Description
Technical field
The present invention relates to a kind of feed and using method thereof, relate in particular to a kind of low protein ration premix compound for the pig that grows and using method thereof.
Background technology
China is pig-breeding and consumption big country, and within 2012, Chinese live pig livestock on hand is 47,492 ten thousand, and live pig is delivered 69,628 ten thousand for sale, 5,335 ten thousand tons of pork output, within 2012, feed industry output reaches 1.94 hundred million tons, is 1.8 times in 2005, and the Feed Manufacturing total size has occupied first, the whole world; The up-to-standard rate 95.7% of feed product, improved 3.3 percentage points than 2005; Produce Feed Enterprise or the enterprise group family more than 30 more than 500,000 tons per year.
The fast development of animal husbandry, for society provides the protein foods such as abundant meat, egg, milk, is significantly improved people's living standard.But the development of herding industry has also brought problem in many ways to people.At first be to cause environmental pollution.According to measuring and calculating, in pig industry, every pig is on average produced 2.5 tons of fecalurias per year, just 30,000 tons of ten thousand pig farm environment defecation at least towards periphery every year on average, and 100～150 tons of every daily blowdown water amounts, and the ight soil odor pollutant is up to kind more than 200.Secondly, the fast development of animal husbandry causes feed resource critical shortage, particularly protein feed resource, and the protein feeds raw material of China's feedstuff industry more than 70% need to be from external import.According to statistics, 2011 Chinese soybean output are less than 2,000 ten thousand tons, and soybean import is 5,600 ten thousand tons.For this reason, be to ensure continuing, developing in a healthy way of feed industry, animal husbandry, need the feeding manner of a kind of more efficient, saving and environmental protection.
The generation that progressively deep and synthesizing amino acid is produced along with animal nutrition research, making take " ideal amino acid " pattern is that the low-protein diet that prepare on basis becomes possibility, daily ration is prepared by " thick protein " to " total amino acid-can digest amino acid-ideal protein pattern " transition, under the prerequisite that does not affect livestock and poultry production performance, use the synthetic amino acid (lysine of industry, methionine, tryptophan, threonine etc.) regulate the amino acid balance in low crude protein content daily ration, excessive and the waste that causes of the safety margins of avoiding Dietary Crude Protein, not only save protein resource but also reduced the excretion of nitrogen.Increasing research shows: by the daily ration of desirable protein pattern preparation, its thick protein level reduces by 2～4 percentage points, does not affect the normal production performance of livestock and poultry, and simultaneously, the nitrogen discharge rate can reduce 20%～50%.
The internal feed resource lacks relatively at present, and particularly the scarcity of the protein feeds such as dregs of beans, fish meal, seriously restricting the development of animal husbandry.Threonine is the second or the 3rd limiting amino acid in pig feed normally, it is the 3rd or the 4th limiting amino acid of poultry feed, along with lysine, the extensive use of methionine composite in mixed feed, it becomes gradually affects the major limitation of livestock and poultry production performance sexual factor, especially in low-protein diet.The production method of threonine mainly contains fermentation method, three kinds of proteolysis method and chemical synthesis, and microbe fermentation method has become the main stream approach of producing threonine at present.It is that to take the less wheat of threonine content be feed that most of Europe is raised family, recent years particularly, along with the rapid growth of the areas such as Asia, North America to the threonine demand, the demand sustained, stable growth of international market to threonine, be one of amino acid kind that demand growth is the fastest.At present, it is mainly Jilin great achievement etc. that Chinese threonine is supplied producer, and abroad threonine supplier is mainly aginomoto, Degussa and Japan's consonance and U.S. ADM company etc.
At present, the commercialization low-protein diet of report is more and more, Lv Mingbin (2007) has invented " a kind of preparation technique of low-protein diet for fattening pig ", Chen Gang (2007) periodical has proposed " sucking pig low-protein daily food and using method thereof ", " planting the formula of the low egg of in-pig from daily ration " reported in Lie group road (2007), Xu Jianguo (2009) has been invented " a kind of low protein ration premix compound for the pig that grows and using method thereof ", Zhu Yuanzhao (2010) has invented " 4% low-protein daily ration piglet premix ", Jiang Xuming (2011) has invented " a kind of low-protein amino acid balance agent of feed for nursing sow ".But, from feedstuff, above invention is the low-protein diet feed that need to add lysine, threonine and methionine, under threonine high price or environment in short supply, must cause the limitation of its use.
Summary of the invention
The technical problem to be solved in the present invention is to provide ration premix compound and the using method thereof that a kind of growth pig that does not need to add threonine is used.
