融水小型猪的种源来自广西融水县,2012年被引到广东繁育并测定了基础数据,包括种质特性、繁殖性能、生长曲线、血液学指标、血生化指标、脏器系数、染色体分析。参照国家和地方有关实验动物标准,初步建立了融水小型猪微生物与寄生虫、环境与设施、饲料、病理学、遗传学等质量控制标准。融水小型猪能适应当地气候,繁殖良好,自然受孕率为88.3%,妊娠期平均112 d,初产平均胎产仔6.1头,经产平均产仔7.9头。融水小型猪体型小,雌雄成年体重(6月龄)分别为17.21±5.20 kg和16.35±5.23 kg,性情温顺,线粒体DNA分析表明融水小型猪比兰屿猪更为古老。通过标准化的饲养管理与质量控制,具有培育成实验用小型猪的基本条件。
Germplasm originating from Rongshui County, Guangxi was introduced to Guangdong Province in 2012 and basic data were determined including germplasm characteristics, reproductive performance, growth curves, hematological markers, blood biochemical markers, organ coefficients, chromosomes analysis. With reference to the national and local standards for experimental animals, quality control standards for microflora and parasites, environment and facilities, feed, pathology and genetics were initially established. Molluscum miniature pig adapted to the local climate and had a good reproduction. The rate of natural conception was 88.3%, the average gestational age was 112 days, the average number of first born fetus was 6.1, and the average production was 7.9. Small Mermaid piglets were smaller in body size and were 17.21 ± 5.20 kg and 16.35 ± 5.23 kg in male and female adults, respectively. Their mitochondrial DNA analysis showed that Meridian miniature pigs were older than Bilangyu pigs. Through standardization of feeding management and quality control, it has the basic conditions for cultivating experimental miniature pigs.
