Technical Field

The invention belongs to the technical field of suckling pig feed, and particularly relates to antibiotic-free suckling pig nursing compound feed and a preparation method thereof.

Background

With the push of scientific pig raising, it is a trend to select specific feed for feeding according to the growth stage of suckling pigs. Dividing according to the day age and initial weight of the suckling pigs, wherein the day age of the suckling pigs is 21-35 days old, and the feed fed at the stage is called 'suckling pig creep feed'. The piglet 35-70 days old is called the nursery stage. In the piglet creep stage, the initial weight is small, the growth is fast, the feed conversion ratio in the stage is low, and the conversion is fast; the initial weight of the suckling pigs is generally more than 10 kg in the nursing stage, the suckling pigs in the nursing stage grow slower than in the creep stage, and the feed has higher feed meat ratio.

Currently, antibiotic-free feed is of interest to various countries, and in the seventies of the twentieth century the european union has begun to suspend approving the addition of several important antibiotics to animal feed at sub-therapeutic doses. In 1987, it was first proposed in sweden to disable growth-promoting antibiotics in the feed. Subsequently, countries with antibiotics banned are danish, germany, finland, and those banned with avomycin, tylosin, spiramycin and virginiamycin. The eu committee banned the use of avomycin in animal feed in 1997, and the eu minister committee banned the use of tylosin, spiramycin, bacitracin zinc and virginiamycin in animal feed in the end of 1998.

The european union has found that intensive poultry production without the use of growth-promoting antibiotics should improve the quality of barn feeding and management, while it is necessary to modify the feed composition, such as by adding enzyme preparations, probiotics, organic acid preparations and other functional additives, to improve the feed utilization and improve the health of the animals.

How to provide a nonreactive porket feed suitable for different growth stages of porkets becomes a research hotspot of various feed production enterprises.

Through search, many domestic enterprises have started research on antibiotic-free feed, and for example, the Chinese patent application CN201210412256.4 discloses a powdered suckling pig creep compound feed for antibiotic-free health care and a preparation method thereof, wherein the feed is prepared from the following raw materials: corn, broken rice, puffed corn flour, puffed soybean meal, peeled soybean meal, fermented soybean meal, white fish meal, flour, plasma protein powder, whey powder, fructose, dextrose monohydrate, soybean oil, calcium formate, monocalcium phosphate, table salt, an envelope slow-release acidifier, choline chloride, a suckling pig compound premix, zinc oxide, yeast cell wall polysaccharide, sodium glutamate, arazyme, lipase, clostridium butyricum, vegetable essential oil, L-lysine hydrochloride, and DL methionine; l-threonine, tryptophan and phytase. The invention adds high amino acid, clostridium butyricum and a plurality of plant essential oils into the feed, and simultaneously adds high-energy components to improve the feed intake, the weight growth rate and the like of the porket.

And for example, Chinese patent application CN200610123633.7 is an improved preparation method of the feed. The invention mainly processes all plant feed raw materials in the feed raw materials by adopting a puffing method. In addition, an acidifier, an enzyme preparation and a prebiotic (microecological preparation) are added in the preparation process as feed additives so as to improve the immunity of animals and the utilization rate of the feed.

The feed provided by the two patents is more suitable for feeding the suckling pigs in the creep stage, but cannot be directly used for the suckling pigs in the nursing stage with larger initial weight.
