One. Measure index

Determine the appropriate need of acid of ammonia of animal ration essence and lysine, can have a variety of methods, but the need quantity that all sorts of methods reach is very not consistent. Plan into wait (1997) the amino acerbity composition that through analysing Beijing amino acid comprises the massacre body of red chicken, egg and analyses feather estimation to maintain, use mathematical method, the ideal and amino acerbity pattern of Beijing red chicken was established on the foundation that can digest amino acid. It is with lysine among them 100, acid of ammonia of essence of life is 100. Roth -FX (2001) research 7-28 day chicken of age meat young animal is optimal the ideal and amino acerbity mode when producing property, reach lysine and the optimal scale with acerbity ammonia of essence of life are 100: 108. Corzo (2003) studied cock of age meat young animal is in 42-56 day ration lysine 0.85% when, acid content of different spirit ammonia produces the effect of function to young chicken, the result makes clear: Weightening finish of fryer weight, day and feed are changed rate it is in acid of ration essence ammonia 0.98% when the idealest; Acid of ration essence ammonia is 1.0% when body is heavy the idealest; Acid of ration essence ammonia is 1.05% when chest muscle flesh is the heaviest. This and NRC (1994) commendatory ration essence ammonia is acerbity 1.00% roughly identical. If want to make sure the cutaneous in fryer treatment process is complete,mix reach the action that enhances immunity, acid of ammonia of essence of life is at least in the scale in ration 1.20% . Yin (1995) through butcher the experiment reachs the scale of acid of fit choice ammonia and lysine is ration of young laying hen 1.24: 1. Qureshi (1998) . Proposal, in the to keep good healthy state in high temperature environment, the scale of the Arg in ration and Lys is at least 1.1. Malmlof (1988) think serous urea nitrogen is OK the protein metabolization circumstance inside body of animal of more accurate report and ration the balance circumstance of amino acid, ration when amino acerbity balance is good, chroma of serous urea nitrogen is reduced (Scott, 1982) , reach through the experiment Lys: Arg is 1 ∶ the 1.18 serum urea nitrogen when and acerbity lowest of serum make water, lys: Arg is 1.48 ∶ 1 when for highest, show Lys: Arg is 1.48 ∶ 1 when amino acid is lopsided, and Lys: Arg is 1 ∶ 1.18 when amino acerbity balance is relatively good.

2. Ration composition

Origin of ration energy, albumen, the accretion of amino acid the appropriate proportion that the form can affect lysine and acid of ammonia of essence of life. Balnave (2002) wait with Chen (2003) report, the optimal scale that the egg ammonia acid of active of different live thing should stimulate acid of ammonia of the essence below the condition and lysine to heat is influential. When be being added with the form of hydroxyl analogue when acid of ammonia of the egg in ration, acid of ammonia of essence of life and lysine with 1.35 optimum, when be egg ammonia acid to add a form with acid of DL- egg ammonia, optimal scale 1.05; And Chamruspollert (2002) studied ration is different and methylic the influence that needs a capacity to acid of ammonia of essence of life for body, use acid of DL- egg ammonia and beet respectively alkaline as methylic for body, what think to differ however is methylic the influence that needs a capacity to acid of fryer essence ammonia for body is not remarkable. Ferket. (A research of 1998) makes clear as a result, the acid of ammonia of essence of life that different form adds in ration may be to bring about the account with conflicting effect. Because, amino acid and albumen combine crystal amino acid is being absorbed on existence difference, but Roth-FX (2001) think on the fryer's research, with crystal amino acid replaces protein to do not have apparent effect to producing function and azotic deposit. Veldkamp (2000) also put forward, in tall Arg and Lys scale ration, lysine intake is insufficient, cannot satisfy a fryer to grow need may be the another account with conflicting effect. Zhang (2001) use T fistula to determine the pig is right the research of digestive rate makes clear the apparent of amino acid in pink of 4 kinds of feather, the pig digestive rate to the lysine in feather pink is apparent under acid of ammonia of essence of life. Veldkamp (2000) consider to make clear, ration electrolyte won't affect the appropriate proportion of Arg and Lys evenly.
