Development of non-resistant culture, Chinese herbal medicine feed additives are promising

Feed additives are the "heart" and "soul" of compound feed. In the middle of the 20th century, feed additives were mainly vitamins. Later, with the industrialization of the aquaculture industry, antibiotics, chemical synthetic drugs and hormonal veterinary drug additives appeared in order to prevent and cure diseases. The application of these veterinary drug additives has contributed greatly to the healthy development of the animal husbandry and to meet the demand for animal food, but it has also brought about a series of problems. Because these drugs can accumulate in animals, which affects the quality of animal products, and thus affects human health through the food chain. Therefore, limiting the residues of veterinary drugs in animal products has received increasing attention. Analysis of the list of veterinary drug residue control proposed at home and abroad can be found that the veterinary drugs involved are mainly "Western veterinary drugs" such as antibiotics, chemical synthetic drugs and hormones, which has found a breakthrough for us to solve the problem of veterinary drug residues. The author believes that Chinese herbal medicine feed additives will have a great contribution to the development of China's anti-aquaculture industry.

First, the advantages of Chinese herbal medicine feed additives

Chinese herbal medicine is a natural resource coexisting with humans and animals, including medicinal plants, medicinal animals, medicinal minerals and their by-products. Compared with western veterinary feed additives, Chinese herbal feed additives have their advantages.

1. Advantages of Chinese herbal medicine feed additives

It has a variety of nutrients and biological activities, and has the duality of nutrients and drugs, which can prevent disease and cure diseases and improve animal performance.

It is not easy to form residues in animals, thus ensuring the quality of animal products;

Animals generally do not develop resistance to Chinese herbal medicines, and there is no vicious circle phenomenon caused by drug resistance problems, such as "the drug effect is getting lower and lower -- the drug dosage is getting larger and larger -- the residue is getting more and more serious" ;

Among the Chinese herbal medicine feed additives currently used, from the well-analyzed chemical composition and chemical structure of Chinese herbal medicines, there are no carcinogens such as benzene ring, nitro group and nitrite, which can avoid humans and animals caused by some western medicines. The three problems.

2. China's development of Chinese herbal medicine feed additives also has its unique advantages:

The application of Chinese herbal medicine in China has a long history, accumulated rich and valuable experience, and formed a unique theoretical system;

China has a vast territory, a wide variety of Chinese herbal medicines, and abundant resources, which can be obtained locally;

China has a research and teaching team of traditional Chinese medicine and Chinese veterinary medicine, and systematically studied the compatibility of Chinese herbal medicines, active ingredients, and preparation of preparations.

Second, the application in the pig industry

Traditional Chinese pigs use Chinese herbal medicines mainly for weight gain, while less attention is paid to meat quality and lean meat. The application of Chinese herbal medicine feed additives in scale-free anti-pig farms can be considered from the following aspects:

1. Promote weight gain in pigs

The main principle of the formula is spleen and digestion, commonly used drugs such as Jianqu, malt, Atractylodes, Astragalus and so on. The key spleen digestion formula can achieve two goals, one is to improve feed utilization, and the other is to increase feed intake. Consumers demand high meat quality and low fat for pork quality. Therefore, the use of Chinese herbal medicine feed additives in pigs should strictly control the feed intake of pigs. Excessive intake of feed, due to less exercise in pigs, excess nutrients will be converted into fat, leading to thickening of pork fat and affecting pork quality.

2. Promote breeding of breeding pigs

Pig farms often have excessive breeding of boars, which leads to decreased libido, decreased sperm motility, and decreased sperm count. According to the formula principle of tonifying kidney and strengthening yang, strengthening spleen and replenishing qi, it can add appropriate amount of Codonopsis pilosula, Astragalus, Ancillite, Dodder, Cistanche and Epimedium in the boar feed. For sows, people want to increase the number of births and minimize the interval between the fetuses to improve the utilization rate of the sows. Many traditional Chinese medicines have the effect of promoting animal estrus and increasing the number of ovulation in animals. The principle of medication is Bushen Yijing and Zhuangyang aphrodisiac. Commonly used drugs are Epimedium, Cuscuta, Motherwort, Rehmannia, Cinnamon and Angelica. In addition, motherwort, Wang Buliu, Mutong, Tongcao, Angelica and other medicines can be added to the sow feed to increase the sow's milk production, thereby increasing the weaning weight of the piglets; Pulsatilla, Atractylodes and Astragalus, etc., pass the drug to the piglets through breast milk to prevent diseases such as white piglets and improve the survival rate of piglets.

3. Disease prevention and treatment

Although most Chinese herbal medicines have weak antibacterial and antiviral effects in vitro, or have no antibacterial and antiviral effects, they have good preventive effects on most bacterial diseases and some viral diseases. The mechanism is to achieve antibacterial and antiviral effects by regulating the immune function inside the body, especially the non-specific immune function. The principle of medication is Buzhong Yiqi, Qingrejiedu. Commonly used drugs for Buzhong Yiqi include Astragalus, Codonopsis, Atractylodes, and licorice. Commonly used drugs for clearing away heat and detoxification include Daqingye, Banlangen, Forsythia, Zihuadi, Houttuynia, and Hedyotis diffusa. In addition, many Chinese herbal medicines have a good control effect on human and animal parasitic diseases. Commonly used drugs include Guanzhong, Betel Nut, Baizi, Gentleman, Pumpkin Seed, Bitter Skin, Artemisia annua and Agrimony.
