This study was carried out to investigate the distribution and morphological properties of mast cells in the ileum of Korean pheasant. In the ileum mast cells were located in the lamina propria of mucoase. The cells were mainly oval with irregular cell surface occasionally spindle-like or triangular in shape. Some mast cells had one or more tail-like long cytoplasmic processes. All mast cells had many blue granules stained by toluidine blue in the cytoplasm.

Protothalipine colorless needle crystal, mp $195-6^{\circ}$, $C_{21}H_{25}NO_{5}$) and jatrorrhizine chloride (Base A, orange needle crystal, mp $198^{\circ}$) are identified by chemical, spectral analysis, and comparison with authentic sample. Base B (reddish crystal, mp $192-4^{\circ}$) might be a artifact substance, which was changed from the jatrorrhizine chloride. Base C (yellowish needle crystal, mp $228~230^{\circ}$) and Base D (reddish needle crystal, mp $211~213^{\circ}$) were assumed to be thalifendine chloride, desoxythalidastine chloride by phytochemical and spectral analysis respectively.

In other to know the feeding preference over the degree of ripeness and size of fruits in birds, we gave them to three bird species in breeding condition, counted and analyzed the number of fruits by correspondence ordination technique. Chrysolophus pictus did not show a distinct preference in respect to degree of maturity or size of fruits of among three tree species. Columba rupestris preferred un-ripen fruits over ripen ones of Prunus yedoensis or Elaeagnus multiflora, but did not choose selectively in case of fruits of Malus sieboldii. Pavo muticus showed the reverse favorable pattern of Columba rupestris. Total feeding amounts eaten by birds were dependent on the initial feeding amounts of fruits. These results indicated that in feeding activity some birds chose differently in terms of species or maturity of fruits, but not in fruit size.

The image analyser was used for the measurement of the morphological changes of the spermatogenic cells and seminiferous tubules in the pheasant during the breeding and non breeding season. 1. The seminiferous tubules were enlarged 2.57 times during the breeding season than during the non breeding season. Only Sertoli cells and spermatogonia in the seminiferous tubules can be found during the non breeding season. 2. There is no significantly difference in the ratio of nucleus area against that of cell size in the spermatogonium between breeding and non breeding season. The ratio of area was 28.71% and 29.11%, respectively. However, the enlargement of spermatogonium was noticed during the non breeding season. 3. The highest value of the ratio of the nucleus area against that of cell size among the germ cells was measured 37.40% in the pachytene phase of the spermatocyte during the breeding season. 4. The ratio of nucleus area against that of cell size in the spermatid was 22.53%.

The alpine grassland vegetation at the west slope of Cheungseuk-bong on Mt. Paektu was investigated by Penound-Howard's cover-degree method. The floristic composition of the alpine grassland from 1,800m altitude to the top of mountain were 30 species, 2 subspecies, and 3 varieties, and most of the plants were short(height 2∼13㎝) perennial herbs and shrubs. The highest cover degree of the species in the alpine grassland zone were Ligularia jamesii, Veratrum patulum and Thalictrum aquilegifolium (1,800∼2,l00m), Vaccnium uliginosum and Rhododendron aureum (2,100∼2,l00m), and Rhododendron aureum (2,300∼2,600m). Life form of the plants were 7 species of Chamaephyte, 27 species of Hernicryptophyte, and 1 species of Geophyte. Among the presented plants, 19 species were at flowering stage. Trollius hondoemsis, Trollius japonicus, Liguiaria jamesii and Lloydia serotina were peak at flowering.

This study was conducted to obtain necessary informations for improving of wildlife rearing management. The data was gathered by surveying with questionaire. One hundred and eighty farmers which was 60 of deer and pheasant, 30 of wild boar and fox rearing farmers respectively were investigated during the summer in 1992. The results of this study are as follows : 1. Most of managers considered their rearing as a side job but agriculture was appointed as a main job from most of them except wild boar managers. 2. The major cost items were breeding stock and feeding which occupied over than half. 3. The yearly profit was the highest in deer(25.5%) but the lowest in wild boar(10.3%). 4. The break-even point was the highest in wild boar(24 mil. won) but the lowest in pheasant(7.3 mil. won). 5. The optimum sales scale for a year was deer(11 heads), Pheasant(1,027 heads), Wild boar(69 heads) and Fox (102 heads).

농사기술은 어느 한 가지 기술로 성공농사를 좌우하지 않는다. 종합예술처럼 종합기술로 이루어진다. 우리나라에는 농업전문가는 수도 없이 많다. 이 전문가들은 어느 한 분야에서 상당히 조예가 있고 정확한, 말 그대로 전문가이다. 하지만 이 분들은 논리 분야는 잘 모르는 것(?)같고 잘 모르는 것처럼 하는 것이 기본 예의이기도 하다. 즉 수직적 기능의 전문가인 반면에 수평적 기능은 약하다. 이에 비해 본인은 40년의 실전경험을 통해 전문성은 다소 떨어져도 수평적 기능에는 강하다. 그러나 농업현장에서 체득한 기술적인 경험을 전문가에 알리면 보편적으로 잘 안 받아드리는 배타적인 것이 우리의 현실이다. 그래서 의외로 수평적 기능을 가진 사람이 드물다. 어느 한 분야에서 전문가가 아닌 본인은 앞으로의 설명내용 중에 오류도 있을 테곡 논란의 여지도 있을 것이다. 하지만 '꿩 잡는 것'이 매이다. 본인은 농사실전에 막강하다. 앞으로 농사 실전에 진수, 유씨엠티농법으로 무장하고 최상의 농사를 시작하자!

Abdominal fat pad from farmed Korean ring-necked pheasants that had scanty fat depot was characterized in terms of adipocyte size as determined by free fat cells liberated by collagenase incubation. Similar parameters was also measured in the broiler chicken with similar body weight to those of pheasants. The adipocyte from pheasants was much smaller than that of broiler chicken. The results of this study suggested that the scanty development of abdominal fat pad in the pheasants appeared to be due to a smaller size of adipocyte.

The distribution of oviductal vessels of eight Korean native pheasants was observed after Latex casts of vessels. Latex was injected into thoracic aorta and posterior vena cava of these birds for cast preparation. The results were as follows: 1. The arteries suppling oviduct of the Korean native pheasants contained A. oviductalis cranialis, media, caudalis and vaginalis. The veins drainaging oviduct were stretched along the following ateries and all of the oviductal vessels were situated on the left side of the body. 2. The anterior oviductal artery arose from the pubic artery of the left external iliac artery and distributed to the infundibulum and the magnum of the oviduct. 3. The middle oviductal artery arose from the left sciatic artery and distributed to the isthmus and shell gland of the oviduct. 4. The caudal artery arose from the left internal pudendal artery of the median sacral artery and distributed to the caudal part of uterus and the cranial part of vagina. 5. The vaginal artery arose from the left internal pudendal artery of median sacral artery and distributed to the caudal part of vagina.

Though pheasants (Korean ring-necked pheasant) have been raised for several decades, their behavior and wild nature are far from domestication. The pheasant is a seasonal breeding species and lays a limited number of eggs in a breeding season. The growth rate and feed efficiency of pheasants are very low as compaired with those of chicken for meat purpose. In addition, the breeder's access to one's herd for care is not easy. From these reasons, pheasants seem to be unsuitable for meat production in a large flock at present. However, pheasant raising is expected to increase slowly in accordance with rising demand for special poultry meat. Therefore, it is necessary to improve techniques about raising, feeding and rnanagement, so that the consumer price of pheasant meat can be lowered down reasonably.
