Effect of alternative, individual and group housing systems, and management factors in group pens on the well-being of gestating sows
Animal well-being has become one of the most controversial issues associated with modern animal agriculture. How animals raised for human consumption are being housed in modern housing systems has resulted in the passing of referendum that ban gestation stalls for sows, crates for veal calves, and …

Investigating the effect of dexamethasone on productivity, immune function, and behavior in dystocic periparturient dairy cattle
… to the increased tissue trauma and stress the animal endures during the lengthened parturition. To decrease the increased inflammatory response seen in dystocic animals and improve their well-being in the postpartum period, we administered either a potent steroid, dexamethasone (DEX), or a …

An investigation of laying hen interactions with ammoniated environments by means of preference testing
… production performance and, in extreme cases, animal survival. Thus, controlling the environment in commercial livestock and poultry facilities is important for improving animal welfare and optimal production, as well as for the health and safety of the workers within the barns. Delineation of …

An investigation of social structure in housed dairy cows
… with corresponding impacts on yield and animal well-being. Social behaviour may provide a useful indicator of normal animal activity, and subsequent changes with health status, particularly if automatically monitored to reduce labour. This thesis applies a local positioning system (LPS) …

Effects of Supplementing Crystalline L-Valine and L-Isoleucine and a Novel Threonine Biomass in Reduced Crude Protein Diets fed to Broilers
… growth performance, processing yields, or animal well-being. A common approach is to reduce dietary crude protein (CP), the second most expensive component in a broiler diet. Subsequently, reducing CP will reduce the inclusion levels of intact protein sources (e.g., soybean meal [SBM]), …

The effects of stocking density and housing on feed efficiency and growth performance of broiler chickens
… density and housing type significantly impact animal well-being and performance. The economic implications of stocking density and housing type are complex, requiring a careful equilibrium to maximize production costs, revenue, and total profitability in broiler chicken farming. Ethical …
