The effect of organic and inorganic sources of selenium (Se) on measures of Se status of mares and their foals, Se concentrations of colostrum and milk, and indices of immune function of foals was studied. Twenty late-gestation Standardbred mares were randomly assigned to one of two groups. All mare...

The effects of selenium (Se) supplementation and source on equine immune function have not been extensively studied. This study examined the effects of oral Se supplementation and Se source on aspects of innate and adaptive immunity in horses. Fifteen horses were assigned to 1 of 3 groups (5 horses/...

There is limited scientific information on relationships among smallholder dairy group membership duration, sustainable livelihoods, food and nutrition security in developing countries, and whether nutrition education of women dairy farmers enhances the nutritional benefits of being a dairy group me...

In two trials, Arctic char (Salvelinus alpinus) semen was frozen in 0.5 mL straws using extenders consisting of 0.3 M glucose and 10%, 12.5% or 15% methanol. Cryopreserved semen was thawed by immersing straws in 25°C water for 17 s (11.6°C s-1) or in 5°C water for 60 s (3.3°C s-1). The viability...

The N degradability and N digestibility of raw, roasted or extruded oilseeds were studied using an in vitro enzyme method. The N degradability and N digestibility of canola, linseed and soybean were calculated based on the proportional difference in N remaining after incubation and the initial N con...

Fortification of plants with selenium (Se) has been used to increase the Se intake of humans and farm animals but its use for correction of Se deficiency in horses has received little attention. The aims of this study were to evaluate the effect of Se-enriched fertilizer application on the Se concen...

The total fatty acid composition of rainbow trout (Oncorhynchus mykiss) spermatozoa and seminal plasma was investigated in fresh and in stored semen using gas liquid chromatography. Triglycerides, phospholipids, and cholesterol were measured and the effect of fatty acids, triglycerides, and choleste...

Seminal plasma protein of Arctic char Salvelinus alpinus was. characterized using sodium dodecyl sulfate (SDS) gel electrophoresis. Twelve protein bands with molecular weights of 7.2, 12.4, 15.3, 20.0, 20.4, 22.6, 39.4, 66.3, 74.0, 92.0, 94.5, and 130.1 kilodaltons (kDa) were detected. The effect of...

Lower fertility of preserved stallion semen may be caused by damage to the spermatozoa or premature capacitation during storage. We investigated the use of the flavonoid, quercetin, with a standard skim milk extender for storage of stallion spermatozoa to prevent premature capacitation and acrosome ...

The objective was to determine the oxidative stability of Arctic char (Salvelinus alpinus) semen following dietary supplementation with lowbush blueberry (Vaccinium angustifolium) product, alpha-tocopherol, alpha-tocopherol+blueberry product, or alpha-tocopherol+astaxanthin. Sperm lipid peroxidation...

The lipoprotein and lipid composition of the serum in postabsorptive haddock was characterized. A low level of very low density lipoproteins (VLDL; <50 mg/dl) was observed in serum. High density lipoprotein (HDL) was the predominant lipoprotein class followed by low density lipoproteins (LDL). Of...

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...

The effects of extender composition and freezing rate on motility and fertility of frozen-thawed Arctic char, Salvelinus alpinus, spermatozoa were investigated. Three freezing rates, two semen diluents and three cryoprotectants were tested. Semen frozen in 0.3 mol L-1 glucose diluent with 10% methan...

Mussel aquaculture on Prince Edward Island (PEI), Canada, is an important but relatively new industry. Although seed manipulation using hatcheries for mussel culture occurs on the west coast of North America, seed supply on the east coast of Canada, including Prince Edward Island (PEI), is based sol...

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...

Effects of processing whole soyabean on growth characteristics, fatty acid composition and lipid peroxidation activity of beef tissue were investigated with 40 crossbred steers. The basal diet consisted of grass and corn silage, barley grain, vitamins and minerals. The dietary treatments were: raw s...

Bulk tank milk selenium (Se) concentration was compared with mean serum Se concentration in 15 herds and was found to be an accurate reflection of the herd Se status. The Se status of 109 Prince Edward Island (PEI) dairy herds was monitored for 1 year using bulk tank milk Se concentration. Fifty-nin...

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...
