The objective of the study was to determine growth performance, carcass characteristics and fatty acid composition of pigs fed on graded levels of Vachellia tortilis leaf meal (VTLM) diets. Forty-eight male Large White × Landrace finishing pigs with a mean (±standard deviation) body weight of 63.6 ± 0.73 kg (mean ± SD) aged 14 weeks were used. Pigs were allocated to individual pens in a completely randomized design and were assigned to six experimental diets containing 0, 30, 60, 90, 120, and 150 g/kg dry matter of VTLM. Each diet was offered ad libitum with fresh water to eight pigs in individual pens. There was a linear increase (P< 0.05) in ADFI and a linear decrease (P<0.05) in ADG and G: F with increase inclusion levels of VTLM. There was a quadratic response (P < 0.05) in intramuscular fat with increasing levels of VTLM. The inclusion of VTLM linearly (P < 0.05) decreased slaughter weight, warm carcass weight, cold carcass weight, cooler shrink and back-fat thickness. Total saturated fatty acids (TSFA) and total n-6 polyunsaturated fatty acids (PUFA) decreased linearly (P <0.001) with increasing levels of VTLM. There was a quadratic increase (P <0.001) in monounsaturated fatty acids (MUFA), total PUFA and total n-3 PUFA with increase inclusion of VTLM diet. The inclusion of VTLM reduced the total SFA and total n-6 PUFA while increasing the proportion of total MUFA and n-3 PUFA of pork. The optimum MUFA and total n-3 fatty were obtained at approximately 70 g/kg DM of V. tortilis leaf meal inclusion level.

这项研究的目的是确定以渐变圆叶锦粉日粮（VTLM）饲喂的猪的生长性能，car体特征和脂肪酸组成。使用四十八头雄性大白×长白育成猪，其平均体重（±标准偏差）为63.6±0.73kg（均值±SD），龄14周。猪以完全随机的设计分配给各只猪圈，并分配给六种实验饲料，分别含有0、30、60、90、120和150 g / kg干物质的VTLM。每种饮食都随意给八只猪圈养新鲜的水，每只圈养猪。ADFI呈线性增加（P <0.05），线性下降（PADG和G：F中<0.05），且VTLM的夹杂物含量增加。随着VTLM水平的增加，肌内脂肪发生二次反应（P <0.05）。线性添加VTLM（P <0.05）可以降低屠宰体重，warm体重量，冷weight体重量，冷缩和后脂肪厚度。随着VTLM含量的增加，总饱和脂肪酸（TSFA）和总n-6多不饱和脂肪酸（PUFA）呈线性下降（P <0.001）。呈二次方增长（P单不饱和脂肪酸（MUFA），总PUFA和总n-3 PUFA中的<0.001）随VTLM饮食的增加而增加。VTLM的加入降低了猪肉的总SFA和总n-6 PUFA，同时增加了猪肉的总MUFA和n-3 PUFA。最佳MUFA和总n-3脂肪含量约为70 g / kg DM玉米粉虱叶粉含量。
