Fattening pig feeds and preparation method thereof

Abstract

The invention relates to fattening pig feeds and a preparation method thereof. The fattening pig feeds are prepared from the following components in parts by weight: 80 to 90 parts of basal feeds, 7 to 15 parts of a traditional Chinese medicament, 3 to 5 parts of a probiotic agent and 0.05 to 0.1 part of a vitamin complex. The probiotic agent is prepared by a method comprising the following steps: (1) preparing a medical stone extracting solution: weighing and crushing medical stones to 150 to 200 meshes, adding water according to a material-liquid ratio of 1 gram of medical stones to 100 to 150 milliliters of water, performing high-pressure cooking for 2 to 3h, and filtering to obtain filtrate and filter residues; (2) uniformly mixing 30 to 40 parts by weight of bran, 20 to 30 parts by weight of corn flour, 10 to 15 parts by weight of straw powder, 10 to 15 parts by weight of rice husks and 5 to 8 parts by weight of the filter residues obtained in step (1), regulating the water content to be 30 to 50 percent by virtue of the filtrate obtained in step (1), and sterilizing to obtain an activated culture medium; (3) inoculating probiotics to the activated culture medium according to an inoculation amount of 10 to 15 percent, and culturing for 2 to 3 days at 30 to 37 DEG C; (4) adding 5 to 10 parts by weight of xanthan gum into the culture medium in which the probiotics are cultured, uniformly mixing, then granulating and drying to obtain the probiotic agent. According to the fattening pig feeds, the feed conversion rate can be effectively increased.

Description

technical field [0001] The invention relates to a fattening pig feed and a preparation method thereof, belonging to the field of pig feed. Background technique [0002] my country is one of the largest breeding countries in the world. In my country's breeding industry, pig breeding accounts for a large proportion, which drives the rapid development of the feed industry. At present, there are various kinds of pig feeds on the market. Pigs of different growth stages There are specific feeds. Most of the existing pig feeds are supplemented with antibiotics. Although the pig feeds with antibiotics can achieve better feeding effects, it is followed by problems of drug residues, drug resistance of pathogens, and environmental problems. , the imbalance of normal flora in the digestive tract of livestock and poultry, the decline of immune function of livestock and poultry, and the serious drug residues in pigs, which seriously damage the health of pigs and humans. As many problems ca...
