This study evaluated the effect of conventional and sequential feeding programs with diets varying in amino acid content over the day on nutrient balance for growing-finishing pig. Sixty-eight barrows with an average initial BW of 25.0±2.04 were housed in a single pen with five automatic intelligent precision feeders (AIPF; University of Lleida, Ll...

Exercise-induced muscle damage and subsequent inflammation and soreness are frequently studied topics in both human and animal trials. Gait analysis using a commercial mat system is a newer technology that identifies the temporal and spatial qualities of a subject’s gait. Gait analysis in healthy canines, especially in an exercise model, has been i...

Future climate predictions suggest greater precipitation events and an increase in mean ambient temperature during winter months, creating wet and muddy conditions during the last third of gestation for spring calving beef cows. Cows housed in these conditions will likely have increased energy requirements; however, there is limited data on cow req...

In recent years, for economical purposes and to improve well-being conditions of cows, several dairy producers have adopted litter made from recycled manure solids (RMS). However, its use raises several safety issues, particularly with respect to mastitis and other infections. We previously observed cases of mastitis caused by K. pneumoniae and K. ...

Retained energy (RE) and energetic efficiency index were measured in Nellore bulls from divergent classes of residual feed intake (RFI). Thirty-four Nellore bulls (15 low RFI-LRFI and 19 high RFI-HRFI) were feedlot finished and slaughtered with 385 ± 40 kg of body weight (BW) and 520 ± 26.2 days of age. At the beginning of the experiment, five LRFI...

Objectives were to evaluate breed, heterosis (HI), and maternal effects on wool production in Rambouillet (R x R), Targhee (T x T), and reciprocal-cross (R x T and T x R) 1-yr-old ewes. Greasy fleece weights (GFW) were obtained at shearing and mid-side, britch, and whole-fleece core wool samples were collected to quantify average (A-FD) and CV of f...

In Canada, new forage varieties need not undergo grazing trials before registration and sale. As such, little is known about forage performance under grazing, or how animal preference and temperament affect grazing behaviour. To determine these effects, 6 cool-season forage species including meadow bromegrass (Bromus bieberseinii), orchardgrass (Da...

Bos taurus indicus cattle have superior ability for regulation of body temperature during heat stress due to a number of physiological and cellular level adaptive traits. The objectives of this study were to quantify the change in body temperature in heifers with various proportions of Brahman genes per unit increase in heat stress as measured by T...

An Animal Science degree prepares students for a broad range of career opportunities yet the two most discussed in the literature and assumed by society are in animal science industry or veterinary medicine. However, studies indicate that -60% of our students enter into education as a career path, yet animal science departments typically do not emp...

Target protein mass at maturity is a common “attractor” used in animal models to derive components of animal growth. This target muscle protein at maturity, M*, is used as a driver of a model of animal growth and body composition with pools representing muscle and visceral protein; where viscera is heart, lungs, liver, kidneys, reticulorumen and ga...
