Abstract

The invention provides a concentrated feed for a pregnant sow, which mainly comprises the following raw materials by weight percentage: 58 portions of soybean meal (46%), 10 portions of rapeseed meal, 10 portions of beer yeast powder, 9 portions of corn gluten feed, 3.75 portions of calcium hydrogen phosphate, 4.00 portions of stone powder, 1.70 portions of common salt, 0.5 portions of choline, 2.5 portions of core material specially used for pregnant sow, 0.50 portions of saleratus, 0.40 portions of montmorillonite and 0.05 portions of propionate mould inhibitor. The method comprises the following steps: selecting the raw materials by proportion, magnetically selecting the components, crushing the components, weighing the components by an electronic steelyard, automatically compounding, mixing and stirring the components, detecting the quality, separating, weighing and packaging the components respectively, thus obtaining the product. When in use, the concentrated feed for the pregnant sow is mixed with the self-prepared coarse material containing rice bran, green fodder and the like to feed the pregnant sow, wherein the proportion between the concentrated feed and the coarse material is 2:8; therefore, the full nutrition of the pregnant sow and the piglet can be satisfied, the farrowing rate of the sow and the livability of the piglet are improved, and about 12 or 13 pigletscan be borne by each sow according to the feeding experience and no dead piglet exists basically.

Description

technical field [0001] The invention relates to the technical field of livestock feed industry, in particular to concentrated feed for pregnant sows. Background technique [0002] There are many kinds of concentrated feed in the existing pig feed. The feed ingredients and auxiliary materials produced by various manufacturers are similar, but their formulas also have their own characteristics. They are all set to meet the different reproductive characteristics of sows. For the requirements of the growth period, the traditional sow feed is fed with the concentrated feed of ordinary fattening pigs, which has no strong pertinence and cannot fully meet the comprehensive nutritional needs of pregnant sows. [0003] The concentrated feed for pregnant sows of the present invention is aimed at the physiological characteristics of sows raised in rural areas in mountainous areas during pregnancy, and has designed special nutritional trace element premixes, vitamin premixes, compound be...
