Social Behavior and Productive and Stress Parameters in Holstein Steers Fattened in Three Contrasting Production Systems

Abstract

Beef production with Holstein male calves is becoming more intensive in Uruguay. Some of the new systems with confined animals could improve productivity but also could compromise animal welfare. The aim of this study was to compare animal welfare, stress evidence and productivity of castrated young males reared in three different productive systems. The traditional pastoral system (T3) was compared with, a confined fattening system (T1) and an alternative one with confinement and six hours diary access to pastures (T2). The experiment was performed for evaluating the first phase of fattening period (initial mean live weight 93±20.3 kg; and 112±11 days of age). No differences (p = 0.1254) between treatments were detected for live weight gain 0.756±0.829, 0.757±0.676 and 0.730±0.762 kg day -1 for T1, T2 and T3, respectively. There was no evidences of increasing stress or health problems in any production system, according to the obtained serum profile of enzymes and hormones, however permanent confined animals increased agonistic behavior, which could reflect some welfare problems that might increase in the following phases of the fattening process.

Effect of transportation distance and lairage time on selected behaviors and carcass parameters in zebu cattle—a study using the animal focal sampling method

“…Pushing behavior was more observed in animals transported over long distances. Hypothetically, this could be explained by the fact that animals transported over long distances arrived more exhausted at the slaughterhouse, performing behaviors that demand less energy, such as pushing other animals to moving them away, instead of head-butting to promote this action ( 31 ).…”

A Scoping Review: The Impact of Housing Systems and Environmental Features on Beef Cattle Welfare

“…Studies examining feedlot housed cattle observed that cattle in feedlots engaged in agonistic behaviors more frequently and for longer durations (e.g., headbutting, pushing, displacement) [19] compared to cattle with access to pasture. Similarly, feedlot-housed cattle spent more time standing and walking, as well as engaged in lying for a shorter duration of time paralleled to cattle housed in a hoop barn [18].…”
