Problems solved by technology

However, this method is not only labor-intensive and cumbersome to operate, it is not suitable for large-scale farms, and because the added water is difficult to guarantee, sometimes it will aggravate the stress of piglets at weaning, resulting in diarrhea in piglets

Embodiment 1

[0015] Suckling pig feed formula (%): corn 57, soybean meal 20, full-fat puffed soybean 10, whey powder 5, fish meal 4, calcium hydrogen phosphate 2;, stone powder 0.7, salt 0.3, sodium dehydroacetate 0.03, zeolite powder 0.97 . The nutritional indicators of the feed are: crude protein 20%, calcium 0.9%, available phosphorus 0.5%, lysine 1.3%, sulfur-containing amino acids 0.8%, digestible energy 3300KC / kg.

[0016] Using a single-screw extruder as the main processing equipment, crush soybean meal, fish meal, corn and other raw materials through a 60-mesh sieve, weigh the crushed raw materials according to the above formula, add water until the water content of the feed reaches 30 %, the barrel temperature in the kneading zone of the extruder is 120°C±5°C, the barrel temperature in the cooking zone of the extruder is 60°C±5°C, the screw speed is 300r / min, the die hole is 2.5mm, and the opening rate is 30 The degree of gelatinization of the semi-moist suckling pig feed after e...

Abstract

The invention relates to a production method for a semi-humid porket feed belonging to the pig feed processing technical field. The invention is a general weaned piglets feed: the raw materials is dry powder feed and solid particle feed; after being crushed, sieved and weighed, fungicide and quantitative water are added in the raw materials, and then are blended with a water content of 25 percent to 55 percent; the semi-humid porket feed is made by extruding, refrigerating and packing the particles; when the extrusion method is used for the production, an extruder with a kneading area temperature of 80 DEG C to 150 DEG C, a cooling temperature of 50 DEGC to 100 DEG C, and an extrusion condition of the screw speed of 200 -1000r/min is adopted for producing the semi-humid porket feed with a starch gelatinization of 75 percent to 90 percent. Preservative with a certain concentration is added into the feed formula, so that the semi-humid porket feed will not mildew within 6 months.

Description

technical field [0001] The invention discloses a method for producing semi-moist sucking pig feed, which belongs to the technical field of pig feed processing in agriculture. Background technique [0002] Early weaning can shorten the lactation time of sows, thereby increasing the fecundity and annual litter size of sows, improving the utilization rate of farrowing, reducing the production cost of piglets, and blocking the spread of certain infectious diseases. the trend of. However, early weaning is relatively stressful to piglets, and these weaning stresses include nutritional stress, environmental stress, and fighting stress. [0003] In order to eliminate or alleviate this kind of weaning stress, improve the health status of piglets, and improve production performance, people have done a lot of research on improving the quality of piglet starter in terms of feed nutrition, feeding methods, feeding times and flavoring agents for a long time, but Relatively little resear...
