浅谈精细化管理在动物卫生检疫证照管理中的应用

检疫合格证明是动物产品溯源的重要途径,检疫证明的管理是否规范关系到动物卫生监督职能发挥的有效性。本文从检疫证照管理的具体实践中探讨引进精细化管理理念的优势,从而证明在精细化管理过程中,从"精细思维"的养成到"索证、验证、上缴核销"流程中的精细化操作,有效促进检疫证照管理的规范化、精细化,切实提高整个证照管理的科学性。     

小肽营养素对奶牛泌乳性能的影响

试验选择泌乳期中国荷斯坦奶牛32头,随机分为4组,A组(对照组)为基础精料日粮组;B、C、D组分别为基础精料日粮 0.1%、0.3%、0.5%小肽营养素。正试期28d。结果表明,添加0.1%、0.3%、0.5%小肽营养素后,奶牛头日平均产奶量分别提高1.67kg(6.38%)(P<0.05)、1.75kg(6.69%)(P<0.05)和1.64kg(6.27%)(P<0.05)。添加小肽营养素后,乳蛋白和乳脂率均有所提高,其趋势随小肽营养素添加量的增加而提高。添加0.1%、0.3%、0.5%小肽营养素后,奶牛头日净增效益3.52元、3.40元、2.86元。综合生产性能和经济效益,以添加0.1%-0.3%小肽营养素为适宜。     

Pharmacokinetics of mequindox and one of its major metabolites in chickens after intravenous, intramuscular and oral administration

Pharmacokinetics of mequindox and one of its major metabolites (M) was determined in chickens after intravenous (i.v.), intramuscular (i.m.) and oral administration of mequindox at a single dose of 10 (i.v. and i.m.) or 20 mg/kg b.w. (oral). Plasma concentration profiles were analyzed by a non-compartmental pharmacokinetic method. Following i.v., i.m. and oral administration, the areas under the plasma concentration-time curve (AUC(0-∞)) were 0.71±0.15, 0.67±0.21, 0.25±0.10 μg h/mL (mequindox) and 37.24±7.98, 36.40±9.16, 86.39±16.01 μg h/mL (M), respectively. The terminal elimination half-lives (t(1/2λz)) were determined to be 0.15±0.06, 0.21±0.09, 0.49±0.23 h (mequindox) and 5.36±0.86, 5.39±0.52, 5.22±0.35 h (M), respectively. The bioavailabilities (F) of mequindox were 89.4% and 16.6% for i.m. and oral administration. Steady-state distribution volume (V(ss)) of 1.20±0.34 L/kg and total body clearance (Cl(B)) of 13.57±2.16 L/kg h were determined for mequindox after i.v. dosing. After single i.m. and oral administration, peak plasma concentrations (C(max)) of 3.04±1.32, 0.36±0.13 μg/mL (mequindox) and 3.81±0.92, 5.99±1.16 μg/mL (M) were observed at t(max) of 0.08±0.02, 0.32±0.12 h (mequindox) and 0.66±0.19, 6.67±1.03 h (M), respectively. The results showed that mequindox was rapidly absorbed after i.m. or p.o. administration and most of mequindox was transformed to metabolites in chickens, with much higher C(max)s and AUCs of metabolite (M) than those of mequindox in plasma.     

汕头市猪场猪瘟和猪禽流感血清学监测报告

为了了解和掌握我市猪场的猪瘟免疫情况及感染高致病性禽流感疫病的可能性，我所分别于2005年2月和4月两次对全市范围内各类型的养猪场免疫猪瘟的猪只采集血清941份，进行猪瘟血清抗体监测和猪高致病性禽流感疫情血清学监测。现将监测结果报告如下。     

正大集团与中国农牧业、饲料业共成长

正大在中国近乎家喻户晓,在行业更是无人不知。正大集团作为由农业起步的多元化大型跨国企业,至今已有80多年的发展历史。正大集团第一代创始人谢易初先生1921年从广东澄海到泰国曼谷建立了正大庄菜籽行。谢易初先生虽然身在海外创业发展,但心中始终怀有一颗赤诚的中国心,所以他给四个儿子起名为正民、大民、中民、国民,中间字合起来是“正大中国”。经过谢家两代人的奋发努力,正大集团不断发展壮大。中国改革开放以后,正大集团是最早来华投资的外商企业之一。伴随着中国新时代的发展历程,正大集团已经成为外商在华投资企业中地域分布广、行…

Comparative analysis of proteomic profiles between endometrial caruncular and intercaruncular areas in ewes during the peri-implantation period

The endometrium of sheep consists of plenty of raised intercaruncular areas （IC）. In order to better understand aglandular areas called caruncular （C）, and intensely glandular the endometrium involved mechanisms of implantation, we used LC-MS/MS technique to profile the proteome of ovine endometrial C areas and IC areas separately during the peri-implantation period, and then compared the proteomic profiles between these two areas. We successfully detected 1740 and 1813 proteins in C areas and IC areas respectively. By comparing the proteome of these two areas, we found 170 differentially expressed proteins （DEPs） （P 〈 0.05）, functional bioinformatics analysis showed these DEPs were mainly involved in growth and remodeling of endometrial tissue, cell adhesion and protein transport, and so on Our study, for the first time, provided a proteomic reference for elucidating the differences between C and IC areas, as an integrated function unit respectively, during the peri-implantation period. The results could help us to better understand the implantation in the ewes. In addition, we established a relatively detailed protein database of ovine endometrium, which provide a unique reference for further studies.     

饲料企业制造成本系统控制模型

企业的竞争力来源于两个因素：一是品质．二是成本。通过精益生产．减少浪费．是最行之有效的控制成本的方法之一。制造成本是决定饲料企业经济效益和市场竞争力的一个重要因素．随着原料价格的不断攀升,企业的利润越来越低．降低生产成本．提高生产效率成为饲料企业的利润增长点。但在目前饲料行业中．中小型饲料厂比较多,固定资产投资比较小,现代化生产设备比较少,
