る。[Detailed Description of the Invention] Although progress has been made in research relating to chronopotency with the progress of biotechnology in the field of science, the present situation is that it has not yet been put to practical use. In mammals, males have the right to determine sex, but it is speculated that spermatozoa in the womb are affected by the internal environment of females. This method is a method in which any farmer or Iwa livestock farmer can easily and freely select sex by improving the feeding management method at any time, anywhere, and by feeding the female body environment with the kind and amount of feed and its feeding. This is to systematically shift the sex of the offspring to the female by the method of periodical salary.

5.5％が雌であった。It is often the case that cows that normally produce only males are resold and produce females due to changes in the environment and feeding management. For breeding cattle in order to systematically obtain female calves using Japanese Black cattle based on the investigation of these changes in environmental feeding management,
Rough forage and 1Kg DCP about 25% TDN about 75% Ca about 0.8% or more P about
Concentrated feed containing 0.8% or less Mg approximately 0.25% or less and arginine approximately 1.5% or more from 10 to 14 days before estrus before daily use 1-2 kg
When artificial insemination was performed by feeding flushing 8 out of 196 heads
5.5% were female.
飼料給与の方法は発情予定日前約２週間本飼料を給与し
排卵日に授精すればよい、尚不受胎の場合を配慮して、
次の発情予定日２週間前も再度給与しておくことが大切
である。The method of feeding the feed may be to feed this feed for about 2 weeks before the estrus scheduled date and fertilize on the day of ovulation. Considering the case of unconception,
It is important to pay again 2 weeks before the next scheduled estrus.
この方法によれば農家が簡単に実行出来しかも雌子牛を
より多く計画的に生産出来て優良牛を得やすいための計
画増殖が可能である。According to this method, it is possible for farmers to carry out the planned breeding because it is easy to carry out, and more cows can be systematically produced, and superior cows are easily obtained.
