    In general .milk replacers are classified as “all-milk” of “alternative” protein milk replacers. All-milk-protein milk replacers should contain only milk ingredients such as WPC, dried whey, dried whey product(delactosed whey), dried skim milk, casein, or sodium (or calcium) caseinate. Alternative protein milk replacers will contain some portion of the nonmilk protein sources discussed earlier in this chapter and , as a result , are less expensive. A typical industry practice in formulation of alternative protein milk replacers is to
    
replace 50% of the milk protein with lower-cost nonmilk proteins. Recommendations about the acceptability of common protein sources are given in Table 2.

a: Industry notation indicated the percentages of crude protein and crude gat on an ai   r-dry basis 
    
b: Formulation also would be similar for use of modified wheat protein rather than soy  isolate.
    
C: Formulation    also would be similar for use of porcine or bovine plasma protein rat   he  r than soy protein concentrate.

其實呢,專業英語并不難,只要有一定專業基礎,加上對專業英語詞匯熟悉,看懂專業英文資料并不費勁,但是費時啊,呵呵......
