Embodiment 1
[0021] Pig fattening feed (mass percentage): corn 65%, soybean meal 24%, bran 11%; the above ingredients are used as the main material, and 0.01-0.05 mass percentage of weed and yeast selenium 0.03 are added.
[0022] 1200kg of the above-mentioned feed is prepared and fed to 5 adult pigs with a weight of 27-30kg, 3 meals a day, 1.5-2.8kg per meal. After 100 days of consumption, the weight of the adult pigs is 110-120kg. During this period, the adult pigs were observed: red and shiny skin, no moss spots on the skin, long sleep time, obvious growth rate, strong muscles, loose and delicate feces, and low discharge volume and no odor.
[0023] For pigs after slaughter, the color of the pork is bright red, that is, the water is good, which can effectively extend the shelf life to more than 16 hours, improve the meat quality and taste, and the pork entrance is refined and tender. And the content of selenium in pork, after testing, the content of selenium reaches 5ppm / kg.
Embodiment 2
[0025] Pig fattening feed (mass percentage): corn 60%, soybean meal 28%, bran 12%; the above ingredients are used as the main material, and 0.01-0.05 mass percentage of selenium and yeast selenium 0.03 are added.
[0026] 1200kg of the above-mentioned feed is prepared and fed to 5 adult pigs with a weight of 27-30kg, 3 meals a day, 1.5-2.8kg per meal. After 100 days of consumption, the weight of the adult pigs is 110-120kg.
[0027] The above-mentioned adult pigs eat this feed, and its effect is similar to that of Example 1.

Abstract
The invention discloses a feed for fattening adult pigs. In the feed, corns, bean pulp and bran are mainly used as the main materials. The feed is characterized in that 0.01-0.05 percent by mass of graceful jessamine herb and 0.03 percent by mass of selenium yeast are also added in the main materials. When the feed is in animal bodies, the added selenium yeast is a necessary ingredient of glutathione peroxidase and 5-deiodinase and is also an ingredient of various proteins in the animal bodies and has important effects on oxidation resistance, stress resistance, improvement of immunity and the like of the animal bodies. Areas with selenium content of less than 0.05mug/g in feed forage belong to selenium deficiency areas. However, in China, about two thirds of areas belong to the selenium deficiency areas, and thus, selenium supplementation has the important significance on animal reproduction in China.
Description
technical field [0001] The invention relates to a pig feed, in particular to a feed mainly composed of corn, soybean meal and bran. Background technique [0002] There are harmful pathogenic microorganisms and some beneficial microorganisms in animals. While killing and inhibiting pathogenic microorganisms in animals, antibiotics also kill and inhibit beneficial microorganisms, thereby disrupting the pattern of mutual restraint between microbial flora and destroying the ecological balance of microorganisms, resulting in digestive disorders. Caused various digestive tract diseases, such as chronic diarrhea. [0003] Antibiotics make pathogenic microorganisms resistant to drugs. While antibiotics are antibacterial in animals, it is possible to mutate some pathogenic microorganisms and become drug-resistant strains, so that the entire pathogenic microorganisms gradually change towards the direction of drug resistance. After these drug-resistant pathogenic microorganisms mult...
