Effect of spray-dried porcine plasma protein on feed intake, growth rate, and efficiency of gain in mice.
One hundred eight mice were weaned at 21 +/- 1 d and allotted to four dietary treatments: 1) control, 2) control + 4% spray-dried porcine plasma protein (SDPP), 3) control + 8% SDPP, and 4) control + 12% SDPP. Daily gain for males increased with increasing SDPP during wk 1 (P < .01), wk 2 (P < .01), and for the entire 3 wk (P < .01). Daily gain increased quadratically with increasing SDPP for females during wk 1 (P < .05). During the 3rd wk, ADG decreased for females with increasing SDPP (P < .05). Daily feed intake increased linearly (P < .01) with increasing SDPP in all periods. Gain-to-feed ratio (G/F) increased with increasing SDPP during wk 1 (P < .01) and for the first 2 wk (P < .05). During wk 3, G/F decreased with increasing SDPP level (P < .01). Gain-to-feed ratio of females responded quadratically to increasing SDPP during wk 1 (P < .05), whereas G/F of males increased linearly with increasing SDPP level. Gain-to-feed ratio for the entire trial was unaffected by treatment among females (P = .82) but increased linearly with increasing SDPP levels among males (P < .01). Liver weight increased quadratically with increasing SDPP levels for males (P < .05) and females (P < .05). Treatment effect on liver weight per kilogram BW.75 approached significance (P < .10) in females. Male liver weight/100 g BW and liver weight per kilogram BW.75 responded quadratically to increasing SDPP levels (P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)
