A total of 120 finishing pigs with an average initial body weight of 49.72 ± 0.08 kg (mean ± SD) were used in a 10 weeks trial. Pigs were randomly allotted into one of four dietary treatments (6 replicate pen/treatment, 5 pigs/pen). The nutritional dietary treatments were corn, soy bean meal, palm- kernel meal, and rapeseed meal based basal diets supplemented with 0, 0.05, 0.10, and 0.20% of Achyranthes japonica extract (AJE). Dietary inclusion of AJE supplementation had trend to increase the body weight and average daily gain of pigs at week 10 and the overall experimental period, respectively. The graded level of AJE supplement had increase the total track digestibility dry matter (p = 0.067) only at week 5 while nitrogen and energy digestibility (p < 0.05) was linearly increased at both weeks 5 and 10. During week 10, pigs fed with an increased level of AJE supplementation had linearly increase (p < 0.05) fecal Lactobacillus counts. In addition, AJE supplementation in the diet of finishing pigs had linearly decreased (p > 0.05) NH3 emission of gas and trend to decrease total mercaptans during week 10. Dietary inclusion of AJE supplement resulted in a linear increase in the blood protein concentration level. Moreover, drip loss was linearly reduced on day 5 and day 7 (p > 0.05) post slaughter in finishing pigs fed with gradually increased levels of AJE supplementation. During weeks 5 and 10, pigs fed with graded levels of AJE supplementation had linearly increase (p < 0.05) the backfat thickness and lean meat percentage. Therefore we conclude that dietary inclusion of AJE with palm kernel meal and rapeseed meal could be benificial to enhance the growth performance, nutrient digestibility, fecal microbial, blood prolife, meat quality and reduced fecal gas emission in finishing pigs.

牛膝提取物对饲喂含有棕榈仁粕和菜籽粕作为豆粕部分替代品的育肥猪生产性能的影响



在为期 10 周的试验中,总共使用了 120 头平均初始体重为 49.72 ± 0.08 kg(平均值 ±标准差)的育肥猪。猪被随机分配到四种饮食处理中的一种(6 个重复栏/处理,5 头猪/栏)。营养膳食治疗是以玉米、豆粕、棕榈仁粕和菜籽粕为基础的基础日粮辅以0%、0.05%、0.10%和0.20%的牛膝提取物(AJE)。日粮中添加 AJE 补充剂有分别在第 10 周和整个实验期间增加猪体重和平均日增重的趋势。 AJE 补充剂的分级水平仅在第 5 周增加了干物质的总消化率 ( p = 0.067),而氮和能量消化率 ( p < 0.05) 在第 5 周和第 10 周均线性增加。在第 10 周,猪饲喂AJE 补充水平的增加使粪便乳酸菌计数线性增加 ( p < 0.05 )。此外,在第 10 周期间,在育肥猪日粮中添加 AJE 可以线性减少 ( p > 0.05) NH 3气体排放,并且有减少总硫醇的趋势。日粮中添加 AJE 导致血液蛋白浓度水平线性增加。此外,饲喂逐渐增加 AJE 补充剂水平的育肥猪,屠宰后第 5 天和第 7 天的滴水损失呈线性减少( p > 0.05)。在第 5 周和第 10 周期间,饲喂分级水平 AJE 补充剂的猪的背膘厚度和瘦肉百分比呈线性增加 ( p < 0.05)。 因此,我们得出结论,日粮中添加 AJE 与棕榈仁粕和菜籽粕可能有利于提高育肥猪的生长性能、营养物质消化率、粪便微生物、血液增殖、肉质并减少粪便气体排放。
