仔犬主要感觉行为发育的观察

犬的感觉行为是犬最基本的行为构成,其发育是一个连续的过程.了解和掌握仔犬期(0-45日龄)主要感觉行为的发育特征,对提高仔犬感觉统合能力、行为发育、仔犬期的饲养管理水平和训练水平具有重要意义.     

研究犬的思维

犬如何形成思维和行为方式呢?布达佩斯Eotvos Lorand大学的Vilmos Csanyi指出,犬的天然环境是人类的家庭或人类的其它社会行为.因为犬与人类生活在一起,Csanyi相信人类会以一定的方式允许犬和人类一起生活,他同时认为犬对人类的情感和社会行为很感兴趣,并且尽量地学习和保持人类的这种习惯.因此,当其他人将注意力集中在类人猿的社会行为时,他的研究组却成了研究犬的先锋.

犬心理应激的生理和行为指示剂的研究进展

各种用途的犬广泛服务于人类社会的发展,紧密影响人类的生活。新异或威胁性环境、社会依恋的分离以及对犬的训练等均能导致犬出现心理应激,引起生理、行为和认知功能的改变,影响犬的工作性能和福利。本文重点介绍犬心理应激时,生理指示剂的确定和各种可能出现的行为改变。强调应关注犬的内心感受和心理需求,尽量减少犬的心理应激,改善认知功能,提高和改善犬的工作性能和福利状况。

犬的排泄行为

排泄行为(Elimmative Behaviour)是指与粪尿排出有关的行为。犬排泄粪便和尿液并不仅仅是一种排泄废物的动作,而且是犬与犬交往的一种重要手段,有着特殊的意义。正确认识犬盼排泄行为对搞好犬场卫生,使犬养成良好的家居文明习性有重要作用。作者根据长期观察所得,并参考有关资料,对犬的排泄行为作一简述,供同行参考。 1 仔犬的排泄行为仔犬的排泄行为是一个不断变化发展,日趋成熟的动态过程。18日龄前的仔犬并不

新训犬员“四做到”

新训犬员由于初次带犬，还不能很好的掌握犬的行为特点和生活习性，个别人甚至对犬存在畏惧心理，在操作技能上也是一片空白，有时会觉得无从下手。如何提高新训犬员的基本技能，笔者认为应做到以下四个方面：

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.     

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.

军犬鉴别中的嗅源培养和易出现的问题及对策

嗅源是军犬嗅觉作业训练的依据.军犬鉴别中嗅源能力的培养在整个鉴别训练中占有重要地位,关系到鉴别训练的成败和鉴别能力的提高.所以,军犬在嗅认嗅源时必须按照训犬员的指令充分、细致地感受嗅源气味,并且对嗅源气味产生兴奋反应.如何培养军犬充分嗅认嗅源以及及时解决嗅认过程中出现的问题,成为我们进行鉴别训练的关键.……
