An international comparison of pig breeds using a common control stock

In order to compare the genetic merit of different pig stocks a co-operative experiment was carried out in seven different countries. A group of Norwegian Landrace pigs was used as a control population and divided at random into seven samples, one sample being sent to Northern Ireland, the Republic of Ireland, the Federal Republic of Germany, Finland, The Netherlands and Great Britain and one retained in Norway. The sample pigs were used as breeding stock and comparisons made of their progeny in each country, the tests being carried out either in national testing stations or in experimental stations alongside comparable animals from that country. The pigs were fed according to standards prevailing in each country and were slaughtered and measured according to local methods.The results have been used to compare local breeds with the control stock in a great number of performance characteristics. For most traits, the differences between breeds were not found to be large. In general, pigs from the control population of Norwegian Landrace had good growth rates and efficiency of food conversion, and produced carcasses that were long, low in backfat and showed good muscle quality, but were rather poor in area of “eye” muscle and in ham shape. The control population of Norwegian Landrace also differed in performance from that of pigs submitted to Norwegian testing stations and the possible reasons for this and the general problem of making indirect comparisons between countries are discussed.  相似文献   

The demonstration of maedi/visna virus in sheep in Great Britain.     

M Dawson  D Chasey  A A King  M J Flowers  R H Day  M H Lucas  D H Roberts 《The Veterinary record》1979,105(10):220-223

A virus indistinguishable from that causing maedi/visna has been isolated from a sheep flock in Great Britain. The virus was identified in cell cultures using immunofluorescent and electron microscopical techniques. The complement fixation test and the agar gel immunodiffusion test were used to assess the proportion of serological reactors within the flock. There has been no evidence of clinical disease in the flock into which foreign imports were introduced in the years prior to 1976.  相似文献   

Pet health insurances and contract services: the potential for practice involvement.     

N King  J Gripper  E W Hallam  S L Foster  J W Walsby  S D Gunn  D Carter 《The Veterinary record》1979,104(22):494-495

Pet medical insurance has appreciable advantages and the existing policies appear to provide a beneficial service. But administrative costs of the small premiums involved make it of doubtful commercial attraction or benefit to the client. However, practice contract service schemes reduce administrative costs and can provide many of the advantages of insurance. Such a scheme is described. A coordinating agency outside the practice to produce promotional material, contracts, formulae for setting premiums and exclusions and to act as an arbitration agency for disputes could be established given the demand.  相似文献   

Canine Rocky Mountain spotted fever: a kennel epizootic   总被引：2，自引：0，他引：2

Within a period of 5 consecutive days after the initial observation of illness was made, 7 of 12 Siberian Husky dogs developed clinical signs of Rickettsia rickettsii infection. One dog died and was necropsied. Clinical signs of infection consisted of lethargy, anorexia, ocular and nasal discharges, and neurologic disorder (incoordination and rolling). Scleral blood vessel injection, fever, lymphadenomegaly, splenomegaly, and increased bronchovesicular lung sounds were prominent findings. Clinical laboratory test results identified decreased platelet numbers, variable neutrophil counts, increased serum alkaline phosphatase activity, hyponatremia, hypokalemia, and bilirubinuria. Diagnosis of Rocky Mountain spotted fever was confirmed by serologic evaluation of acute and convalescent sera, using the micro-immunofluorescence technique, and R rickettsii antigen was determined by demonstration of intracellular rickettsial organisms in vascular endothelial cells of brain and lung (stained with carbol-basic fuchsin and aqueous malachite green) and by demonstration of spotted fever-group rickettsiae in tissues by direct fluorescent antibody technique. Near-simultaneous naturally occurring tick-borne infection of 7 dogs with R rickettsii documents an unreported occurrence.  相似文献   

Antibodies to selected canine pathogens and infestation with intestinal helminths in golden jackals (Canis aureus) in Israel.     

M Shamir  B Yakobson  G Baneth  R King  S Dar-Verker  A Markovics  I Aroch 《Veterinary journal (London, England : 1997)》2001,162(1):66-72

Blood and fecal samples, collected from 46 healthy adult free-ranging golden jackals captured in two different locations in Israel, were examined. A serological Study was conducted to investigate the prevalence of circulating antibodies reacting with four common canine pathogens: canine distemper virus (CDV), canine parvovirus (CPV), Ehrlichia canis and Leishmania infantum. Faecal flotation and haematological tests were also performed. The seroprevalence of CPV, E. canis, CDV, and L. infantum were 72.3% (34/47), 54.3% (25/46), 52.2% (24/46), and 6.5% (3/46) respectively. Faecal flotation tests revealed a high prevalence of Ancylostoma caninum (13/17, 76%) and a low prevalence of Dipilidium caninum infestation. Examination of blood smears revealed Hepatazoon canis gamonts in one jackal. Golden jackals are among the most common free-ranging carnivores in Israel and neighboring countries. Their habitats are in proximity to densely populated areas and they bear close phylogenic relation to the domestic dog. These facts, combined with the high prevalence of the jackals' exposure to the major canine pathogens demonstrated in this study, suggest that they may serve as a reservoir for the transmission of certain diseases to domestic dogs.  相似文献   

Moldy corn in diets of gestating and lactating swine   总被引：1，自引：0，他引：1  

L G Young  G J King  L McGirr  J C Sutton 《Journal of animal science》1982,54(5):976-982

Moldy corn was substituted for normal corn in four dietary treatments to provide 0, 2.1, 3.7 and 4.8 ppm of zearalenone. The diets were fed to gilts from the day after first observed estrus through two gestation-lactation periods. Each diets was fed to 11 gifts initially. Overall reproductive performance appeared to decrease as the level of moldly corn in the diet increased, with fewer sows completing two parities and fewer piglets weaned per litter, especially from sows fed the highest level of moldy corn. Three-week-old gilts that nursed sows fed the highest level of moldy corn had increased weight of reproductive tracts. In 35-d-old gilts, symptoms of estrogenism increased as the level of moldy corn in the diet increased, even though there were no symptoms of estrogenism in the mature gilts or sows fed the same diets. Neither zearalenone nor its metabolites (alpha- and beta-zearalenol) were detected in milk obtained 1 or 14 d postpartum.  相似文献   

Unusual phenomena during pregnancy in the cat and cow.          下载免费PDF全文

G J King  E C Amoroso 《Canadian journal of veterinary research》1983,47(3):379-381

Unusual situations were observed during examination of pregnant uteri from a cat and a cow. The feline specimen revealed three corpora lutea at the surface of each ovary with three fetuses developing normally in the left and two in the right uterine horn. The right horn had been ruptured between two of the locular enlargements but the damage was sealed by the omentum. Three conceptuses were present in the cow's uterus. Two of these embryos, each with its individual allantois, were developing within a single chorion within one uterine horn. The adjacent tips of these allantoic vesicles were entangled into a complex knot which could provide opportunity for vascular anastomosis.  相似文献
