Autor: Thomas H. Welsh, L E Hulbert, J.W. Dailey, Rhonda C. Vann, Jeffery A. Carroll, Ronald D. Randel, Scott T. Willard, N.C. Burdick

Publikováno v: Livestock Science. 129:166-172

This study investigated whether temperament influences rectal temperature and serum concentrations of cortisol and epinephrine in response to transportation. Brahman bulls were selected based on temperament score (average of exit velocity, EV, and pe

Evaluation of drop versus trickle-feeding systems for crated or group-penned gestating sows

Autor: L E, Hulbert, J J, McGlone

Publikováno v: Journal of animal science. 84(4)

A total of 160 gilts were used to evaluate the effects of pen vs. crated housing systems and drop- vs. trickle-fed feeding systems on sow productivity, occurrence of lesions during farrowing and weaning, immune measures, and behavioral responses duri
