The objective of this study was to determine the effects of deworming and protein supplementation during late-summer on performance of fall-born heifers grazing native warm-season pastures.
Anthelmintic treatment did not influence weight gain during the first period of the study (August) although deworming did increase performance in each of the last two periods (September and October).
Overall, the combination of anthelmintic treatment and protein supplementation increased average daily weight gain by 0.76 lb/d, with approximately 63% of the response being attributed to protein supplementation and 37% of the response being attributed to deworming.
