Discussion of 3
Indexes such as the number of heads of diarrhea, diarrhea rate, diarrhea frequency and the like are adopted to investigate the diarrhea degree, the difference between a test group and a control group is obvious, and the result can objectively reflect the good effect of the medicine on preventing the diarrhea of the weaned piglets.
The piglet has larger stress and is easy to cause diarrhea and induce other diseases due to the drastic change of the feeding environment and the feeding conditions within 2 weeks after the piglet is weaned, so the daily gain and the feed conversion rate are reduced. In this growth stage, piglets are susceptible to diseases, and should be kept under increased management to minimize stress.
The medicine is added into the piglet feed 1 week before weaning, so that the piglet constitution can be improved, the resistance to weaning stress is enhanced, the harm of piglet diarrhea is reduced, and the piglet growth is promoted.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
