In North America, there are few representative data about the effects of management practices on equine welfare. In a randomized survey of 312 nonracing horses in Prince Edward Island (response rate 68.4%), owners completed a pretested questionnaire and a veterinarian examined each horse. Regression...

An equine abuse policy was developed as an adjunct to an equine management survey. If at least 3 of 5 categories caused concern, a report to the authorities was indicated. The policy was not used but, in the absence of other guidelines, it might assist veterinarians considering potential abuse cases...

A clear understanding of the role of different papillae in the pig may permit the development of a more palatable diet, thus, better utilizing anatomical structures and morphological characteristics to enhance health and productivity in this domestic species. The study used ten healthy market-size, ...

There are no detailed, representative, horse-level data about equine management practices in different parts of Canada. To help address this, the demographics, management, and welfare of 312 nonracing horses in Prince Edward Island were examined in a randomized, horse-level survey during summer 2002...

In this study, the amount of nursing synchronisation was quantified, the dependence of the degree of synchronisation on the spatial distance between sows was examined, and the effect of nursing vocalisation playback on nursing frequency and nursing synchronisation was assessed in a large commercial ...

Purpose: A recent genome-wide scan revealed a major susceptibility locus for idiopathic generalized epilepsies (IGEs) in the chromosomal region 8p12 in 32 IGE families without members with juvenile myoclonic epilepsy (JME). This study explored the presence of an IGE locus in the chromosomal region 8...

A recent genome-wide scan revealed suggestive evidence for two susceptibility loci for idiopathic generalized epilepsy (IGE) in the chromosomal regions 5p15 and 5q14–q22 in families with typical absence seizures. The present replication study tested the validity of the tentative IGE loci on chromo...

A previous study of 34 nuclear pedigrees segregating juvenile myoclonic epilepsy (JME) gave significant evidence of linkage with heterogeneity to marker loci on chromosome 15q13-14 close to the candidate gene CHRNA7 (Hum. Mol. Genet. 6 (1997) 1329). The aim of this work was to further evaluate the p...

A retrospective cross-sectional survey of dog-owning veterinary clients was undertaken in 1996 in three Canadian provinces (New Brunswick, Nova Scotia, and Prince Edward Island) to generate a population of dogs for future use in a more detailed survey on canine behaviour. The questionnaire was desig...

The objective of this study was to determine if using maternal sounds, at a higher frequency, associated with lactation, would indirectly influence milk production by the sow, thus increasing litter weight. The litters of 36 crossbred sows were allocated into 4 experimental groups. The study was div...

A detailed telephone survey of dog owners was undertaken in 1996 to determine the risk factors for biting behaviour of dogs in a household setting. Individuals were selected from a cross-sectional population of veterinary clientele in the Canadian provinces of New Brunswick, Nova Scotia, and Prince ...

The characteristics of 227 biting dogs, their homes, and their victims were gathered in a detailed telephone survey of general veterinary clientele in the Canadian provinces of New Brunswick, Nova Scotia, and Prince Edward Island. All of the dogs had bitten either someone living in the same househol...

Genetic factors play a major role in the aetiology of idiopathic generalised epilepsies (IGEs). The present genome scan was designed to identify susceptibility loci that predispose to a spectrum of common IGE syndromes. Our collaborative study included 130 IGE-multiplex families ascertained through ...

Eight, pregnant, primiparous sows received i.v. infusions of TRH (5 micro g/kg; TRH group) or physiological saline (0.9% NaCl; control group) from day 105 of gestation until farrowing. The plasma concentrations of thyroxine and triiodothyronine increased in sows treated with TRH. There were no diffe...

Before suckling, 14 newborn piglets, weighing <1.25 kg, were dried, weighed, and their rectal temperatures recorded. Rectal temperatures were then reduced to 25 degrees C, to induce hypothermia, by placing the piglets in a 10 degrees C cooling unit. A microwave (MW) generator was programmed to re...

The survival rates of pigs subjected to different farrowing management protocols were compared. 60 litters of YorkxLandrace piglets were either unattended at farrowing or were dried, had the umbilical cord tied, had oral and nasal cavities suctioned to clear mucus, received oxygen and received bovin...

Twelve pregnant primiparous sows were catheterized on day 102 of gestation and randomly allocated to receive ACTH (days 112-113 of gestation [2d], days 105-parturition [10d]) or saline. At parturition the 3rd, 4th, 6th and 7th piglet born alive were sacrificed either at birth or at 6 h. The later gr...

Microwave radiation (2.45 GHz) was examined as a heat source for rewarming chilled neonatal piglets. A multi-mode cavity (60 x 60 x 60 cm) was constructed of 22 gauge perforated galvanized steel. The radiation applicator was a slotted waveguide, 70 cm in length, which was located centrally 46.5 cm a...
