Special feed for sows from 95 days of pregnancy to delivery periods

Abstract

The invention discloses special feed for sows from 95 days of pregnancy to delivery periods. The raw materials of the feed include, by weight, 180-200 parts of a main ingredient, 5-9 parts of linoleicacid, 2-3 parts of calcium formate, 0.06-0.1 part of complex trace elements, 0.2-0.4 part of multi-vitamins, 40-45 parts of an immune enhancer, 0.2-0.4 part of zinc phenylalanine, 0.2-0.4 part of ferric compound amino acid complex, 0.2-0.4 part of a probiotic preparation 2-4 parts of an intestinal peristaltic agent, 4-8 parts of calcium hydrogen phosphate, 1-2 parts of salt, 2-4 parts of stone powder, 0.4-1 part of phenylalanine, 0.2-0.4 part of tryptophan, and 0.2-0.3 part of valine. The preparation technology of the intestinal peristaltic agent includes: mixing locust bean gum, montmorillonite, monoglyceride and water; performing warming and stirring; adding sweet potato starch and uniformly mixing the mixture; performing warming and pre-gelatinization; performing cooling; adding grapeseed oil and fructo oligosaccharide and stirring the mixture; and obtaining the intestinal peristaltic agent through spray drying.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a special feed for sows from 95 days of pregnancy to farrowing. Background technique [0002] At present, in the pig industry, the production performance of sows is the most important thing to reflect the breeding level of a farm. From 95 days after pregnancy to delivery, the changes of hormones in sows are very complicated, and the changes of hormones directly affect It is the key point of the whole reproductive cycle, which affects the ovulation and embryo survival rate. The period from 95 days after pregnancy to delivery directly affects the stability of embryo implantation. [0003] At present, the feed for pregnant sows is fed before 95 days of pregnancy, the protein is about 14%, the dietary fiber level is less than 3%, and the feed types are limited to corn, peanut meal, wheat, and bran. The consequences of this are: the types of nutrients in the feed are too few, and the t...

Problems solved by technology

The consequences of this are: the types of nutrients in the feed are too few, and the trace nutrients are too low, which cannot accurately meet the nutrient requirements of sows after 95 days of pregnancy, resulting in the lack of nutrients in sows during pregnancy, which is not conducive to the intestinal health of sows , thereby reducing embryo survival in sows
