Dietary-induced negative energy balance has minimal effects on innate immunity during a Streptococcus uberis mastitis challenge in dairy cows during midlactation

Ten multiparous Holstein cows were used to determine the effects of negative energy balance (NEB) on the immune response to a Streptococcus uberis (strain O140J) mastitis challenge during midlactation. Before the study, milk from all quarters of each cow was bacteriologically negative, with a compos...
