Embodiment 1
[0036] A compound premix for reducing nitrogen pollution in pig farming and a preparation method thereof, the method comprising the following process steps:
[0037] (1) Weigh 2.50kg of L-isoleucine, 2.05kg of L-lysine hydrochloride, 4.82kg of DL-methionine, 1.70kg of L-threonine, 1.80kg of L-valine, DL-color Amino acid 1.84kg and defatted rice bran 8.82kg were put into a small mixer and mixed for 6 minutes;
[0038] (2) Release the mixture, sieve it through a 30-mesh vibrating sieve, put it into a mixer, and mix it for 10 minutes for later use;
[0039] (3) Put 26.47kg of defatted rice bran into the mixer with a hoist, put the pre-mixed amino acid into the large mixer from the feed inlet, and mix evenly for 10 minutes;
[0040] (4) Release the above mixture, weigh and pack.
[0041] When in use, the protein content in the complete feed for piglets is reduced by 1 percentage point, and the compound additive prepared above is added to the complete feed at a ratio of 2.13%, an...

[0045] (2) Release the mixture, sieve it through a 30-mesh vibrating sieve, put it into the mixer, and mix it for 8 minutes for later use;
[0046] (3) Put 26.64kg of secondary powder into the mixer with an elevator, put the pre-mixed amino acid into the large mixer from the feed inlet, and mix evenly for 13 minutes;
[0047] (4) Release the above mixture, weigh and pack.
[0048] When in use, the protein content in the full-price feed for piglets is reduced by 2 percentage points, and the compound additive prepared above is added to the full-price feed at a ratio of 3%, ...
Embodiment 3
[0050] A compound premix for reducing nitrogen pollution in pig farming and a preparation method thereof, the method comprising the following process steps:
[0051] (1) Weigh 1.06kg of L-isoleucine, 0.87kg of L-lysine hydrochloride, 2.05kg of DL-methionine, 0.72kg of L-threonine, 0.77kg of L-valine, DL-color Amino acid 0.78kg and each 5.47kg of defatted rice bran and zeolite powder were put into a small mixer and mixed for 8 minutes;
[0052] (2) Release the mixture, sieve it through a 30-mesh vibrating sieve, put it into a mixer, and mix it for 10 minutes for later use;
[0053] (3) Put 16.40 kg of defatted rice bran and zeolite powder into the mixer with a hoist, put the pre-mixed amino acid into the large mixer from the small material inlet, and mix evenly for 12 minutes;
[0054] (4) Release the above mixture, weigh and pack.
[0055] When in use, reduce the protein content in the full-price feed for piglets by 1 percentage point, add the compound additive prepared abov...
