maize meal
3.Each group was fed with maize-soybean meal diet consisting of different contents of dEB by adding different contents of CaCl_2 and NaHCO_3 in 7 groups. The dEB contents were assigned to -97 mmol/kg、 3 mmol/kg 、 103 mmol/kg 、 203 mmol/kg 、 303 mmol/kg403 mmol/kg and 503 mmol/kg respectively .
5.(3) Adding SNP to the maize-hydrolyzed blood meal diets, the body weight gain of broiler during 0-21day age was improved 18.9% (P<0.01). The feed conversion efficiency increased 13.8%. However during the whole experimental period (0-42 d), the body weight gain was only improved 3.3% (P>0.05), and feed conversion efficiency increase 1%.
6.At forty-three days of age,broilers(males and females)raised at three different temperatures(8℃,24℃,30～32℃)were force-fed two feedstuffs(maize and soybean meal(SBM))with″TME″method to determine the apparent amino acid availability,the apparent metabolizable energy(AME),apparent metabolizable energy with a nitrogen correction(AMEn) and other indices relative to nitrogen and energy metabolism.
7.The main nutritive composition of 5 mixed food made of different propotions of Peru fish meal, soybean cake, maize and wheat bran, and the growth rate of P. Peticillaus were determined. The results showed that the food mixed with 60% animal source (Peru fish meal) and 35%plant material, accounted for 40-45% of protein, was the best one for the prawn growth.
