Nitrogen-phosphorus copper-zinc emission-reduction eco-friendly middle-stage pig compound premix feed

Abstract

A nitrogen-phosphorus copper-zinc emission-reduction eco-friendly middle-stage pig compound premix feed consists of raw materials by weight percentage: 0.616% of ferrous sulfate monohydrate, 0.308% of iron glycine, 0.611% of blue copperas, 0.123% of copper mothionine, 0.534% of zinc sulphate monohydrate, 0.18% of zinc methionine, 0.658% of manganese sulfate monohydrate, 0.013% of 1% sodium selenite premix, 0.012% of 1% cobalt chloride premix, 7.5% of sodium chloride, 5% of L-lysine, 2% of methionine, 1% of threonine, 0.8% of compound vitamin, 2.5% of compound enzyme, 1% of red skin pigment, 41% of mountain flour, 15% of calcium hydrogen phosphate, 2% of phytase, 0.05% of calcium propionate, 10% of zeolite powder, 8.795% of mixture of rice chaff and husk, and 0.3% of olaquindox. By changing the adding proportions of the L-lysine, the methionine, the threonine and the like, after the nitrogen-phosphorus copper-zinc emission-reduction eco-friendly middle pig compound premix feed provided by the invention is used, the nitrogen concentration of excrement can be reduced by 44%, the phosphorus concentration of the excrement can be reduced by 17%, the copper concentration of the excrement can be reduced by 45%, the zinc concentration of the excrement can be reduced by 34%, and the manganese concentration of the excrement can be reduced by 5%.

Description

technical field [0001] The invention relates to the field of feed, in particular to an ecological and environment-friendly medium-sized pig compound premixed feed for reducing nitrogen, phosphorus, copper and zinc emissions. Background technique [0002] The pig breeding industry generally has the problem of ultra-high emissions of nitrogen, phosphorus, copper, iron, and zinc. The crude protein level in the existing feed formula for pigs is relatively high, but the imbalance of amino acids leads to the ineffective utilization of amino acids, resulting in a large amount of nitrogen being excreted through feces and causing waste and environmental pollution; the biological effects of inorganic copper, iron, and zinc sources In order to pursue the short-term growth of hair color and growth performance, the super-high amount is added, which makes the fecal metal discharge super high and causes environmental pollution; in the past, there was a single addition of balanced amino aci...

The crude protein level in the existing feed formula for pigs is relatively high, but the imbalance of amino acids leads to the ineffective utilization of amino acids, resulting in a large amount of nitrogen being excreted through feces and causing waste and environmental pollution; the biological effects of inorganic copper, iron, and zinc sources In order to pursue the short-term growth of hair color and growth performance, the super-high amount is added, which makes the fecal metal discharge super high and causes environmental pollution; in the past, there was a single addition of balanced amino acids or a single organic trace element source to replace the inorganic trace element source, but There is no precedent for combining the two
