204 Effects of Feeding Cellutein to Pigs at Various Concentrations from Weaning Through Finishing

Abstract

Abstract The study objective was to evaluate the effects of celluTEIN (CT) on growth performance and feed efficiency during nursery and grow-finish phases. Barrows (n = 96; average BW 7.5 kg) were assigned to 32 pens with 3 pigs per pen. Pens were randomly assigned to one of four treatments: 0 ppm CT throughout (CON), 175 ppm CT during the nursery (TRT2), 100 ppm CT during grow-finish (TRT3), and 175 ppm CT during nursery and 100 ppm CT during grow-finish (TRT4) phases. The nursery phase consisted of trial day 0 to 42 and grow-finish was trial day 43 to 119. There were no treatment effects on d 0 BW and nursery feed consumption (FC; P > 0.05), but there were effects on d 42 BW, and nursery average daily gain (ADG), and feed conversion ratio (FCR; P < 0.05). Pigs in TRT2 and 4 did not differ ( P> 0.05) in BW, ADG, and FCR, but had greater measures than pigs in the other two treatments (P < 0.05). Treatment affected all measures in the grow-finish phase (P < 0.05). Control pig d 119 BW was less than all other treatment pigs (P < 0.05), TRT4 pigs had greater BW than TRT2 and 3 (P < 0.05), who did not differ (P > 0.05). All treatments had different ADG, with TRT4 being the greatest followed by TRT3, TRT2, and CON (P < 0.05). Pigs in TRT4 had greater FC than pigs in all other treatments (P < 0.05), who did not differ (P > 0.05). Control pigs had greater FCR than pigs in all other treatments (P < 0.05), who did not differ (P > 0.05). Throughout the entire 119-day study, treatment affected all measures (P < 0.05), except FC (P > 0.05). Control pig ADG was less than all other treatment pigs (P < 0.05), TRT4 pigs had greater ADG than TRT3 and 4 (P < 0.05), who did not differ (P > 0.05). All treatments had different FCR, with TRT4 being was the least followed by TRT3, TRT2, and CON (P < 0.05). These data illustrate pig performance improved when CT was supplemented in either the nursery or the finisher. The greatest feed efficiency and gain benefit was observed when CT was supplemented during both phases.
