Abstract


The test on the basis of the three stages of growing and finishing pigs fattening law to explore the feasibility of a four-stage finishing in growing and finishing pigs . Introduction of the ideal protein amino acid balance mode , respectively, in the three-stage finishing law and four - stage finishing law to use a low-protein diets supplemented with essential amino acids such as lysine and methionine , and explore a different mode of feeding for pigs in various stages of production . performance , nutrient digestibility , blood urea nitrogen and total protein content and carcass composition . On this basis , the economic benefits of different feeding pattern assessment , in order to seek a new , more reasonable growth in finishing pigs feeding pattern . The test results show that ( 1 ) in the three-stage and four - stage finishing law in pig growth stages were low in protein , essential amino acids supplemented diets available and similar to the production of high-protein diets performance . Can improve the digestibility of crude protein and lower blood urea nitrogen content , improve economic efficiency , and carcass composition . ( 2 ) three-stage finishing method with four stages of fattening law , regardless of the use of low-protein diets supplemented with essential amino acids , or the use of high-protein diets , from the overall production performance and economic point of view , the four stages of fattening method help to improve the performance of pig production , reduce feed costs , improve economic efficiency .
