Ziel der vorliegenden Arbeit war es, zu uberprufen, ob beim Hengst erhobene dopplersonographische Messungen der Aa testiculares reproduzierbare Ergebnisse erbringen und inwieweit der testikulare Blutfluss temporaren (taglichen, saisonalen) Schwankungen unterliegt bzw. welchen Einfluss der Deckeinsatz auf den Blutfluss hat. Ferner wurde darauf geachtet, ob Zusammenhange zwischen dem testikularen Blutfluss und der Spermienproduktion bzw. der Fertilitat der Hengste bestehen. Insgesamt wurden 40 Hengste (Alter: 9,1±4,2 Jahre) zwischen Juli 2002 und Januar 2003 erfasst. Von allen Zuchthengsten wurde bis Juli 2002 Samen gewonnen, danach wurde eine achtwochige Deckruhe eingehalten. Zwischen Oktober 2002 und Januar 2003 wurde bei 24 Hengsten (DR) die Deckruhe fortgesetzt, wahrend von 16 Hengsten (DE) dreimal wochentlich an den Tagen Montag, Mittwoch und Freitag Samen zum Zwecke der Kryokonservierung gewonnen wurde. Es wurden farbdopplersonographische Untersuchungen der Aa. testiculares im Samenstrang durchgefuhrt. Die Quantifizierung des Blutflusses erfolgte mit Hilfe des Pulsatility Index (PI) und des Blutflussvolumens (BFV). Sowohl die PI- (Median: 2,2; Medianabweichung MAD: 0,6; Min.: 0,8; Max.: 6,4) als auch die BFV-Werte (Median: 33,4 ml/min; MAD: 6,5 ml/min; Min: 14,9 ml/min; Max: 80,4 ml/min) zeigten eine hohe Variabilitat. Einen Zusammenhang liesen die beiden Blutflussparameter nicht erkennen (r=-0,10; p>0,05). Die Intra-Class-Korrelationskoeffizienten wiederholter Untersuchungen waren relativ hoch (PI: 0,82 bzw. BFV: 0,85). Der testikulare Blutfluss beim Hengst unterlag keinen tageszeitlichen und wochentlichen Schwankungen (p>0,05). Wahrend sich die BFV-Werte der Monate Juli, Oktober und Januar nicht unterschieden (p>0,05), fiel der PI zwischen Oktober und Januar ab (p 0,05). Im Gegensatz dazu bestand eine positive Beziehung (r=0,56; p 0,05). Die durchgefuhrten Untersuchungen zeigen, dass die Dopplersonographie beim Hengst eine geeignete Methode zur Bestimmung des testikularen Blutflusses darstellt. Es wurde zwar ein positiver Zusammenhang zwischen testikularem Blutflussvolumen und der Gesamtspermienzahl nachgewiesen; bei fertilen Hengsten bestand jedoch kein Zusammenhang des PI zu spermatologischen Parametern und der Fertilitat

There is little published information concerning microbial diversity in the horse gut. However, microbial instability can influence gut lumen pH and lactate accumulation, both of which have been implicated in the occurrence of laminitis and colic. In this study three substrates, hay (H), oats (O) and a 50:50 hay:oats (DM basis) mixture (HO) were used to evaluate in vitro microbial fermentative activity in four sections of the equine gut.

Skeletal injuries in performance horses are quite common. Research investigating ways to decrease injuries has been limited due to difficulty in non-invasively measuring the response of bone to a given treatment. With the use of biochemical markers of bone turnover, more projects are being conducted and advancements in improving bone health are occurring. However, such assays are expensive and researchers often need to make decisions as to when their use is justified. By reviewing the responses of bone markers in nutritional studies and comparing them to responses in exercise studies, the objective is to determine whether bone is more likely to respond to a dietary or exercise treatment.

Forty farm/stables in Bavaria where horses (mainly riding horses, German Warmblood) are kept were visited for sampling. The horses were used as leisure horses or for competitions. The individual ration components of a selected horse were weighed. The quantity and composition of the mineral supplement was also recorded. The horses’ live weight was estimated according to the equation given by Carrol and Huntington (1988), where LW (kg) = (girth, cm)2 x body length, cm /11900. Age and energy expenditure (light, medium or heavy work) were noted. The actual supply of energy, crude protein and minerals was calculated from the weight of the individual component in the ration and the chemical analyses (Schwarz et al. 2005) of the feeds used, and these results were compared with the recommendations for rations which would meet their requirements (GfE, 1994).

During the dioestrous phase of the mare’s oestrous cycle, a cohort of 8-12 ovarian follicles is stimulated to develop by the action of pituitary FSH. During the ensuing oestrus, a “dominant follicle” is selected to continue maturation towards ovulation under the influence of pituitary LH (Evans and Irvine 1975), while the other follicles in the cohort become atretic. Morphological and biochemical changes in the follicular wall result in follicular rupture (ovulation) through the ovulation fossa and the release of the oocyte surrounded by cumulus cells into the oviduct. Ovulation failure has been well documented in the mare (Ginther 1979, Bosu et al. 1982, Ginther and Pierson 1989, Daels and Hughes 1993, Pierson 1993, McCue and Squires 2002), the most common form of which is the development of an anovulatory haemorrhagic follicle (AHF) where the follicle fails to rupture and its cavity becomes increasingly filled with blood. Such haemorrhagic follicles are commonly observed during the transitional phases in Spring and Autumn (Ginther 1992, Nunes et al. 2002), when the secretion rates of both gonadotropins and ovarian steroids are declining (Daels and Hughes 1993). Their occurrence during the breeding season greatly reduces breeding efficiency and the aim of the present study was to document the incidence of AHFs in an experimental herd of mares undergoing repeated pharmacological shortening of their oestrous cycles.

在母马发情周期的发情期，一组8-12个卵泡在垂体促卵泡刺激素的作用下被刺激发育。在随后的发情期，选择一个“优势卵泡”在垂体LH的影响下继续成熟排卵(Evans和Irvine 1975)，而队列中的其他卵泡则变得闭锁。卵泡壁的形态和生化变化导致卵泡破裂(排卵)通过排卵窝，被卵丘细胞包围的卵母细胞释放到输卵管中。排卵失败在母马中有很好的记录(Ginther 1979, Bosu等人1982,Ginther和Pierson 1989, Daels和Hughes 1993, Pierson 1993, McCue和Squires 2002)，最常见的形式是无排卵性出血性卵泡(AHF)的发展，其中卵泡未能破裂，其腔内越来越充满血液。这种出血性卵泡通常出现在春秋两季的过渡阶段(Ginther 1992, Nunes et al. 2002)，此时促性腺激素和卵巢类固醇的分泌率都在下降(Daels and Hughes 1993)。它们在繁殖季节的发生大大降低了繁殖效率，本研究的目的是记录在一群反复服用药物缩短其发情周期的母马中发生ahf的情况。材料与方法

Separation of X-and Y-chromosome bearing spermatozoa to pre-select the sex of offspring is now possible in most large farm animals including horses. Spermatozoa are separated by flowcytometry based on the amount of DNA that differs between the both sex chromosomes. The purity of the sex selection is very high, however the number of spermatozoa being separated is limited. Therefore AI strategies have to be modified in order to get normal pregnancy rates even with low dose insemination. Recently it was shown that hysteroscopic insemination into the tip of the uterus horn or at the uterine papilla results in acceptable pregnancy rates. This review summarizes the data being provided in literature when both technologies, sperm sexing and low does insemination, are combined, employing freshly collected sorted semen, fresh semen stored for 18h prior to sorting and sorted, frozen/thawed spermatozoa. Several foals have been born so far, but the technology needs further improvement before being advertised for commercial use.

A five year old Swiss Warmblood gelding was presented with unilateral, chronic, mucopurulent nasal discharge. Clinical, radiographic and computertomographic examinations showed a mass in the ventral meatus of the nasal cavity. The mass had connection to the root of the fourth premolar tooth. During surgery, the fourth premolar tooth and the mass were completely removed. A rectangular bone flap of the maxillary bone was performed to gain access to the apex of the tooth. The fourth premolar tooth had to be repelled initially before the neoplasia could be isolated and removed through the surgical approach. The large opening between the oral and the nasal cavities was closed with a silicon-dental packing. The histologic examination of the neoplastic tissue revealed an ostelipoma. Eight weeks later the silicon-plug was removed orally. Four months after the surgery the horse was presented again with an unilateral, purulent nasal discharge. In the mean time a fistula developed between the oral cavity and the maxillary sinus. Clinically as well as radiographically the patient exhibited all the signs of a chronic sinusitis of the maxillary and frontal sinus. In a second surgery the fistula was closed with a methylmethacrylat-plug. After another 2 months the horse was presented without any complications. The methylmetacrylat-packing was removed 3 months later.

Auer","doi":"10.5167/uzh-61517","DOIUrl":"https://doi.org/10.5167/uzh-61517","url":null,"abstract":"A five year old Swiss Warmblood gelding was presented with unilateral, chronic, mucopurulent nasal discharge. Clinical, radiographic and computertomographic examinations showed a mass in the ventral meatus of the nasal cavity. The mass had connection to the root of the fourth premolar tooth. During surgery, the fourth premolar tooth and the mass were completely removed. A rectangular bone flap of the maxillary bone was performed to gain access to the apex of the tooth. The fourth premolar tooth had to be repelled initially before the neoplasia could be isolated and removed through the surgical approach. The large opening between the oral and the nasal cavities was closed with a silicon-dental packing. The histologic examination of the neoplastic tissue revealed an ostelipoma. Eight weeks later the silicon-plug was removed orally. Four months after the surgery the horse was presented again with an unilateral, purulent nasal discharge. In the mean time a fistula developed between the oral cavity and the maxillary sinus. Clinically as well as radiographically the patient exhibited all the signs of a chronic sinusitis of the maxillary and frontal sinus. In a second surgery the fistula was closed with a methylmethacrylat-plug. After another 2 months the horse was presented without any complications. The methylmetacrylat-packing was removed 3 months later.","PeriodicalId":54626,"journal":{"name":"Pferdeheilkunde","volume":"18 1","pages":"169-172"},"PeriodicalIF":0.3,"publicationDate":"2002-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70657197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
