copper per kg diet was higher in profit by 13.3% than animals fed the control diet. According to these results, it may be concluded that performance, yield and quality grade were not affected by the Cu levels of 7 to 17mg per kg feed but crude income was enhanced when Hanwoo steers were fed the diet containing 12mg Cu/kg feed.

This experiment was carried out to investigate the dietary protein and energy requirements of egg type growing chickens of Single Comb White Leghorn. Three levels of dietary energy (2900, 2800, 2700㎉/㎏, ME) were fed and each energy level was combined with one of the three protein levels of 17, 15, 13%. The results obtained were as follows. 1. In the energy levels, body weight gain and feed efficiency improved significantly (p$lt;0.01) higher in the 2900㎉ and 2800 ㎉ energy levels than in the 2700 ㎉ energy level. However, there were no significant differences between 2800 ㎉ and 2900 ㎉ energy levels. Feed intake showed no significant differences among energy levels. 2. In the protein levels, body gain and feed efficiency improved significantly (p$lt;0.01) higher in the 17% and 15% protein levels than in the 13% protein level. However, there were no significant differences between 17% and 15% protein levels. Feed intake was not significantly affected by protein levels. In the growing chickens, body weight gain and feed efficiency were more affected by protein levels than by energy levels. Body gain (Y₁) and feed efficiency (Y₂) of growing chickens were associated in a quadratic mode with the protein levels (X) of ration. Regression equations, Y₁ = -186.77 + 88.15X - 2.733X² Y₂ = 10.864 - 0.6888X + 0.0204X² indicated that the maximum body weight gain and feed efficiency occurred when the protein level was 15 %. 3. Energy (ME) intake per bird per day ranged from 147㎉ to 157㎉ and was not affected by protein levels but was slightly lower in the low energy levels. protein intake per bird per day ranged from 7.07g to 9.15g and was not affected by energy levels but was slightly lower in the low protein levels. According to the above results, it is concluded that protein level of 15% and energy levels of 2800㎉ to 2900㎉ would be adequate for optimal growth of growing chickens.

This experiment was carried out to investigate the dietary protein and energy requirements of egg type growing chickens of Single Comb White Leghorn. Three energy levels (2900, 2800, 2700 ㎉/㎏, ME) were fed and each energy level was combined with one of the three protein levels of 17, 15, 13%. Digestion trial and slaughter analysis were conducted. The results obtained were as follows. 1. Utilization of dry matter and crude fat decreased numerically with decreasing levels of~energy but no significant differences were found among energy levels. Crude protein utilization increased progressively as the energy levels decreased without any statistical significance. Utilization of carbohydrate and energy improved significantly (p$lt;0.01) with increasing levels of energy. Utilization of carbohydrate (Y₁) and energy (Y₂) of growing chickens was found to be associated in a linear mode with the energy levels (X) of nation. A regression equation Y₁ = 37.389 + 0.01573X Y₂ = 19.002 + 0.01973X indicated that the maximum utilization of carbohydrate and energy occurred when the energy level was 2900 ㎉/㎏. 2. Utilization of dry matter, crude protein, carbohydrate and energy showed no significant differences among protein levels. Utilization of crude fat was significantly (p$lt;0.05) higher in the 17% protein diet than in diets of 13 and 15% protein. 3. Body composition of growing chickens was not greatly affected by the dietary energy levels. Body protein content of growing chickens decreased and body fat content increased numerically as the dietary protein levels decreased. Ash content was not affected by the dietary protein and energy levels. According to the above results, it is concluded that 15% protein and 2900 ㎉/㎏ of metabolizable energy would be adequate for optimal utilization of nutrients in growing chickens.

This experiment was carried out to investigate the nutritive value of brewery`s activated sludge on the performance and nutrients utilization by egg type chicken of Babcock fed the different levels of sludge. Brewery`s activated sludge was substituted at 3, 6, 9 and 12% levels for soybean oil meal in experimental ration. The results obtained were as follows. 1) Body gain of chicken fed the different levels of sludge was decreased in proportion to increasing level of sludge. However, no statistical differences were found out between treatments. 2) Diet intake of chicken fed the different levels of sludge was significantly (P$lt;0.05) increased as the supplementation level of sludge in ration increased. 3) Feed conversion rate of chicken fed the different levels of sludge was high in proportion to increasing level of sludge in ration. However, there were no significant differences between treatments. 4) Utilization of dry matter of chicken fed the different levels of sludge was decreased as the level of sludge in ration increased. However, no statistical differences were found out between treatments. 5) Utilization of crude protein of chicken fed the different levels of sludge was significantly(P$lt;0.01) increased as the level of sludge was higher. Utilization of crude protein of control treatment and of sludge 3 treatment was higher than that of other treatments. 6) Utilization of crude ash of chicken fed the different levels of sludge was significantly(P$lt;0.05) decreased in proportion to increasing level of sludge in ration. 7) Utilization of NFE of chicken fed the different levels of sludge was slightly decreased in proportion to increasing level of sludge in ration. However, no statistical differences were found out between treatment. Therefore according to this experiment, it may be concluded that brewery`s activated sludge can be supplemented with chicken ration( for egg type, Babcock) by 6 - 9%.
