Description
【0001】[0001]
本考案は、超音波診断装置を使用して家畜、おもに牛、馬の卵巣を映像として 写し出し、その映像を見ながら卵子を採卵する採卵器に関するものである。 The present invention relates to an egg-collecting device that projects an ovary of a domestic animal, mainly a cow, and a horse as an image using an ultrasonic diagnostic apparatus, and collects an egg while watching the image.
【0002】[0002]
現在、通常複数個の受精卵を採取する方法として雌牛にホルモン剤を投与して 過剰***を誘起し、子宮頸管を通して還流液を子宮内に送り込み、その還流液と 一緒に***される卵子を採取する方法と、屠殺場で屠殺して牛や馬等の卵巣から 未受精卵を採取し、体外培養して成熟卵にする方法とがある。 Currently, as a method of collecting multiple fertilized eggs, hormones are usually administered to cows to induce superovulation, and reflux fluid is sent into the uterus through the cervical canal to collect ovulated eggs together with the reflux fluid. There is also a method of slaughtering the unfertilized eggs from the ovaries of cattle, horses, etc. by slaughtering them at a slaughterhouse and in vitro culturing them to mature eggs.
【0003】[0003]
しかし、前者ではホルモン剤等の投与で強制的に過剰***させる為、卵巣反応 が弱まり、継続的に***誘起ができず、経済的にも効果的な採卵が行えない。 また、後者では、雌牛を特定することができない為、高品質牛の改良に役立て られない。 However, in the former case, ovarian reaction is weakened because ovulation is forcibly superovulated by the administration of hormones, etc., and ovulation cannot be induced continuously, and economically effective egg collection cannot be performed. Also, the latter cannot be used to improve high quality cows because the cows cannot be identified.
【0004】 本考案は、上記従来事情に鑑みてなされたもので、その目的とする処は、超音 波診断装置を使用して生体(正常体)から直接採卵することができる採卵器を提 供することにある。The present invention has been made in view of the above conventional circumstances, and its object is to provide an egg-collecting device that can directly collect an egg from a living body (normal body) using an ultrasonic diagnostic apparatus. To serve.
