狩猎时代之二:为猎而生

毫无疑问,随着14世纪欧洲古典时期的发展,狩猎已成为贵族们享乐生活以及彰显身份的最佳方式。猎犬们在狩猎中充分实现了自己的价值,因为本能、品种和训练能够使它们很好地完成这项任务。嗅猎犬是所有现代猎犬的鼻祖,它们从中世纪开始与人为伴,利用它们的本能帮助猎人     

伊维萨猎犬

正伊维萨猎犬(Ibizan Hound)又称依比沙猎犬、伊比桑猎犬,该犬耐力佳、快捷灵敏,在复杂的地形中依然非常快速,用视觉、听觉和嗅觉狩猎,并可以夜间狩猎,有指示和寻回猎物的本领。一、历史起源伊维萨猎犬历史悠久,最早可追溯公元前3000年,其起源于马略卡岛、伊比沙岛和地中海西部岛屿,祖先为法老犬种之一。据考证,该犬可能由腓尼基人,迦太基人和罗马人带到这些岛屿上。该犬曾一度被杯为法国猎     

初探寻血猎犬

寻血猎犬品种简介 寻血猎犬原产地比利时,是世界上品种最老、体型最大的狩猎犬之一。8世纪时,在比利时被饲养作狩猎犬。1066年,由威廉王带到英国,经过英国人几个世纪的选择育种使它已经在外观上与古代人所称赞的品种发生了变化,产生了今日的寻血猎犬。它的特征是如此的与众不同,以至于犬类学家对它的探索贯穿了整个犬类历史。

猎犬的养殖技术

<正>猎犬又名细犬,主要分平原犬和山地犬两种,猎犬的奔跑速度极快,时速每小时60公里左右,该犬主要用来捕捉野兔和其它小型陆地动物,很多狩猪爱好者养殖该犬用来增加收入。我县养犬户近几年养殖培育猎犬,经驯化后出售幼犬和野兔等猎物每年的纯收入超过万元,成为致富能手。l、引种猎犬为平原和山地产两种,引种时可根据自己的需要和当地地形分布选择,也可以引进平原和山地两种犬杂交繁     

狩猎时代之一:享乐贵族

古典时期,贵族们十分关注猎犬,到了中世纪的封建社会,猎犬更加受到重视。在中世纪的狩猎活动中,猎犬是必不可少的,并且因为主人出身贵族而获得了一席之地。狩猎是贵族们的主要消遣活动,可以在不发生战争时展现出他们的勇气和军事技能,而这项活动在很大程度上只限于贵族。在那个特权阶层享乐主义的年代里,人们重视猎犬,善待猎     

巴吉度猎犬

<正>巴吉度猎犬(Basset Hound)又称为巴塞特猎犬,或法国短脚猎犬。原产法国。是一种古老而高贵的猎犬品种。它源于法国血统,(也有的说是由埃及格雷特猎犬延续繁衍而来)几个世纪后在法国、比利时和英国发展起来。巴吉度猎犬主要用于追踪家免、野兔、鹿和其他任何能够靠足迹追踪的猎物。这种猎犬具有特殊的头部,凹陷的深褐色的大眼睛,     

养犬狩猎亦时尚

兔多犬旺,这是生态平衡的自然规律.野兔的大量繁殖,已成为农植物的一大祸害.养猎犬追捕野兔,在一些地区,已悄然成为部分农民闲暇时的一种时尚.

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.

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.……     

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.     

Observations on the Pathology of the Spleen of the Cat

Abstract— Lesions were found in the spleen of four of sixty-three cats examined post mortem in the department, and comprised two examples of lymphosarcoma, one of chronic fibrinous peritonitis and one of subcapsular haematoma. Abnormalities were found in two cat spleens received from veterinary surgeons in general practice. In one cat the abnormalities were an haemangiosarcoma with secondary deposits in the liver and in the other extensive mast cell infiltration. In addition lesions were detected in the spleen of three of eighty-seven cats examined post mortem in general practice. The lesions were: multiple secondary deposits of adenocarcinoma from a primary tumour of the mammary gland, a ruptured spleen and a foreign body below the splenic capsule. Résumé— L'examen microscopique de soixante-trois chats pratiqué dans le service a permis de rencontrer quatre fois des lésions de la rate, dont deux lymphosarcomes, une péritonite capsulaire fibrineuse et un hématome sous-capsulaire. D'autre part des lésions ont été trouvées dans deux rates de chat expédiées par des vétérinaires exerçant en pratiaue générale. Chez un chat il s'agissait d'un htmangiosarcome avec métastases hépatiques et chex l'autre d'une infilt ation diffuse par des mastocyta. De plus, on a rencontré des llésions dnas la rate de trois chats parmi quatre-vingt sept autopsies effectuées dans le cadre d'une clientèle génárale. Ces iésions étaient dés métastases multiples d'un adénocarcinome dont la tumeur primitive siègeait dam la glande mammaire, une rupture de la rate et un corps érangers sou capsulaire. Zusammenfassung— Läsionen der Milz wurden bei vier von dreiuiidsechzig in dieser hbteilung sezierten Katzen gefunden, und zwar in zwei Fällen ein Lymphosarkom, in einem Falle eine chron-ische fibrinöse Peritonitis und in einem ein subkapsuläres Hématom. Anomalien fanden sich auch in der Milz von zwei Katzen, die aus der tierxrztlichen Praxis eingesandt wurden. Bei der einen Katze war dies ein Hämangiosarkom mit Metastasen in der Leber, bei der anderen eine weitläufige Infiltration der Mastzellen. Außerdem wurden bei drei von siebenundachtzig in der Praxis sezierten Katzen Milzläsionen gefunden. Diese bestanden am multiplen Metastasen eines Adenokarzinoms der Brustdrüse, einer Milzzerreissung und einem Fremdkörper unterhalb der Milzkapsel.
