Problems solved by technology

The production of compound feed generally goes through at least one high-temperature process, and heat-sensitive additives (enzyme preparations, vitamins, probiotics) will be partially ineffective or inactivated during the high-temperature process, resulting in insufficient effective additives in the compound feed; During the long-term storage process, the potency of the above nutrients will also be lost, resulting in the inconsistency between the nutritional supply of the feed and the design value

Embodiment 1

[0033] This example provides a dry-wet separation nursery pig feed production and processing method and semi-liquid feeding technology, the applicable object is 21 days weaned to the end of nursery piglets, the dry-wet separation nursery pig feed preparation method, Include the following steps:

[0034] (1) Selected high-quality corn and peeled soybean meal are transported to the hammer mill through the scraper conveyor for crushing until the particle size is 2.0mm; the crushed corn and soybean meal are mixed according to the ratio of 2:1, and are extruded Machine high-temperature puffing treatment, modulation temperature 95-105°C, puffing cavity temperature 120-140°C, starch gelatinization degree of puffed mixture 40-50%, urease activity lower than 0.2 [mg / (min·g) (as ammonium nitrogen ), carry out secondary crushing on the puffed corn, the crushed particle size is less than 1.5mm, and the crushed mixed material is put into the warehouse separately for later use;

Abstract

The present invention relates to a production method of a dryness and wetness separation feed for conservation pigs based on a semi-liquid state feeding technology. The production method specificallycomprises the following steps: the feed is manufactured by a dry base feed and a liquid nutritional package feed. The dry base feed is a basic granule compound feed free of enzyme preparations, vitamins and probiotics and the liquid nutritional package feed is a solution containing an organic functional additive after dilution; and when the dry base feed is fed, the dry base feed is combined withthe liquid nutritional package feed to form a semi-liquid feed for feeding by suckling pigs. According to physiological characteristics of the conservation pigs, the semi-liquid state feeding technology is used. After full verifications, the feed effectively solves weaning material-changing stress of the conservation pigs, is suitable for transitional use during weaning, and has obvious effects ofpromoting growth, helping digestion and preventing diarrhea of the conservation pigs. The production method is also not high in equipment requirements, simple to operate, low in costs, and suitable for large-scale promotion and use in pig farms.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a method for producing nursery pig feed based on semi-liquid feeding technology. Background technique [0002] Nursery pigs are piglets that are transferred from the farrowing room to the nursery after weaning, usually 21-25 days old. Due to long-term dependence on breast milk, the intestinal digestive system of piglets at this stage is not fully developed, and the beneficial microbial flora in the intestinal tract is still intact. Not established, poor immunity, weak constitution. The nutritional supply of suckling pigs transitions from liquid breast milk to solid feed. The traditional feeding method is to use creep feed (powder or granules) to guide the creep at weaning. For newly weaned piglets, the transition adaptation time is 7-10 days. Feed It is difficult to switch, and usually there will be food refusal or anorexia, weight loss instead of gain, physical decline, and signif...
