Pig feed for improving pig immunity

Abstract

The invention provides a pig feed for improving immunity, every 100kg of the pig feed comprises the following components by mass: 0.1-0.5kg of mango leaves extract; 50-60kg of corn flour; 10-15kg of soybean meal; 2-5kg of wheat bran; 5-7kg of rapeseed cake; 2-5kg of lima bean; 1-3 parts of blood meal; 3-6 parts of silkworm chrysalis; 0.1-0.5kg of methionine; 0.1-0.2kg of lysine; 0.005-0.01kg of oxytetracycline; 0.02-0.03 part of copper sulfate; 0.01-0.02 part of ferrous sulfate; 0.01-0.02 part of zinc sulfate; 0.1-0.5kg of calcium hydrogen phosphate; 0.03-0.06kg of vitamin C; and 0.1-0.5kg of salt. The pig feed is selective in the type and content of the materials, and especially definite in the content of the mango leaves extract, so that the feed nutrients collocation is reasonable, and the feed is suitable for pig digestion and absorption, enables the pig growth rate to be significantly increased, and can improve the immunity of the pig, and increase food safety of pork.

Description

[0001] technical field [0002] The invention belongs to the field of pig feed, in particular to a pig feed for improving immunity. Background technique [0003] Mango enjoys the reputation of "King of Tropical Fruits" and is deeply loved by people. In recent years, the world's mango industry has developed rapidly. China's mango production areas are mainly distributed in Hainan, Guangdong, Yunnan, Guangxi, Taiwan, southern Fujian, Guizhou, and river valleys at the southern end of Sichuan. The annual output of mangoes in Hainan, Guangdong, and Guangxi is about 200,000 tons, which is the main source of local agricultural economy. One of the important supporting industries for development. China's mango leaves are rich in resources, low in price, widely distributed in regions, and have the advantages of being harvested in four seasons; mango leaves are rich in mangiferin, isomangiferin, ascorbic acid, tannin, ellagic acid, α -Catechin, shikime, quinic acid, kaempferol, L- α ...

Problems solved by technology

However, in order to improve the breeding efficiency, farmers feed high-energy and high-protein feeds to make them grow rapidly, while ignoring the physical health problems of pigs. Often when diseases come, many farmers often use a large amount of antibiotics and chemicals to avoid more losses. Synthetic drugs and high-dose vaccines are used as prevention and treatment options, which not only increase the cost, but also impair immune function due to the extensive use of antibiotics, weaken immunity, increase stress response, and increase the burden on the body. health risks
