Feed production system and process for pregnant sow

Abstract

The invention relates to a feed production system and process for a pregnant sow. The feed production system comprises a material distributing bin, a first material mixing mechanism, a second materialmixing mechanism, a crushing mechanism, a conditioning mechanism and a forming mechanism, which are sequentially connected, and further comprises a material storage bin, wherein the material storagebin comprises a first sub-bin and a second sub-bin which is isolated from the first sub-bin; the first sub-bin is used for storing magnesium sulfate powder; a magnesium sulfate weighing mechanism is connected to an outlet of the first sub-bin; the magnesium sulfate weighing mechanism is provided with a magnesium sulfate feeding outlet and a magnesium sulfate recovery outlet; the magnesium sulfatefeeding outlet is connected with an inlet of the first material mixing mechanism; a magnesium sulfate recovery mechanism is connected to the magnesium sulfate recovery outlet; and an outlet of the second sub-bin is connected with an inlet of the material distributing bin. Compared with the prior art, the feed production system and process disclosed by the invention can separately and accurately control the addition of magnesium sulfate, and can improve the mixing uniformity of the magnesium sulfate in a feed, so that the number of living piglets born by the pregnant sow can be increased, the labor stage of the pregnant sow can be shortened, and the birth weight of each of the piglets is increased.

Description

technical field [0001] The invention relates to a feed production system, in particular to a feed production system and process for pregnant sows. Background technique [0002] With the scale of breeding industry and the rapid development of modern breeding technology, the role of sows in breeding is becoming more and more obvious. Studies have shown that the labor, feed and other costs required for mating and pregnancy of sows with 8 and 12 sows are similar, so more and stronger litters are the top priority in pig production . Existing feed for pregnant sows, its typical formulation components include base material and anti-constipation additive magnesium sulfate composed of corn, bran, soybean meal, stone powder, calcium hydrogen phosphate, salt, choline chloride and 1% premix, The weight ratio scope of each component is as follows: [0003] [0004] The feed for pregnant sows can meet the nutritional needs of sows in the early and middle stages of pregnancy, and can...

Problems solved by technology

And anhydrous magnesium sulfate is as a kind of dry reagent, very easy to absorb water and form the magnesium sulfate heptahydrate of white fine oblique shape or oblique columnar crystal, can't guarantee the dryness of each raw material in the feed in actual production, after adding anhydrous magnesium sulfate, easy Absorption of water to form crystals, which is the main cause of excess magnesium sulfate in topical feeds
