动物科学专业本科毕业论文“层级组织化”教学指导模式改革探索——以云南农业大学动物科学专业本科毕业论文教学指导为例

毕业论文教学环节是动物科学专业培养方案中的重要组成部分,在人才培养体系中占有十分重要的地位。为了提高本科生毕业论文质量,云南农业大学动物科学技术学院饲料工程教研组以动物科学专业特点为出发点,构建了"层级组织化"的毕业论文教学指导模式,将本科生、研究生、指导教师和教研组紧密联为一体,从选题、开题、试验、论文撰写、答辩等多个环节进行教学改革,特别注重学生的科研能力、创新能力和团队协作能力的培养,经实践应用,本科毕业论文质量和学生的综合素质均有明显提高。     

导师制对动物科学专业学生毕业论文成绩的影响

收集扬州大学动物科学专业2007-2013年推行毕业论文导师制以来共770篇毕业论文相关信息,同时采用多因素方差分析法对影响毕业论文成绩的相关因素进行分析,结果表明:本科生导师制极显著提高了动物科学专业本科生毕业论文成绩(P0.01);导师制下,毕业论文题目类型、导师个人和导师职称显著影响毕业论文成绩(P0.05),而毕业论文题目来源、导师学历和导师是否为博士生导师或硕士生导师对本科生毕业论文成绩无显著影响(P0.05)。学生尽早接触科研、开展大学生科研训练计划、引进优秀高水平博士人才、提高指导教师的学术水平和敬业精神、制定完善的毕业论文规章制度,并进行周密的组织,均有助于学生毕业论文质量的提高。     

动物科学专业毕业实习面临的问题及对策

毕业实习在培养大学生探求真理和知识，强化社会意识，进行专业综合训练，提高实践能力和综合素质等方面具有十分重要的作用。同时毕业论文的质量也是衡量教学水平，审核学生毕业与学位资格的重要依据。现就动物科学专业毕业实习面临的问题及对策谈一些个人想法。

影响动物科学专业生产课教学效果的原因分析及改革建议

生产课是动物科学专业的必修专业课程,对学生积累生产实践经验、培养分析解决问题的能力和综合素质起着重要作用,但目前在教学中尚存在许多问题。本文对影响动物科学专业生产课教学效果的原因进行分析并提出相应的改革建议,以解决教学中面临的问题,提高专业课的教学效果和质量。     

动物科学专业本科人才培养目标之我见

动物科学专业本科人才培养目标是确定动物科学专业本科课程教学方案的依据,是培养什么质量的动物科学专业本科人才的指导思想。动物科学专业的人才培养目标应包含如下几个重要方面。首先,动物科学专业人才培养目标应着眼于人文精神和合作精神的培养。其二,应注重基础课的教学,使学生获得终生学习的能力。其三,应促进学生的主动性思维,而不是让学生被动地接受知识的传授。其四,应提高学生的实践动手能力。最后,应在本科教学阶段继续提高动物科学专业本科生的语言技能。本文对如上方面逐一进行了阐述。     

动物生产类专业实践教育教学模式改革的路径分析

实践教学在培养学生创新实践能力中起到至关重要的作用,加强实践教学是"新农科"建设背景下提升农林专业内涵建设的重要举措。为进一步优化动物生产类专业的实践教学体系,对扬州大学近4届毕业生进行了专业实践教学满意度的问卷调查。调查结果显示,学生对动物科学专业教学实践条件和师资力量的满意度较高,但是对生产实习和毕业论文实习等实践教学模块的满意度相对较低。根据本次调研结果,提出了动物生产类专业加强实践创新人才培养的举措,包括加强建设教学实验室和实习实训基地,推进实践教学模式改革,健全覆盖动物生产所有环节的生产实践教学体系,加强创新创业实践能力训练等。

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.

本文检测腹泻犊牛的直肠内8种主要正常菌群的变化,并与健康犊牛进行对比。结果发现,犊牛腹泻时,大肠杆菌、双岐杆菌和乳杆菌变化较大,而其它菌群变化较小。腹泻或将腹泻时,大肠杆菌数增加,双岐杆菌和乳杆菌数下降。腹泻康复或即将康复时,大肠杆菌减少,双岐杆菌、乳杆菌数增加。     

陕北白绒山羊繁育中心羊场绒山羊日粮的评价

试验选择陕北白绒山羊繁育中心羊场的成年健康母羊（怀孕前期）16只,育成母羊13只,育成公羊13只,空腹称重。测定每只羊1d的采食量,计算其摄入的营养成分含量,并与原苏联绒用山羊饲养标准比较,进行饲养水平评价。结果显示,与饲养标准比较,陕北白绒山羊繁育中心羊场的育成母羊代谢能高2．68MJ,粗蛋白低59．29g,钙低3．00g,磷低1．52g;育成公羊代谢能高3．47MJ,粗蛋白低81．92g,钙低4．42g,磷低2．62g;成年母羊代谢能高2．51MJ,粗蛋白低91．33g,钙低3．09g,磷低1．93g。结合羊的体况综合评价饲养水平基本合理,但尚需要按饲养标准增加粗蛋白、钙、磷等营养物质的供给量。     

Evidence for the non-involvement of the uterus in the lifespan of the corpus luteum in the cyclic dog

Progesterone levels in peripheral blood of dogs were analysed during the cycle in which hysterectomy (n = 5) or sham surgery (n = 3) was performed as well as during the cycle of dogs (n = 5) hysterectomized at least one year prior to this study; the data were compared with the findings in control dogs (n = 3). The averages of the duration of the luteal period observed in the three experimental groups were not significantly different from those of control dogs. Immediately after surgery, the progesterone level decreased from 25 to 50% of the presurgical level, but returned to presurgical level in about four days. Prolactin levels were elevated for about 30 h after surgery. Nevertheless, the averages of the mean prolactin levels for each animal during the luteal period of the experimental groups were not significantly different from those of control dogs. It is concluded that in the dog, the uterus is not involved in the lifespan of the cyclic corpus luteum.
