以内蒙古鄂托克前旗的大叶槐为试验材料,同时选择羊草和苜蓿为对比,通过常规营养成分分析、活体外发酵产气、两级离体消化、尼龙袋等试验,对其营养价值进行综合评定。结果表明,从常规分析来看,0.8~1.2m高的大叶槐蛋白质含量最高,其次为苜蓿;从体外发酵参数来看,无明显差异;从体外消化率来看,0.8~1.2m高的大叶槐蛋白质消化率低于苜蓿,但高于羊草和其他2种槐树;从半体内降解率来看,0.8~1.2m高的大叶槐蛋白质降解率仅低于苜蓿,而高于其他3种饲料。综合各试验,可发现0.8~1.2m高的大叶槐更适合用作蛋白质饲料,而不应用作纤维性饲料。 相似文献

The determination of enzymatic activity of cholinesterase is a useful diagnostic method to detect exposure to anticholinesterase
compounds in human and in veterinary medicine. We validated a modification of the Ellman method in canine serum and applied
it to the diagnosis of dogs poisoned with anticholinesterase substances. The method used butyrylthiocholine as substrate and
potassium hexacyanoferrate as chromophore. The reference range calculated on 60 clinically healthy dogs was set between 3405
and 6561 U/L (chi-square test for normal distribution, p > 0.05). The overall mean intra-assay and inter-assay coefficients
of variation were 0.53% and 3.83%, respectively. The assay was linear when using two sera with 12 538 U/L and 6604 U/L serum
cholinesterase activity (r2=0.997 and 0.999, respectively). The mean recovery values of pooled sera with a mean pseudocholinesterase (PChE) activity of 12
081 U/L and pooled sera with a mean PChE activity of 3415 U/L were 103.5% and 102.8%, respectively. Six dogs with a diagnosis
of anticholinesterase compound intoxication showed a decrease in cholinesterase activity of at least 50% of normal activity
with a mean ± SD of 487 ± 291 U/L ranging from 169 to 847 U/L. This technique conforms to the current standard for precision,
linearity and accuracy and is a useful method for the complementary diagnosis of organophosphate or carbamate insecticide
intoxication in dogs. 相似文献

Tumour‐associated macrophages (TAMs) have already been associated in human breast cancer to a poor prognosis. As a part of a tumoural microenvironment, TAMs have an important contribution influencing neoplastic progression. Hitherto, in canine mammary tumours (CMT) the prognostic value of TAMs has not been reported. In this study, MAC387 immunohistochemical expression was evaluated in 59 CMTs (20 benign and 39 malignant). The TAM value was significantly higher in malignant than benign CMT (P = 0.011). In malignant CMT, TAMs were associated with skin ulceration (P = 0.022), histological type (P = 0.044), nuclear grade (P = 0.031) and tubular differentiation (P = 0.042). The survival analysis revealed a significant association between tumours with higher levels of TAMs and the decrease in overall survival (P = 0.030). TAMs have proven to have a prognostic value. These findings suggest the future possibility of using TAMs as a novel therapeutic target in CMT. 相似文献

旨在研究微小miR-502(cfa-miRNA-502)在犬乳腺癌组织中的表达情况及其临床意义。采用实时定量PCR方法检测30例犬乳腺癌组织及癌旁正常组织中miR-502的表达水平,分析miR-502表达与犬乳腺癌组织临床病理特征(年龄、肿瘤大小、组织学分级和转移)的关系。结果显示:与癌旁组织相比,犬乳腺癌组织中miR-502的表达水平显著升高,差异具有统计学意义(P<0.01);miR-502表达与犬乳腺癌的组织学分级与转移有关(P<0.05),但与年龄和肿瘤大小无关(P>0.05)。本研究提示miR-502在犬乳腺癌组织中表达上调,其表达与犬乳腺肿瘤的发生、发展有一定关系,miR-502可能作为犬乳腺癌诊断的肿瘤标记物。 相似文献

针对2013年-2015年广西11个地级市的宠物犬群进行犬流感调查,发现钦州犬流感感染的阳性率高达40%,除百色和玉林外,其余的阳性率在14.29%~34.29%之间,结果表明犬流感在广西呈普遍流行态势。此外,对不同品种、性别和生长阶段的宠物犬感染 CIVs 进行了调查分析。结果发现,任何品种和性别的宠物犬都可以感染犬流感病毒,其中青年阶段(6月龄~2岁)的犬最为易感。2015年的调查中,成年犬(2岁~7岁)成为潜在的易感群体。结果为更好地指导宠物医生采取有效的措施控制疾病发生,从而切断宠物犬作为中间传播者的作用,为防控人类大流感的暴发提供了间接帮助。 相似文献

醋糟的营养价值及其在饲料生产中的应用 总被引:5,自引:0,他引:5
醋糟是固态发酵法酿造食醋过程中的副产物,其成分会因原料和加工工艺的不同而存在差异。在畜禽养殖中,醋糟主要作为一种非常规饲料原料直接或者经发酵处理后应用于动物饲料中。近年来也有醋糟被用作生产纤维素酶和植酸酶的研究报道。虽然在畜禽养殖中已经得到一定程度的应用,但是目前大部分的醋糟还是被闲置。醋糟的纤维含量偏高,粗蛋白含量偏低,直接作为饲料原料饲喂畜禽营养价值较低。这可能是限制醋糟在畜禽养殖中应用的主要原因之一。目前,醋糟尚不能被充分利用而造成资源浪费和环境污染,迫切需要进一步深入和系统地挖掘其应用潜力。 相似文献

Evaluation of the modified Glasgow Prognostic Score to predict outcome in dogs with newly diagnosed lymphoma 下载免费PDF全文

The modified Glasgow Prognostic Score (mGPS) assigns a numerical value (0–2) from pre‐treatment serum concentrations of C‐reactive protein (CRP) and albumin to predict patient outcome. CRP and albumin were evaluated in 77 untreated dogs with lymphoma to determine the relationship of mGPS to clinicopathological parameters and whether it could predict progression‐free (PFS) and overall survival (OS) in treated dogs. mGPS distribution was significantly associated with clinical stage, substage b, weight loss, gastrointestinal disturbances and lethargy at presentation. On univariate analysis, mGPS was significantly associated with OS and PFS, with shorter median survival times for mGPS 2 compared to mGPS 0 and 1 combined. Hypoalbuminaemia significantly reduced OS and PFS, however increased CRP had no effect. Only clinical stage was significantly associated with OS and PFS on both univariate and multivariate analysis. mGPS has potential prognostic value for canine lymphoma , but further studies are needed. 相似文献
