As a feed additive, Chinese herbal medicine has the dual functions of medicine and nutrition, which can prevent disease, improve production performance and improve the quality of animal products. According to the theoretical analysis of modern pharmacology and nutrition, Chinese herbal medicine contains anti-bacterial components, alkaloids, polysaccharides, terpenoids, volatile oils, tannins, organic acids and other biologically active substances, and also contains a certain amount of amino acids and minerals. , vitamins, unknown growth regulators and pigments. Production practice shows that Chinese herbal medicine feed additives have the advantages of low cost and no residual phytotoxicity.
First, enhance the color of
The use of unique natural pigments contained in Chinese herbal medicines increases the color of animal products. Calendula petal powder contains more yellow lutein (mainly lutein), including Violaxanthine, edulis, and jade red. 0.15% of the laying hen feed, yellow lutein can significantly increase the brightness of egg yolk. Marigold (Golden Chrysanthemum): Flower contains blue fluorescent substance alpha-trithieny 15-21 mg/kg, flowers, anthraquinone pigment Helenien 0.74%, flavoxanthin Wait. Adding 0.3% to the feed, the chicken's egg yolk, skin and fat are excellent in color enhancement.
Use carotenoids rich in Chinese herbal medicine to increase the color of animal products. Carotenoids are natural yellow or orange and are an effective natural colorant. In cattle, carotenoids are deposited in adipose tissue, and the carcass is yellow, affecting the quality of the beef. In poultry, carotenoids are deposited in claws, cockroaches and subcutaneous fat to color them, improving the quality of poultry carcasses. The carotenoids in the laying poultry are deposited in the yolk to make it yellow, which improves the quality of the eggs. Carotenoids mainly affect the appearance color of livestock products through their wavelength and concentration. Different kinds of carotenoids have different coloring ability in different kinds of animals. The main coloring effect in ruminants is carotene pigment, while in poultry, it is mainly oxygenated carotenoids.
Second, flavor
Improve the flavor of animal products with Chinese herbal medicines rich in aromatic volatile oils. Cinnamon: Cinnamon skin contains 1%~2% of volatile oil (cinnamon oil). The main component is Cinnamaldehyde (75%~90%), and contains a small amount of cinnamic acid and phenylpropyl acrylate. Cinnamon is added to the cow's feed, and the extruded milk has a characteristic aroma of cinnamon. Perilla: Whole grass contains about 0.5% volatile oil, containing about 55% of Perillaldehyde, 20% to 30% of L-limonene and a small amount of α-pinene. The volatile oil of the leaves contains Isoegomaketone, etc., and the volatile oil of Perilla frutescens contains Isoamyl 3-furylke-tone, perillaldehyde, α- and蒎-pinene, d-limonene, l-linalool, terpene, menthol, menthone, perilla alcohol (Perilla alcohl), dihydroperpelol, eugenol. A certain proportion of perilla is added to the cow's feed, and the extruded milk has a special sweet taste.
Nie Guoxing (2000) reported that feeding broilers with garlic, pepper, nutmeg, cloves and ginger can improve the quality of the chicken and make the chicken flavor richer. Cheng Zhonggang et al (2002) added 100-250 mg/kg of soy in the diet of finishing pigs. The results showed that different doses of soy were able to increase the lean meat rate and fat-free lean meat weight gain (P>0.05) to 250 mg. The effect of the /kg group was the most significant; the drip loss of the muscle in the experimental group was significantly reduced, and the addition of 100 mg/kg and 250 mg/kg reduced the drip loss by 29% and 36.9%, respectively (P<0.05); the addition of soy was also significantly reduced. The test pigs had thick backs (P<0.05).
Third, increase nutrients
The use of special ingredients contained in Chinese herbal medicines to increase nutrients that are not normally found in animal products, and to produce animal products with specific uses. Suzi (Perilla fruit): 45.30% and VB1 containing fatty oil. The finishing pigs began to add 3% of succulent powder to their feeds from the first month before slaughter, and they were fed to the slaughter. As a result, the α-linolenic acid in the pork increased by 0.7% to 1.0% compared with the control group. It has "health pork" for preventing and treating diseases such as high blood pressure, heart disease and diabetes. Adding proper amount of Suzi and VE to the broiler feed can make the chicken contain more α-linolenic acid, which is a “healthy chicken†with diseases such as prevention of arteriosclerosis and high cholesterol. Shao Shuli et al. (2002) added the tender leaves of seabuckthorn to the chicken diet. It was found that the tender leaves of seabuckthorn can increase the content of amino acids and protein in chicken meat, improve the quality of chicken meat, and enhance the immunity of animal organisms.
Fourth, improve nutritional quality
Use Chinese herbal medicine to reduce cholesterol in egg yolk and produce health-care eggs that are good for consumers. 16% safflower seeds were added to the laying hens. The content of polyunsaturated fatty acids (PUFA), especially essential fatty acids (EFA, including LA, ALA, AA) in the egg yolk was significantly increased, and the cholesterol content decreased by 29.37%. Reduce cholesterol intake, supplement EFA, reduce cholesterol synthesis in the body, and prevent cardiovascular disease.
Japanese scientists have found that adding perilla fruit to pig and laying hen feed can improve pork quality and increase the content of α-linolenic acid in pork by 1.9% to 3.7%, which helps pork eaters to prevent and treat diseases such as hypertension. At the same time, it can increase the content of α-linolenic acid in eggs, and has already been marketed.
Chinese herbal medicines are taken from nature and maintain the natural form and biological activity of various substances contained in them. They are used in livestock and poultry farming and have the dual functions of nutrition and medicine. The use of Chinese herbal medicine to produce characteristic animal products and improve the quality of animal products not only broadens the application of Chinese herbal medicines, but also has a positive and far-reaching impact on enriching the diversity of animal products and enhancing market competitiveness. Due to the complexity of the substances contained in Chinese herbal medicines and the different tastes, it is necessary to conduct in-depth research on molecular biotechnology in the mechanism of Chinese herbal medicines to improve the quality of animal products. In the actual production, we should adhere to the principles of science, economy and utility, take into account the different physiological stages of different livestock and poultry or the same livestock and poultry, combine with health promotion and growth, strengthen the purpose function through the group, enhance the use effect, and improve the economy. benefit. It is believed that the breakthrough in the theory and technology of Chinese herbal medicine in improving the quality of animal products will greatly improve the quality of livestock products produced by large-scale intensive farming.
