As we all know, because molds are everywhere, all organic feeds will be contaminated to varying degrees, so as long as the environment allows microorganisms to multiply, it is necessary to use antifungal agents on all feeds. Although the chemical antifungal agents used in feed production have good antifungal effects, most of them have toxic side effects and phytotoxic residues. Therefore, many experts and scholars turn to the research of natural plant-based antifungal agents. Analysis shows that certain Chinese herbal medicines not only have better anti-mildew and antiseptic effects, but also can remove mycotoxins or reduce their activity. Studies have pointed out that cloves, white cardamom, and honeysuckle have obvious anti-fungal activity, and their use in feed anti-fungal can significantly delay the time of feed mildew. The alcohol extracts of Chinese herbal medicines such as tangerine peel and clove have different degrees of inhibition on the growth of fungal hyphae such as Aspergillus niger and Penicillium. The antibacterial and antifungal effects of eight kinds of Chine Phenibut Suppliers se herbal medicine extracts including Huangqin and Rhubarb. At the same concentration, pH value and temperature, the antibacterial activity of Chinese herbal medicine extracts is significantly greater than that of the chemical preservatives sodium benzoate and calcium propionate. The volatile bactericidal substances contained in some Chinese herbal medicines have slow volatilization speed and strong adsorption capacity, which can maintain a long-term bactericidal ability and have a significant anti-mold effect. In addition, studies have shown that Chinese herbal medicines such as hibiscus bark, atractylodes, and Aizhu have obvious anti-mold effects in feed. Eucommia ulmoides is a rare Chinese medicine that is a special product of our country. Eucommia ulmoides contains its own unique natural and effective bioactive components chlorogenic acid and aucubin. Eucommia chlorogenic acid has obvious antibacterial and choleretic effects, and the latter has inhibitory effects on both Gram-negative and p Buy Phenibut Online ositive bacteria. The extract of Eucommia ulmoides is used as an antifungal agent for feed, which can not only make full use of the abundant amino acids, trace elements and vitamins contained in it, but also has no pollution, no waste, and no residue. The extract of Eucommia ulmoides is a kind of brown powder, non-toxic, has a fragrant smell, is easy to use, and can be evenly dispersed on the surface of feed materials. It is a typical contact antifungal agent. Therefore, when preparing the feed, it must be fully mixed with the feed pellets and in close contact, so that it can completely kill the mold. Some scholars have compared the antifungal effects of Eucommia ulmoides extract, compound organic acid antifungal agent, and calcium propionate antifungal agent, and found that the moisture content of Eucommia ulmoides extract group feed is always Keep it to a minimum, effectively inhibiting the occurrence of feed mildew, which to some extent shows that the Eucommia extract group has a better Buy Phenibut Online anti-mold and fresh-keeping effect. At the end of the experiment, the crude fat content of Eucommia ulmoides extract group was significantly higher than that of compound organic acid antifungal agent group and calcium propionate antifungal agent group, indicating that Eucommia ulmoides extract can significantly reduce the nutritional content of feed Loss, thereby effectively inhibiting feed mildew. In the later stage of the test, due to the continuous rainy weather, the air humidity is high, and the molds multiply, but the amount of molds in the eucommia extract group is 2.9×105/g, which is significantly lower than the compound organic acid antifungal agent group and calcium propionate antifungal agent group. Mold agent group. This shows that the extract of Eucommia ulmoides has better anti-mildew and antibacterial effects. According to the results of the above experiments and our understanding of the application of antifungal agents, Eucommia ulmoides extract as a new type of “green” additive, added to feed can effectively prevent feed mildew and reduce nutrients It has a significant impact on the appearance of feed. It has the same anti-mold and fresh-keeping effect as the compound organic acid anti-mold agent. It is an ideal feed anti-mold agent.
