Antibiotic-free fermented feed for pregnancy sows and preparation method of antibiotic-free fermented feed

Abstract

The invention relates to the field of pig feeds, in particular to an antibiotic-free fermented feed for pregnancy sows and a preparation method of the antibiotic-free fermented feed. The antibiotic-free fermented feed comprises the following components in parts by weight of 500-630 parts of corn, 100-150 parts of soybean meal, 20-60 parts of fermenting raw materials, 100-200 parts of soybean hulls, 8-20 parts of dicalcium phosphate, 5-15 parts of soybean oil, 10-20 parts of stone powder, 1-5 parts of composite amino acids, 1-5 parts of composite multiple vitamins, 1-5 parts of minerals, 2-8 parts of sodium chloride, 0.5-1 part of choline chloride, 1-4 parts of enzyme preparations, 0.2-1.4 parts of plant extracts, and 0.4-1.8 parts of microecological preparations. According to the antibiotic-free fermented feed for pregnancy sows and the preparation method of the antibiotic-free fermented feed disclosed by the invention, the antibiotic-free fermented feed is a safe environmental-friendly healthy antibiotic-free feed; the application method is used for cooperation, and the pregnancy sows are fed, so that solving the problem of propagation of the sows in a present large-scale piggeryis facilitated, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the field of animal feed, and in particular relates to a high-efficiency and environment-friendly fermented feed for pregnant sows that can realize no addition of antibiotics. Background technique [0002] Today's pig industry has entered the era of large-scale specialization. For a large-scale pig farm, raising sows is the most important thing, and it is the key link to bring benefits to the farm. Improving the quantity and quality of offspring is a manifestation of the high efficiency of a sow. However, in large-scale pig farms, there are many reproductive obstacles such as miscarriage, stillbirth, insufficient postpartum milk, and low survival rate of suckling piglets. Both will cause huge economic losses. [0003] There are two main aspects to solving the problem of reproductive disorders. One is the problem of bacterial and viral diseases. Disease problems can be prevented and controlled by vaccines and drugs. The second...

The second is feed nutrition problems, manifested in constipation in pregnant sows, toxin poisoning and nutrients that cannot maintain high reproductive performance of sows, etc.

Constipation in sows can cause increased endotoxins, leading to fever, stillbirth and miscarriage. In order to prevent constipation in pregnant sows, it is necessary to add more fibrous raw materials to their feed, such as bran, soybean skin, grass powder, etc., but Excessive intake of such raw materials will cause toxin accumulation, which will cause toxin poisoning in sows, causing problems such as miscarriage, weak piglets, and poor milk in sows
