反相高效液相色谱法测定饲料及饲料添加剂中阿朴酯的含量北大核心

研究旨在建立一种反相高效液相色谱(RP-HPLC)法检测饲料及饲料添加剂中阿朴酯含量的方法。饲料或饲料添加剂样品经水、甲基叔丁基醚-甲醇溶液提取,样液在50℃水浴中经氮气吹干(添加剂样品直接稀释),使用流动相稀释,定容,上机检测。结果显示,采用C30色谱柱、流动相甲基叔丁基醚-甲醇比例为15∶85时,阿朴酯能够与其他类胡萝卜素很好地分离。试验所用方法在0.04~10.00 mg/L浓度范围内线性关系良好,相关系数为0.999 98。样品中添加阿朴酯的加标回收率为86.0%~99.8%,方法检出限为0.15 mg/kg,方法定量限为0.40 mg/kg。研究表明,试验所用方法操作简单、灵敏度高,能够检测饲料及饲料添加剂中的阿朴酯。

饲料和饲料添加剂中蜡样芽孢杆菌分离鉴定及其呕吐毒素基因检测

为了掌握饲料及饲料添加剂中蜡样芽孢杆菌分布及其呕吐毒素基因携带情况,从规模化饲料生产企业采集饲料及饲料添加剂样品246批。通过细菌分离、纯化、PCR检测和BD PhoenixTM-100全自动微生物鉴定系统鉴定,共分离蜡样芽孢杆菌63株,分离率为25.6%,从混合型饲料添加剂中检出4株含芽孢杆菌呕吐毒素基因,携带率为13.3%。试验结果表明,饲料和饲料添加剂中存在蜡样芽孢杆菌,尤其是含呕吐毒素蜡样芽孢杆菌污染风险。

增压溶样TCP-AES法同时测定多种元素含量

随着我国畜牧业生产由粗放型向集约型转变,饲料工业蓬勃发展,各种配合饲料、浓缩饲料、预混合饲料及饲料添加剂纷纷上市. 快速、准确检测饲料及添加剂中各种营养成分,对研究饲料配方、控制产品质量都显得尤为重要.现行饲料及添加剂中营养元素如Fe、Mn、Ca、P普遍采用分光光度法、容量滴定法和原子吸收分光光度法测定,这些方法都是单元素分析,时间长,手续繁琐,试剂耗量大,而且测试范围有限,在实际工作中应用很不方便.用电感耦合等离子体发射光谱(ICP-AES)测定,灵敏度高,干扰少,动态范围宽,能用一份试液同时检测从低含量到高含量的多种元素,省时省力.我们采用增压溶样技术消解样品,以ICP-AES法同时测定饲料及添加剂中Cu、Fe、Mn、Zn、Ca、P元素含量,取得满意结果. 并对样品的预处理、元素间的干扰、分析波长的选择等进行广研究,对ICP工作条件进行了优化,并用此法测定了标准参考物质,结果与推荐值一致.

The influence of the width of the saddle tree on the forces and the pressure distribution under the saddle

As there is no statistical evidence that saddle fit influences the load exerted on a horse's back, this study was performed to assess the hypothesis that the width of the tree significantly alters the pressure distribution on the back beneath the saddle. Nineteen sound horses were ridden at walk and trot on a treadmill with three saddles differing only in tree width. Kinetic data were recorded by a sensor mat. A minimum of 14 motion cycles were used in each trial. The saddles were classified into four groups depending on fit. For each horse, the saddle with the lowest overall force (LOF) was determined. Saddles were classified as "too-narrow" if they were one size (2 cm) narrower than the LOF saddle, and "too-wide" if they were one size (2 cm) wider than the LOF saddle. Saddles two sizes wider than LOF saddles were classified as "very-wide". In the group of narrow saddles, the pressure in the caudal third (walk 0.63 N/cm(2)+/-0.10; trot 1.08 N/cm(2)+/-0.26) was significantly higher compared to the LOF saddles (walk 0.50 N/cm(2)+/-0.09; trot 0.86 N/cm(2)+/-0.28). In the middle transversal third, the pressure of the wide saddles (walk 0.73 N/cm(2)+/-0.06; trot 1.52 N/cm(2)+/-0.19) and very-wide saddles (walk 0.77 N/cm(2)+/-0.06; trot 1.57 N/cm(2)+/-0.19) was significantly higher compared to LOF saddles (walk 0.65 N/cm(2)+/-0.10/ 0.63 N/cm(2)+/-0.11; trot 1.33 N/cm(2)+/-0.22/1.27 N/cm(2)+/-0.20). This study demonstrates that the load under poorly fitting saddles is distributed over a smaller area than under properly fitting saddles, leading to potentially harmful pressures peaks.     

Monitoring of the mare during the perinatal period at the clinic and in the stable

Complications in late gestation are challenging problems for the equine clinician and are causes of considerable distress to owners. Health problems in a pregnant mare in each stage of gestation can adversely affect the pregnancy. It is important to obtain a thorough history and perform a detailed and systematic examination of the pregnant mare so that the mare may be classified as normal or high-risk. However, even after a thorough examination, practitioners may face problems with the interpretation and assessment of risk. Normal mares should foal in the stable or pasture. Mares classified as having a high-risk pregnancy need to be monitored precisely for signs of oncoming foaling with attendance of trained personnel when labour begins. A valuable method for monitoring of the high-risk mare is assessing fetoplacental well-being. Fetoplacental well-being is most accurately assessed with ultrasonography as well as several available hormone profiles. We are proposing our scoring system of the mare's health, which may be useful in the assessment of risk during pregnancy and help clinicians to decide whether sending the mare to the clinic is reasonable or unnecessary.

Harnessing the genetic toolbox for the benefit of the racing Thoroughbred

The understanding and application of genetics have grown extremely quickly since it has become possible to sequence the whole genome of an organism. The human genome sequence was completed in 2001 and that of the horse in 2007. The significance of this is that it makes it more feasible to explain how both genetically simple and complex traits are transmitted from one generation to the next and, therefore, to make informed breeding decisions, modify how horses are managed and trained to minimise the risk of disease and injury, and improve methods of prevention, diagnosis and treatment of many conditions. The science of genetics/genomics will continue to grow internationally, limited only by the funds available. The application of the science to man, horses and other species raises very complex moral and commercial issues. Thoroughbred breeders are perceived by some as resistant to change, but their apparent intransigence is often based on a genuine concern for the integrity of the breed. By taking control of the application of the advances in genetics, the Thoroughbred industry potentially has the opportunity to improve both the health and performance of Thoroughbreds. If, however, the science is applied in an uncoordinated manner, driven by commercial interests with no underlying concern for the horses themselves, there is a very real risk that breeders, the Thoroughbred breed and individual horses will all suffer as a consequence.
