Description
Technical Field
The invention relates to the technical field of fermented feed, in particular to microbial fermented pig feed and a preparation process thereof.
Background
The feed prepared by fermenting the coarse feed by microorganisms is called as fermented feed, and the fermented coarse feed comprises bran, rice bran, straws, pasture, various cakes (dregs), pomace, vinasse and the like. The common breeding feed only can ensure that the pigs grow quickly, but cannot provide various nutrients required by the growth of the pigs, and the common pig feed has the problems of nutrient component deficiency, toxin and a large amount of antibiotics and the like. Therefore, pigs fed with the common feed have poor health condition, and the pork quality and the edible safety are poor. Although the fermented feed can meet the nutritional requirements of pigs, the raw materials are different in fiber and fermentation degree. Even some raw materials are rich in nutrition, but are softened to be beneficial to fermentation, otherwise early-stage zymophyte can not grow. Different raw materials cannot adopt the same fermentation treatment method.
Disclosure of Invention
The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, the invention aims to provide a microbial fermented pig feed, which is used for fermenting feeds with high fiber content and difficult absorption, is easy to absorb the fermented feeds, has low raw material cost and high nutritional value, is easy to absorb after fermentation, and is subjected to different treatments according to the properties of the raw materials, so that the raw materials are better homogenized.
The microbial fermentation pig feed provided by the invention comprises the following raw materials in parts by weight: 20-30 parts of barley flour, 15-20 parts of bran powder, 20-25 parts of corn cob powder, 10-15 parts of beans, 8-10 parts of fish meal, 15-20 parts of potato powder, 15-20 parts of vegetables and fruits, 2-4 parts of sodium bicarbonate and 10-15 parts of bacteria liquid.
In some embodiments of the invention, the composition comprises the following raw materials in parts by weight: 25 parts of barley flour, 18 parts of bran powder, 22 parts of corn cob powder, 13 parts of bean dregs, 9 parts of fish meal, 18 parts of potato powder, 17 parts of vegetables and fruits, 3 parts of sodium bicarbonate and 12 parts of bacteria liquid.
Corn is usually thrown away directly after corn kernels are removed, a large amount of raw materials are wasted, the corn contains rich fiber and corn starch, the corn is made into powder, the eating of pigs is facilitated, and the material utilization rate is also improved.
In other embodiments of the present invention, the beans are a mixture of soybean hulls and soybean meal, and the mass ratio of the soybean hulls to the soybean meal is 3: 5.
In other embodiments of the invention, the fish meal is a powder made from dried small fish, which has a weight not exceeding 30g when fresh weight. The small fish is used because of low cost, high nutritive value and easy processing into powder.
In other embodiments of the invention, the vegetables and fruits comprise rotten vegetable leaves, damaged fruits, fruit peels and carrots discarded in the vegetable market, the rotten vegetable leaves are cleaned, thrown away and cut into slices, the fruits and the fruit peels are cleaned and cut into blocks or slices, the carrots are cleaned and cut into blocks, and then the raw materials are mixed and put into a juicer to be squeezed into the vegetable and fruit juice.
In other embodiments of the invention, the bacterial liquid is a mixture of lactic acid bacteria, yeast and bacillus subtilis in a ratio of 10:5: 7.
A preparation process of microbial fermentation pig feed comprises the following specific process steps:
1) soaking barley flour, bran powder, corn cob powder and beans in water for 24-36 hr, adding fish powder and potato powder into the soaked materials, stirring, and adding appropriate amount of water to dilute to obtain dilute solution if the materials are thick;
2) adding a bacterium solution into the dilute solution obtained in the step 1), uniformly stirring, and carrying out aerobic fermentation for 6-8 hours to obtain an aerobic fermentation raw material solution;
3) pouring the aerobic fermentation raw material liquid obtained in the step 2) into a sealed fermentation tank for anaerobic fermentation for 5-7 days to obtain a microbial anaerobic fermentation feed;
4) heating and sterilizing the anaerobic fermented feed in the step 3) at 75-80 ℃ for 20-30 minutes to obtain sterilized fermented feed;
5) adding the vegetable and fruit juice into the sterilized fermented feed, uniformly stirring, and then adding sodium bicarbonate to obtain the microbial fermented pig feed.
In other embodiments of the present invention, the bacterial liquid is a mixed bacterial liquid of lactic acid bacteria, yeast and bacillus subtilis.
According to the invention, the raw materials are rich in nutrition, cheap and sufficient in market supply, and are beneficial to large-scale production and processing, the raw material proportion of the feed can meet the nutritional requirements of pigs, and the fermented raw materials are more beneficial to the absorption of the pigs. Because the fiber contents of wheat flour, bran, corn cob powder, bean powder and the like are high, the prepared solution is directly fermented and is not beneficial to early-stage fermentation growth of bacterial liquid, therefore, the raw materials are soaked for softening and expansion, and then the easily soluble fish meal and potato powder are added for fermentation treatment. Aerobic fermentation is carried out firstly, then anaerobic fermentation is carried out, bacteria are grown and activated in the raw material liquid firstly, and then anaerobic fermentation metabolism is carried out. The fermentation cannot be continued after the fermentation is finished, otherwise, the fermentation is excessive, so that the feed smells and becomes sour, and the pigs cannot eat the feed. Therefore, it is necessary to sterilize the fermented feed. The vegetables and fruits can not stay for a long time at high temperature, or the nutritional ingredients of the vegetables and fruits can be damaged, so that the significance of adding the vegetables and fruits into the feed is not achieved.
