High-fiber feed for sows as well as preparation method and application of high-fiber feed

Abstract

The invention relates to a high-fiber feed for sows as well as a preparation method and application of the high-fiber feed. The high-fiber feed for sows comprises the following raw materials in partsby weight: 50-70 parts of corn, 10-18 parts of soybean meal, 0-20 parts of wheat bran, 0-15 parts of puffing soybeans, 0-4 parts of fish meal, 0.5-1.5 parts of stone powder, 0.5-1.5 parts of calcium hydrogen phosphate, 0.3-0.5 part of table salt, 0.5-1.5 parts of a premix, and 0.5-5 parts of cellulose, wherein the content of crude fibers in the cellulose is greater than or equal to 60%, the content of neutral washing fibers is greater than or equal to 86%, the content of acidic washing fibers is greater than or equal to 70%, the swelling property of the feed is greater than or equal to 5.0mL / g, and the retention ability is greater than or equal to 5.0g / g. The invention further relates to the preparation method and application of the high-fiber feed for sows. The high-fiber feed for sows has the advantages that the satiety of the sows at the gestation period can be strengthened, the material benefits of the sows are improved, the generation of stress and avoidance behaviors caused by restricted feeding is reduced, the intestinal flora is promoted to be balanced, the intestine health status and the reproductive performance of the sows are improved, the survival rate of piggies afterbeing weaned is increased, the growth of the piggies is promoted, and the interval time of the sows from weaning to rutting is shortened.

Description

Technical field [0001] The invention relates to a feed and a preparation method and application thereof, in particular to a high-fiber sow feed and a preparation method and application thereof. Background technique [0002] In large-scale pig farms, abnormal behavior and constipation in sows are very common. Excessive energy intake of pregnant sows can lead to dystocia, reduce embryo survival, and reduce feed intake and lactation during lactation. In order to reduce this loss, pregnant sows are often restricted in feeding. Since the amount of feed provided by restricted feeding is only 40% to 60% of the ad libitum intake, sows are prone to abnormal behaviors such as pen biting and false chewing. These behaviors will increase the metabolic rate, reduce the feed conversion efficiency, and affect the mother. Pork reproductive performance is unfavorable. The main clinical symptoms of constipation in sows are difficulty in defecation, reduced defecation frequency, dry stool, loss of...

Problems solved by technology

At present, common sources of cellulose include conventional feed materials such as wheat bran, bean hulls, beet pulp, and corn bran, but the fiber content in these crude fiber raw materials is relatively low (for example, the crude fiber content in bran generally does not exceed 10%). When the amount is high, it will easily lead to poor feed palatability; and the insoluble fiber in these raw materials is difficult to be fermented, and these raw materials are also easily contaminated by mycotoxins, which will affect the reproductive performance of sows

For example, CN106819478A discloses a mixed feed that can be used to improve constipation in sows, wherein 96 to 99 parts of fiber carrier, 0.3 to 3 parts of xylooligosaccharide and 0.5 to 1.0 part of Enterococcus faecium are added, and the fiber carrier is selected from From one or more of bran, apple pomace, sugar beet meal, alfalfa grass particles, and soybean hulls, the fiber content of the fiber carrier in this invention is low, and it is not easy to be fermented, the utilization rate is low, and it needs to be combined with wood oligosaccharides. sugar and Enterococcus faecium to jointly promote the intestinal tract of sows and relieve constipation of sows, the cost is high
