수평아리 사체를 이용한 효모의 최적 배양 조건과 효모배양물이 육계의 성장에 미치는 영향을 조사하였다. 수평아리 추출물의 단백질 농도는 72시간 동안 추출되었을 때 가장 높았으며, 수평아리 사체에서 추출물을 얻기 위한 물의 첨가 비율은 수평아리 사체의 무게에 1.5배(v/w ratio)가 적당하였다. 수평아리 사체의 추출물에서 지방은 효모의 성장에 영향을 미치지 못하였다. 수평아리 사체의 추출물과 4% sugarcane molasses로 구성된 SCELP2 배지는 1% yeast extract, 2% bacto pepton 그리고 2% glucose로 구성된 YEPD 배지보다 효모수가 26% 더 증가하였다. 또한 SCELP2 배지에 4% 폐이스트를 첨가한 SBYW2 배지는 SCELP2 배지보다 효모수가 8% 증가하였다. SBYW2 배지에서 배양된 효모배양물을 5주 동안 육계에 급여한 결과 종체량은 4% 첨가구가 대조구보다 9% 증가하였다. 따라서 본 연구 결과 부화부산물로 발생되는 수평아리 사체는 사료용 효모배양물을 생산하기 위한 효모배양 배지의 질소원으로서 이용될 수 있음을 의미한다.

The poultry farmers of rural area in Bangladesh usually prefer raising cockerel to broiler due to availability, low price of chicks, requirement of less space and feed, and high price of meat and the farmers believe that the cockerels are less susceptible to diseases in comparison to broilers. This study was carried out to observe the pathology of diseased cockerel in 3 farms of rural area in Bangladesh. A total of 974 birds were examined and the diagnoses of different disease/conditions were based on the history, clinical signs, characteristic gross, tissue alterations, clinical pathology and isolation and identification of the pathogenic organisms. The diseases in this study included infectious bursal disease, yolk sac infection, vitamin E deficiency, coccidiosis, and other diseases. The proportionate mortality rate were $7.29\%,\;0.62\%,\;0.72\%,\;0.21\%\;and\;0.10\%$, respectively, which indicated that most of the fatal causes of death were due to infectious bursal disease. Age group of 2-8 week old were the most susceptible to this disease and E coli was suggested as a cause of yolk sac infection. The data also suggested that the coccidiosis in rural areas of Bangladesh has decreased due to awareness of the farmers and routine use of coccidiostates.

The purpose of this research was to re-illuminated the artistic value of costumes that had shared identical history with human beings through the formation and the progress of the newly introduced Russian avant-garde an. This resulted from the fact that the Russian avant-garde art changed the human esthetic sense through the style of art that Larionov and Goncharova introduced in the 20th century. The research method defined the formation and the progress of the development of the Rayonism centering the works of art by Larionov and Goncharova. Based on this method, larionov and Goncharova designed the set and the costumes for the Ballets Russes of Serge Diaghilev and studied the molding characteristics of the costumes worn in the performing an. The result were as follows. First of all, Larionov's costumes of art were all manufactured based on the theme of nature and genesis. In other words, Larionov represented the sun as a humanistic god through the white night, the natural weather condition of northern Russia. His costumes also displayed the symbolic meaning of the personification of animals like birds and cats, which emphasized the importance of both nature and tradition. However, he used Rayonism expression when he designed costumes by applying the nature themes. On the other hand, Goncharova applied the Spanish passion, the Russian folk art lubok, and goldern cockerel or religious icon-paintings in her costumes. she pursued straight lines and abstract shapes in her costume design. her design displayed the Rayonism influence through the separation between the lines and the surfaces, whic defined the costumes as a decorative art experiment. Therefore, the study of Larionov and Goncharova had one realize that Rayonism was not only an art form of Avant-garde, but it also became the basis of the molding character of all the artworks. Larionov and Goncharova reflected the miracle of the transformation of the 20th century in their costume designs.

Seven rc mutant and seven normal male birds (Rhode Island Red suie, RIR) were used in this study to determine the effects of rc mutation on semen characteristics, testosterone profile and spermatogenic tissues. All birds were randomly selected at week 12 of age and housed in individual cages and were fed and watered ad libitum. The birds were exposed to a 14L:10D light cycle during experiment. Semen were collected at weeks 22 to 23 from each bird twice a week and evaluated for semen volume (SV), sperm concentration (SC), total sperm count (TSC), percent of sperm motility (%SM), dead sperm (%DS), and sperm metabolic activity (SMA). To determine the testosterone concentration (TC) in plasma, blood was collected at weeks 12, 16 and 18. Testicular tissue were collected, processed and evaluated for semineferous tubule diameter (STD), round spermatid number (RSN), percent elongated sperm (%ES) and semineferous tubules length (STL). Body weight (BW), comb weight (CW) and testes weight (TW) were weighted at the end of experiment (week 23). The SV, TSC and %SM were significantly higher in normal birds but the %DS was higher in blind birds (p<0.05). The SC did not differ significantly between the two groups but its value was higher in normal birds. The sperm metabolic activity in the first h of collection did not differ significantly between the two groups but after 24 h, the level of SMA in normal group was significantly higher (p<0.05). The level of TC did not differ significantly between the two genotype groups but normal birds had higher TC in all collections except the last one. The STD, RSN, %ES and STL in normal birds were higher when compared to blind birds but the differences were insignificant except for ES percent. The BW, CW and TW between the two groups did not differ significantly but the weights were higher in normal group compared to blind birds. Statistical analysis of semen characteristics, testosterone profile and histological factors were indicated detrimental effects of rc mutation in prepubertal RIR blind male birds due to lack of light.

The work was conducted with tole purpose of investigation on the development pattern of epididymis in accordance with the growth of meat-type cockerels. 1. Histological features of various ductules in epididymis of the cockerel on the age of weeks were as follow: within 10 weeks after hatching rete testis and connecting ductules were well developed but efferent ductules were observed in immature form. During 10th to 20th week, the lining epithelium of various ductules in epididymis was in the developing stage near to the mature form. From 21th week, various ductules were abruptly matured. Lumen of rete testis was lined by simple squamous or simple columnar epithelial cells and that of efferent ductules, having many folds and being larger than any others, were lined by ciliated pseudostratified columnar epithelium with ciliated columnar cells, clear cells and basal cells were noted. Luminal epithelium of connecting ductules was composed of ciliated low pseudostratified columnar epithelial cells, ciliated columnar cells, clear cells and basal cells. The luminal surface of epididymal ducts was pseudostratified columnar epithelium and which was composed of high columnar cells and basal cells. 2. In the India ink absorption test, India ink granules were noted above the nucleus of some cells in the efferent ductules and the connecting ductules at 7 hours after administration of India ink to the mature epididymis, but not absorbed in the other ductules. The granules reactive to acid phosphatase were most abundant in some epithelial cells of efferent ductules and connecting ductules, especially above the nucleus of cells. The granules reactive to alkaline phosphatase were noted on the luminal border of efferent ductules. The granules reactive to PAS were scattered in the epithelial cells of efferent ductules and connecting ductules.

The purpose of this research was to re-illuminated the artistic value of costume designs that had shared identical history with human beings through the formation and the progress of the newly introduced Russian avant-garde art. This resulted from the fact that the Russian avant-garde art changed the human esthetic sense through the trend of art that Natalia Goncharova introduced in the early 20th century. The research method defined the formation and progress of the development of the Neo-Primitivism centering the works of art by Natalia Goncharova. Based on this method, Goncharova designed the set and the costume designs for the Ballets Russes of Serge Diaghilev and studied the molding characteristics of the costumes worn in the performing art.
