Treatment effects on growth performance factors, plasma ammonia content (µmol/L) and muscle proximate composition (%) of grass carp.

1Mean values of triplicate groups, with thirty fish in each group. And mean values within the same row with different superscripts are significantly different (P2Values are means ± SD (n = 6), and mean values within the same row with different superscripts are significantly different (PIBW: initial body weight (g/fish); FBW: final body weight (g/fish); PWG: percentage weight gain (%); SGR: specific growth rate (%/day); FI: feed intake (g/fish); FE: feed efficiency (%); PER: protein efficiency ratio; PAC: plasma ammonia content.weight gain (WG) = FBW (g)–IBW (g);PWG = 100×WG (g)/IBW (g);SGR = 100×[ln FBW (g)-ln IBW (g)]/number of days;FE = 100×weight gain (g)/feed intake (g);PER = wet weight gain (g)/protein intake (g).Treatment effects on growth performance factors, plasma ammonia content (µmol/L) and muscle proximate composition (%) of grass carp.

1. 三组重复组的平均值，每组包含30尾鱼。同行内带有不同上标的平均值具有显著差异（P < 0.05）。2. 数值以平均值±标准差表示（n = 6），同行内带有不同上标的平均值具有显著差异（P < 0.05）。相关术语定义如下：初始体重（initial body weight）：单位为g/尾，缩写IBW；末体重（final body weight）：单位为g/尾，缩写FBW；增重率（percentage weight gain）：单位为%，缩写PWG；特定生长率（specific growth rate）：单位为%/天，缩写SGR；摄食量（feed intake）：单位为g/尾，缩写FI；饲料效率（feed efficiency）：单位为%，缩写FE；蛋白质效率比（protein efficiency ratio），缩写PER；血浆氨含量（plasma ammonia content），缩写PAC。计算公式如下：增重（weight gain, WG）= 末体重（g） - 初始体重（g）；PWG = 100×WG（g）/IBW（g）；SGR = 100×[ln FBW（g） - ln IBW（g）]/养殖天数；FE = 100×增重（g）/摄食量（g）；PER = 湿重增重（g）/蛋白质摄入量（g）。本实验旨在探究不同处理对草鱼生长性能指标、血浆氨含量（单位：µmol/L）及肌肉常规营养成分（单位：%）的影响。
