Feed for lactation sows and preparation method of feed

Abstract

The invention relates to the technical field of preparation of an animal feed, in particular to a feed for lactation sows and a preparation method of the feed. The feed comprises corn, soybean oil, soybean meal, puffed soybeans, brown sugar, glucose, fermented soybean meal, fish meal, dicalcium phosphate, stone powder, salt, sodium bicarbonate, choline chloride, lysine, methionine, phytase, molasses, a premix feed and feed raw materials rich in soluble fibers. The raw materials mutually cooperate and jointly act under specific composition. In the feed, the brown sugar, the glucose, the molasses, the corn and the soybean oil are used as energy feeds; the soybean meal and the fish meal are main sources of the lysine; and the fish meal, the dicalcium phosphate, the phytase, the salt, the stone powder and the premix feed provide calcium, phosphorus, sodium, vitamins and trace elements. In the feed, the raw materials achieve the effects of increasing the food consumption of the lactation sows, reducing the constipation possibility of the lactation sows, shortening the time interval of the lactation sows from weaning to oestrus, increasing the weaned survival rate of piglets, and increasing the weight of the weaned piglets.

Description

technical field [0001] The invention belongs to the technical field of animal feed preparation, and in particular relates to feed for lactating sows and a preparation method thereof. Background technique [0002] In modern large-scale farms, decreased feed intake and constipation of lactating sows are important problems that have plagued farmers for a long time. Lactating sows weaken their physique due to reduced feed intake, resulting in too long delivery time, which increases the stillbirth rate, reduces the milk production and ovulation volume of sows, prolongs the time interval from weaning to estrus, and delays the sow's birth rate. At the same time, the reduction of milk production will also hinder the growth and development of piglets, making weaned piglets have many problems such as small weight, easy disease, and low survival rate. In addition, in recent years, it has been found that lactating sows have common constipation. Due to long-term constipation, lactating ...

Problems solved by technology

For example, Chinese patent document CN102870977A discloses a kind of secondary flour-corn type compound feed for lactating sows, the raw materials of this feed are as follows: corn, secondary flour, biscuit flour, wheat bran, soybean meal, chocolate, fish meal, wheat protein, soybean flour , premix I, premix II, compound microbial inoculum, wherein, compound microbial inoculum includes enterococcus, yeast and bacillus; premix I includes: rice husk powder, zeolite powder, vitamin E, wood Glycanase, phytase, carnitine, calcium hydrogen phosphate, multivitamins, among which multivitamins include: VA, VD3, VK3, VB1, VB2, VB6, VB12, VE50, nicotinamide, calcium pantothenate, biotin, α- One or more of lipoic acid and folic acid; the premix II includes: rice husk powder, zeolite powder, organic chromium, stone powder, choline, salt, lysine, threonine, valine, methionine , composite minerals, magnesium sulfate, potassium chloride, described composite minerals include anhydrous copper sulfate, ferrous sulfate monohydrate, zinc sulfate monohydrate, manganese sulfate monohydrate, potassium iodide, sodium selenite, cobalt chloride One or more of them; the above-mentioned compound feed can increase the milk yield of lactating sows, reduce the time of estrus again after weaning, increase the feed intake during lactation and reduce the constipation of lactating sows, but the survival rate of weaned piglets and the The lower body weight is not conducive to the growth and reproduction of piglets, which seriously affects the economic benefits of the farm
