This study was conducted to estimate heritabilities and genetic correlations of economic traits and body conformations in Korean Native Ogol fowl. The data analyzed were the record of 450 pullets bred from 150 dams and 20 sires of the fowl obtained from June 18, 1987 to February 6, 1989. The results of this study were summarized as follows ; The estimates of heritability for body weight, egg weight and shank length from combined variance components were relatively high, ranging from 0.415 to 0.558, while those for age at first egg, egg production and breast width were moderate, ranging from 0.301 to 0.334. For genetic correlations, body weights were negatively correlated with egg production, ranging from -0.552 to -0.309, while positive correlations were found between body weight and egg weight, ranging from 0.285 to 0.380. Also, egg production was negatively correlated with egg weight, ranging from -0.383 to -0.381. The shank length showed very high positive correlations with the body weights and age at 1st egg, ranging from 0.328 to 0.843. Hence the improvement in shank length will increase the body weight as well as the age at 1st egg.

국내 폐기물고형 연 료제품(SRF) 기준에는 음식폐기물이 포함될 수 없지만1 향후 다양한 연구를 통하여 건조된 음식폐기물도 SRF로 활용할 수 있는 가능성이 높다. 기존 음식 폐기물을 이용한 재활용 물질인 사료1 퇴비가 이용자로부터 기 피하는 경향이 있고, 특히 이들 재활용 물질을 사용한 가축, 채소 등에 대한 소비자의 불신 이 있다. 따라서 지속적으로 중가하는 음식폐 기 물 친환경 처리방법 발굴과 수요에 부합하는 정책을 시행할 필요성이 대두되고 있다. 건조한 음식폐기물을 다른 고체 연료와 혼합 연소하거나 직접 연소하기 위해서는 건조한 음식폐 기 물의 특성을 분석하는 것은 매우 중요하다. 본 연구는 건조한 음식 폐기 물 및 커피찌꺼기를 연소시키기 위한 연소로의 최적 설계를 위하여 공업분석 , 원소분석 , 발열량 측정과, TGA, DTG 분석 실험을 수행하여 음식폐기물 및 커피찌꺼기의 연료화를 위한 기 초적 인 연소 특성을 평가하고자 한다. 건조한 음식폐 기 물의 연소 특성을 규명하기 위하여 시료 4 종을 제조하여, 원소분석, 공업분석 , 발열량분석/ TGA분석 실험을 하였다 실험결과 연료비 (FC/VM)를 보면 0.16~0.20이고1 탄소/ 수소비 (C/H)는 7.4 ~ 7.7으로 나타났으며 저위발열량의 경우 커피찌꺼기의 발열량이 가장 높았다. SRF 의 Q 함량 기 준치인 2.0 wt.% 이하로 분석되었다. 음식폐기물의 TGA 분석결과는 연소반은 약 200t 에서 시작하여 약 500°C 에서 최고온도범 위에 이 르고, 약 900t 에서 연소반옹이 종료됨을 알 수 있다. 100~ 200°C 사이에서 수분이 중발되 며, 200~500°C 사이 에서 초기 휘발분, 탄소 및 잔류 휘발분의 방출, 연소가 이루어진다. 따라서 본 연구결과에 의하면 건조한 음식폐기물 및 커피찌꺼기는 SRF 기준을 충족하고 발열량도 상당히 높아 향후 고형연료로 사용이 가능할 것으로 사료된다.

In order to improve the efficiency of the main economic traits in layers the present selection index is based on body weight., age at first egg, egg production and. egg weight. But as the edible parts of the egg, the yolk and the albumin, are very important economic traits, this study was conducted to estimate the selection indices combining the latter traits with the former traits, and to examine the accuracy of the indices. The experiment were 351 Single Comb White Leghorns(S. C. W. Leghorn) and 326 Rhode Island Reds (R.I.Red), improved by the closed flock breeding system at the Daejeon Branch Station of the National Livestock Breeding Station. The egg compositions were checked a total of 6097 eggs. The data for each traits were collected and analysed until 500 days of age from March 1, 1979. The results obtained are summarized as follows: 1. The average body weights of the hens at first egg, 300 and 500 days of age were 1,409, 1,602 and 1,709g in the S.C.W. Leghorn and 1,965, 2,305 and 2,479g in the R.I.Red, respectively. The age at first egg of the S.C.W. Leghorn and the R.I.Red was 156 and 163 days, respectively. The number of eggs produced by the S.C.W. Leghorn and the R.I.Red to 300 and 500 days of age were 101.18, 214.39 and 101.05, 214.93, respectively. The egg weight at first egg, 300 and 500 days of age was 41.93, 57.65 and 60.33g in the S.C.W. Leghorn, and 41.82, 57.62 and 60.57g in the R.I.Red, respectively. The above results indicated that the coefficients of variation tended to fall in high heritable traits such as body weight and egg weight, and to rise in low heritable traits such as age at first egg and egg number. In the S.C.W. Leghorn, the albumin at first egg, 300 and 500 days of age was 28.67, 36.28 and 37.15g; the yolk weight was 9.21, 15.95 and 17.86g; and the egg shell weight was 4.04, 5.39 and 5.40g, respectively. In the R.I.Red, the albumin weight at first egg, 300 and 500 days of age was 28.95. 36.01 and 36.85g; the yolk weight was 9.46, 16.43 and 18.54g; and the egg shell weight was 3.66, 5.13 and 5.28g, respectively. The above results showed that the coefficients of variation tended to rise at the age of first egg and to fall at the age of 300 and 500 clays. 2. The heritability estimates in the S.C.W. Leghorn arid R.I.Red based oil the average variance of sires and darns, were 0.449∼0.535 and 0. 287∼0.451 for body weight, 0.153 and 0.132 for age at first egg; 0.303 and 0.119 for number of egg production, to 300 days; 0.278 and 0.117 for number of egg production to 500 days; 0.455∼0.851 and 0.390∼0.498 for egg weight from the age of first egg to 500 days; 0.535∼0.673 and 0.445∼0.577 for albumin weight; 0.278∼0.626 and 0.234∼0.448 for yolk weight; and 0.398∼0.661. and 0.229∼0.346 for egg shell weight, respectively. 3. The gentetic correlation coefficients of four economic traits, i. e. body weight, age at first egg, number of egg production and egg weight, were as' follows; In the S.C.W. Leghorn and the R.I.Red, the coefficients between body weight at different ages were 0.749∼0.852 and 0.608∼0.916; between body weight and age at first egg, 0.328∼0.426 and 0.186∼0.244; between body weight and number of egg production, -0.666∼-0.498 and-0.542∼-0.073; between body weight and egg weight. 0.384∼0.744 and 0.126∼0.612; between age at first egg and number of egg production,-0.639∼-0.452 and -0.754∼-0.320; between age at first egg and egg weight, 0.478∼0.705 and 0.021∼0.605; between number of egg production at 300 days of age and number of egg product ion at 500 days of age, 0.935 and 0.857; between number of egg production and egg weight, -0.623∼-0.355 and -0.861∼-0.327;, and between egg weight at different ages, 0.570∼0.971 and 0.450∼0.786, respectively. 4. The genetic correlation coefficients of egg composition were as follows. In the S.C.W. Leghorn and the R.I.Red, the coefficients between albumin weight were 0.612∼0.801 and 0.582∼0,713;, between albumin weight and yolk weight, 0.082∼0.399 and 0.142∼0.461; between albumin weight and egg shell weight, 0.674∼0.952 and 0.216∼0.546; between yolk weight, 0.530∼0.763 and 0.624∼0.787; between yolk weight and egg shell weight, 0.273∼0.771 and 0.122∼0.749; and between egg shell weight at different ages, 0.517∼0.936 and 0.512∼0.714, respectively. 5. The genetic correlation coefficients of the four economic traits and egg composition were as follow. In the S.C.W. Leghorn and the R.I.Red, the coefficients between body weight and albumin weight were 0.291∼0.651 and 0.299∼0.780; between body weight and yolk weight, 0.010∼0.589 and 0.198∼0.613; between body weight and egg shell weight, 0.527∼0.795 and 0.354∼0.564; between age at first egg and albumin weight, 0.401∼0.559 and 0.320∼0.520; between age at first egg and yolk weight, 0.508∼0.756 and 0.296∼0.534; between age at first egg and egg shell weight, 0.562∼0.774 and 0.365∼0.534; between number of egg production and albumin weight, -0.682∼-0.192 and -0.643∼-0.198; between number of egg production and yolk weight, -0.559∼-0.082, and -0.520∼-0.200; between number of egg production and egg shell weight, -0.66∼-0.282 and -0.501∼-0.175; between egg weight and albumin weight, 0.559∼0.977 and 0.328∼0.937; between egg weight and yolk weight, 0.176∼0.691 and 0.193∼0.879; and between egg weight and egg shell weight, 0.567∼0.994 and 0.154∼0.931, respectively. 6. In order improve the performance of the main economic traits in layers, the selection index (R_IH) I has been based on body weight, age at first egg, number of egg production and egg weight. But in this study, the selection indicies were estimated by combining yolk weight and/or albumin weight to the above after traits in order to increase the accuracy of selection. In the S.C.W. Leghorn the accuracy of the former selection index here after referred to as index 1 was 0.4699; 0.5165 when index I was combined with yolk weight, 0.4981 when combined with albumin weight, and 0.5270 when combined with both yolk and albumin weight at 300 days of age. The above results indicate that the composite indices were 9.91, 6.00 and 12.15% more accurate than index 1 alone, respectively. Index 1 at 500 days of age was 0.5136; 0.5331 when including yolk weight, 0.5296 when including albumin weight, and 0.5380 when including both yolk arid albumin weight. The above results indicate that the composite indices were 3.80, 3.12 and 4.75%more accurate than the index 1, respectively. In the H.I.R.Red, the accuracy of selection index 1 was 0.5134 ; 0.5481 when including yolk weight, 0.5383 when including albumin weight, and 0.5590 when including both yolk and albumin weight at 300 days of age. The above results indicate that the composite indices were 6.76, 4.85 and 8.88% more accurate than the index 1, respectively. Index 1 was 0.5203, 0.5368 when including yolk weight. 0.5203 when including albumin weight, and 0.5409 when including both yolk and albumin weight at 500 days of age. The results indicate that tire composite indices were 3.17, 0.00 and 4.00% more accurate than the index 1, respectively. 7 . The expected, genetic gains for each traits in the composite index including Yolk and albumin weight here after referred to as index 2 slightly decreased in comparison with the index 1, but the total economic value calculated for the several traits in the index 2 was higher than that calculated for the several traits in the index 1. The results obtained in this study suggest that the selection index 2 at 300 days is more accurate than selection index I , improving the accuracy of selection by between 9 and 12%.

尙炳贊 충남대학교 대학원 1975 論文集 Vol.5 No.-

These studies were carried out to investigate the properties of swine pepsin as milk-clotting enzyme and its utilization in the process of cheese making. The results were summarized as follows. 1) The optimum temperature for milk-clotting activity of swine pepsin was appeard at 40∼45℃, and the swine pepsin was completly inactivated at higher than 60℃. 2) The optimum pH for milk-clotting activity of swine pepsin was pH 4.0∼5.0, and the swine pepsin was comppletly inactivated at higher than pH 6.0 3) When the pepsin solution was treated by heating at 30∼70℃ for 10 minutes, pepsin activity was decreased seriously at 50℃, and it was completly inactivated at 60℃. 4) The higher keeping temperature and longer storaging period of the pepsin solution was showed the less milk-clotting activity. 5) Sodium propionate and Potassium sorbate were the most effective antiseptics for the preservation of the pepsin solution. 6) When the pepsin solution was exposed sunlight for 9hours, 26.5% of the enzyme activity was decreased. 7) Various animal serums were decreased the activity of the swine pepsin, especially swine serum of them was showed the most inactivity effect. 8) When 0.1㎖ of soy bean extract was added to 0.2㎖ of pepsin solution, 83% of pepsin activity was decreased. 9) Ammonium sulfate of the various saturated salt solutions was showed the most inactivating effect, but heavy metal salts were showed the activating effects. 10) The higher concentration of CaCl₂ in milk showed the higher milk-clotting activity of the pepsin. When 0.02% of CaCl₂ was added to milk, 43.4% of the pepsin activity was increased. 11) The curd weight per milk weight obtained 10.80% from swine pepsin, and 11.40% from rennet. But the difference between these was no significant.
