| 1 | Effect of variety and drying method on the nutritive value of corn for growing pigs显示文摘Background:This experiment was conducted to determine the nutritive value of corn from the north of China for growing pigs.The experiment examined corn variety(LS1,LS2,LS3 and LS4)grown in one location,drying method(sun dried and artificially dried)and different drying temperatures.Corn harvested at 20-25%moisture was dried to about 12%moisture by sun drying and artificially drying at 80,100,or 120℃ in a fluidized bed dryer.Ninety-six barrows(average BW of 33.4 ± 2.7 kg)were housed in individual metabolism crates to facilitate separate collection of feces and urine.A five-day collection period followed a seven-day diet acclimation period.Results:The results indicated that variety significantly influenced(P<0.01)the 1,000 kernel weight of corn but not the bulk weight.Variety also influenced the available energy content(digestible energy of dry matter,P<0.01;metabolisable energy of dry matter,P<0.01)and digestibility of organic matter(P<0.01),as well as dry matter(P<0.01)and gross energy(GE)content(P<0.02).The drying method of corn significantly influenced the 1,000 kernel weight(P<0.01),bulk weight(P<0.01)and digestibility of ether extract(EE)(P<0.01).No effect of drying temperature on the digestibility of organic matter,dry matter(DM),crude protein(CP),neutral detergent fiber(NDF),acid detergent fiber(ADF)and gross energy was observed,but gelatinization(P<0.05)and test weight(P<0.01)decreased with an increase in temperature.Conclusions:Variety has a significant impact on the nutritive value of corn for growing pigs,and greater attention needs to be paid to these influences in the assignment of the nutritive value of corn given to growing pigs. | Quanfeng Li Meng Shi Chuanxin Shi Dewen Liu Xiangshu Piao Defa Li Changhua Lai | 2014 | Journal of Animal Science and Biotechnology2014，5，4： | 5 |
| 4 | INVESTIGATION OF THE M-INTEGRAL IN CRACK-DAMAGED PIEZOELECTRIC CERAMICS显示文摘M 积分的物理解释在损坏裂缝的压电的问题的分析被调查。在 M 积分和全部的电的热含量(CTEE ) 的变化之间的关系,即, M = 2CTEE,为二维的压电的问题与一个理论推导过程被导出。M 积分可以由于与损坏身体,而非对为常规易碎的固体解释了的全部的势能版本率的描述联系的 pre-existingmicroc-racks 的形成提供对电的热含量版本的更自然的描述,这被显示出。为损坏裂缝的压电的陶艺, M 积分的数字计算被讨论。基于 pseudo-tractionelectric 排水量方法, M = 2CTEE 被数字结果也证明了。 | Wang Defa Ma Lifeng Shi Junping | 2006 | Acta Mechanica Solida Sinica2006，19，2： | 0 |
