Embodiment 1

[0028] Formula one: every 1000 kilograms of the pig feed of the present invention contains: 740Kg of corn, 150Kg of soybean meal, 60Kg of bran, 10Kg of zeolite powder, wherein the mass percentage of crude protein is 13.8%, 5Kg of lysine, 1Kg of sulfur-containing amino acid, the pig feed The amount of phytase added is 100g, the amount of non-starch polysaccharide enzyme added is 200g, and the addition of organic trace elements is made of amino acid copper: 20g of copper, amino acid iron: 60g of iron, amino acid manganese: manganese The content is 10g, amino acid zinc: the content of zinc element is 60g, yeast selenium: the content of selenium element is 0.15g, and the content of iodine element in calcium iodate is 0.2g.

[0029] Formula two: every 1000 kilograms of the pig feed of the present invention contains: 735Kg of corn, 155Kg of soybean meal, 60Kg of bran, and 10Kg of stone powder, wherein the crude protein mass percentage is 14.1%, and the mass percentage is 2% of 4% pre...

Embodiment 2

[0033] Influence of the compound feed of the present invention on pig growth performance.

[0034] Experiments were carried out at the pig breeding base of Youlico Agriculture and Animal Husbandry Development Co., Ltd., Putian City, Fujian Province, to verify the beneficial effect of the pig feed of the present invention.

[0035] 1. Low-protein diet formula and application effect

[0036]Select 300 "Du Changda" three-way hybrid growth pigs with a body weight of about 35 kg as the research objects, and divide them into a control group and 4 experimental groups according to the principle of similar body weight and the same sex ratio, with 3 pigs in each group Repeat, 20 pigs per replicate, the experiment was terminated when the pigs reached a body weight of approximately 60 kg. The control group was fed a high-protein diet with a crude protein content of 16.8%, and the four test groups were fed with a crude protein content of 15.8%, 14.8%, 13.8%, and 12.8%. According to the di...

Abstract

The invention aims at clearing best combination of low protein daily ration, phytase, compound enzyme preparations and develops safe, efficiency and environmentally-friendly pig feed. The technical scheme of the big feed is that the weight percentage of crude protein is 13.5% to 14.5%, the weight percentage of lysine is 0.5% to 1.0%, the weight percentage of sulphur amino acid is 0.1% to 0.5%, and the pig feed further comprises phytase, non-starch polysaccharase, organic microelement additives including copper amino acid, ferro amino acid, manganese amino acid, zinc amino acid and yeast selenium. The low-protein low-phosphorous daily-ration pig feed using low addition amount of the organic microelement additives can remarkably reduce nitrogen content in excrement and discharge amount of microelements, thereby effectively reducing environment pollution.

Description

technical field [0001] The invention belongs to the field of pig raising in animal husbandry, in particular to an environment-friendly feed for pigs. Background technique [0002] At present, the pig industry has developed rapidly and has become an important part of my country's animal husbandry. The problem of environmental pollution caused by pig farming is becoming more and more serious. Energy conservation and emission reduction, and the development of environmentally friendly pig feed are important measures to achieve sustainable development of the pig industry. Pigs excrete a large amount of undigested and absorbed nutrients such as nitrogen and phosphorus through feces and urine every day. On average, each fattening pig produces 4.55 liters of feces per day, which means that each fattening pig excretes an average of 9.5 kg of nitrogen and about 6.8 kg of phosphorus per year. Therefore, it is of great significance to balance the nutritional needs, improve the feed ut...
