Embodiment

[0021] 1. Germination of wheat

[0022] The wheat harvested in the current year is selected to ensure a high germination rate. Take 200kg of wheat, soak it in clear water overnight, put it in the bean sprout machine, start the germination automatic control program, germinate for 1-2 days, and take it out when the length of the wheat sprouts is between 0.3-0.5.

[0023] 2. Feed processing method

[0024] 1. 479kg of corn, 50kg of sprayed corn husks, 160kg of soybean meal, 93kg of wheat bran, 2kg of lysine, 10kg of stone powder, 3kg of salt, and 3kg of premix are processed according to conventional feed processing methods, totaling 800kg.

[0025] 2. After the germinated wheat is crushed, mix it into the above-mentioned feed, and at the same time add an appropriate amount of water (approximately 1:1 water) to form a full-price wet mix.

[0026] 3. Feeding method

[0027] Feed the full-price wet mix directly to the fattening pigs, feed freely, and adopt a small amount of feedi...

Abstract

The invention relates to a method for feeding sprouted wheat to reduce phosphorus environmental emission of manure produced by raising pigs and belongs to the technical field of ecological breeding. According to the method, a principle that the high phytase activity is generated in a wheat seed sprouting primary period and natural phytate phosphorus in a feed is catalyzed into effective phosphorus capable of being used by the pigs is utilized; the content of the phosphorus in the pig manure is reduced under the precondition that the growth speed of the pigs is not influenced and calcium hydrogen phosphate is not added in pig feed, and the emission amount of the phosphorus in the pig manure to the environment is reduced. The method has the technical essentials that the sprouting length of wheat is controlled to be 0.3-0.5 centimeter; the feeding amount accounts for 20% of the mass of pig complete feed dry materials; exogenous phosphorite including the calcium hydrogen phosphate and the like is not added to the pig feed, the growth speed of the pigs is not lowered and the content of the phosphorus in the pig manure is reduced by 45%.

Description

1. Technical field [0001] The patent of the invention relates to the technical field of agricultural ecology, especially in the aspect of ecological breeding, a feeding method for reducing environmental pollution caused by manure phosphorus in large-scale pig farms by adopting ration nutrition control technology. 2. Background technology [0002] Fecal environmental pollution has always been an important factor restricting the development of the pig industry. On the other hand, pig manure is also one of the important sources of farmland organic fertilizer. The use of livestock manure organic fertilizer instead of chemical fertilizer in farmland is the core measure of modern planting and breeding combined with circular production mode, which not only saves planting costs, protects soil ecology, but also improves the quality of agricultural products. Usually, the amount of organic fertilizer is determined by the demand of crops for nitrogen. For most crops, the appropriate abs...
