驴驹早期补饲模式研究

试验旨在研究早期补饲和提前隔离挤奶时间对驴驹生长发育指标的影响。选择平均出生时间2.37 d的德州驴公驴驹20头,按体重和出生时间接近的原则随机分为4组,每组5头,分别为对照组、试验组Ⅰ、试验组Ⅱ和试验组Ⅲ。对照组采用传统饲养方式,产后25日龄母子隔离挤奶,隔离期间给驴驹供给苜蓿干草;试验组产后15日龄挤奶,产后7日龄开始补饲教槽,10日龄开始在补饲精饲料+苜蓿干草,2次/d,30 min/次。精饲料的基础配比相同,试验组Ⅱ和试验组Ⅲ分别添加了5%和10%的代乳粉。在31~65日龄,给试验组精料中添加0.05%的微生态制剂。结果显示:在出生到30日龄的平均日增重比较中,对照组和试验组Ⅲ之间差异显著(P<0.05);试验组和对照组各阶段体尺指标差异均不显著;试验组各组的教槽效果与代乳粉的添加成正比;由于微生态制剂的添加,试验组Ⅰ、Ⅱ、Ⅲ的65日龄体重显著高于对照组(P<0.05),试验组各组之间差异不显著。试验结果表明,早期补饲可以促进驴驹的生长发育,并提前母驴的挤奶时间。     

补饲不同蛋白质水平精料对放牧绒山羊生产性能的影响

本文旨在研究补饲不同蛋白质水平精料对放牧绒山羊生产性能的影响情况。选用平均体重、上一年平均产绒量相近,2周岁左右的内蒙古绒山羊羯羊40只,随机分为4组,每组10只,其中1组为对照组,另外3组为试验组(简称Ⅰ组、Ⅱ组和Ⅲ组),试验组分别补饲3种不同蛋白水平(12%、24%和36%)的混合精料200g/d,对照组不补饲。结果表明,产绒量试验组与对照组之间差异不显著(P>0.05),但是,试验组内Ⅰ组(817.38±36.36g)显著高于Ⅲ组(760.25±40.34g)(P<0.05)。绒长度在绒生长旺盛期各月份均以试验Ⅰ组显著高于对照组和其它试验组(P<0.05)。绒生长旺盛期的各月份的绒细度和净绒率,各组间差异不显著(P>0.05),但是,从数据上可以看出各月份绒细度随着蛋白质水平的增加而增加。绒毛与粗毛重量百分比,绒生长旺盛期的各月份试验组均显著高于对照组(P<0.05)。粗毛的长度以试验Ⅱ组最长,试验Ⅰ组最短,但是各组间差异不显著(P>0.05)。含绒率9月份以试验Ⅰ组显著高于试验Ⅱ组和对照组(P<0.05),10月份和11月份各组间差异不显著(P>0.05)。试验各组绒山羊各月月末体重变化差异不显著(P>0.05)。总增重试验组显著高于对照组(P<0.05),试验Ⅰ组最高,对照组最低。(结论)由此,建议绒山羊绒生长旺盛期补饲200g含粗蛋白质12%混合精料。

Optimization of the system of medical service of students of Cadet Schools of the Ministry of Defense of the Russian Federation

One of the factors of the successful military career guidance Cadet schools students is preserving and promoting their health. Medical support of children and adolescents aged 10-17 years should include the full range of medical and preventive measures defined for this group. The state of providing outpatient care for pupils at the Cadet School in St. Petersburg was studied. These results show that full medical care in accordance with the standards can be based only on children's health clinics. It is important that the organization of medical support pupils cadet schools should be cooperate with civilian health care.

Estimation of accumulated dose of radiation by method of ESR-spectrometry of dental enamel of mammals

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P_1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method.     

Analysis of the results of the international comparison of activity measurements of a solution of Fe

The results of an international comparison of activity measurements of a solution of ⁵⁵Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a ⁵⁵Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.

The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison.     

Evaluation of the results of various technics of non-surgical therapy of varicocele

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood.
