Abstract
The invention discloses a pig feed capable of reducing excretion of nitrogen and phosphorus. The pig feed comprises the following raw materials: corn, a degreased tea seed cake without tea saponin, degreased pine needle meal, rice bran, lysine, sulfur-containing amino acid, phytase and a complete pig feed containing trace elements and microorganisms. According to the invention, through usage of lysine and sulfur-containing amino acid, the low-nitrogen content feed meeting requirements for amino acid balance during growth of pigs is prepared, the utilization rate of nitrogen in the feed can be effectively increased, so excretion of nitrogen in pig manure can be reduced; meanwhile, through addition of phytase into the feed, decomposition of phytic acid and phytate in the feed is promoted by phytase to allow endogenous enzymes and other nutrients bonded with phosphorus and phosphate to be released and utilized, so excretion of phosphorus in the pig manure can be reduced; moreover, pine needles and tea meal are used as raw materials, the pine needles are rich in the element zinc, the tea meal which has undergone extraction of tea saponin with ethanol has good palatability, so appetite of the pigs is whetted and growth of the pigs is accelerated.
Description
Technical field
The present invention relates to field, livestock rearing field, be specifically related to a kind of pig feed that reduces nitrogen phosphorus excretion and preparation method thereof.
Background technology
China is the big country of raising pigs, China's live pig amount of delivering for sale in 2010 has reached 7.3 hundred million according to statistics, the fast development of pig industry is to improving people's living standard, promote that rural economic development has played huge impetus, but meanwhile, the foundation on a large amount of extensive pig farms has also brought some corresponding environmental problems.The sewage that produces such as the pig farm directly has influence on its peripheral environment, contain the materials such as a large amount of nitrogen, phosphorus in the pig manure water, a pig year is produced the fecaluria amount about 1500～4000kg, only calculate with a pig farm of producing ten thousand pigs per year, general 108 tons of nitrogen, 31 tons of phosphorus need to be amplified to its perimeter rows every year in this pig farm, these nitrogen phosphorus are deposited on the soil or flow into river and lake through the earth's surface, cause the super nutrient laden of water quality, cause huge pollution.Therefore, be necessary to improve the utilization rate of nutrient in the feed, reduce the excretion of pig farm nitrogen phosphorus, improve environmental quality.
Name is called the following technical scheme in Chinese patent literature record road of " a kind of pig feed " (publication number CN102550866A): a kind of pig feed, described crude protein quality percentage is 13.5%-14.5%, the mass percent of lysine is 0.5% one 1.0%, and the mass percent of sulfur-containing amino acid is 0.1-0.5%; Also comprise phytase, non-starch polysaccharide enzyme, organic trace element additive; Described organic trace element additive comprises amino acid copper, amino acid iron, manganese amino acid, amino-acid zinc, yeast selenium.Although this feed can effectively realize reducing nitrogen content and micro-discharge rate in the ight soil, reduce the effect of environmental pollution, but its palatability to pig is poor, therefore being necessary to provide a kind of can effectively reduce the content of nitrogen and phosphorous in the pig manure, reduce environmental pollution, and the feed of the good palatability of pig.
Summary of the invention
The purpose of this invention is to provide a kind of pig feed that reduces nitrogen phosphorus excretion and preparation method thereof, it can effectively solve the above problems, can effectively reduce the content of nitrogen and phosphorous in the pig manure, reduce environmental pollution, and the feed of the good palatability of pig, can recycle refuse in addition, the cost of producing feed is low.
Concrete scheme provided by the invention is: a kind of pig feed that reduces nitrogen phosphorus excretion, it is made of following weight portion material combination: 40～50 weight portion corns, remove the tea dregs of rice 30～40 weight portions of Tea Saponin, degreasing, degreasing pine needle meal 5～10 weight portions, rice bran 5～10 weight portions, lazy propylhomoserin 0.4～0.8 weight portion, contain methyllanthionine 0.2～0.3 weight portion, salt 0.1～0.3 weight portion, phytase 0.05～0.1 weight portion, the pig that contains trace element, little living bacterium is with complete diet pellet 0.4～0.8 weight portion.
Wherein, pig is raised with full price and refers to energy and corn, remove the tea dregs of rice of Tea Saponin, degreasing, the degreasing pine needle meal, rice bran, lazy propylhomoserin, contain methyllanthionine, salt, the phytase mixed feed of arranging in pairs or groups can satisfy the forage compounding agent of the required various nutritional needs of pig growth fully, and it is rich in required vitamin, the mineral element of pig growth.The tea dregs of rice that remove Tea Saponin, degreasing are to remove the tea dregs of rice behind the Tea Saponin by alcohol steep to place standing for fermentation in the open and obtain after 1～February.
The present invention preferably implements as further prioritization scheme according to following two schemes, has obtained better effect, that is:
Pig feed is made of following component: 40 weight portion corns, remove the tea dregs of rice 40 weight portions of Tea Saponin, degreasing, degreasing pine needle meal 10 weight portions, rice bran 7.75 weight portions, lazy propylhomoserin 0.8 weight portion contains methyllanthionine 0.3 weight portion, salt 0.3 weight portion, phytase 0.05 weight portion, the pig that contains trace element, little living bacterium is with complete diet pellet 0.8 weight portion.
Pig feed is made of following component: 50 weight portion corns, remove the tea dregs of rice 35 weight portions of Tea Saponin, degreasing, degreasing pine needle meal 5 weight portions, rice bran 8.2 weight portions, lazy propylhomoserin 0.4 weight portion contains methyllanthionine 0.2 weight portion, salt 0.3 weight portion, phytase 0.1 weight portion, the pig that contains trace element, little living bacterium is with complete diet pellet 0.8 weight portion.
Pig is 5～15mg/g with copper content in the complete diet pellet, and iron content is 10～15mg/g, and the selenium constituent content is 0.02～0.05mg/g, and lactic acid bacteria content is 10～20mg/g, and the Se-enriched yeast bacterial content is 5～10mg/g.
The production method that reduces the pig feed of nitrogen phosphorus excretion of the present invention, specific as follows:
First with the tea dregs of rice; the degreasing pine needle, corn carries out fragmentation, with the material after the fragmentation and rice bran; lazy propylhomoserin; contain methyllanthionine, salt, phytase; the pig that contains trace element, little living bacterium places drum mixer to carry out the damping mixing with complete diet pellet; deliver to after mixing and carry out granulation in the comminutor, after granulation is finished in drying machine again 140～160 dryings, pack behind dry the end.
Among the present invention by using lazy propylhomoserin, contain methyllanthionine, the feed of the low nitrogen content that meets the required amino acid balance of pig growth of configuration, but the utilization rate of nitrogen in its Effective Raise feed, thus reduce elimination of nitrogen amount in the pig manure.Simultaneously, the present invention is by having added phytase in feed, and the decomposition by phytic acid and phytate in the phytase promotion feed makes other nutrition of the endogenous enzyme of phosphorus and phosphate radical combination be released and utilize, and reduces phosphorus excretion in the pig manure.In addition, use pine needle and the tea dregs of rice as raw material, be rich in the zinc element in the pine needle, adopt the tea dregs of rice animals good palatability behind the alcohol steep Tea Saponin, can promote the appetite of pig, accelerate the growth of pig.
