The effects of colostrum consumption and feed restriction during marketing and transportation in the recovery of dairy beef male Holstein calves

The aim of this study was to evaluate the effects colostrum consumption and feed restriction on biomarkers stress, nutritional health status, gut functionality, behavior in male dairy beef calves being marketed transported. A total 82 Holstein [42 ± 1.2 kg body weight 14 0.9 d age] were used amount given at birth farm origin, degree suffered an assembly center simulation (d −4 −1), a 19 h transportation −1). Treatments as follows: control (CTRL; n = 16) fed 10 L milk replacer (MR) concentrate center, not transported; high colostrum-milk (HCMR; 17) MR colostrum-rehydrating solution (HCRS; rehydrating (RS) low (LCMR; 17), 2 (LCRS; RS Transported mimic long transportation. After transport, all 2.5 twice daily had ad libitum access concentrate, straw, water. Calves' recovery followed during 7 d. Concentrate intake records collected from until BW blood samples - 4, 1, 0, 2, study. Results showed that feeding regimen provided reduced for HCRS LCRS compared with CTRL, HCMR, LCMR calves. peaked 0 transported by drop 1 after lower On −1, nonesterified fatty acids β-hydroxybutyrate concentrations greater transportation, serum Cr-EDTA concentration than LCMR, CTRL lowest citrulline. Finally, scores 7. In summary, both greatest negatively affected BW, arrival rearing farm.
