ABSTRACT The objective of this study was to evaluate passive immunity transfer, health, performance, and metabolism of Holstein calves fed colostrum supplement associated with medium-quality colostrum. After birth, calves were blocked according to birth weight and date and distributed into the following treatments: high-quality colostrum (> 50 mg of Ig/mL; n = 15; 150 g kg−1 BW; positive control group); medium-quality colostrum (30-40 mg of Ig/mL; n = 14; 150 g kg−1 BW), and medium-quality colostrum (30-40 mg of Ig/mL; […]

The effect of yolks from birds hipperimmunized birds against Escherichia coli (E. coli) pathogenic for swine on the passive immunity of newborn piglets in a producer unit of piglets was studied. It was evaluated ELISA optical density (OD) of antibodies against E. coli, body weight and the frequency of diarrhea (FcD) in 137 newborn piglets born from 25 primiparous gilts non-vaccinated against E. coli. The gilts were considered blocks. From each gilt, six piglets from both sexes were separated, excluded […]
