Problems solved by technology

Under actual production conditions, there are many unfavorable factors, such as aflatoxin in feed, lipid peroxide, nutritional imbalance, etc., and various stress reactions (such as heat stress, oxidative stress, disease infection, etc.), All will lead to intestinal dysfunction and attenuation, increase carbon and nitrogen emissions, and hinder the development of low-carbon pig breeding

preparation example Construction

[0019] The preparation method of the pig feed additive with low carbon and nitrogen emissions is as follows: both the fumaric acid and the hydrotalcite are ground to more than 200 meshes, and then the two are evenly mixed, and then evenly mixed with the fiber oligosaccharide and the montmorillonite zinc oxide compound.

[0020] Alternatively, both the fumaric acid and the hydrotalcite are ground to a size greater than 200 meshes, and then the two are evenly mixed, and then evenly mixed with the cellooligosaccharide and the zeolite zinc oxide compound.

[0021] The present invention is further illustrated in conjunction with the following examples.

[0023] Preparation: according to the literature "Preparation of zinc oxide–montmorillonite hybrids" (see: Khaorapapong, N., N. Khumchoo, M. Ogawa. Mater. Lett. 2011, 65:657–660) to prepare montmorillonite zinc oxide composites thing. In terms of weight percentage, the content of zinc oxide in the montmorillonite zinc oxide composite is 10%.

[0024] 50 kg of fumaric acid and 50 kg of hydrotalcite are both ground to a size larger than 200 meshes, then the two are mixed evenly, and the mixture is mixed with 100 kg of cellooligosaccharides and 100 kg of montmorillonite zinc oxide complex, and then mixed thoroughly to obtain a pig Use feed additives with low carbon and nitrogen emissions (Feed additive to reduce C and N emission, FA-RCNE). The dosage in pig feed is 0.1~0.5%.

[0027] Preparation: Prepare montmorillonite according to the method in the literature "ZnO / montmorillonite for photocatalytic and photochemical degradation of methylene blue" (see: Fatimah, I, Wang, SB, Wulandari, D. Appl. Clay Sci. 2011, 53, 553-560.) Delithified Zinc Oxide Complex. The content of zinc oxide in the montmorillonite zinc oxide composite is 5% by weight percentage.

[0028] 200 kg of fumaric acid and 200 kg of hydrotalcite are ground to a size larger than 200 meshes, then the two are mixed evenly, and the mixture is mixed with 500 kg of cellooligosaccharides and 1,000 kg of montmorillonite zinc oxide compound and then mixed thoroughly to obtain a pig Use feed additives with low carbon and nitrogen emissions (Feed additive to reduce C and N emission, FA-RCNE). The dosage in pig feed is 0.1~0.5%.

Abstract

The invention discloses a pig feed additive with low emissions of carbon and nitrogen. The pig feed additive comprises the following components in parts by weight: 0.5-2 parts of fumaric acid, 0.5-2 parts of hydrotalcite, 1-5 parts of cello-oligosaccharide, 1-10 parts of a montmorillonite zinc oxide compound; or the pig feed additive comprises the following components in parts by weight: 0.5-2 parts of fumaric acid, 0.5-2 parts of hydrotalcite, 1-5 parts of cello-oligosaccharide, 1-10 parts of a zeolite zinc oxide compound. Through the pig feed additive with low emissions of carbon and nitrogen, the function of the fumaric acid of reducing methane yield, the function of the cello-oligosaccharide of adjusting intestinal microecology, the function of the montmorillonite / zeolite zinc oxide compound of protecting intestinal mucosa, inhibiting urease and absorbing nitrogen and the effect of the hydrotalcite of slowly releasing a carrier are combined organically to generate a synergistic combination effect, so that the nitrogen emission in the pigsty can be reduced by 30-70%, the ammonia emission in the pigsty can be reduced by 30-50% and the methane emission can be reduced by 20-30%.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive with low carbon and nitrogen emissions for pigs. Background technique [0002] Global warming is mainly caused by the greenhouse effect caused by the high concentration of greenhouse gases in the atmosphere. Atmospheric carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) are three important greenhouse gases. It is estimated that greenhouse gases directly or indirectly produced by the global livestock industry account for 18% or more of the total annual emissions (FAO, 2006). my country has developed into the world's largest pork production and consumption country. According to the FAO (2006) report, my country is the world's largest methane emitter from animal manure, accounting for 22% of the world's total, and more than 80% of which comes from pig manure. CH 4 As one of the important greenhouse gases, its warming potential is about 2 23 times that of ...
