Abstract
This study evaluated a biopeptide that contained a blend of plant/yeast products, Ultimate Protein 1672 (UP 1672, Alltech, Inc., Nicholasville, KY), and was compared at 4 dietary replacement levels for blood plasma protein. Dietary blood plasma protein levels were set at 6.0, 3.0 and 0.0% for each of two periods. Dietary substitution was on the basis of lysine replacement. All pigs were fed a common diet during phase 3 or from the period from 24 to 38 day postweaning. Trials were conducted at Michigan State, Ohio State, and Purdue Universities. The study used a total of 344 pigs that were weaned at 14 to 21-day of age and averaged 12.3 lb body weight. During the 0 to 10-day period there was a decreased response (P < 0.01) in daily gain and feed intake as the dietary level of UP 1672 increased. Treatment responses, however, during the 10 to 24-day period were similar at each of the substitution levels of UP 1672. For the 24 to 38-day and 0 to 38-day periods no differences in daily gains, feed intake and feed efficiencies were observed. These results indicate that during the phase 1 period, pig performance was higher when plasma protein was fed, but for the 10 to 24-day period UP 1672 was as equally effective as plasma protein. For the overall 38-day period performance responses were similar for all treatment groups. Feed costs were somewhat lower when the UP 1672 product was fed. Our results suggest that UP 1672 could be effective when fed during phase 2 and could lower nursery diet costs.
