To search for the interaction of three antirachitogenic nutrients, calcium, phosphorus and vitamin D₃, two experiments were conducted using a total of 512 commercially hatched broiler chicks of Hisex Hybro strain. One experiment, arranged in 2 x 2 x 3 factorial design were used to study the growing performance of the chicks, supplemented with two levels (0.9, 0.45%) of calcium, two levels (0.7, 0.35%) of phosphorus and three levels (0, 200, 400 IU/㎏ diet) of vitamin D₃. Another experiment was designed to study the changes in serum calcium and phosphorus contents with or without vitamin D₃ dose. A 2 x 2 x 2 factorial arrangement with 4 replications of chicks was employed with two levels (0 and 0.66 g per day) of calcium, two levels (0 and 0.51 g per day) of phosphorus and two levels (0, and 30 IU per day) of vitamin D₃. The result obtained are summarized as follows. 1. There were significant effects on body weight gain with single administration of calcium, phosphorus and vitamin D₃ and also showed marked effects on growth rate with calcium x phosphorus interaction and calcium x vitamin D₃ interaction. However, present evidence indicated that the effect of phosphorus x vitamin D₃ interaction and calcium x phosphours x vitamin D₃ interaction on growing performance were not significant. 2. Feed intake were significantly (p $lt; 0.01) influenced by the single administration of calcium and vitamin D₃ and by the interaction of calcium x phosphorus, calcium x vitamin D, phosphorus x. vitamin D and calcium x phosphorus x vitamin D. There was not a significant effect of single phosphorus administration on feed intake. 3. It was found that feed conversion were also greatly influenced by the silagle supplementation of calcium, phosphorus and vitamin D₃. And also influenced by calcium x phosphorus, calcium vitamin D₃, phosphorus x vatimin D₃ and calcium x phosphorus x vitamin D₃ interaction. 4. Data revealed that there was no marked improvement in growing performance by in; creasing vitamin D₃ level to 400 IU/㎏ to the chicks, previously fed no or low vitamin D₃. But there was a great improvement on feed conversion with increasing level of vitamin D₃ to the chicks. 5. No significant differences were found in nutrient utilizabilities among treatments. Protein utilizabilities were gradually increased with increasing level of vitamin D₃ in optimum calcium fed groups and vice versa in low calcium received group. 6. Analytical indicated that raising the level of dietary vitamin D₃ led to increase in tibia ash content and calcium and phosphorus content of tibia. Tibia ash contents were greater in optimum calcium fed groups than in suboptimum calcium treated groups. However, there was no difference in tibia ash content between optimum and suboptimum phosphorus fed groups. 7. Supplementing no vitamin D₃ led to high mortality percent during experimentation. There was also significant difference in mortality between low and optimum calcium fed groups and not between dietary phosphorus level. 8. Present data showed that serum calcium level was, increased in contrast with the serum phosphorus level, decreased after vitamin D₃ administration. This tendency was evident at 12 hours after dose of vitamin D₃. When the optimum calcium was offered, the serum phosphorus contents was decreased after vitamin D₃ administration but showed no changes in no prior vitamin D₃ administration. It could be concluded that the supplementation of vitamin D₃ to the broiler chick diet is indispensable for the normal growth, especially in suboptimum level of calcium and phosphorus diet. It was also apparent that increasing vitamin D₃ above 200 IU per ㎏ diet did not show additional effect on the growing performance of chicks. It would be necessary to undertake more-detailed study for the time course information of serum calcium and phosphorus change after vitamin D₃ dose.

맥주박을 이용한 알코올 발효사료의 최적 발효조건 규명

김창혁,박병기,오상집,성경일,김현숙,홍병주,신종서,Kim, C.H.,Park, B.K.,Ohh, S.J.,Sung, K.I.,Kim, H.S.,Hong, B.J.,Shin, J.S. 한국축산학회 2005 한국축산학회지 Vol.47 No.4

본 시험은 맥주박의 알코올 발효가 발효특성 및 사료의 영양적 가치에 미치는 영향을 검토하기 위하여 실시하였다. 본 시험에 이용한 시험사료는 맥주박과 파쇄 옥수수를 50:50(풍건상태)의 비율로 혼합하여 혐기 발효에 의하여 발효사료를 제조하였다. 발효 조건은 당밀 첨가 수준(0, 2 및 5%), yeast 첨가 수준(0, 0.1, 0.5, 1.0 및 2.0%) 및 발효 온도(4, 10, 30, 40 및 50$^{\circ}C$)에 따른 변화를 검토하였으며, 각 조건에 의한 알코올 함량, live yeast cell number (LYCN) 및 pH 변화를 조사하였다. 당밀 첨가에 따른 알코올 함량은 첨가수준이 증가할수록 높게 생성되었다. 발효 24시간 동안에 yeast 0.1, 0.5, 1.0 및 2.0% 첨가에 따른 알코올 함량은 각각 1.9, 2.4, 3.1 및 3.1%로 나타나, yeast 첨가수준 1% 까지는 yeast의 첨가수준이 증가할수록 시험사료중의 알코올 생성량도 비례적으로 증가하였으나(P<0.05), yeast 첨가수준 1.0 이상에서는 일정한 양의 알코올 이 생성되었다. 발효 초기의 LYCN은 yeast 첨가수준이 높을수록 높게 나타났으나(P<0.05), 발효 48시간 후의 LNCN은 0.1% 이하에서는 유의적으로 낮게 나타났다(P<0.05). 발효 온도에 따른 알코올 생성량은 발효 온도 30 및 40$^{\circ}C$에서 유의적으로 높은 결과를 보였으며(P<0.05), 30$^{\circ}C$와 40$^{\circ}C$ 간의 알코올 생성량은 30$^{\circ}C$에서 높은 경향이었다. 발효 온도에 따른 pH는 발효 온도가 낮을수록 발효 24시간까지 급격히 감소하는 것으로 나타났다(P<0.05). 이상의 결과로 미루어 맥주박의 사료적 가치를 높이기 위해 yeast의 첨가량, 당밀(발효기질), 발효온도 및 발효시간 등의 요인을 고려하였을 경우, 본 시험의 조건하에서 원활한 알코올 발효와 발효사료의 품질을 향상시키기 위한 적정 발효조건은 당밀 5%와 yeast 1%를 첨가하여 30$^{\circ}C$에서 24시간 동안 발효시키는 것이 가장 바람직한 것으로 나타났다. To determine the optimum fermentation condition, the 50:50 feed mixture of both crushed corn and wet brewer’s grain were anaerobically fermented at various conditions. Three supplementation levels(0, 2%, and 5%) of molasses, five supplementation levels(0, 0.1%, 0.5%, 1.0%, and 2.0%) of yeast and five different incubation temperatures(4$^{\circ}C$, 10$^{\circ}C$, 30$^{\circ}C$, 40$^{\circ}C$ and 50$^{\circ}C$) were tested to determine the optimum fermentation conditions. During fermentation, alcohol concentration, live yeast cell number (LYCN) and pH values of the mixture were analyzed. Alcohol concentrations of the fermented feed mixtures were proportionally increased with increasing level of molasses supplementation. After 24hr fermentation, alcohol concentrations at 0.1%, 0.5%, 1.0% and 2.0% of yeast supplementation was 1.9%, 2.4%, 3.1% and 3.1%, respectively. These results indicate a proportional increase of alcohol concentration with the increasing supplementation of yeast (P<0.05) up to 1%, thereafter showing plateau at 2% supplementation. LYCN was relatively high with more than 0.5% yeast supplementation, whereas the value was significantly low(P<0.05) at 0.1% yeast supplementation. Alcohol production was significantly higher at 30$^{\circ}C$ and 40$^{\circ}C$ than other incubation temperatures (P<0.05), with the highest concentration at 30$^{\circ}C$. pH was rapidly decreased until 24 hours of incubation with steeper decrease at lower temperatures(P<0.05). Based on there results, optimum fermentation conditions for the alcoholic-fermented feed production could be achieved with 5% supplementation of molasses, 1% supplementation of yeast, and 24hr long incubation at 30$^{\circ}C$.

본 연구는 사료에 서양고추냉이 분말 0.03%, 팽이버섯폐배지 0.5% 및 서양고추냉이 분말 0.03%와 팽이버섯폐배지 0.5%의 혼합제를 사료에 각각 첨가한 후 비육돈에 급여하여 분뇨에서 발생되는 악취물질의 농도변화를 조사하였다. 1. 분뇨의 단쇄지방산 농도를 측정한 결과 초산, 프로피온산, 부티르산 및 이성체지방산의 농도는 처리구간에 차이가 없었다(p>0.05). 2. 분뇨의 페놀, p-크레졸 및 이들을 합한 페놀류 농도는 처리구간에 차이가 없었다(p>0.05). 그러나 인돌 농도는 고추냉이 처리구에서 낮았으며(p<0.05), 스카톨 농도는 대조구와 고추냉이구에서 가장 높았고, 고추냉이와 버섯폐배지의 혼합구에서 가장 낮았으며, 버섯폐배지구는 중간이었다(p<0.05). 인돌류 농도는 고추냉이와 버섯폐배지의 혼합구에서 가장 낮았다(p<0.05). This study was to performed to investigate the effect of horseradish powder and mushroom waste in fattening pig diet on odorous compound concentration from slurry. Twenty fattening boars [Landrace${\times}$Yorkshire) ${\times}$ Duroc] weighing an average body weight of $78.4{\pm}8.88$ kg were randomly assigned to one of 4 treatments (control, horseradish 0.03%, mushroom waste 0.5%, and combination; horseradish 0.03% + mushroom waste 0.5%). This experiment was a randomized complete block (RCB) design using 5 pigs per treatment with 1 pig per metabolizable cage. Pigs were fed experimental diet (amount proportional to 3% of their body weight) twice a day (09:00 and 16:00) for 7 d after having 14 d adaptation period. Experimental diets were mixed with water by 1:2.5 v/v. Odorous compounds in slurry including acetate, propionate, butyrate, trans fatty acid isomers were not different (P>0.05) among treatments. There was no difference (P>0.05) in the levels of phenol compounds including phenol and p-cresol in slurry among treatments. Concentration of indole was lower (P<0.05) in horseradish group compared with others. Skatole level was highest in control and horseradish group, middle in mushroom waste group, and lowest in combination group (P<0.05). Concentration of indole compounds was lowest (P<0.05) in combination group. Data from our current study suggest that indole compounds in slurry can be reduced by administrating pigs with 0.03% horseradish powder and 0.5% mushroom waste in their diet.

This experiment was conducted to compare the utilizability of locally produced tricalcium phosphate (TCP) with that of imported dicalcium phosphate (DCP), tricalcium phosphate, bone meal with a total of 350 White Leghorn laying hens of 48 weeks old. The results obtained during 16 weeks of experimental period are summarized as follows. 1. Different sources of calcium and phosphorus had no apparent effects on the egg production rate, egg mass and feed efficiency when a large amount of fish meal at the level of 8 % was used in the laying rations. 2. It was found that there was no difference in the egg shell thickness, the contents of crude ash, calcium and phosphorous of egg shell when various sources of phosphate supplements were used. 3. No difference was also found in the nutrient utilizability among experimental diet groups. 4. There were little differences in body weight gain of hens in all the treatments, however, the mortality was slightly higher for the control group than the groups received inorganic phosphorus through various phosphate supplements. The results obtained from present experiments showed that there were no differences in the egg production rate, egg mass, egg shell quality, feed efficiency and mortality by the various phosphate supplements when fed with a large a mount of fish meal (8%). Present evidence indicated that the quality of locally produced TCP in comparable to that of imported TCP or DCP.

In order to compare the nutritive values of locally produced tricalcium phosphate (TCP) with that of imported tricalcium phosphate(TCP), dicalcium phosphate(DCP) and that of bone meal when no fish meal was supplied, a total of 350 White Leghorn laying hens of 65 weeks old were fed for a period of 5 weeks. The results obtained are summarized as follows. 1. No differences were found in egg production rate, egg mass arid feed efficiency between various phosphate supplements, however, the control group receive no fish meal showed considerable decrease in egg weight, production rate and egg mass. 2. There was no difference in egg shell thickness, and content of Ca and P among various phosphate supplements, however, egg-shell thickness of control group was slightly thinner than that of inorganic phosphate fed group. The contents of Ca and P of egg-shell for the control group were lower than other groups. 3. The crude ash content of tibia was slightly decreased for both bone meal group and the control group, however, there were no differences between tricalcium phosphate groups and dicalcium phosphate group in the content of crude ash of tibia. The calcium and phosphorous contents of tibia of hens fed various phosphate supplements were higher than those of control group. 4. No difference were obtained in nutrient utilizability among various sources of phosphorus fed groups, However utilizability of dry matter and crude protein were slightly decreased for the control group. 5. The decrease in body weight during experimental period was observed for all then groups, especially was notable for the control group. The mortality observed during experimental period was not different among calcium phosphate groups, however, was slightly higher for the control group than the other groups. The results obtained from the present experiment showed that there were no differences in the nutritive value of locally produced TCP when was compared with imported DCP or TCP. It was also suggested that supplement of inorganic phosphorus for layers maybe very important when no fish meal was used in the laying rations.

한인규,오상집,하종규,김춘수 ( In K . Han,Sang J . Ohh,Jong K . Ha,Chun S . Kim ) 한국축산학회 1978 한국축산학회지 Vol.20 No.2

Two experiments were conducted to study the effects of use of Feedrectar on the growing performances of young pigs (Expt. I) and broiler chicks (Expt. II). In the Experiment I, 200 crossbred baby pigs weighing approximately 11㎏ of body weight mere used in five treatments of Feednectar 0%, Feednectar 0.05%, Feednectar 0.1%, sucrose 2% and a palatability-testing groups during 4 weeks of experimental period. In the Experiment II, a total of 270 broiler chicks of Shaver strain were employed in three treatments consisted of 0%, 0.05%, 0.1% of Feednectar for a period of 8 weeks. The results obtained are summarized as follows: 1. It was found that the body weight gain of young pigs (9.4%) and broiler chicks (5.6%) was significantly (P$lt;0.05) improved when the Feednectar was added is the rations of these experimental animals at the level of 0.1%. 2. The amount of feed consumed by the experimental pigs and chicks was also consider ably (P$lt;0.05) increased as the level of Feednectar in the diets increased. 3. Present data indicated that the feed efficiency of animals fed Feednectar was also improved, although no statistical significance was found between treatments except 0.1%, Feedneetar fed broilers that showed significant difference at the level of 5%. 4. It was apparent that the addition of Feednectar at the level of 0.1% would be recommendable for better growing performances of early weaned pigs and broiler chicks. 5. Palatability test conducted by young pigs revealed that the addition of either Feednectar or sugar could improve the palatability of experimental diets. 6. Shark color of broiler chicks was slightly improved by the use of Feednectar, although the significant difference was not found. 7. It was found that the experimental chicks fed Feednectar utilized the dry matter, crude protein, crude fat and carbohydrate in the diet more efficiently than control group. 8. Protein loss in the rations of pigs and broilers was alway less for Feednectar added diet than control diet during the storage period.
