乳制品科学乳制品科学
羊的养殖羊的养殖

背景情况:

乳酪质量对于新生儿的生存和牲畜的生长至关重要.
当地的山羊品种可能具有独特的遗传特征,影响乳母素的组成.
农业系统 (密集型和半扩展型) 可以影响牛奶的生产和质量.

研究的目的:

描述和比较意大利本地山羊品种 (Frisa Valtellinese,Orobica,Lariana) 和一个国际性品种 (Camosciata delle Alpi) 的乳头质量.
调查品种和养殖系统对胆乳主要成分的影响.
为了确定特定的乳母参数,区分本地和世界性的山羊品种.

主要方法:

从每个品种的30只山羊 (Frisa,Orobica,Lariana,Camosciata delle Alpi) 采集了乳头样本.
分析包括脂肪,乳糖,蛋白质,总固体,免疫球蛋白G (IgG) 和乳糖的量化.
使用单变量和多变量统计分析来评估品种和系统效应.

主要成果:

拉里亚纳品种的脂肪和总固体含量最高,而奥罗比卡品种的乳糖含量最高.

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...
