Compound mixed feed for pigling

Abstract

The invention relates to a compound mixed feed for pigling which fundamentally overcomes the problems of great addition amounts of inorganic trace elements copper and zinc and great discharge quantity of phosphorus. The compound mixed feed comprises the following components by weight: 650.0 to 680.6 parts of corn, 190 to 220 parts of soybean meal, 25 to 40 parts of wheat bran, 25 to 30 parts of cane sugar, 20 to 40 parts of fish meal, 5 to 8 parts of stone flour, 8 to 12 parts of soybean oil, 8 to 12 parts of calcium hydrogen phosphate, 3.0 to 3.5 parts of sodium chloride, 1 to 1.5 parts of choline chloride, 4 to 6 parts of a composite acidifying agent, 0.6 to 0.8 part of methionine, 3.5 to 4 parts of lysine hydrochloride, 1 to 1.3 parts of threonine, 0.26 to 0.34 part of tryptophan, 0.15 to 0.17 part of phytase, 0.9 to 1.1 parts of a trace mineral premix, 1.0 to 1.1 parts of a vitamin premix, 0.4 part of probiotics for pigs and 0.19 part of 10% colistin sulfate, wherein the enzyme activity of the phytase is 5000 U / g. The compound mixed feed is reasonably designed, increases daily gain, reduces a feed-meat ratio and the discharge amounts of trace elements and phosphorus in manure and improves economic benefits of enterprises.

Description

technical field [0001] The invention relates to a feed for piglets, in particular to a combined compound feed for piglets which is reasonably formulated after adding organic trace elements copper, zinc and phytase. Background technique [0002] In recent years, with the continuous expansion of the breeding scale, the number of pig breeding has increased year by year, and the pressure of environmental protection has become greater and greater. The pollution of the pig industry mainly includes harmful substances such as nitrogen, phosphorus, and trace elements. Among them, trace elements mainly come from excessively added and undigested inorganic trace elements in feed, such as copper and zinc. These harmful substances not only destroy the breeding environment, but also affect the health of pigs and reduce economic benefits. At the same time, harmful substances have affected the soil, water, and air, and have also caused harm to human health. The content of corn and soybean ...

Problems solved by technology

Although this patent uses inferior powder to reduce the content of corn and soybean meal, and is equipped with compound microbial preparations, although the cost of feed production is reduced, due to the use of secondary powder, the trace elements and phosphorus elements in the feed cannot be effectively absorbed, resulting in environmental pollution

[0004] Patent CN 101904442 B discloses "a compound feed for first-born lactating sows", which is composed of corn or puffed corn, wheat or puffed wheat, soybean meal, stone powder, calcium hydrogen phosphate, salt, compound multidimensional for lactating sows containing carrier, and lactating sow containing carrier The sow is made of compound multi-mineral and auxiliary materials, and its weight ratio is 50-650g / kg of corn or puffed corn or the mixture of the two, 50-650g / kg of wheat or puffed wheat or the mixture of the two, and 100-300g / kg of soybean meal , stone powder 8-18g / kg, calcium hydrogen phosphate 10-28g / kg, salt 3-6g / kg, compound multidimensional 8-12g / kg containing carrier lactating sows, compound multi-mineral 8-12g / kg containing carrier lactating sows and auxiliary materials, the patented formula is too complex and lacks the necessary absorption-promoting ingredients, so that the trace elements and amino acids in the feed cannot be effectively utilized, resulting in serious environmental pollution
