Application of Biological fermentation products in Ruminant breeding

Abstract

Biological fermented products can improve the balance of rumen and intestinal flora of ruminants, promote the absorption of nutrients and enhance immunity, and the ultimate goal is to gradually replace antibiotics and achieve the role of health care and promoting growth. to provide people with healthy and safe food.

The harm caused by the abuse of antibiotics:

Due to the obvious economic benefits of the application of antibiotics in aquaculture, and the poor health of animals in high-density large-scale farming, the aquaculture industry is more dependent on the application of antibiotics. The phenomenon of over-quota and over-variety abuse of antibiotics is widespread in the early breeding industry of our country. As a result, the index of antibiotic residue in farmed products is high, which is a serious threat to food safety. The abuse of antibiotics in the aquaculture industry increases the difficulty of prevention and treatment of animal diseases, and more directly or indirectly endangers human health.

Therefore, many countries have issued laws to prohibit the use of antibiotics in animal feed. At this time, farms are in urgent need of a substitute for antibiotics that can protect animal health without posing a threat to people's health. There is no doubt that biological fermentation products are the best choice.

With the continuous research and understanding of biological fermentation products, its application in feed has been paid more and more attention by scholars at home and abroad. As a new type of active substance, biological fermentation products have been widely used in monogastric animal culture. In recent years, a large number of studies and experiments have been carried out on ruminants such as cattle and sheep, and it has been proved that biological fermentation products have significant effects. The effects of biological fermentation products on ruminants are summarized as follows: regulating animal intestinal flora; inhibiting the growth of pathogens; promoting the absorption of nutrients; improving body weight; enhancing immunity; reducing the diarrhea rate of lambs and calves.

Most of the biological fermentation products are fermented from high-quality raw materials, which are rich in a large number of beneficial bacteria. in addition, a large number of small molecules of rumen proteins, amino acids, antimicrobial peptides, lysozyme, organic acids and other nutrients are produced in the fermentation process.

The application of biological fermentation products in ruminants is mainly reflected in the following aspects:

Promote growth

High-quality nutrition is the foundation, and the utilization rate of rumen protein in cattle and sheep is 3-4 times higher than that of degraded protein, and the protein in fermented product belongs to rumen protein produced by biological natural fermentation, which is much higher than that of artificial processing, and there are no side effects. After passing through the rumen, the fermented product is directly absorbed and transformed into animal protein, which has the advantages of fast transformation speed and low energy consumption. So as to promote the rapid growth of cattle and sheep.

Protect your health

The antimicrobial peptides, bacteriocins, lysozyme and organic acids in the fermented products can effectively inhibit and kill the pathogenic bacteria and ensure the health of the intestinal tract. In addition, antimicrobial peptides can also inhibit and kill viruses, fungi and some parasites, and can enhance humoral and cellular immunity and improve body resistance. The key point is that these biological bacteriostatic substances will not produce drug resistance, and animal products will not have drug residues.

To promote digestion:

In the process of fermentation, a variety of digestive enzymes, cellulase, amylase, protease and Pectinase produced by beneficial bacteria help animals to have a positive effect on the digestion of protein, fat, cellulose and hemicellulose in diet, and effectively improve feed conversion rate. There is a direct relationship between feed conversion rate and body weight gain of cattle and sheep, so it can be seen that biological fermentation products can indirectly affect animal body weight gain by improving feed conversion rate. Experiments show that after adding biological fermentation products, the food intake of cattle and sheep increases by 30% Murray 50%. With the increase of food intake and good digestion and absorption, fermented products can really achieve the goal of promoting cattle and sheep to eat more and grow faster.

Normal ruminating:

After entering the gastrointestinal tract of ruminants, biological fermented products can regulate gastrointestinal function, showing a complex relationship with gastrointestinal flora, including symbiosis, symbiosis, competition or phagocytosis, so as to maintain and adjust the balance of rumen environment. The rumen of ruminants is a complex microecosystem, including bacteria, fungi, protozoa and a small number of bacteriophages. After a long period of adaptation and screening, ruminants and rumen microorganisms form an interdependent, mutually restricted and dynamically balanced microecosystem. As a feed additive, biological fermentation products can improve the rumen environment, which mainly includes the following points: first, stabilize rumen pH. Second, to maintain the ecological balance of rumen flora. Third, promote the growth of rumen protozoa.

A large number of experiments have proved that biological fermentation products are a new development trend in the aquaculture industry, and they are the first choice for non-resistant breeding and healthy fattening.
