Problems solved by technology

These nitrogen and phosphorus deposits in the soil or infiltrate directly into groundwater or flow into rivers and lakes through surface soil loss will lead to eutrophication of water and accelerate the excessive growth of aquatic plants, especially algae, resulting in significant deterioration of water quality and causing huge pollution to the environment.

Embodiment 1

[0011] The compound feed for reducing the nitrogen and phosphorus excretion of growing pigs provided in this example is made by mixing the following components in mass percentage: 67.36% corn, 2.35% rice bran, 6% bran, 19% soybean meal, stone powder 1.5%, calcium hydrogen phosphate 0.3%, salt 0.3%, lysine 0.45%, methionine 0.15%, threonine 0.14%, soybean oil 1.5%, pig multidimensional 0.05%, phytase 0.1%, compound enzyme preparation 0.1% , Premix 0.7%.

Embodiment 2

[0013] The compound feed for reducing the nitrogen and phosphorus excretion of growing pigs provided in this example is made by mixing the following components in mass percentage: 66.55% corn, 3.6% rice bran, 5% bran, 19% soybean meal, stone powder 1.5%, calcium hydrogen phosphate 0.4%, salt 0.3%, lysine 0.44%, methionine 0.14%, threonine 0.12%, soybean oil 2%, pig multidimensional 0.05%, phytase 0.1%, compound enzyme preparation 0.1% , Premix 0.7%.

Embodiment 3

[0015] The compound feed for reducing the nitrogen and phosphorus excretion of growing pigs provided in this example is made by mixing the following components in mass percentage: 62.97% of corn, 5% of rice bran, 5.3% of bran, 20% of soybean meal, stone powder 1.4%, calcium hydrogen phosphate 0.5%, salt 0.3%, lysine 0.43%, methionine 0.1%, threonine 0.1%, soybean oil 3%, pig multidimensional 0.05%, phytase 0.1%, compound enzyme preparation 0.05% , Premix 0.7%.

[0016] The premixes in Embodiment 1-Example 3 are all prepared by themselves, containing 2.00g of copper, 10.00g of zinc, 10.00g of iron, 0.400g of manganese, 27.64mg of iodine, 30.18mg of selenium, sulfuric acid viscose in every kilogram of premix. 50 g of mycocin, 50 g of salinomycin aqueous solution with a mass percent concentration of 10%, and the bran of the remainder.

Abstract

The invention discloses a compound feed for reducing nitrogen and phosphorus excretions of growing pigs, comprising the following components in percentage by weight: 61-69% of corn, 2-5% of rice husk, 4-6% of bran, 18-25% of bean pulp, 0.5-1.5% of mountain flour, 0.3-0.6% of calcium hydrophosphate, 0.3-0.5% of salt, 0.35-0.45% of lysine, 0.1-0.15% of methionine, 0.1-0.14% of threonine, 1-3% of bean oil, 0.01-0.05% of swine multidimensional, 0.05-0.1% of phytase, 0.05-0.1% of complex enzyme preparation and 0.7% of premix. Through reasonable match of all the components, the compound feed increases the utilization rate of nutrients such as nitrogen, phosphorus and the like, obviously reduces the nitrogen and phosphorus excretions of the growing pigs and plays a positive role for the improvement of an ecological environment.

Description

technical field [0001] The invention relates to the technical field of pig feed, in particular to a compound feed for reducing nitrogen and phosphorus excretion of growing pigs. Background technique [0002] my country is a big pig raising country. According to statistics, in 2006, 612 million live pigs were sold in my country, and in 2007, 565 million commercial pigs were sold. In 2010, the number of live pigs sold reached 730 million. The rapid development of the pig industry has played a huge role in improving people's living standards and promoting the development of rural local economies, but at the same time, the sewage produced by a large number of large-scale pig farms directly affects the surrounding ecological environment. Pig farm pollutants are mainly nitrogen, phosphorus and other substances in feces. According to research, a small pig can produce 1500kg of feces and urine per year, while medium pigs can produce 3000kg of feces and urine per year, and large pig...
