Interpretive Summary:

Technical Abstract: The objective was to investigate the effects of ground beef from cattle administered commercial growth promotants on puberty attainment and body composition in female swine. Twenty-four gilts were selected based on strict selection criteria to reduce piglet variation. Treatments were randomly assigned based on BW (24.5 +/- 3.2 kg) and litter number, and included daily feedings of a 113-g beef patty from non-implanted steers (NAT), a 113-g beef patty from steers receiving estrogenic implants (IMP), a 198-g piece of tofu (TOFU), or a negative control receiving no supplemental treatment (CON). All gilts received the very low estrogen base diet fed at approximately 3.5% of BW and adjusted weekly to account for intake. Gilts were slaughtered at the NDSU Meats Lab a minimum of 3 d following first visual heat. Data were analyzed using the PROC MIXED function of SAS, with litter as a random variable. No treatment effect was observed with any growth parameter (P >/= 0.32), measurement of puberty including age at first heat (P >/= 0.46), or carcass composition measurement (P >/= 0.35). These data indicate that consumption of beef from cattle receiving estrogenic growth promotants does not influence growth rate, body composition, or attainment of puberty.
