Liver abscesses (LA) in feedlots are costly to the beef industry. At harvest, LA cause an increase in liver condemnations, carcass trimming, and a decrease in quality grade. The objective of this research was to develop an experimental LA model in Holstein steers using an acidotic diet with and without intraruminal inoculation of bacteria involved ...

The objective of this study was to determine the effects of pelleting on the standardized ileal digestibility (SID) of amino acids (AA) in diets with or without increased concentrations of free AA and reducing sugars (RS). Treatments were arranged in a 2 × 2 × 2 factorial with the main effects of diet form (mash or pellet), crystalline AA (low or h...

Pet and human populations continue to grow and compete for nutritious, sustainable protein sources. The incorporation of alternative proteins like torula yeast can provide a solution to this problem. Torula yeast also may have additional health benefits like reducing gut inflammation. To test its effects in dogs, we fed Labrador Retrievers with chr...

Improving resilience, i.e., the capacity to respond to the impacts of stressors and to effectively recover to normal status, is a promising approach to enhancing the well-being of pigs and the productivity of the pig industry. Animals with high resilience can maintain their performance under challenging conditions. However, obtaining heritable meas...

The reduction of methane (CH4) emissions and nitrogen (N) excretion from livestock production systems can help mitigate environmental impact and improve feeding efficiency. The energy requirements of livestock are crucial for enhancing their performance and minimizing environmental impact. It is imperative to accurately ascertain the N and energy e...

High plasma concentrations of insulin can cause acute laminitis. Ponies and horses with insulin dysregulation (ID) exhibit marked hyperinsulinaemia in response to dietary hydrolysable carbohydrates. Glucagon-like peptide-1 (GLP-1), an incretin hormone released from the gastrointestinal tract, enhances insulin release, and is increased post-prandial...

Concentration of volatile fatty acid (VFA) provides an imprecise view of VFA dynamics due to the confounding effects of fluid pool size and dynamics. Determination of VFA flux using isotope is expensive and a complex methodology. Therefore, a rapid and affordable approach to explore VFA dynamics may allow comprehensive characterization of VFA avail...

A mechanistic, dynamic model was developed to calculate body composition in growing lambs by calculating heat production (HP) internally from energy transactions within the body. The model has a fat pool (f) and three protein pools: visceral (v), non-visceral (m), and wool (w). Heat production is calculated as the sum of fasting heat production (FH...

The experiment objective was to evaluate the impact of xylanase over time on viscosity and digestibility in growing pigs fed corn-based fiber. Twenty gilts with an initial body weight of 30.6 ± 0.2 kg (n = 5 per dietary treatment) were fitted with t-cannulae in the medial jejunum and terminal ileum, housed individually, and randomly assigned to one...

Rumen inert fat (RIF) is a type of fat supplement that is used in the diets of beef cattle as early as 6 mo of age in calves and continues through the finishing period to improve the dietary energy density which can be used by the animal to deposit more lipid in the muscle tissue. However, for Hanwoo beef cattle, the precise time of RIF supplementa...
