Se bioavailability in commercial pet foods has been shown to be highly variable. The aim of the present study was to identify dietary factors associated with in vitro accessibility of Se (Se Aiv) in pet foods. Se Aiv is defined as the percentage of Se from the diet that is potentially available for absorption after in vitro digestion. Sixty-two diets (dog, n 52; cat, n 10) were in vitro enzymat...

Supplementing dairy cow diets with oilseed preparations has been shown to replace milk saturated fatty acids (SFA) with mono- and/or polyunsaturated fatty acids (MUFA, PUFA), which may reduce risk factors associated with cardio-metabolic diseases in humans consuming milk and dairy products. Previous studies demonstrating this are largely detailed, highly controlled experiments involving small n...

Dietary starch is required for a dry, extruded kibble; the most common diet type for domesticated felines in North America. However, the amount and source of dietary starch may affect digestibility and metabolism of other macronutrients. The objectives of this study were to evaluate the effects of 3 commercial cat diets on in vivo and in vitro energy and macronutrient digestibility, and to anal...

The digestive tolerance of three commercial diets (Baby Dog Small & Toy, Baby Dog Large & Medium, and Junior Dog Special Large) issued from a new high proteinlow carbohydrate diet range, Veterinary HPMTM, was assessed in growing dogs through an online survey administered to 129 pet owners over a 28-day testing period, and was compared to that of the dogs’ usual diets. Multiple-choice questionna...

Dietary fat saturation has been shown to affect hepatic apoB/E receptor expression and to modify low density lipoprotein (LDL) composition and density in guinea pigs. The current studies were designed to investigate the independent and interactive effects of dietary fat saturation alterations in apoB/E receptor expression and LDL composition on in vivo LDL turnover kinetics, both receptor-media...

Commercial high-yielding corn hybrids have not been evaluated for their ability to pigment egg yolk. Therefore, the objective of this research was investigate effects commercial with different carotenoid profiles as only source pigments in diets hens on yolk color and content, well deposition efficiency into Treatment diets, differing one five hybrids, were offered a completely randomized desig...

Several strategies are being developed to minimize nitrogen (N) pollution from poultry waste in areas with high concentrations of commercial poultry operations. This study focus on the effect of feeding reduced protein (CP) diets on laying hens housed under commercial conditions. The experiment was carried out using 144 Hy-Line W-36 hens which were randomly assigned to one of four dietary treat...

digestibility in broiler chickens fed on corn-soybean meal based diets. the experimental diets consisted of 1.corn-soybean meal based control diet 2. control diet supplemented with pectinas, 3. control diet supplemented with cellulase, 4. control diet supplemented with pectinase + cellulose, 5. control diet supplemented with pectinase + hemicellulase and 6. control diet supplemented with pectin...

Diabetic male wistar rats (n=32) were fed diets supplemented with 1% bitter yam steroidal sapogenin extract or commercial diosgenin for three weeks. Thiobarbituric acid reactive substances (TBARS), conjugated dienes, lipid profile and the activities of alanine and aspartate transaminases and acid phosphatase were measured in the liver. Diabetic rats (groups B-D) lost weight significantly (p<0.0...
