Human-animal interactions     

P H Hemsworth  J L Barnett 《Veterinary Clinics of North America: Food Animal Practice》1987,3(2):339-356

The objective of this article is to discuss the human-animal relationship in animal production, emphasizing the importance of this relationship to the productivity and welfare of the animal, some of the factors that may regulate the relationship, and how to manipulate this relationship to improve the productivity and welfare of the animal.  相似文献

Relationships between fear of humans, productivity and cage position of laying hens     

P H Hemsworth  J L Barnett 《British poultry science》1989,30(3):505-518

1. The productivity and behavioural responses of laying hens to humans were examined in relation to the effects of tier, row and position of the cage along the row over three consecutive 4-week periods. 2. Birds from the top tier had lower hen-day production, lower egg mass output and poorer efficiency of food utilisation than birds from the bottom tier in the third period. 3. Birds from the top tier showed greater avoidance of an approaching experimenter when in their cage or when on a table. 4. The production variables were significantly correlated with a number of behavioural responses to humans and a novel object, and with the corticosteroid response to handling/blood sampling. 5. The data suggest that birds from the top tier were more fearful of humans and that this higher level of fear may have been responsible for their lower productivity.  相似文献   

Congenital keratoconjunctivitis sicca and ichthyosiform dermatosis in the cavalier King Charles spaniel     

Barnett KC 《The Journal of small animal practice》2006,47(9):524-528

OBJECTIVES: To record a previously unreported congenital and hereditary condition affecting the eyes and skin in the cavalier King Charles spaniel. METHODS: Nineteen cases (13 litters) were investigated, with particular reference to eye and skin clinical signs. In addition, five generation pedigrees were obtained and studied from all cases with the exception of one. RESULTS: The eye signs were due to keratoconjunctivitis sicca, a common ocular disease in the dog, but rarely of congenital origin. The skin signs were of an ichthyosiform dermatosis; ichthyosis being a rare skin disease in the dog. In human beings, ichthyosis is a similar disease, mainly inherited and with a neonatal onset, and sometimes accompanied by other developmental defects. In the cavalier King Charles spaniel, the coat abnormality was noted at birth by the breeders as a 'curly coat', with deterioration of the skin signs as the animal became adult. CLINICAL SIGNIFICANCE: These two conditions occurring together in this breed is well recognised by some breeders but rarely by the veterinary profession. Successful treatment is not possible, although some improvement, particularly of the keratoconjunctivitis sicca, can be obtained. The probable hereditary nature of the condition is an important factor for control.  相似文献   

Immune responses to commercial equine vaccines against equine herpesvirus-1, equine influenza virus, eastern equine encephalomyelitis, and tetanus     

Holmes MA  Townsend HG  Kohler AK  Hussey S  Breathnach C  Barnett C  Holland R  Lunn DP 《Veterinary immunology and immunopathology》2006,111(1-2):67-80

Horses are commonly vaccinated to protect against pathogens which are responsible for diseases which are endemic within the general horse population, such as equine influenza virus (EIV) and equine herpesvirus-1 (EHV-1), and against a variety of diseases which are less common but which lead to greater morbidity and mortality, such as eastern equine encephalomyelitis virus (EEE) and tetanus. This study consisted of two trials which investigated the antigenicity of commercially available vaccines licensed in the USA to protect against EIV, EHV-1 respiratory disease, EHV-1 abortion, EEE and tetanus in horses. Trial I was conducted to compare serological responses to vaccines produced by three manufacturers against EIV, EHV-1 (respiratory disease), EEE, and tetanus given as multivalent preparations or as multiple vaccine courses. Trial II compared vaccines from two manufacturers licensed to protect against EHV-1 abortion, and measured EHV-1-specific interferon-gamma (IFN-gamma) mRNA production in addition to serological evidence of antigenicity. In Trial I significant differences were found between the antigenicity of different commercial vaccines that should be considered in product selection. It was difficult to identify vaccines that generate significant immune responses to respiratory viruses. The most dramatic differences in vaccine performance occurred in the case of the tetanus antigen. In Trial II both vaccines generated significant antibody responses and showed evidence of EHV-1-specific IFN-gamma mRNA responses. Overall there were wide variations in vaccine response, and the vaccines with the best responses were not produced by a single manufacturer. Differences in vaccine performance may have resulted from differences in antigen load and adjuvant formulation.  相似文献   

Cataract in the UK Leonberger population     

Heinrich CL  Lakhani KH  Featherstone HJ  Barnett KC 《Veterinary ophthalmology》2006,9(5):350-356

OBJECTIVE: To survey the Leonberger, a numerically small breed in the UK, for the presence of cataract and find statistical support for the possible presence of inherited forms of cataract. METHODS: Ocular examinations were carried out by the first author between September 1996 and September 1998 on 211 Leonbergers; results of the ocular examination of further 228 Leonbergers examined between January 1990 and September 1998 by members of the British Veterinary Association/KC/ISDS eye scheme (BVA/KC/ISDS eye scheme) panel were analyzed. Data from all dogs examined were pooled in a composite database of 365 Leonbergers and the relationships between offspring and parents for the identified forms of cataract were examined with appropriate statistical methods. RESULTS: Cataracts were diagnosed in 90 Leonbergers, the majority being nuclear (40) or posterior polar subcapsular (31). A subgroup of nuclear cataracts, diagnosed in 11 dogs, is described and named as 'posterior nuclear cataract.' For posterior polar cataract, a positive association between offspring and parents was made in the logistic regression model, supporting the suggestion of inheritance. CONCLUSIONS: The presence of several types of cataract in the UK Leonberger population is described. Statistical support for the inheritance of posterior polar subcapsular cataract is given.  相似文献
