2016 ACVIM Forum Research Abstract Program

AEA varies widely between calves even when feeding is standardized. There appears to be opportunities to improve the serum IgG concentration in calves by feeding increased volumes of colostrum, as in this study we were unable to saturate the absorption process. With the wide range of AEA values obtained, there may be opportunities to improve AEA through genetic selection. The objective of this study was to determine the disposition of chlortetracycline (CTC) in pregnant ewes and their unborn fetuses following oral administration of 500 mg/head/day during the last trimester of gestation.
