Concept about health is rapidly changed into 21C. thinking logic of customer about food is changed from just food to safety food by disposition of consumption about foodsafety. But government, manufacturer, distribution trader and seller which have different recognitions about foodsafety lose trust of customer. Because they did't focus on thinking changed of customer about foodsafety. Our thinking about rapidly changed food safety being intergrated with IT technology is helping to expand and supply into market. In this article, We'll study Traceability System about cattle and pig related to food. this system was developed in livestock market. In this study, we problems from these systems after studying present construction positions of these systems and purpose of this study is investigation of actual use condition. Also purpose of this study abstracts problems which will be developed and researched.

본 시험은 논에서 가축분뇨를 활용하여 수수수단그라스 교잡종 재배시 생육특성, 수량 및 토양중의 질산태 질소의 변화를 구명하기 위하여 2003년부터 2005년까지 3년간 축산연구소(수원) 포장에서 시험을 실시하였으며 그 결과를 요약하면 다음과 같다. 수수수단그라스 교잡종의 생육특성 중 초기생육은 화학비료구 4.3에 비하여 가축분뇨를 시용한 경우 로 양호하였고 1차 예취후 재생은 화학비료구 3.0에 비하여 돈분액비, 발효돈분구는 각각 2.8로 양호한 반면

가을에 무경운 귀리 재배에 퇴비, 화학비료 및 퇴비+화학비료를 혼용한 처리로 시험결과 사초의 생산성과 품질을 비교하기 위하여 수행하였다. 본 시험은 3 처리 3 반복의 난괴법 배치로 처리는 화학비료구, 퇴비구 및 혼용구를 각각 두었다. 무경운 귀리에서 화학비료는 퇴비보다 유식물 활력은 우수하였으나, 수확시 녹체성은 화학비료구가 퇴비구보다 떨어졌다. 귀리의 건물률은 퇴비구가 다른 처리보다 높았다 (p<0.05). 귀리의 사초생산성 비교에서는 생초 수량은

Khori(高麗) refers to the Chaabog(reindeer) that live on lichens(蘚) on Mt. Soyon(鮮) in which pastures are the cold and dry plateau of North Eurasia. Thus, the origin region of the Khori or Koguryo that are the ancestors of the reindeer-herding pastoral noma

The dung beetle species living in grazing pasture in Korea and their life cycle such as characteristics of habitation and hibernation were investigated for five year. Eleven species belonging to five genera of dung beetles were found in the grazing pastur

방사성물질의 대기 누출 사고시 환경에서 핵종 거동을 모사하는 동적 섭식경로모델 DYNACON을 개선하여, 가축 (육우)의 공기 흡입과 토양 섭취가 육류 (쇠고기)의 방사능 오염에 미치는 영향을 고찰하였다. 이들 두 오염경로는 누출이 육우의 비방목 기간에 일어나는 경우에 육류의 오염에 있어서 결코 무시될 수 없는 경로라는 사실을 확인하였다. 특히 누출 후 대부분 기간에 걸쳐 토양 섭취에 의한 육류의 오염 영향이 공기 흡입에 의한 영향에 비해 우세하였다. 누출 기간동안 강우는 토양 섭취에 의한 육류의 오염에 중요한 요소로 작용하였으며, 이러한 현상은 단반감기 핵종인 보다 장반감기 핵종인 의 경우에 보다 뚜렷하였다. 이전에 수행된 우유에 대한 분석 결과와 비교하여 공기 흡입과 토양 섭취는 육류에 대해 보다 중요한 오염경로로 나타났는데, 이는 상대적으로 육류에서 핵종의 긴 생물학적 반감기 때문이다. 방목기간에 방사성물질이 대기로 누출되는 경우 누출 기간동안 강우의 유무에 관계없이 목초 섭취에 의한 오염 영향이 지배적이었으며, 결과적으로 토양 섭취와 공기 흡입에 의한 오염 영향은 우유의 경우와 마찬가지로 무시할 수 있는 수준이었다.

It is remarkable that nuclear transfer using differentiated donor cells can produce physiologically normal cloned animals, but the process is inefficient and highly prone to epigenetic errors. Aberrant patterns of gene expression in clones contribute to the cumulative losses and abnormal phenotypes observed throughout development. Any long lasting effects from cloning, as revealed in some mouse studies, need to be comprehensively evaluated in cloned livestock. These issues raise animal welfare concerns that currently limit the acceptability and applicability of the technology. It is expected that improved reprogramming of the donor genome will increase cloning efficiencies realising a wide range of new agricultural and medical opportunities. Efficient cloning potentially enables rapid dissemination of elite genotypes from nucleus herds to commercial producers. Initial commercialisation will, however, focus on producing small numbers of high value animals for natural breeding especially clones of progeny-tested sires. The continual advances in animal genomics towards the identification of genes that influence livestock production traits and human health increase the ability to genetically modify animals to enhance agricultural efficiency and produce superior quality food and biomedical products for niche markets. The potential opportunities inanimal agriculture are more challenging than those in biomedicine as they require greater biological efficiency at reduced cost to be economically viable and because of the more difficult consumer acceptance issues. Nevertheless, cloning and transgenesis are being used together to increase the genetic merit of livestock; however, the integration of this technology into farming systems remains some distance in the future.

Although economically viable, the livestock industry is currently facing a number of challenging environmental problems and highly complex social issues, many of which are related to its size and geographically concentrated nature. Increased emphasis on e

The Committee has, for the 9th consecutive year, compiled statistics of embryos collected and transferred worldwide. Geographically, all regions have participated in the survey; however, there are still some places where it has been impossible to retrieve such data (particularly in Asia). The statistics, therefore, are partially underestimated. By contrast, in other areas, the system has proven to be more efficient than before, particularly in North and South America. This has resulted in the present report, which gives a somewhat more satisfactory picture of the current situation of the ET industry. For the second year, it has also been possible to collect data for several species other than cattle. In cattle, the number of in vivo-derived embryos collected and transferred has once again increased with more than half a million embryos trans-ferred in 1999(520,712), a new record. The number of bovine in vitro-produced embryos has remained stable this year as compared with the previous year(approximately 30,000 embryos transferred). However, there are still teams that have not Yet reported their data. More than 10,000 embryos in each of the ovine and caprine species and close to 2,000 cervid embryos were reported transferred in 1999. Some 500 embryos of the equine species and a few thousand in the porcine and rabbit species have also been transferred in 1999. It is concluded that the ET industry continues to be very active, and, in many species, it encompasses a larger segment of the livestock population overall, which is to the farmer s benefit.
