Morphological changes of the epididymal region of meat type cockerels
1984
Han, B.K. (Chonnam National Univ., Kwangju (Korea R.). Coll. of Agriculture. Dept. of Veterinary Medicine)
This study was to investigate the development pattern of epididymis in accordance with the growth of meat-type cockerels. Histological features of various ductules in epididymis of the cockerel on the age of weeks were 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

Kwak, S.D. (Kyongsang National Univ., Chinju (Korea R.). Coll. of Agriculture) | Jyong, J.S. | Kwun, H.I. | Jo, Y.J. (Kyongbuk Animal Health Experimental Inst.) | Lee, C.S. (Kyongbuk National Univ., Taegu (Korea R.). Coll. of Agriculture)
This study was undertaken to investigate congenital microphthalmia that occurred at a pig farm in Kyongbuk Korea [R.]. These microphthalmic piglets composed of 20 piglets farrowed by 3 different sows (1, 11 and 8 piglets by No. 1,2 and 3 sow, respectively) that were apparently normal during pregnancy and after parturition. Attempts were made to know epidemiological findings and histopathological changes of these piglets

1984
Lim, Y.J. (Yongin Farm Land Animal and Hospital, Yongin (Korea R.)) | Shozo, S. (Tokyo Univ. of Agriculture Tokyo (Japan))
The hemoglobin phenotype and the gene frequencies of 44 Formosan deer (Cervus nippon) in Kyunggido Korea [R.] area were examined by using cellulose acetate and starch gel electrophoresis. The method of cellulose acetate electrophoresis was simpler, more clear and preserative than starch gel electrophoresis. The hemoglobin phenotype had 3 types as (HbF) (HbFS and HbS). The frequencies of appearence were HbF 47.7% HbFS 47.7% and HbS 4.5%, respectively. The genetic factors of hemoglobin were observed as HbF and HbS and the rates of gene frequencies were 71.6% and 28.4% respectively
