A variety of complex, diverse, non-pathogenic microorganisms inhabit the rumen of healthy ruminants, including rumen bacteria, anaerobic fungi, archaea, and rumen protozoa. The diversity of rumen microbes has a very important impact on the health of cattle and sheep. After long-term mutual selection and adaptation, a dynamic balance of mutual restraint and interdependence has been formed between microorganisms and hosts.
This balance plays an important role in maintaining the health of ruminants, improving the production performance of ruminants, reducing environmental pollution and ensuring food safety.
However, rumen microbes are affected by the following factors:
Feed is the main factor affecting rumen microbes, of which carbohydrates are the most influential. The ratio of non-fibrous carbohydrates to neutral detergent fibers in the diet increased, and rumen fermentation changed from acetic acid fermentation to propionic acid fermentation; at the same time, the rumen microflora composition changed, and the total amount of rumen bacteria decreased.
Day age is also one of the factors that affect the host's rumen microbial composition. The rumen is not fully developed at birth. With the intake of food and exposure to environmental microorganisms, the function of the rumen is gradually developed. With the increase of age, the diversity and abundance index of rumen microbial community become higher.
Under the same conditions of diet, host health, and environmental temperature and humidity, species will also affect the composition and number of rumen microbial communities.
The internal environment has a significant impact on the rumen microecology, and changes in the external environment also affect the changes in the rumen microecological structure. Seasonal changes and changes in feeding methods are two important external factors that affect rumen micro-ecology.
Studies have shown that by feeding new-born Holstein calves with probiotics, it is found that the content of lactic acid bacteria in the calf's rumen and the ratio of lactic acid bacteria to Clostridium are significantly increased, and diarrhea is effectively suppressed. Through the determination of the full-length 16SrRNA gene sequence of adult dairy cow feces samples, it was found that although the supplement of compound probiotic preparations did not significantly change the abundance and diversity of the intestinal flora of dairy cows, the content of some beneficial bacteria and most rumen fermentation bacteria was significantly higher The control group, and some opportunistic pathogenic bacteria were significantly lower than the control group.
Factors such as age, variety, environment, etc. cannot be controlled. Therefore, the regulation of rumen microflora is mainly through adjusting diet and using microbial additives.
Microbial preparations refer to beneficial microorganisms isolated and identified from animals or nature based on the principles of microecology, or synthesized through bioengineering, and made into live bacterial preparations containing a large number of beneficial bacteria through a special process. Some also contain their metabolites or add beneficial growth-promoting factors, which are used to adjust the animal's microecological balance, enhance the animal's inhibitory effect on harmful microorganisms in the intestine, or prevent diseases by enhancing non-specific immune function, thereby promoting animal growth. A type of feed additive that improves production performance or feed conversion rate.
Improving the utilization rate of feed, reducing the cost of raising meat ruminants, and reducing the negative impact on the environment are all problems that need to be solved urgently in the breeding industry. This product is a special microecological preparation for beef cattle and sheep, which has significant effects in promoting growth and preventing diarrhea.
Increase feed intake and speed.
Improve feed utilization and reduce waste. Diarrhea decreased significantly and mortality decreased. Reduce environmental pollution.
