| 1 | Virulence of Newcastle disease virus is determined by the cleavage site of the fusion protein and by both the stem region and globular head of the haemagglutinin -neuraminidase protein显示文摘 | de Leeuw O S Koch Guus Hartog Leo | 2005 | J Ge Virol2005，86，6： | 1 |
| 2 | 提高动物生产效率 保障食品优质安全显示文摘随着世界人口激增、城市化进程的加剧以及中产阶级的日益壮大,全球动物营养产品的需求量不断攀升。预计到2050年全球人13达到90亿时.人均肉的消费量为50kg,奶制品的消费量为99kg。相对于目前的消费水平,肉类和奶制品的需求分别增加了75%和53%。 | Leo den Hartog | 2013 | 中国猪业2013，8，11： | 0 |
| 3 | Supplementing oat hulls to the diet of suckling piglets altered their intestinal tract and colonic microbiota development显示文摘Current study evaluated the effect of a fine and coarsely ground insoluble dietary fibre source on the gastrointestinal development of suckling pigs.Oat hulls(OH)were selected as a model feedstuff,rich in cellulose,lignin,and insoluble dietary fibre.Three experimental supplemental diets were formulated:a finely ground,low fibre and nutrient dense diet served as control(CON).For the 2 high fibre diets,15%heat-treated starch in CON was exchanged with OH,either finely(OH-f)or coarsely ground(OH-c).Litters of 10 primi-and multiparous sows(mean litter size 14.6±0.84)were used.Within a litter,experimental diets were allotted to triplets of 4 piglets.From approximately 12 d of age,piglets’individual feed intakes were recorded 2 times per day when separated from their dam for 70 min.Piglets could suckle with their dam for the remainder of the day.On d 24 and 25,from the total pool of 120 piglets,seven healthy well-eating piglets per treatment were selected for post-mortem evaluation,resulting in 14 replicates per treatment.Consumption of OH-c and OH-f did not impede clinical health and production performance of piglets.The full stomach weights tended to be greater for OH-c compared to OH-f whereas CON was intermediate(P=0.083).Supplementing OH significantly increased ileal villus height and caecal dry matter concentration(P<0.05).For the colon,OH increased its length,contents weight,short-chain fatty acid concentration and reduced total bacterial count as well asγ-proteobacteria count and proportion(P<0.05).The OH-c treatment specifically increased full gastrointestinal tract weight and caecum contents weight compared to piglets fed CON and OH-f.Furthermore,OH-c reduced colonic crypt depth when compared to OH-f(P=0.018).In conclusion,supplementing OH to a diet for suckling piglets exerted subtle developmental effects on gastrointestinal morphology and colonic microbial community.These effects were largely independent from the particle size of the OH. | Hubèrt M.J.van Hees Koen Chiers Leo A.den Hartog Theo A.T.G.van Kempen Dominiek Maes Sam Millet Geert P.J.Janssens | 2023 | Animal Nutrition2023，，1： | 0 |
| 4 | 西欧研发现状显示文摘本届年会组委会邀请了荷兰泰高集团研发中心主席Leo den Hartog先生介绍了西欧的研发情况,分析了世界上主要科技发达国家科研状况,对欧洲、美洲、亚洲等地区的科技创新工作进行了展望。文中特别预测中国的科研实力将是世界增长最快的国家。同时,在欧盟还有一些科研合作基金可供争取。文中的观点值得我国科技工作者思考。 | Leo den Hartog | 2006 | 中国家禽2006，28，21： | 0 |
| 5 | 繁殖母猪的日粮供给量显示文摘现在,可根据广泛的研究结果,决择最佳母猪繁殖力的饲养管理。当然,母猪在任娠期间所需的饲料能,除了维持生命的物理活动外,还用于自身生长和胎儿发育。上述每项需要都可以准确地计算出来。首先根据母猪体重的1%进行估算,计算维持需要一头体重170千克的母猪每天需要1.7千克的正常母猪饲粮,即每千克饲粮含有12.6兆焦代谢能。在整个妊娠期间,如果该母猪母体增重增加25千克,则需要在维持需要的基础上每天补给1千克饲料。如果平均每天再供给100克饲料,用于胎儿生长发育,那么该母猪在整个妊娠期间平均每天共计应得到2.8千克饲料。 | 程伟 Leo den Hartog | 1993 | 国外畜牧学(饲料)1993，，4： | 0 |
