Twenty one-year-old local male dogs were randomly assigned into four groups (five dogs per group).The control and the ethylene glycol (EG) groups were fed basal diets without and with EG, and the EG+sodium selenite (EG+SS) and EG+selenium yeast (EG+SY) groups were fed basal diets with EG containing SS and SY,respectively.Blood, urine and renal samples were taken after 18 weeks of feeding.The results showed that compared with the control group, the serum calcium levels and antioxidase activities significantly decreased in the EG group.Serum creatinine, urea nitrogen and malondialdehyde (MDA) levels and urine calcium and oxalate levels significantly increased.Calcium oxalate crystal deposition and osteopontin (OPN) mRNA and protein expression in the renal tissues significantly increased.These changes above in the EG group were reversed within limits by adding selenium in the diets (both EG+SS and EG+SY groups).Further, compared with the EG+SS group, the EG+SY group showed better effects in decreasing the formation of EG-induced calcium oxalate renal calculi and OPN expression and improving antioxidant capability in dogs.It indicates that organic selenium has the potential value to alleviate the formation of EG-induced calcium oxalate renal calculi.

为了确定一步恒温检测试剂盒是否适用于牛支原体,将实验室保存的M.bovis分离株复苏培养物用固体培养、PCR和恒温检测法3种方法进行鉴定.结果显示:3种方法都可以鉴定培养物中支原体的存在;与固体培养法相比,一步恒温检测法的结果用肉眼就能清晰可见;与PCR法相比,一步恒温检测法操作简单,实验周期短,但恒温检测法的特异性较差,不能区分不同种间的支原体.因此应采用PCR和恒温检测法相结合的方法进行鉴定.

为观察口服凝胶剂对腹泻犊牦牛的治疗效果,检测腹泻牛治疗前后和正常牛之间血清生化指标的变化,试验随机选取6～35日龄自然状态下腹泻犊牦牛12头和正常犊牦牛8头,对12例腹泻牛进行3d治疗并观察疗效;采集腹泻犊牛治疗前后及8头正常犊牛血清进行分析.结果显示,口服凝胶剂对犊牦牛临床腹泻的治愈率为75％(9/12),总有效率达到91.67％(11/12).血清生化结果显示,各组间Mg和CRE差异均不显著(
目前,氟对畜禽肠道形态发育影响的系统研究尚未见有报道.在机体的消化、吸收和防御功能中扮演重要角色的肠道却是最早和最易受到氟影响的部位.鉴于以上2个原因,试验选用1日龄艾维茵肉鸡健雏,饲以梯度剂量的高氟日粮,通过对肠道(十二指肠、空肠及回肠)病理学的观察以及形态学发育指标的检测,以衡量高氟对雏鸡肠道形态发育的影响,为进一步阐明氟对肠道发育的影响机制提供新的且具有学术价值的研究资料.通常认为完整的肠道
为了系统地研究一种抗病毒复方中药的颗粒剂制备工艺,该试验以绿原酸、表告依春和苦参碱的提取量为评价指标,首先筛选了金银花、板蓝根、苦参3味中药；然后采用单因素试验,考察料液比、浸泡时间、提取时间、提取次数和乙醇浓度等因素对金银花、板蓝根、苦参3味中药提取效果的影响,确定主要影响因素；并在该试验结果的基础上,采用正交试验,从单独提取和混合提取2个方面考察金银花、板蓝根、苦参3味中药的提取量,选择较优的
β-羟丁酸(BHBA)是血液中酮体的主要成分之一,在奶牛体内瘤胃发酵产生的丁酸可以经瘤胃上皮的作用转变为BHBA,经血液运输到乳腺后可作为合成乳脂肪的前体物参与脂肪酸的从头合成。多个研究表明,BHBA可以影响垂体激素分泌功能。然而,目前未见关于BHBA对奶牛腺垂体细胞(DCAPCs)激素分泌功能影响的研究。为了阐明BHBA对DCAPCs中GH、PRL表达和分泌的影响及机制,该研究采用RT-PCR、
