为探究滇西北高海拔地区提高牦牛养殖补饲水平、促进产业结构调整、实现高原特色畜牧业绿色健康发展的草地建植模式。在迪庆藏族自治州香格里拉市小中甸县开展了小黑麦(×Triticosecale Wittmack,T)和饲用豌豆(Pisum Sativum,F)混播试验,对不同处理下的饲草产量、品质和土壤养分等进行评价。结果表明:饲用豌豆与小黑麦适当混播在一定程度上可增加饲用豌豆的株高,有利于田间收获;适宜混播可有效提高饲草产量,混播比例T∶F为40∶60可获得较高的饲草产量,与小黑麦单播相比,干草产量增加59%,鲜草产量增加113.1%;与饲用豌豆单播相比,干草产量增加18.9%,鲜草产量增加10.1%;该比例下的粗蛋白含量为18.5%;较小黑麦单播处理,小黑麦与饲用豌豆适宜混播可改善土壤速效磷和速效钾含量。综合考虑饲草产量、品质和表层土壤性状,得出小黑麦与饲用豌豆混播最佳比例是40∶60。

世界核心医学期刊文摘（皮肤病学分册） 2006年第6期2卷 31-31页

作者： Landgren e. Brbck L. Hedlin G. F. Rasmussen 罗素菊 Health epidemiology Group Department of Public Health Sciences Karolinska Institutet SE-171 76 Stockholm Sweden

Background: According to the T-helper (Th)1/Th2 paradigm, it has been argued that Th1-dominated diseases such as psoriasis and Th2-dominated diseases such as asthma and hay fever should be mutually exclusive, as the immune regulatory cells, Th1 and Th2, cross-regulate each other. An increase in asthma and hay fever has occurred in Sweden over the past four to five decades, but the time trend for psoriasis is not clear. Objectives: To assess the prevalence of psoriasis in young Swedish men over a period of three decades and the association between psoriasis and allergic disorders. Methods: Register study based on data from the Swedish Military Service Conscription Register and the Total Population and the Population and Housing Censuses. Psoriasis, asthma (with and without allergic rhinitis) and allergic rhinitis at conscription were studied in 1 226 193 male conscripts in successive cohorts born between 1952 and 1977. Results: The prevalence of psoriasis was about 0.5%and it remained stable over three decades. Conscripts with psoriasis and their siblings were less likely to have eczema. The reduced risk of eczema in conscripts with psoriasis was unchanged over time. A reduced risk of allergic rhinitis was also demonstrated in conscripts with psoriasis and their siblings but only in the most recent birth cohort born between 1970 and 1977. Conclusions: A strong genetic influence may explain the unchanged prevalence of psoriasis in Swedish conscripts. Agenetic predisposition for psoriasis may confer partial protection from eczema and allergic rhinitis. The inverse relationship between allergic rhinitis and psoriasis appeared to be a recent phenomenon.

为了研究微贮稻草饲料的制备及其对奶牛产奶量和奶品质的影响,为贵州乳业发展和饲料资源开发提供理论依据和参考数据,试验选用干稻草切碎至3 cm左右,添加微生态制剂密封厌氧发酵,通过微生物的发酵作用制成稻草微贮饲料.选取16头泌乳期奶牛,随机分为2组,每组8头,试验组日粮中添加微贮稻草10 kg,对照组日粮中添加不发酵的稻草秸秆10 kg,每天分早、晚2次饲喂,预饲期15 d,正试期30 d,记录产奶量并采集牛奶样品进行奶品质检测.结果:与对照组相比,饲喂微贮稻草的试验组日均产奶量增加1.46 kg,提高6.9%(P<0.05);乳蛋白含量提高7%(P<0.05),乳糖含量提高6.8%(P<0.05),乳脂率无显著变化.
