Abstract Large language models (LLMs) are a type of artificial intelligence (AI) that can perform various natural language processing tasks. The adoption of LLMs has become increasingly prominent in scientific writing and analyses because of the availability of free applications such as ChatGPT. This increased use of LLMs not only raises concerns about

丹顶鹤(Grus japonensis)成为濒危种在自然界中已日趋减少,而且在人工饲养条件下,丹顶鹤的繁殖普遍存在的问题是卵的受精率低,有些鹤虽然已具有适宜的饲养环境,饲料和光照等条件,但产的卵仍然不受精或受精率很低。比较可行的措施是采用人工授精技术。 70年代人工授精技术应用于鹤类繁殖在国外获得成功。1977年美国国际鹤类基金会Archibala.G.

大熊猫(Ail-uropoda melanol-euca)是我国特有的珍稀动物。由于它的繁殖力低,在饲养条件下自然交配又极少见,这就促使我们对大熊猫进行人工授精。自1978年北京动物园首次人工繁殖大熊猫成功以来,国内外其他动物园也先后用人工授精的方法繁殖了大熊猫。总的说来,人工授精的成功率不高。这涉及到精液质量、精液保存以及输精的时间和方法等诸因素。通过对精液评定选择高质量的精液做人工授精,对提高人工繁殖大熊猫的成功率具有重要意义。关于大熊猫精液的评定,张敬平(1982) Platz,Jret.al.(

对精液进行有效的冷冻保存和解冻优选是人工授精顺利开展的重要步骤。本研究在黑猩猩上做了尝试,分别用人工按摩采精、电刺激采精、附睾采精进行6次精液采集,所测精子活率为0.65~0.90,密度为1.69×1010~6.64×1011(个/L)。用自配精液冷冻液,采用CL-8800程序降温仪成功对所采集的精液进行冷冻保存。在冷冻后的10~400 d,分别对6次冻精解冻,并用人用精液优选试剂盒对其后3次进行解冻后优选。结果显示,解冻后精液活率为0.35~0.7;优选后精液活率为0.85~0.9,密度为4.5 ...
