When the meat factory, adding vanilla into hamburgers or adding spice into ham is out of the fashion. The plant extract is used in diet of pigs in many countries.The pig producers and feed manufacturers have more pressures in removing part or all of therapeutic doses of antibiotics. The plant extracts application will be expanded.

With the usual way of thinking, it prevents plant extract supplies to directly claim the medicinal value. Plant extracts, usually only. Medium and true use of the benefits of foods, food and the growth of pig .But there is evidence that some of the important parts of the harmful bacteria.

The materials have been selected as ordinary herbs and spices, essential oils and greases), with quotations from (often referred to as distribution. Most of these drugs have multiple functions. Plants chunks to aid digestion, and most areas have antimicrobial properties. In all cases, the performance of herbs and spices and their active ingredients, which are directly involved in a variety of plants that contain the same active ingredient, a compound name of alcohol, many vegetables such as parsley, thyme, basil, and Yang Sun, which is a grass. these drugs vary considerably in different plants, but the concentration of the extract depends on the method of preparation.

More studies, antimicrobial activity of essential oils and fats to give a new vision. The researchers found that each plant its own characteristics similar spectrum of antimicrobial activity than antibiotics, antibiotic pharmacist and the lowest concentration of bactericidal or bacteriostatic in different organisms. Study investigated the 52 different types of vegetable oils and the antibacterial activity of the extracts, only six oils, high concentrations of the antibacterial testing a number of failures. For common conclusions, the study showed significant differences in the different parts of the plant status of a specific activity of micro-organisms. Since a total of 32 different plant extracts of E. coli culture in suspension, but the parties to a concentration of less than 0.2% of the role of different products, increased concentration of the extract, only 10 times before the antibacterial paper.

European gets a similar result in plant extracts test. The study found a significant scope of the functions of different parts of the antibacterial properties of vegetable oils. The study was carried out the lowest concentration of each essential fat inhibit the trial of a certain food pathogens, in its findings: oregano and cinnamon was significantly effective against gram negative Escherichia coli, capsicum anti-Clostridium buds bacteria effect is strongest.

Plant extract’s application scope is not recognized by many people. It may because of the unclear molecular structure for people. No pharmaceutical raw materials claim that the plants can replace the drugs, but the presence of each plant’s specific scope shows some interesting opportunities. Some special herbal extracts may be added to pig feed for against specific microbial. They will not be considered as drugs, but the ingredients to maintain the beneficial intestinal microflora and help to remove the bad pathogens. Conjunction of different plant extract products will have clear synergistic effects. Because the joint use of these products are significantly better than the single effect.Source:http://www.cospcn.com
