  • Lytic activities of the egg white lysozyme from Korea-native Ogol fowl against the alkalophilic and thermophilic Bacillus sp. TA-11 were investigated and compared. Lytic activity of the Ogol fowl lysozyme for Bacillus sp. TA-11 was the highest for the cell of post-logarithm phase and optimum concentration of the lysozyme was 0.25%, Optimum reaction pH and temperature were 4.5 and 35$^{\circ}C$, respectively. Lytic activity of egg white lysozyme from fowl for Bacillus sp. TA-11 was the highest for the cell of stationary phase and optimum concentration of the lysozyme was 0.5%. Optimum reaction pH and temperature were 5.5 and 4$0^{\circ}C$, respectively.

  • This study was carried out to investigate meat production ability of special poultry(Ogol fowl, pheasant and mallard). The results obtained Were summarized as follows ; 1. On the average live weight in male and female of Ogol fowl and mallard were 1,304.0~1,311.8g, 1,013.0~1,138.8g, respectively. The live weight of pheasant was lighter than that of Ogol fowl and mallard. The ratio of carcass to live weight in pheasant, Ogol fowl and mallard were 70.9~72.2%, 66.9~68.2% and 65.4~65.9%, respectively. 2. On the edible giblets ratio to live weight, the that of mallard was the highest(6.3%), while the that of Ogol fowl was the lowest(4.7~4.8%) in each individual poultry. 3. On the cut-up parts ratio to carcass weight, the neck(6.7~8.3%) and back(16.1~18.0%) ratio of pheasant were lower than that of Ogol fowl and mallard, but the neck(11.1~13.3%), wings(14.6~16.2%) and back(23.6~5.2%) ratio of mallard were higher than the others. 4. On the ratio of meat to breast and legs parts, the yield of breast meat was higher than that of legs meat of all poultries. In mallard, the skin ratio on both parts(17.6~22.9%) was higher than the others, while the bone ratio of pheasant and Ogol fowl(15.6~20.6) was higher than that of mallard.

  • In order to obtain the basic information for new food product development from pheasant, wild duck(chhungdung), and Ogol fowl, which are called as special poultry, general components,fatty acid amino acid and minerals composition were analyzed. 1). The general compositions were 71.2-74.1% of water, 23.3-26.4% of protein, 1.0-2.4% fat, and 1.1-1.4% of ash in the pheasant, 73.8-76.4% of water, 18.6-19.6% of protein, 2.7-6.8% of fat, and 0.8-1.6% of ash in the wild duck, and 71.4-72.3% of water, 20.8-22.7% of protein, 1.9-6.3% of fat, and 1.0-1.2% of ash in the Ogol fowl, repectively. 2).In the pheasant and wild duck meat, the composition of unsaturated and saturated fatty acid were 60-64%,36-40%, respectively, and olec, palmitic, linolec, and stearic acid were most abundant in this order. But, in Ogol fowl, 72-76% and 24-28% were belong to the unsaturated fatty acid, respectively. 3). Amino acid contents in its order of relative amount were glutamic acid, alanine, aspatic acid, and glycine for the pheasant, glutamic acid, glycine, alanine, and aspatic acid for the wild duck, and lysine, glutamic acid, and aspatic acid for the Ogol fowl, repectively. 4).The mineral composition in the pheasant and wild duck were potassium, phosphorus, sodium, magnesium, and calcium, but in the Ogol fowl, potassium, sodium, magnesium, phosphorus, calcium were the most abundant in this order, repectively.

  • To elucidate the effect of egg white lysozyme from Ogol fowl on the preservation of milks, fishcurd and sausage, changes of pH, volatile base nitrogen content and viable cell count were investigated during the storage periods at $20^{\circ}C$, $30^{\circ}C$ and $37^{\circ}C$ after the addition of lysozyme in each foods. Volatile base nitrogen count of raw milk as marker of spoilage was lowest(63 mg%) in 0.05% lysozyme addition lot which was stored at $20^{\circ}C$ for 2 days, and its preservation effect by lysozyme at $30^{\circ}C$ was enhanced with addition of glycine(0.1%). Preservation effect by lysozyme in commercial milk at $37^{\circ}C$ and in fishcurd at $5^{\circ}C$ and $20^{\circ}C$ were also good, and when sausage was stored at $5^{\circ}C$ after treatment of lysozyme instead of sorbic acid, its preservation effect was acceptable.

  • Meat color, general composition and Putting force of Korean native Ogol fowls were investigated. These results were as follows. The contents of moisture and crude protein were higher in breast than in thigh. However, the contents of crude fat and fiber were higher in thigh than in breast. There were no significant differences in these contents with weeks of age. L, a, b value of Korean native Ogol fowls were showed grey by Hunter Color Solid. Cutting force of thigh was greater than that of breast. Also, cutting force of male was greater than that of female. Those cutting forces were increased as weeks of age increased.

  • This study was conducted to estimate heritabilities and genetic correlations on economic traits in Korean Native Ogol Fowl. The data analysis were the record of 450 pullets produced from 150 dams and 20 sires of Korean Native Ogol Fowl raised at Chungnam National University from June 18, 1987 to April 6, 1989. The results obtained are summarized as follows ; 1. The average body weights at 8 and 24 weeks,300 and 500 days of age were 514.54, 1490.96, 1753.47 and 2013.31g respectively, The age of first egg was 179.19 days, and the number of egg Produced to 300 and 500 days of age were 80.12 and 162.82 e89s, respectively. The egg weight at first egg, 300 and 500 days of a8e were 40.03 and 49.92 and 55.59g, respectively. 2 The heritability estimates based on the variance of sire, dam and combined components were 0.441-0.661, 0.120-0.490, 0.345-0.465 for body weight; 0.365, 0.207 and 0.282 for age at first egg; 0.354-0.362, 0.204-0.230 and 0.279-0.296 for number of egg production: 0.259-0.464, 0.512-0.633 and 0.386-0.540 for egg weight, respectively. 3. The genetic correlations coefficients of economic traits were as follows: the coefficients between body weight with age at first egg, number of egg Production and egg weight were 0.539-0.617, -0.520-0.157 and 0.180-0.754; between age at first egg with number of egg production and egg weight were -0.717 and 0.552-0.587; between number of egg production and egg weight was -0.383-0.381, respectively.

  • A lysozyme is isolated and purified partially form the egg white of Korean native Ogol fowl(Natural monument No. 265) by the method of direct crystallization. The bacteriolytic activities of 1% lysozyme against Staphylococus aureus 57, Bacillus subtilis ATCC 6633, and Escherichia coli NIHJ-JC2 was investigated with or without some other antibacterial materials in the nutrient broth culture. According to the results, 1% lysozyme showed the appreciable bacterolytic activities of about 12-16% to the almost of bacteria cultured. The synergistic effect with the lysozyme and some antibacterial materials on the growth inhibition of the bacteria cultured exhibited higher in order of the 0.001% magnolol -22%, the 0.001% honokiol -14% against S. aureus and of the 0.0005% erythromcin -29%, the honokiol -22%, the magnolol -l7%, the 0.005% phospholipase -6% against E. coli. And that synergistic effect against B. subtilis showed a fairly high level of about 52% with the erythromycin but not any effect with others.
