Embodiment approach 1

[0023] This is the feed used in the present invention for raising 20-50 kg heavy growing pigs. To produce 100 kg of this feed (unit: kg): brown rice 50.2 corn 20.0 soybean meal 12.0 wheat bran 5.0 fish meal 4 vegetable oil 6.0 salt 0.3 calcium hydrogen phosphate 0.5 sea Paoite 1.0 Premix 1.0 (the premix is ​​mainly composed of copper, zinc, iron, manganese, iodine, selenium, amino acids, and commercially available vitamins, and the proportion of each component to the total amount of the premix is ​​not required. specific circumstances to adjust).

[0024] Proceed as follows during production:

[0025] a, earlier all kinds of raw materials (copper, zinc, iron, manganese, iodine, selenium, amino acid, commercially available vitamins) in the premix are pulverized, cross a 15-20 mesh sieve, and set aside;

[0026] b. Grinding 51.2 kg of brown rice, 20 kg of corn, 12 kg of soybean meal and 5 kg of wheat bran to 6-12 mesh, set aside;

[0027] c, pre-mixing the powder obtained in s...

Embodiment approach 2

[0035] This is the feed used in the present invention to raise 50-100 kg of fattening pigs. To produce 100 kg of this feed, (unit: kg): brown rice 37.2 corn 30.0 meal 20.0 wheat bran 5.0 vegetable oil 5.0 salt 0.3 calcium hydrogen phosphate 0.5 sepiolite 1.0 Premix 1.0

[0036] The production method is the same as the first embodiment.

[0037] The following is the feeding experiment and metabolism experiment done by the inventor with the feed of the present embodiment, and the results are shown in Table 2, which reflects the feed of the present embodiment on the nitrogen balance and production performance of fattening pigs.

Abstract

The present invention discloses an environment-friendly pig feed and a production method. The feed comprises the raw materials in weight percentage that: 25 to 65 of brown rice, 0 to 30 of corn, 12 to 20 of beam pulp, 5 to 13 of wheat bran, 0 to 4 of fish meal, 0.2 to 0.4 of common salt, 0.3 to 1 of dicalcium phosphate, 1 to 3 of sepiolite, 1 to 2 of premix and 0 to 6 of seed fat. The thickness of the SNSP is far lower than 0.8 percent. After the pig eats the feed, the discharge rate of nitrogen is reduced by above 14 percent to 19 percent and the feed conversion rate is increased by 6.7 percent to 14.8 percent, meanwhile, by adoption of the present invention, the lean meat percentage is enhanced, the meal taste is improved and the residue of the medicines such as antibiotic inside the meal is decreased.

Description

technical field [0001] The invention relates to a pig feed and a production method thereof. Background technique [0002] For pigs, non-starch polysaccharides (NSP) in feed have long been considered by academic circles at home and abroad to be anti-nutritional factors and related to microbial fermentation in the gut. The inventor started with the physical and chemical basic structure of carbohydrates, and divided the non-starch polysaccharides (NSP) in the feed into two categories, namely water-soluble non-starch polysaccharides (SNSP) and insoluble non-starch polysaccharides (INSP), and found that the SNSP in the feed , although it does not affect the digestion process of feed nitrogen and amino acid itself (i.e. true digestibility), its content has a linear increasing relationship with pig intestinal microbial fermentation and endogenous nitrogen (amino acid) excretion, thereby reducing the apparent digestion of amino acids However, the INSP content in the feed has no lin...
