blood meal
6.Amounts of Certain elements in Anopheles sinensis, both normal ones (emerged mosquitoes, d0, d5, d8, d12 and d18 after taking blood meal) and those infected with Brugla malayi microfilaria (d5, d 8, d12 and d18 after infection), were determined using IL-551 and PE-603 atomic absorption spectrometer(AAS).
7.77% of the stained specimens from first to eleventh successive day could show the growth lines in the laboratory-reared mosquitoesThis technique was used to study the calendar age of Anopheles sinensis caught outdoors in October 1981. It was found that the calendar age from first to fourth blood meal was 1.4 days, 4.7 days, 7.4 days and 10.2 days respectively.
8.(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%.
