Abstract:
Feedlot implants consistently increase growth, improve feed efficiency, and add carcass weight when aligned with genetics, dietary energy, and marketing endpoints. Across studies summarized in this article, average responses to implants are 10% to 30% greater average daily gain and 5% to 15% improved G:F, with the greatest biological response early in the payout period. Steers generally respond greater to implants than heifers; heifer responses are directionally similar but smaller. Coated (extended-release) implants lengthen payout and may reduce reimplant labor, whereas reimplant programs can capture higher peaks in gain but sometimes transiently depress dry matter intake.

01:09Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
