The following are summary of production performances of 1,910,444 commercial broiler chickens which were reared in 24 broiler operations in British Columbia, Canada during the period of January 1983 to March 1984. 1. Average age, weight of birds shipped and feed efficiency were 47.3 days, 1.94㎏ and 2.02 for mixed broiler chickens, 41.0days, 1.73㎏ and 1.98 for cockerels and 48.1days, 1,83㎏ and 2.04 for pullets respectively. 2. There were highly significant correlations between weight (Y^, ㎏) and age of birds (X, days). Regression equations are Y^=0.0603X-0.928 for mixed birds, Y^=0.0403X-0.079 for cockerels and Y^=0.0407X-0.128 for pullets respectively. 3. There was a significant correlation between feed efficiency (Y) and age of birds (X) in mixed birds. The regression equation is Y^=0.0085X-1.641. 4. Analysis of covariance showed that market weights and feed efficiencies were significantly influenced by marketing periods. The mixed birds shipped during the period of July to September 1983 showed the least adjusted market weight while those shipped during the period of January to March 1984 showed the highest. The birds shipped during the period of January to March 1983 and 1984 showed the least adjusted feed efficiencies or the highest adjusted feed consumption per unit weight gain.

Three experiments were conducted to determine limiting amino acid of wheat-canola meal diet for broiler starter chickens. Different levels of synthetic amino acids (arginine, methionine, lysine and glutamic acid) were supplemented to diets composed of wheat, 30% of canola meal (RSM), animal fat and other minor ingredients. Chickens fed experimental diets were kept for 4 weeks and data of weight gain, feed efficiency, mortality, perosis, kidney arginase activity, and level of urea, uric acid and free amino acid in plasma were. obtained. Weight gain of chickens fed RSM diets were significantly (P $lt; .05) improved by supplementary lysine (.24%). Supplementary arginine, methionine, glutamic acid or combinations of these amino acids did not improve weight gain. Feed efficiency was significantly improved by supplementary glutamic acid. Mortality and perosis score were not significantly influenced by treatments. Data of kidney arginase activity, plasma urea and plasma free amino acid supported the weight gain data which showed that limiting amino acid is not arginine or methionine but lysine. Level of plasma uric acid was not significantly influenced by amino acid supplementation to RSM diets.

국산박류의 사료가치에 관한 연구 2 . 부로일러에 대한 박류비교시험

백인기,한인규,김춘수 ( In K . Paik,In K . Han,Chun S . Kim ) 한국축산학회 1975 한국축산학회지 Vol.17 No.4

An experiment was conducted to study the comparative feeding value of locally produced vegetable protein cakes such as soybean oil meal (44%) (S.B.O.M.), rapeseed oil meal (R.O.M.), perilla oil meal (P.O.M.), sesame oil meal (S.O.M.) and corn gluten (50%). Three hundred broiler chickens were used for 8 weeks feeding trial and successive metabolic tiral. Results obtained are as follows; 1. Weight gains were significantly (P$lt;0.01) different among treatments showing the best gain in S.B.O.M. group and then P.O.M., R.O.M., corn gluten and S.O.M. group in that order. Feed intake showed same trend as weight gain did. For the feed efficiency, S.B.O.M. group was significantly (P$lt;0.01) superior to the other groups and S.O.M. group was significantly inferior to the other groups. Among the groups of receiving R.O.M., P.O.M. and corn gluten, differences were not significant each other in feed efficiency. 2. Amino acids compositions of R.O.M. and S.B.O.M. were better than that of other protein feeds considering their relatively high E.A.A. Index of 76.32 and 76.21 respectively. P.O.M., S.O.M. and corn gluten were low in lysine content while methionine contents were relatively high. 3. Nitrogen corrected M.E. values of S.B.O.M., R.O.M., P.O.M., S.O.M. and corn gluten were 2,367㎉, 843㎉, 2.234㎉, 1,305㎉ and 4,283㎉, respectively. Rates of nitrogen retention of P.O.M., S.B.O.M., R.O.M., corn gluten and S.O.M. were 59.38%, 51.18%, 54.11%, 44.80%, and 36.01%, respectively. 4. Dry matter and crude protein availabilities of finisher diet of R.O.M. group and S.B.O.M. group were higher than that of other groups but not significantly different. On the contrary however, crude fat availabilities of R.O.M., and S.B.O.M. group were significantly (P$lt;0.01) lower than that of other groups. 5. Thyroid gland weights and total serum cholesterol contents were significantly (P$lt;0.05) different among treatments. However, the relationship between thyroid gland weight and cholesterol content was observed only in R.O.M. group. Corn gluten was verb effective to increase skin pigmentation. 6. Production cost for 1㎏ of broiler meat of S.B.O.M. group was lower by about 20 won to 30won than that of R.O.M., corn gluten, or P.O.M. group, and by about 100won than that of sesame oil meal group which was least for the performance among the treatments.

동해 표기 관련 일본 주장 비판 연구: IHO S-23 분석을 중심으로

백인기 동북아역사재단 2019 영토해양연구 Vol.18 No.-

At the 6th United Nations Conference on the Standardization of Geographical Names(1992), both South and North Korea raised the issue of the name on the East Sea. Since then, Japan has insisted on the exclusive use of the name “Sea of Japan”. This study attempts to criticize the problem of Japanese claims by analyzing the names of the oceans and seas used in IHO S-23. The IHO seeks standardization in the technical fields related to navigation. IHO arranged official maritime names for the convenience of navigators and other users. In IHO S-23, multiple names have been allowed to be used in various types for bodies of water and maritime features that contain area beyond the territorial sovereignty of a single nation. According to this tradition, experts from IHO member countries discussing the issue of the East Sea and the Sea of Japan at IHO tended to take a favorable position of mutlple naming. As an important member of the IHO, Japan is required to look back on the purpose and spirit of the IHO S-23, and to actively review the multiple naming of the “East Sea/ Sea of Japan“. 1992년 유엔 지명표준화회의에서 남북한이 동해 표기 문제를 제기한 이후 지금까지 일본은 일본해 단독표기를 고집하면서, 정부의 홈페이지를 통해 일본해 단독표기를 주장하고 있다. 본 연구는 IHO S-23(해양과 바다의 경계)에서 사용하는 바다 명칭의 분석을통해 일본 주장의 문제점을 비판하였다. IHO는 항해와 관련된 기술적 분야의 표준화를 추구한다. 해양지명에 있어서도 사용자들의 편의를 위해 공식 해양지명을 만들어 이용해왔다IH. O 는 여러 국가와 관련된 해양의 명칭에 대해서 다양한 형태로 복수의 지명을 병기해왔다. 이러한 전통에 따라I HO에서 동해와 일본해 병기 문제를논의하는 회원국 전문가들도 동해병기에 우호적이다. 일본은 IHO의 오랜 회원국으로서 IHO S-23의 도입 목적과 정신을 되돌아보고, 동해/일본해 병기의 타당성을 깊이 성찰할 필요가 있다.

Canola박과 종자의 급여가 산란계의 혈장과 계란의 thiocyanate 이온함량에 미치는 영향

백인기,Robblee, A R 한국축산학회 1984 한국축산학회지 Vol.26 No.6

An experiment was conducted to determine the influence of feeding canola meal (CM) and canola seed (CS) to laying birds on the level of thiocyanate ion in blood plasma and egg. Blood and egg samples were obtained from Single Comb White Leghorn hens, 50 weeks of age, which had been placed on 16 different CM and CS diets. Concentration of thiocyanate ion in samples was determined with a gas chromatography equipped with an electron capture detector. The levels of thiocyanate ion in blood plasma of birds fed 10 to 20% of CM or 10 to 15% of CS were 4 to 5 times higher than those of soybean meal (SBM) controls. The levels of thiocyanate ion in egg serum of birds fed 10 to 20% of CM or 5 to 15% of CS were 1.5 to 2.5 times higher than those of SBM controls. The level of thiocyanate ion in blood plasma and those in egg serum were highly correlated (r = .87, P $lt; .01). The influence of CS on the level of thiocyanate was much greater than CM if comparison is made on oil-free basis. The level of energy or source of energy may influence the level of thiocyanate ion in egg serum of birds fed CS diets.

Fructooligosaccharides 의 급여가 육계의 장내 Salmonella typhimurium 증식 억제에 미치는 효과

백인기,남궁환,최규형 한국축산학회 1994 한국축산학회지 Vol.36 No.3

A feeding trial was conducted to investigated the effects of 44% fructooligosaccharides(FOS) argainst colonization of Salmonella typhimurium in broiler chickens, In a 2∼4 factorial arrangement (two challenge levels of Samonellart at 10³ and 10^6·four FOS levels at 0, 0.5, 1, and 2%), 14 chicks were randomly assigned to each treatment. On the 3rd day posthatch, chicks were challenged with Salmonella typhimurium by crop gavage and stressed by deprivation of feed and water on day 11 for 24 h. Weight gain and feed intake were measured on the 10th and 18the day posthatch, when seven chicks per treatment were saerifieed each time. Intestinal contents and sections of intestine were collected and processed for analysis. There were no significant differences in weight gain and feed/gain ratio between 10³ and 10^6 treatment groups. The FOS supplemented groups showed a numerical improvement over the control in weight gain by 16∼28% on the 10th day and by 24∼31% on the 18th day posthatch. The effects of FOS supplementation on the performance tended to be greater in the Salmonella 10³ treatment groups than in 10^6 treatment groups on day 10. The colony forming units (efu) of Salmonella typhimurium in the cecal contents were very low in the FOS supplemented groups compared to the control and the percentages of the cecal cultures that tested positive for Salmonella typhimurium were 29∼71 for FOS supplemented groups compared to 100 for the control. On day 18, the colony forming units of Salmonella typhimurium in the cecal contents and cecal cultures that were positive for Salmonella typhimurium were numerically lower in the 19³ treatment groups than the 10^6 treatment groups, and lower in the FOS supplemented groups than in the control, bu there were no differences among the FOS supplemented treatments. The pH of the ceal contents was lower in the FOS supplemented groups than in the control. The length of ileal microvilli in the FOS supplement groups was about two times longer than that of the control group. It was notable that the provision of FOS to the broiler diets alleviated the Salmonella-induced necrosis in the cecal mucosal epithelium. In conclusion, the supplementation of FOS at the level of 0.5% in the broiler diet could suppress the cecal Salmonella colonization and alleviated the reduction of broiler performance induced by Salmonella invasion.
