TL;DR: The research progresses on purulent disease, respiratory system disease and parasitosis of Musk-deer are summarized.
Abstract: In aspects of clinical semeiology,pathological inspection,etiology research,epidemiological analysis and present treatment measures,this article summarized the research progresses on purulent disease,respiratory system disease and parasitosis of Musk-deerIn order to develop the Musk-deer Farming effectively and properly with the guide of scientific theory,more research should be taken on these diseases

TL;DR: Several physiological property of ostrich semen were examined and it was found that the spermatozoa could only survive for about 24 hours when the semen was untereated or diluted 2 times with MEM and stored at 5℃.
Abstract: Several physiological property of ostrich semen were examined.Semen volume per ejaculation was 0.17~2.03 mL with spermatozoa concentration of one billion five hundred seventy million per milliliter,pH 6.7~7.3,motility 0.78~ 0.92 ,morphological abnormality rate 3.09%~13.3%. The mean survival time of spermatozoa was 72 hours when the semen was diluted 2 times with MEM and stored at 5℃.When the semen was untereated or diluted 2 time with 0.85% NaCl solution and stored at the same temprature, the spermatozoa could only survive for about 24 hours.

TL;DR: Only one species of tick parasite was found beneath scales of the animals, named as Amblyomma javanese Supino and the health conditions of infected individuals were poor.
Abstract: Fifty one living Malayan pangolins(Manis javanica) were obtained from Zhanjiang Forestry Bureau of Guangdong on August 23,2001The age structure and parasites of the animals were analyzed and examinedAccording to the wear degree of their claws,scales and hair,the behavior relationships between mother and baby,and body weight,they were divided into 4 age groups: cub,sub-adult,adult and senior,and were composted of 7(137%),21(412%),19(373%) and 4(78%) individuals respectivelySex ratio was 1∶097(♀∶♂)The epibiont and endoparasite in these pangolins were surveyed by naked eyes observation and examination of their droppingsOnly one species of tick parasite was found beneath scales of the animals,named as Amblyomma javanese SupinoThe infection rate was 6863%(35/51),but the juveniles were not infectedThe health conditions of infected individuals were poorWe also discussed the ecological security to release this species in China

TL;DR: The genetic diversity in the new varieties of Pelodiscus sinensis were studied using random amplified polymorphic DNA(RAPD) technique to compare with the usual populations of Taihu and Taiwan to show that 71.75% of the genetic variation existed within the populations.
Abstract: Pelodiscus sinensis Japanese population and Qingxiwubie are the two new varieties of soft-shell turtle.It is very importance to master the genetic relationship in Pelodiscus sinensis for further breeding and cross breeding,the genetic diversity in the new varieties of Pelodiscus sinensis were studied using random amplified polymorphic DNA(RAPD) technique to compare with the usual populations of Taihu and Taiwan.A total of 162 bands,including 110 polymorphic ones were detected from the four populations by using 23 random primers.The results showed that the level of genetic diversity was high in Japanese population,and the average genetic similarity index within each population ranked as Japanese population(0.846 9)Taiwan population(0.842 9)Qingxiwubie population(0.831 7)Taihu population(0.825 4).The maximal genetic distance occurred between Taihu and Qingxiwubie populations,while the minimum occurred between Taiwan and Qingxiwubie populations.The total genetic diversity of Pelodiscus sinensis was 0.236 8 and the intra-population genetic diversity was 0.169 9,which suggest that 71.75% of the genetic variation existed within the populations.The genetic differentiation coefficient was 0.282 7,indicating that there was a certain level of population differentiation.With the methods of UPGMA and NJ on the basis of genetic distances,the results showed that the four populations were clustered into two groups: one with Taihu and Japanese populations,and the other with Qingxiwubie and Taiwan populations.Further appropriate measurements must be taken to protect the germplasm of Pelodiscus sinensis from the reduction of genetic diversity.

TL;DR: The results showed that the red deer population size is ( 44300± 3972) deer, average population density is 0.25 deer/km 2, and total population distribution areas is about 1789600 hm 2 in this province forest Areas.
Abstract: The results showed that the red deer population size is ( 44300± 3972) deer,average population density is 0.25 deer/km 2,and total population distribution areas is about 1789600 hm 2 in this province forest Areas.Comparing with the results of red deer population survey in 1975,the red deer population dynamics reveals slighly a growth trend.From 1975 to 1990,individuals of red deer have increased 15.39%,that is the yearly rate of increase is 0.95%.But the total population distribution areas has decreased 30%~40% and appeared obviously areal distribution contraction.A new distribution pattern of red deer population has come into being in forest areas.
