Liu, R.Y.,Lei, C.Z.,Liu, S.H.,Yang, G.S. Asian Australasian Association of Animal Productio 2007 Animal Bioscience Vol.20 No.2
China has numerous native domestic goat breeds, but so far there has been no extensive study on genetic diversity, population demographic history, and origin of Chinese goats. To determine the origin and genetic diversity of Chinese goats, we analyzed the complete mtDNA D-loop sequences of 183 goats from 13 breeds. The haplotype diversity value found in each breed ranged from 0.9333 to 1.0000. The nucleotide diversity value ranged from 0.006337 to 0.025194. Our results showed that there were four mtDNA lineages (A, B, C and D), in which lineage A was predominant, lineage B was moderate, and lineages C and D were at low frequencies. Lineages C and D were observed only in the Tibetan breed. The results revealed multiple maternal origins of Chinese domestic goats. There was weaker geographical structuring in the 13 Chinese goat populations, which suggested that there existed high gene flow among goat populations caused by the extensive transportation of goats in the course of history.

Mitochondrial DNA Diversity of Korean Native Goats
Odahara, S.,Chung, H.J.,Choi, S.H.,Yu, S.L.,Sasazaki, S.,Mannen, H.,Park, C.S.,Lee, J.H. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.4
Korean native goats have lived on the Korean peninsula for more than 2,000 years and are regarded as a valuable genetic resource for the world. As an initial step to investigate the genetic structures of this breed, phylogenetic analysis and calculation of genetic diversities have been performed using mitochondrial DNA (mtDNA) sequence variations. A total of 19 Korean native goats were grouped into six haplotypes and the large majority of haplotypes were present in 13 animals. All mtDNA of these Korean goats belonged to the mitochondrial (mt) lineage A and revealed remarkably small genetic distances within the population when compared with other Asian goat populations, indicating less genetic variation in the Korean native goats. These results indicate high-inbred status of the Korean native goats and will influence breeding and conservation strategies adopted for this breed.

Holstein 유우, 한우, 면양 및 한국재래산양 적혈구의 삼투적 취약성
민병만,이방환,Min, Byeong-man,Lee, Bang-whan 대한수의학회 1990 大韓獸醫學會誌 Vol.30 No.1
The study was attempted to scrutinize the normal osmotic fragility of erythrocyte in the domestic ruminants, making a comparison with that of human and canine. The animals used in the experiment were apparently healthy adult Holstein cattle, Korean native cattle, sheep (Corriedale) and Korean native goats. Osmotic fragility of erythrocytes was the highest in the Korean native goats, and the next were sheep and Korean native cattle, and Holstein cattle in order. In other words, erythrocytic resistance to osmotic lysis was the strongest in Holstein cattle and the most weak in Korean native goats among the domestic ruminants. In general, resistance of erythrocytes was stronger in human and canine than in the domestic ruminants.

Domestic goats (Capra hircus) are classifiedinto six different mitochondrial DNA (mtDNA) haplogroups(A, B, C, D, F, and G), of which haplogroup Ashows worldwide distribution. However, there is currentlyno key for genetic and geographic classification of haplogroupA. In this study, we determined the completesequences of the mtDNA control region from Koreannative goat breeds. In addition, we compared thesesequences with those of other domestic goat breeds/populationsglobally. A distinct variation site was found atposition 717. Of two types (C and T) from this variation, Ctype sequences were found only in haplogroup A, and werespecific to Eastern Asia. On the other hand, T typesequences were distributed in all haplogroups. Phylogeneticanalysis divided the two types according to differentphylogenetic locations. These results suggest that a variationin position 717 is a key for geographical classificationof mtDNA haplogroup A. Moreover, these distributionpatterns might provide for identification of the maternalorigin of goat genetic resources, including Korean nativegoat breeds.

지역통계를 활용한 가금류 및 사슴, 흑염소의 온실가스 배출량 산출에 대한 연구
이근영 ( Guen-young Lee ),연성모 ( Sung-mo Yeon ),이건모 ( Kun-mo Lee ) 한국전과정평가학회 2015 한국전과정평가학회지 Vol.16 No.1
The purpose of this study is to calculate the greenhouse gas emissions from five livestock included Poultry, Deer and Domestic goat in cities/provinces in Korea. Precedent studies concerning GHG emissions in agriculture in Korea were mostly calculated from livestock and plants in fields respectively. The GHG emissions from livestock were calculated including only enteric fermentation and livestock manure management. For implementation of national policy of GHG reduction, a policy of GHG reduction for livestock sector should be formulated on GHG emissions reflecting operating status of livestock facilities. However, GHG emissions from each type of livestock included the whole process - feed intake, enteric fermentation, farm operations, livestock manure management - are not calculated yet in Korea. In this study, we have secured national statistical resources, materials concerning operation of livestock facilities and emission factors for each type of livestock, and calculated GHG emissions from five livestock - hens, broilers, ducks, deer, domestic goats - including the whole process of operating of livestock facilities in order to construct basic data for a future policy of GHG emissions in livestock sector. We have calculated the GHG emissions from five livestock by using municipal statistics reports, national statistical resources, energy statistics, Korea Feed Association. The result shows there are some provinces of which the GHG emissions much larger than other provinces and those are increasing from 2001∼2012.
