To investigate the protein sparring effect of ㎗-methionine and ℓ-lysine on the egg type pullet ration, this experiment with a total of 288 Hisex strain pullets was carried out for a period of 8 weeks (15-22 weeks), 8 treatments of (1) control, CP l4%, (2) basal, CP 12%, (3) basal + lysine 0.1 %, (4) basal + lysine 0.2 %, (5) basal + methio;nine 0.1 %g (6) basal + methionine 0.2%, (7) basal + lysine 0.1 % + methionine 0.1 %, (8) basal + lysine 0.2% + methionine 0.2% with 3 replicates were employed in this experiment. Metabolism trial was conducted at the end of feeding trial. The obtained results were summarized as follows; 1. Body gain was higher in the basal treatment than in other treatments. However, there were no significant differences on body weight gain among treatments. 2. Birds fed the basal ration consumed less feed than birds fed the control ration and lysine and methionine supplemented ration. However, no significant differences were found on diet intake among treatments. Feed efficiency was more improved in the lysine + methionine 0.2% treatment than in other treatments. However, there were no significant differences on feed efficiency among treatments. 3. In the nutrients utilization, utilization of dry matter and crude protein was higher in the lysine 0.1 % + methionine 0.1 % and lysine 0.2% + methionine 0.2% treatments than in other treatments. 4. In the economical analysis, feed cost required for ㎏ body gain was lowest in the basal treatment and next in the lysine 0.2% and lysine 0.2% + methionine 0.2% treatments. Therefore, based on the results of this experiment, it is concluded that basal treatment (CP 12%) was most profitable among treatments during the period of pullet (I 5-22 weeks) and next in order of lysine 0.2%, lysine 0.2% + methionine 0.2% and lysine 0.1% + methionine 0.1 % treatments, respectively.

To investigate the protein sparing effect of DL-methionine and L-lysin on the laying hen ration, the present experiment with a total of 288 hens (Hi-sex commercial hens) was carried out for a period of 14 weeks (23-36 weeks). In this experiment 8 treatments ((1) control, CP 16%; (2) basal, CP 14% (3)basal +L-lysine 0.1% ; (4) basal+L-lysine 0.2% ; (5) basal+DL-methionine 0.1 % ; (6) basal+DL-methionine 0.2%; (7) basal+L-lysine 0.1%+DL-methionine 0.1 %; and (8) basal+L-lysine 0.2%+DL-methionine 0.2%) were employed. Metabolism trial was conducted at the end of feeling trial. The results obtained are summarized as follows; 1. The highest egg production was obtained from the group of basal+L-lysine 0.2%+DL-methionine 0.2% and the lowest from the group of basil +L-lysine 0.2%. But no statistically significant difference was found among all the treatments. 2. The heaviest egg weight was obtained from the group of basal+L-lysine 0.2%+DL-methionine 0.2% and the lightest was obtained from basal+L-lysine 0. 1%. But no significant difference was found among all the treatments. 3 . In feed intake, significant (p$lt;0.05) differences were found among treatment groups. Higher feed consumptions were generally resulted from the groups supplemented with L-lysine and/or DL-methionine. 4. Best, feed efficiency was obtained from control group, and the worst from the group of basal+L-lysine 0.1%+DL-methionine 0.1%. But no significant difference was found among all the treatments. 5. Nutrient utilization was not affected by supplementation with L-lysine and/or DL-methionine. 6. Feed cost per Kg egg mass production was in order of basal, basal +L-lysine 0.1%, basal+L-methionine 0.1%, basal+L-lysine 0.2%+DL-methionine 0.2%, control, basal+L-lysine 0.2%, basal+L-lysine 0.1%+DLmethionine 0.1%, and basal+DL-methionine 0.2%. Therefore, based on the results of this experiment, it is concluded that supplementation of L-Lysine and DL -Methionine at the level of 0.2% respectively with the basal ration(14% protein) would be able to spare 2% dietary protein.

본 연구는 요양보호사의 직무환경이 서비스 질에 미치는 영향관계에서 요양보호사의 직무환경 요양보호사의 서비스 질을 제공하는 실천적 현장에서 활용하였다. 또한 요양보호사의 서비스 질에 대한 차별화된 정책과 지원방안을 제시하는데 목적을 두었다. 응답자의 인구통계학적 특성에 따른 변인의 차이를 살펴보면, 학력에 있어서 ‘대학원 졸업’이 직무환경과 직업전문성, 사회적지지, 서비스 질에 모두 영향을 미치고 있었다. 반면, 종교와는 크게 영향을 미치지 못한 것으로 나타났다. 요양보호사의 직무환경인 대인관계, 인사, 조직 순으로 서비스 질에 정(+)적인 영향을 미치고, 인사관련 요인의 경우 서비스 질에 영향을 미치지 않는 것으로 나타났다. This study was used in the practical field of providing caregivers' service quality in relation to the effect of caregivers' job environment on service quality. In addition, the purpose of this study was to suggest differentiated policies and support measures for caregivers' service quality. Looking at the differences in variables according to the demographic characteristics of the respondents, in terms of academic background, 'graduation from graduate school' had an effect on all of the job environment, occupational expertise, social support, and service quality. On the other hand, religion did not appear to have a significant effect. It was found that the job environment of caregivers, interpersonal relationships, personnel, and organization, in order, had a positive (+) effect on service quality, and personnel-related factors had no effect on service quality.

수수의 옥수수대찬 및 메티오닌 , 라이신의 첨가가 육계의 능력에 미치는 영향

김광석,한인규,하종규,곽종형 ( K . S . Kim,I . K . Han,J . K . Ha,C . H . Kwack ) 한국축산학회 1986 한국축산학회지 Vol.28 No.11

This experiment was conducted to examine the effect of substituting sorghum grain for corn, and methionine and lysine supplementation on the chick performances. Two hundred and eighty male broiler chicks were divided into 28 groups of 10 birds. Substitution levels of sorghum grain for corn were 0% (diet 1), 40%(diet 2 and 3), 60%(diet 4 and 5), and 80%(diet 6 and 7) of corn. The basis of supplementing limiting amino acids (methionine and lysine) was to meet the level of chick`s requirements. There were no significant differences in weight gain among groups. Adding sorghum grain to the diet increased (p$lt;0.05) feed intake. However, no differences in feed intake were observed among sorghum grain fed groups. Increased feed intake by chicks fed sorghum grains may have been caused by lower energy density of sorghum grain. Feed efficiency of diet 1 (no sorghum diet) was significantly (p$lt;0.05) better than those of other dietary groups, which probably can be explained by the lower energy density in sorghum grain. The effect of amino acid supplementation to the sorghum diets was not prominent in the present study.

김광현(K . H . Kim),곽종형(C . H . Kwack) 한국축산학회 1990 한국축산학회지 Vol.32 No.12

This study was conducted to determine the optimum level of DL-methionine for finishing pigs fed 10% CP corn-soy diet fortified with 0.30% L-lysine and 0.09% L-threonine. One hundred and twenty finishing pigs (L × W × D: 56.6kg BW) were randomly allotted to 4 supplemental levels of DL-methionine treatments(0, 0.035, 0.07 and 0.105%) for 63 days per replicate. respectively. A metabolic trial was conducted with 12 pigs for 5 days after the feeding trial. Results obtained were summarized as follows; 1. There was significant difference(p$lt;.05) among treatments, the best value of daily weight gain and feed conversion were recorded with the 0.07% treatment. Daily feed intake were better in 0.035% treatment than the other treatments. 2. Although there was no significant differences among treatments, the highest values of crude protein digestibility, TDN and nitrogen retention were recorded with the 0.07% treatment. However, the methionine availability value(89.28%) of 0.07% treatment was significantly(p$lt;.05) higher than those of the other treatments. 3. The free S-containing amino acid level of plasma tended to increase as dietary level of methionine increased. However, the plasma urea-N level was the lowest in 0.07% treatment. 4. The total non-sulfar free essential amino acid level of plasma was lowest in 0.07% treatment and showed tendency to increase as the methionine level increased to 0.105%. It could be concluded that the optimum level of DL-methionine supplementation for finishing pigs fed 10% CP corn soy diet is 0.07%, resulting in 0.40% S-containing amino acids in the diet.
