Preparation method of barren sow feed

Abstract

The invention provides a preparation method of a barren sow feed. The preparation method comprises the steps of crushing, drying, kneading and fermenting the upper part of broad bean leaves and broad bean straws, and uniformly mixing the well-fermented broad bean leaves and broad bean straws with corn, barley flour, silkworm chrysalis powder and premixing material. The feed prepared by adopting the method has acid fragrance and is good in palatability, good in quality and balanced in nutrients.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to a method for preparing feed for empty pregnant sows. Background technique [0002] The sows in the open period are different from the pregnancy and lactation period, and have relatively low requirements for feed, but the health and nutrition of the sows in the open period are equally important. There are many problems in the intensive breeding of sows, the most important ones are the following four points. First, conventional feed materials such as corn and soybean meal are used as the main raw materials of sow feed. Increased costs. At the same time, unconventional feed is cheap and rich in resources, but the digestibility of unconventional feed raw materials is low, and there are anti-nutritional factors, so that the utilization of unconventional feed raw materials is obviously insufficient, and there is even a phenomenon of waste and discarding. Second, in order to prevent ...

Problems solved by technology

There are many problems in the intensive breeding of sows, the most important ones are the following four points. First, conventional feed materials such as corn and soybean meal are used as the main raw materials of sow feed. Increased costs

At the same time, unconventional feed is cheap and rich in resources, but the digestibility of unconventional feed raw materials is low, and there are anti-nutritional factors, so that the utilization of unconventional feed raw materials is obviously insufficient, and there is even a phenomenon of waste and discarding

Second, in order to prevent breeding sows from being overweight due to eating conventional concentrated feed, the limited dry feeding feeding technology usually used makes sows lack vitamins and cellulose and other elements, often leading to intestinal diseases such as sow constipation, which seriously restricts improving sow health and farrowing performance

At the same time, due to feed third, the mildew of feed raw materials leads to the enrichment of mycotoxins in sow feed and the infection of bacteria, which often leads to disordered reproduction of sows and low survival rate of piglets. The average number of piglets provided per sow in my country is about 15 per year. far lower than the 25 in developed countries

4. Sows in the empty pregnancy period generally add an appropriate amount of green feed rich in vitamins and cellulose, but the green feed cannot be stored for a long time and cannot be provided in the sow’s diet. Although some cabbage, carrots and other vegetables can be fed, the cost is relatively high

Although this feed reduces the cost to a certain extent, it is still a conventional feed with corn and bran as the main raw materials, and some green feed is not provided. The problems of sow feeding described above need to be further improved

Moreover, the chicken manure should be processed in time, otherwise it will be corrupted, and there are parasites and parasite eggs in the chicken manure, a large number of which will affect the intestinal health of pigs
