大豆种衣剂有效成分配比优选及应用研究I大豆种衣剂有效成分的选择及应用

植物生长调节剂Cc使大豆株高降低，根系活力增强，总根长增加，地下部干重增中18.41%～35.13%，差异显著，地上部干重增加6.58%～15.79%；多元络合态微肥Mi使大豆株高增加叶面积增大，地上、地下部干重分别增加8.5%～13.16%、11.31%～15.30%，差异均显著，杀虫杀菌剂Ki使大豆病株降低20～21.5个百分点，低浓度的Ki使大豆出苗率增加，根系活力增加，地上、地下部干重分别增加3.95%～14.47%、5.32%～14.41%，高浓度的Cc、Ki对大豆出苗不利。

柴达木盆地家畜育肥饲草料营养成份分析

对柴达木盆地地产育肥饲草料进行了营养成份分析，结果表明，柴达木盆地地产饲草料育肥家畜的日粮配方，与省内其他地区育肥家畜日粮配方的营养水平基本相当，只是磷含量较少，应适当增加磷比例。     

Use of Porcine Meal in Plant‐based Practical Diets for Pacific White Shrimp,Litopenaeus vannamei

Two growth trials were conducted to evaluate and confirm the efficacy of a porcine meal (PM) with high protein content (>90%) as an alternative feed ingredient in commercial‐type feed formulation for Pacific white shrimp, Litopenaeus vannamei. Six experimental diets were formulated for the two growth trials. The first five diets contained increasing levels (0, 1, 2, 4, and 6%) of PM as a replacement for soybean meal in a plant‐based diet with low inclusion level (6%) of fish meal (FM). The last experimental diet was produced utilizing 4.2% PM to completely replace FM. In Trial 1, shrimp (1.5 g initial mean weight, 20 shrimp/tank, n = 4) were offered test diets for 6 wk in a semirecirculation system. At the end of Trial 1, shrimp fed with the diet containing 6% PM exhibited significantly enhanced weight gain (WG), feed conversion ratio (FCR), and survival compared to those fed with the diet devoid of FM. As survival was poor across all treatments and different densities could mask growth results the trial was repeated. In Trial 2, shrimp (0.85 g, 15 shrimp/tank, n = 4) were offered diets for 6 wk. Dietary supplementation of PM at 6% significantly improved WG, FCR, and apparent net protein retention in contrast with the treatment devoid of FM, confirming the same trends in Trial 1. No significant difference was detected in protein, lipid, moisture, and mineral profiles of whole‐body shrimp as well as survival across all the treatments. Results of this study indicate that PM is a good high protein source in shrimp feeds, which can be included up to 6% in the low FM‐based diet without compromising the growth of shrimp.     

果蔬籽油生物活性研究进展
