| 1 | 高产奶量的母猪有更高的采食量和体动员显示文摘选择能哺育更大窝产仔数的超高产母猪以提高产仔数,但是综合考虑这些现代母猪产奶量、采食量和体动员相互之间联系的研究还很有限。试验旨在研究什么样的母猪产奶量高、窝产仔数多,不同胎次有何影响,以及哺乳期生产性能对下一胎繁殖性能有何影响。选择565头1~4胎母猪,试验期从产前7 d至断奶。产后第2天每窝仔猪统一调整为14头。产前7 d、产后第2天和断奶时测定母猪体重和背膘厚度。产后第2天和断奶时称取仔猪窝重。计算变量之间的皮尔森相关系数,建立回归模型。母猪的平均日采食量(6.1±1.1)kg,仔猪每天窝增重(2.92±0.53)kg,每头母猪的平均断奶仔猪数(13.0±1.1)头。总的来讲,与2~4胎母猪相比,1胎母猪平均日采食量和产奶量更低,下一胎总产仔数也下降,这可能是因为初产母猪相比经产母猪会动用更多体储。仔猪每窝平均日增重与母猪的采食量、窝产仔数和体重损失呈正相关。1~4胎母猪整个哺乳期日采食量每提高1 kg,仔猪窝日增重提高220~440 g,母猪哺乳期体重下降6.6~13.9 kg。但是每天平均产奶量提高1 kg,第4胎母猪哺乳期体重损失减少4.3~21.0 kg。下一胎总产仔数与上一胎产仔数呈正相关。总之,高采食量和高体动员是高产奶量的先决条件。母猪可能已经非常接近他们身体饲料摄取的生理极限,因此,未来的研究应着眼于优化哺乳期超高产母猪的饲粮能量和营养浓度以及初产母猪和经产母猪之间的区别。 | Strathe A V Bruun T S Hansen C F 李元凤 | 2017 | 养猪2017，，4： | 8 |

| 3 | 西双版纳傣族及上海汉族群体HLA-DR2相关的DR/DQ单倍型分析显示文摘对44名西双版纳傣族和9名上海地区汉族DK2阳性个体进行了与其相关的DR/DQ单倍型组合的分析。傣族群体中DRBI-DR2亚型分布以*1602与*1502为最常见,其等位基因频率分别为43.6%与,40.0%和汉族群体中以*1501为主明显不同。傣族群体中共检出10种与DR2相关联的DR/DQ单倍型;最常见的是DRB1*1602、DRB5*0101、DQA1*0102、DQB1*0502(34.5%)与汉族及其他群体明显不同,本研究表明傣族不仅具有高频率的DR2,而且与DR2相关联的DRB1、DRB5、DQA1、DQB1单倍型组合有其独特性。 | 范丽安 杨珏琴 姚芳娟 董建中 许玲娣 陈仁彪 M Sirkong R Vongrathna P Longta S Lekmak D Chandanayingyong A Smith J Hansen | 1995 | 中华医学遗传学杂志1995，12，3： | 2 |
