Unreasonable feed mix is mainly caused by insufficient crude fiber. Grass powder contains more crude fiber. The function of grass powder is not only to supplement nutrition, but also to speed up the defecation of rabbits. There is little grass powder in the feed, and the defecation of rabbits slows down, resulting in that the undigested feed remains in the intestines for a long time, causing fermentation and gas production, and diarrhea is coming!
Key points of diagnosis and control: increase the amount of grass powder or reduce the amount of feed.
However, in the reality of raising rabbits, the shortage of grass powder resources (the price is also very high) and the excessive grass powder have a great negative impact on the growth of rabbits. Especially if the rabbit is malnourished, the best feed after 3 months of age will not help. Rex rabbit is malnourished and the quality of fur is reduced. How can we safely reduce the amount of grass powder? Add additives (complex enzyme xylooligosaccharides, etc.) to aid digestion, so as to make feed digestion and absorption more thorough and reduce the presence of undigested feed in the intestines. Add effective drugs to prevent coccidial E. coli and reduce pathogenic bacteria.
Invalid drugs added to feed
The frequent addition of certain drugs and the escalation of existing pathogens lead to drug resistance. The drug that is not resistant to high temperature granulation is selected (this reason is serious). At present, especially for small farmers, the drug selectivity is too small and the variety is single. Take coccidial drugs for example. According to my investigation, 90% of Mengyin long haired rabbit farms choose dikezhuli, chlorobenzene guanidine or sulfachlorpyrazine. The risk of long-term drug resistance is too high, and there is no complete drug regimen
The solution to this problem: increase the variety of drugs, rotate the drugs, reasonably mix and reduce drug resistance (so far, there is no drug without drug resistance)
Indiscriminate use of antibiotics
There are many beneficial bacteria in rabbit intestines to help decompose the feed that is difficult to digest and absorb, and inhibit harmful bacteria. Once the drugs that kill beneficial bacteria are used, Clostridium welchii will take advantage of the situation and cause diarrhea. There are many drugs to treat diarrhea and abdominal distention, but it is more serious when used. This is the truth. Many people have used amoxicillin and florfenicol to prevent disease. According to the treatment amount, the whole group will have diarrhea within 3 days. We must pay attention to it.
Remedial measures: use large doses of microecological agents.
Poor raw materials
No matter how good the feed is, there is this mold. The tolerance of Mengyin long haired rabbits has a certain limit. Once they exceed the standard, they will get sick. General raw materials can be detected with the naked eye. Do not use those with peculiar smell and long hair. Farmers who buy grass flour must carefully check mold and sand. The addition of adsorbents such as mold removing agent and zeolite can not clean up, but also absorb the good things in the feed. Moldy corn can be used after fermentation with probiotics. This method is very effective.
