Zinc oxide is Zincic resource .100mg/kg and 2000mg/kg of zinc oxide is given to the two groups,and the third group is not given.the economic benefits are elevated 11.3% and 26.34% for the foregone two groups.it is obvious that adding zinc into daily diet is better for weaner pigs in growth ,reducing diarrhea rate and elevating economic benefit

试验Ⅰ组和试验Ⅱ组分别添加100mg/kg和2000mg/kg氧化锌，对照组不添加。试验结果表明经济效益分别提高了11.3%和26.34%。可见，日粮中添加锌对断奶仔猪促进生长、降低腹泻率和提高经济效益有明显效果。

In conclusion,lacking for choline and methionine led to decrease growth performance decrease and tibia with short disease; Basal diet supplemented with 750 ppm – 1250 ppm Cholin improved Growth performance ,and prevented the occurrence of perosis. Higher dietary choline can alleviate the adverse effects of methionine and choline deficiency.

总结而论，缺乏胆碱与甲硫胺酸会导致生长性能下降和胫骨粗短症；饲粮中添加750~1250 ppm之胆碱可以改善生长性能及防止胫骨粗短症的发生；饲粮添加高剂量的胆碱，可以缓和甲硫胺酸和胆碱缺乏之不良影响。

Supplemented with 5% coconut milk or 0.2% tryptone in the medium markedly promoted the hypocotyl callus growth, while 0.2% yeast extract had no important effect. Supplemented with 10% coconut milk, 2% tryptone or 2% yeast extract all inhibited the hypocotyl callus growth.

添加5％椰子乳和0.2％胰蛋白胨显著地促进生长，添加0.2％酵母提取液则未表现出显著的促进作用，而10％椰子乳、2％胰蛋白胨和2％酵母提取液均抑制愈伤组织的生长。

The growth of plantlets with the height of 1-2 cm and 3-4 leaves was compared on MS basal medium containing various organic compounds, including banana, carrot, potato, coconut water, and tryptone. The result showed that the growth of oncidium plantlets was the best on medium containing banana, potato and tryptone altogether with respect to their plant height, leave number, root number, root length, fresh weight, and dry weight. The next better media were the control and the Banana medium, followed by the Potato medium.

另外取高约1-2公分，带3-4片叶片的分化小苗，培养於含不同浓度有机添加物（香蕉、胡萝卜、马铃薯、椰子水、及tryptone）的半量MS培养基，以探讨最适合文心兰瓶苗生长的培养基，试验结果显示，在同时含香蕉、马铃薯及tryptone三种成份的培养基生长的小植株不论在株高、叶数、根数、根长、鲜重、及乾重均较其他培养基为佳；不含添加物之1/2MS培养基、及含香蕉的培养基次之，而在含马铃薯之培养基较差。

The results showed that low temperature, high content of salt and acidic condition inhibited ammonifiers growth, and alkalescent condition showed little effect on ammonifiers. Ammonifying bacteria in Suzhou Creek could not use inorganic nitrogen and carbamide as nitrogen source. Additional carbon source have little effect on ammonifiers growth....

结果表明，低温、高盐度和酸性条件会抑制氨化菌的生长；中、碱性条件下，氨化菌仍能维持正常生长；苏州河的氨化菌无法以无机氮和尿素作为生长所需的氮源；在氮源充足条件下添加额外碳源，对氨化菌的生长无抑制作用；苏州河的环境条件有利于氨化菌的生长。

In conclusion, the growth performance and antioxidant capacity of laying duckings could be improved by adding 10 mg/kg VB2 to the diet. However, both a too and a too low level of vitamin B2 could affect the performance and antioxidant capacity of laying ducklings in cage.

由此得出，日粮添加10 mg/kg VB2能显著增强蛋雏鸭的生长性能和抗氧化能力，VB2添加过高过低都会阻碍抗氧化和促进生长能力的发挥。
