Problems solved by technology

[0005] At present, most biologically fermented feed products on the market are fermented by the mixed fermentation of lactic acid bacteria, spores and yeasts. Due to the different optimum fermentation conditions of different strains, the production process of mixed bacteria fermentation is not easy to control, and the product stability is low; and yeast and spores During the process of bacterial aerobic fermentation, part of the energy will be discharged in the form of heat and carbon dioxide, which will reduce the overall energy level of the fermented feed, thereby reducing the energy intake of animals, affecting the feed-to-meat ratio of the fermented feed, and reducing economic benefits

Embodiment 1

[0027] 30% of water, 21% of sugar beet meal, 11% of rice husk powder, 6% of sunflower meal, 3% of rice bran meal, 5% of soybean meal, 1% of soybean hull, 0.5% of calcium hydrogen phosphate, 21.5% of wheat bran, 0.5% of refined salt Mix and stir evenly, add 0.5% lactic acid bacteria powder at the same time, mix and stir evenly, put into a breathing bag with a one-way breathable valve, and ferment at 33°C for 70h.

[0028] Wherein, in the lactic acid bacteria powder, the weight ratio of Lactobacillus plantarum, Enterococcus faecium, Pediococcus lactis, Lactobacillus rhamnosus and Lactobacillus casei is 1:1:1:1:1.

[0029] test one

[0030] The experiment selected 23 sows with similar parity, body weight and backfat thickness. The test started 7 days before the expected farrowing date and was divided into 3 treatments, each treatment had 7-9 repetitions, and each repetition had 1 sow. The experiment was completed at 22 days after weaning of piglets. The control group was fed th...

Abstract

The invention discloses a fermented feed for sows at the lactation period. The fermented feed is obtained by fermenting the following raw materials in percentage by weight: 30-50% of water, 5-30% of beet pulp, 3-20% of rice husk powder, 5-45% of wheat bran, 1-10% of sunflower meal, 3-15% of rice bran meal, 1-5% of soybean meal, 2-10% of soybean hulls, 0-1% of dicalcium phosphate, 0-0.6% of salt and 0.001-0.5% of lactic acid bacterium powder, wherein the lactic acid bacterium powder is a mixture of lactobacillus plantarum, enterococcus faecium, pediococcus acidilactici, lactobacillus rhamnosusand lactobacillus casei, the weight ratio of the five bacteria is 1 to (0.5-2) to (1-1.5) to (1-2) to (1-2.5), and the total number of lactic acid bacteria is higher than 10<9>CFU / g. Through the adoption of the fermented feed disclosed by the invention, the food consumption of the sows can be increased, constipation can be relieved, the proportion of fetal death can be reduced, the growing performance of piglets can be improved, and the economic benefits of a piggery can be increased.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a fermented feed for lactating sows. Background technique [0002] In pig farming, more and healthier piglets from sows are key to a successful farm operation. There is an inevitable relationship between litter size and the nutritional status and health status of sows. The nutritional health status of sows significantly affects physiological processes such as fertilization, embryo implantation, and embryonic development, and these physiological processes are the main factors affecting litter size. In modern pig farms, sow constipation is a stubborn problem that plagues the majority of pig producers in production management. According to statistics, about 60% of sows have constipation. The clinical symptoms are decreased feed intake, depression, difficulty in defecation, and dry and hard fecal balls in sows. In particular, sows with constipation in the early stage of delivery will...
