NUTRISI OF PRAWN WINDU (Penaeus Monodon) . PROTEIN AND ACID of AMINO ESENSIAL

CONDITIONS OF NUTRISI TO PRAWN of WINDU.

Source of nutrisi ( gizi) [is] generally classified to become five category, that is: protein, fat, carbohydrate, mineral and vitamin. To support growth and continuity of its life, prawn require nutrisi which qualitative and also quantitative fulfill conditions as according to requirement of prawn. the Iihat vitamins have to stay in food which physiologically function as source of regulator Iihat vitamin of[is continuity of life.

PROTEIN AND ACID of AMINO ESENSIAL.
Protein represent organic compound [of] complex, lapped over to the many acid of amino pregnant [of] elements of C, H, O and of N which [do] not have by carbohydrate or fat. pregnant Protein molecule also sulphur and phospor. Protein of vital importance to body, because this Iihat vitamin have function as materialss in body and also as constructor Iihat vitamin and regulator. As constructor Iihat vitamin, functioning protein in forming new network and maintain network which have there [is].


Considering is important [of] protein in prawn food, hence research concerning requirement of protein some prawn type have been [done/conducted] by many researcher. Some result of research show number requirement of different protein to prawn. Difference [is] enabled, caused by difference in habit eat ( habit food) as well as source of used protein. Pursuant to attempt of Deshimaru and of Yone ( 1978) got that optimum protein rate for the growth of Penaeus japonicus juvenil and efficiency usage of food range from 32 - 57 %.


While other researcher like Colvin ( 1976) getting protein rate 43 % for the Penaeus of and indicus of Andrews al et. ( 1972) getting protein rate 28 - 32 % for the Penaeus of setiferus. Result of attempt of Colvin and of Brand ( 1977) indicating that for the growth of prawn of Penaeus califomiensis, Stylirostris Penaeus and of Penaeus size measure vanamei of pasca larva required [by] 40 % protein in its food, while for juvenil required [by] protein 30 %. In general prawn of windu adult or juvenil get optimum growth with [gift/ giving] of pregnant food 30 - 60 % protein ( New, 1976).


[In] nature there are [about/around] 23 kinds of acid of amino which have insulation, but only some just acid of amino which [is] esensial to prawn. Kanazawa and of Teshima ( 1981) by using radioactive isotope get 10 sour type [of] esensial amino for the Penaeus of japonicus that is : Arginin, Methionin, Valine, Threonin, Isoleusin, Leusin, Lysin, Histidin, Phenylalanin and of Tryptophan. While Shewbart etal. ( 1972) getting 11 acid of amino esensial to Penaeus aztecus that is kesepuluhjenis above additional and also Tyrosin for a few high level animal. This Tyrosin [do] not esensial if/when there are Phenylalanin, however seems esensial to prawn. Till now requirement of acid of amino quantitatively to prawn not yet been known. Any way compilation of prawn food better be adapted for [by] spreading of acid of amino in prawn body.

[At] tables 2 seen component spreading of acid of amino prawn of windu.
