The EU has banned the use of antibiotics as feed growth promoters from January 1, 2006. However, some non-EU countries are also working to remove antibacterial agents from animal diets. The following six methods of optimizing feed can help ensure that future antibiotics are only used in sick animals.
The search for improved feeds without antibiotics can be categorized into the following six categories. Knowing your added materials is a key factor.
Antibiotics have been widely used in animal production worldwide for more than a few decades. As of 2006, the EU no longer allows antibiotics to be used for growth purposes. Outside the EU, the debate over reducing antimicrobials in feed is still ongoing. Europe's hard-won experience can provide the first insight into how feeds don't use antibiotics. These can be categorized into six methods. The first use of high-quality protein sources is a key condition, followed by inhibition and control of mycotoxins. The third and fourth important are heat treatment and acidification of the feed in order to improve the structure of the feed (5). Last but not least, add probiotics/prebiotics to improve feed and animal performance.
1. Protein digestion
The use of high quality protein sources helps to increase digestibility in the small intestine. A high-quality protein source minimizes fermented proteins in the colon and reduces the matrix of pathogens. Selectively selecting the best source of protein is the first step in reducing the use of antibiotics in feed. One thing to note is the difference in protein availability in, for example, by-products of the biofuel industry.
2. Mold and toxin
Although the mycotoxin problem has not been considered the most serious problem in most European countries, we have seen the impact of toxins on animal performance worldwide. Mold can produce these toxins, which have a negative impact on the nutritional value of the feed. Please confirm that the level of mold and toxin in the feed is below the control level, so this is also an important means to optimize animal performance.
3. Feed heat treatment
The use of heat treatment (in combination with pressure) eliminates potentially contaminating bacteria in the feed and increases the availability of nutrients. Heat treatment is a very effective way to improve feed safety and nutritional value, but there are also some factors that must be considered. For example, the cost of heat treatment. The usual practice is to use a temperature of 80-85 degrees. Each 5 degree increase can increase energy costs by 30%. Another factor to consider is secondary contamination of pathogens after heat treatment. Coolers and dust are potential risk factors for feed contamination in feed mills.
4. Acidification
The use of organic acids is one of the best ways to purify feed. There are many different products and blends available. These acids reduce the pH of the feed and stomach, resist bacteria, enhance digestion and improve technical performance. A recent study showed that heat treatment combined with organic acids can have a powerful effect on feed decontamination. This study also shows that the effects of different acidifiers can vary widely. The combination of organic acids and specific essential oil ingredients has proven to be a good choice for feed purification.
5. Structure
There are different ways to grind or cut the feed. The key is to find the best balance between digestibility and intestinal motility. Components that are easier to digest will improve FCR, but at the same time, shortening the passage time of the chyme in the intestine can cause nutritional diarrhea. The thicker the raw materials, such as the coarse cutting of the grain, the less likely the feed will be digested, but they reduce the passage time of the chyme, stimulate the peristalsis of the intestines, and enhance the fermentation in the intestines.
6. Probiotics/Probiotics
Another way to look at bacteria is not to kill harmful bacteria, but to make them good. This can be done with prebiotics/prebiotics. There are still many unclear effects, but the use of these products is on the rise. Probiotics are "good" bacteria that colonize the intestines and help maintain a healthy flora.
Prebiotics are nutrients for microorganisms. Stimulation of suitable intestinal bacteria such as lactobacilli can help maintain a good balance of the flora, which is primarily accomplished by the formation of short chain fatty acids (SCFAs) such as butyric acid. Due to the higher energy requirements of microorganisms, the disadvantages of these products are manifested in the stimulation of intestinal health, and the nutritional efficiency is also declining. This will be an eternal problem of adjusting the formula and intestinal balance according to the specific situation. New technologies such as the now marketed SCFA products such as butyric acid can act directly on the intestine without losing the effectiveness of early absorption by the stomach. Butyric acid can also be used in medicine for human colonic absorption of diseases, and its application has now entered animal nutrition.
Resisting antibiotics
In the past few years, the shortcomings of using antibiotics as growth promoters or standard management tools have become an increasingly controversial topic. The first is that people are increasingly afraid of antibiotic resistance, especially MRSA and ESBL. The resistance of antibiotics continues to increase, so human health services are also facing the fear of not being able to treat bacteria. Secondly, we saw that the effectiveness of antibiotics on farms declined due to drug resistance. Some pathogens are difficult to treat using traditional methods. The bacteria in the intestines of other animals, we call them good bacteria, are also affected by antibiotics. Worst of all, antibiotics can even cause diarrhea, not treatment.
Looking at the pros and cons of antibiotics, it is wise to look for alternatives to fight bacteria and enhance animal performance. In this way, when we need antibiotics in the future, that is, when animals face bacterial diseases, we can use antibiotics. In addition to the practices mentioned in this article, there is still a lot of work and even more to do to increase the value of the feed. These methods can reduce the use of antibiotics while increasing productivity.
Granular carbon processing in the pellet carbon basis is Huahui Company's second series of products. High hardness of pellet carbon can meet different users` demands of various effective particle size of irregular carbon and uniform coefficient.
The high adsorption carbons Granular activated carbon, which is the second main products following pellet carbon of HuaHui Company, can be produced in various distribution, the specification produced through the year includes HP-8X30 (8X30 mesh), HP-12X40,HP-5X7,HP-12X30,HP-20X40 and so on.
Granular Activated Carbon is the extension and supplement on products manufacturing and service of pellet series. This type of activated carbon is finished by machanical breaking and screening of pellet series, therefore, it has the pore characteristics of pellet activated carbon.
