Abstract. The feasibility of including individual records on correlated traits in a family selection programme which aims to increase resistance to furunculosis in Atlantic salmon was studied; markers were selected because of their potential role in the pathogenesis of the disease. Fibrinogen and α₂-antiplasmin both show genetic variation; both are correlated with survival after challenge with Aeromonas salmonicida , the correlation being 0·44 and 0·37 ( P < 0·05), respectively, and it is possible to measure both on a large scale at low costs. Contrary to α₂-antiplasmin, fibrinogen was negatively correlated with survival due to furunculosis within the 10 most resistant families and within the 10 most susceptible families in contrast to an overall positive correlation. This inconsistency could be attributable to the presence of different allelic phases in different families, and of major linked loci influencing survival and fibrinogen levels. Thus, only α₂-antiplasmin fulfils the requirements for a marker trait for resistance to the disease suitable for individual selection at the population level, whereas the use of fibrinogen would be restricted to within family selection. The full statistical model explained 51% of the variation in resistance to furunculosis, and α₂-antiplasmin contributed 15% to this variation when considered as a separate entity. Thus, the additional gain from including individual records on α₂-antiplasmin in a family selection programme could be significant.  相似文献

Behavior of Mustela putorius furo (the domestic ferret).     

S W Boyce  B M Zingg  T L Lightfoot 《Veterinary Clinics of North America: Exotic Animal Practice》2001,4(3):697-712

Behavior patterns exhibited by the domestic ferret, although similar to its wild cousins, are distinctly domestic in nature. Domestic ferrets use many different types of behaviors, including body posturing, animations, vocalizations, and scent markings. These behaviors may differ somewhat from ferret to ferret. The domestic ferret is best understood by observation and recognition of its behavior patterns and interactions as it plays and communicates with both humans and animals within its home environment. As with all other species of animals kept as pets, the clinician will be greatly benefited by urging the pet owner to regularly note typical behavior patterns for their individual pet. Following is a brief summary of behavioral changes noted in domestic ferrets that may aid the owner or keeper in the detection of potential illness or injury: A normally active ferret suddenly becoming quiet or vice-versa Any sudden increase or decrease in daily food and water intake Routine behaviors performed out of context or order, especially in older animals Any sudden increase or decrease in the speed at which routine behaviors are performed (such as urination, defecation, grooming, food, or water intake) Any sudden increase in the effort required to perform normal or routine behaviors Any sudden changes in personality or attitude toward other ferrets or toward other animals or people. The previous information was gathered over the last 15 years from personal observations, experiences, and studies of ferrets in the shelter, home, and animal hospital environments. This information regarding ferret behavior can assist the veterinarian in differentiating between normal and abnormal behaviors in domestic ferrets. This increased understanding of ferret behavior can aid in the diagnosis of injury and disease and assist the veterinarian in educating clients regarding ferret behavior, care, and recognition of potential disease.  相似文献

THE DURATION OF THE OESTROUS CYCLE OF EWES AFFECTED WITH CLOVER DISEASE     

N. R. Adams B.V.Sc.  Ph.D.  R. J. Lightfoot B.Sc.Agric.  Ph.D.  A. J. Charlick 《Australian veterinary journal》1975,51(6):306-309

Oestrous cycles in ewes affected with clover disease were compared with those for control animals at two locations. Significantly fewer diseased ewes were observed in oestrus. There was a significant increase in variability of oestrous cycle duration in the diseased ewes at one location. Some of the cycle irregularities could be related to gross lesions in the internal genitalia. Despite these findings, there was no association between oestrous cycle abnormalities and previous fertility records, suggesting that they are of little consequence to the infertility of clover disease under field conditions.  相似文献   

Molecular epidemiology of Salmonella Heidelberg in an equine hospital   总被引：1，自引：0，他引：1

From 1992 to 1997, multi-drug resistant (MDR) Salmonella Heidelberg isolates were cultured from a number of horses hospitalised in a veterinary hospital in Victoria, Australia. To examine the relationships between the cases, 28 isolates from the hospital were compared by pulsed field gel electrophoresis (PFGE), IS200 element profiles, antimicrobial resistance patterns, plasmid profiles and phage typing. The PFGE patterns following digestion with XbaI and BlnI restriction endonucleases showed that the isolates from the veterinary hospital originated from a common source. These isolates also had indistinguishable IS200 profiles. However, PFGE was more discriminatory than IS200 profiles. All the veterinary hospital isolates and one independent isolate had the same antimicrobial resistance pattern and had at least one plasmid in common. Localisation of antimicrobial resistance genes indicated that the veterinary hospital isolates had more than one plasmid carrying resistance genes and that the genes encoding sulphathiazole and trimethoprim resistance were not on these plasmids. Phage typing was ineffective as 22 of the 28 isolates were untypeable. In conclusion, the combination of different methods used for epidemiological studies suggested that a single strain of MDR S. Heidelberg was isolated from horses admitted to the hospital for 6 years and caused salmonellosis in susceptible horses within that period with no apparent correlation between the antimicrobials used and retention of its MDR phenotype.  相似文献   

Clinical examination of chinchillas, hedgehogs, prairie dogs, and sugar gliders.     

T L Lightfoot 《Veterinary Clinics of North America: Exotic Animal Practice》1999,2(2):447-69, vii

Veterinarians in small animal practice are being presented with an ever-increasing number of exotic species. It has become critical that veterinarians expand their professional knowledge to include the basic procedures necessary for the proper diagnosis and therapy of these animals. Yet the husbandry, temperaments, physiology, and anatomy of many of these species make extrapolation from our well-developed techniques in dog and cat medicine inadequate. This article discusses some of the major species concerns and clinical findings of chinchillas, hedgehogs, prairie dogs, and sugar gliders presented to the veterinary practitioner. Practical techniques for evaluation of these animals with minimal stress (to the animal, the practitioner, and the client) and maximum efficiency are addressed.  相似文献   

Therapeutics of African pygmy hedgehogs and prairie dogs.     

T L Lightfoot 《Veterinary Clinics of North America: Exotic Animal Practice》2000,3(1):155-72, vii

The author examines the therapeutics for African pygmy hedgehogs and prairie dogs. The African or Asian hedgehog differs from the larger European hedgehog. Pronounced differences in size, seasonal behavior, and natural diet exist. Since the prairie dog's increase in popularity in the pet trade, numerous interrelated syndromes have been reported, including respiratory disease, obesity, cardiac disease, and oral neoplasia. This article describes the routes of administration and the common disease syndromes and appropriate therapeutics for each.  相似文献
