Lactobacillus plantarum: the lactobacillus plantarum is one of lactobacillus, the optimal growth temperature is 30-35, the lactobacillus plantarum is anaerobic or facultative anaerobic, the strain is a straight or bent rod, the strain is single or sometimes paired or chained, the optimal pH value is about 6.5, and the lactobacillus plantarum belongs to homofermentation lactobacillus. The bacterium is different from other lactic acid bacteria in that the number of viable bacteria of the bacterium is higher, a large amount of acid can be produced, the PH value in water is stable and not increased, and the produced acidic substances can degrade heavy metals; since this bacterium is an anaerobic bacterium (facultative aerobe), it produces a characteristic lactobacillin, a biological preservative, during the propagation process. In the middle and later period of cultivation, as the excrement and the residual feed of animals are increased, the animals sink to the bottom of the pond and are rotten, a lot of germs are bred, a large amount of ammonia nitrogen and nitrite are generated, and the phenomenon that the bottom is killed by theft is serious. If the lactobacillus plantarum is used for a long time, the rot of bottom excrement and residual feed can be well inhibited, the increase of ammonia nitrogen and nitrite is reduced, the consumption of chemical degradation elements is greatly reduced, and the breeding cost is reduced.
Pediococcus pentosaceus: pediococcus pentosaceus, round colonies, opalescent, smooth, convex, neat-edged, opaque, gram-positive, cocci. Pediococcus pentosaceus (p. pentosaceus), spherical in cell shape, with a diameter of 0.8-1.0 μm. The optimal growth temperature is 35 ℃, and the maximum growth temperature is 42-45 ℃. Sensitive to hop preservatives. It is distributed in wort and fermented plant material, such as pickled vegetables, sauerkraut, silage, etc.
Bifidobacterium lactis: is one of the dominant bacteria in the intestinal tract of humans and many mammals. Belongs to the flora in microecology. The bacterium was first isolated from the faeces of breast-fed infants in 1899 by Tiser, the institute of Pasteur, France, and indicated that it has important effects on nutrition and prevention of intestinal diseases in infants. This bacterium is an important physiological bacterium in the human and animal intestinal tracts. Participate in a series of physiological processes such as immunity, nutrition, digestion, protection and the like, and play an important role.
Lactobacillus acidophilus: lactobacillus acidophilus belongs to the genus Lactobacillus, gram-positive bacilli, with rounded rod ends, which are mainly found in the small intestine and release lactic acid, acetic acid and some antibiotics acting on harmful bacteria.
Lactobacillus delbrueckii: lactobacillus delbrueckii is a gram positive bacterium isolated by Beijerinck in 1901 and named under the name of m.delbruck, german bacteriologist. Lactobacillus delbrueckii has relatively high requirements on a culture medium during culture, and can utilize various sugars such as lactose, glucose, fructose and mannose as single carbon sources. Lactobacillus delbrueckii has found widespread use in the fermentation industry, such as dairy fermentation, meat product fermentation and beer fermentation, and lactobacillus delbrueckii subsp bulgaricus is one of the most commonly used species in dairy fermentation, and is one of the most economically valuable lactic acid bacteria. The acid production capacity and the strain number of the lactobacillus delbrueckii subspecies bulgaricus and the streptococcus thermophilus are higher when the lactobacillus delbrueckii subspecies bulgaricus and the streptococcus thermophilus are cultured together in milk than when the lactobacillus delbrueckii subspecies bulgaricus and the streptococcus thermophilus are cultured in the milk alone, and the synergistic effect exists between the two bacteria. The respective metabolic mechanisms of these two bacteria can utilize substances released from each other to meet the needs of their own metabolism. The streptococcus thermophilus can provide formate and carbon dioxide to stimulate the growth of lactobacillus bulgaricus, and the lactobacillus bulgaricus can synthesize extracellular protease to degrade proteins in raw materials so as to provide amino acids and small peptide substances required by growth of the streptococcus thermophilus lacking the protease
Carotenoids: carotenoids (carotenoids) are a generic name for an important class of natural pigments, which are commonly found in yellow, orange-red or red pigments of animals, higher plants, fungi, algae. It is an isoprenoid polymer containing 40 carbons, i.e., a tetraterpene compound. Typical carotenoids are formed by 8 isoprene units joined end to end. The color of carotenoids varies depending on the number of conjugated double bonds. The greater the number of conjugated double bonds, the more red the color shifts.

The test method comprises the following steps: cleaning and disinfecting the pen house before the test, recording the ear size of the test pig, pre-feeding the test pig for 7 days after the test pig enters the test pig, gradually adding the feed prepared in the corresponding example or the comparative example from the original feed in the first four days, and completely feeding the corresponding feed in the last 3 days. And (3) weighing 1 pig in the current morning on an empty stomach in the formal period, wherein the formal period is 60 days, and after the test is finished, weighing 33 pigs in the next morning on an empty stomach, and slaughtering, sampling and measuring.
The test results are shown in tables 1-2 below
TABLE 1
As can be seen from Table 1, the average back fat thickness of the pigs is obviously affected in examples 1-7, the feed provided by the invention has the fat reducing effect, the fat content of the muscles in examples 1-7 is obviously reduced compared with that in comparative example 4, and the moisture difference is not large, which indicates that the feed provided by the invention can maintain the nutritional ingredients of the pork in the process of reducing the fat, and as can be seen from the comparison of comparative examples 1-3 and example 1, when the lactic acid bacteria starter is Lactobacillus plantarum and Pediococcus pentosaceus, the fat reducing effect in the fat reducing process is obviously better than that of the lactic acid bacteria starter which is only Lactobacillus plantarum, the radix isatidis-herba houttuyniae is an important component added to the feed, and the mulberry leaves and the kelp are indispensable parts in the fermented feed.
TABLE 2
As can be seen from table 2, the feed of examples 1 to 7 can significantly increase linoleic acid, linolenic acid, arachidonic acid, and unsaturated fatty acid among fatty acids, and linoleic acid and linolenic acid are all essential amino acids required by human body, and have important effects on maintaining lipid metabolism balance of human body, reducing blood cholesterol, preventing atherosclerosis, improving immunity of human body, and the like, and arachidonic acid is an important substance for development of human brain and optic nerve, and has important effects on preventing cardiovascular diseases, diabetes, tumors, and the like. The results show that the feed of the examples can increase the proportion of the total amount of various functional fatty acids and unsaturated fatty acids, thereby obviously improving the pork quality.
Finally, it should be noted that: the above examples are only for illustrating the technical solutions of the present invention, and are not limited thereto.
