摘要: Two experiments were conducted to investigate the effects of reducing dietary crude protein on growth performance, odor gas emission from manure and blood urea nitrogen IGF-1 concentrations serum in nursery pigs. In experiment 1, treatments (i) CON (CP 19.5%) (ii) T1 16.0%). feces samples, NH3, H2S, acetic acid butyric emissions during treatment lower than (P < 0.05). feces-urine NH3 was 2, 28 crossbred (Landrace × Yorkshire × Duroc) pigs (13.58 ± 0.10 kg) used for a 42-day trial. Throughout entire experimental period, ADG ADFI higher On day 14, N digestibility fed diet that On days 42, DM greater dat BUN concentration conclusion, these results indicate reduction CP decreased H2S VFA performance
