Abstract

Silymarin is the flavonoid extracted from Silybum marianum seed. It has anti-inflammatory and antibacterial properties, and it supports liver health. The growth performance parameters, nutrient digestibility, and blood profile in growing pigs fed the dietary Silybum marianum seed extract were analyzed in this study. A total of 196 crossbred growing pigs ((Yorkshire × Landrace) × Duroc) were allocated into three dietary groups: CON: basal diet; TRT1: basal diet with 0.05% Silybum marianum seed extract; and TRT2: basal diet with 0.10% Silybum marianum seed extract. Results showed that pigs fed with Silybum marianum seed extract up to 0.10% increased average daily gain ( p < 0.10) and feed intake ( p < 0.05). The digestibility of dry matter, nitrogen, and energy were increased linearly ( p < 0.05) with addition of Silybum marianum seed extract up to 0.10%. However, serum bile acids, alanine aminotransferase (ALT), and aspertate aminotransferase (AST) were not changed ( p < 0.05). In conclusion, the significant improvements in average daily gain, feed intake, and nutrient digestibility indicate that Silybum marianum seed extract can positively influence the growth of growing pigs. Finally, natural feed additives like Silybum marianum seed extract may be used as an efficacious growth promoter and ultimately contributing to sustainable pig farming.
水飞蓟籽提取物作为一种潜在的植物性饲料添加剂,可提高生长猪的生长性能和营养物质消化率
水飞蓟素是从水飞蓟种子中提取的类黄酮。它有消炎和抗菌的特性,它支持肝脏健康。本试验对饲粮中添加水飞蓟籽提取物的生长猪的生长性能参数、营养物质消化率和血液特征进行了分析。试验选用196头杂交生长猪((大约克×长)×杜洛克),分为3个饲粮组:CON:基础饲粮;TRT1:添加0.05%水飞蓟籽提取物的基础饲粮;TRT2:添加0.10%水飞蓟籽提取物的基础饲粮。结果表明:饲粮添加水飞蓟籽提取物0.10%可提高猪的平均日增重(p <0.10)和采食量(p <0.05)。干物质消化率、氮消化率和能量消化率呈线性增加(p <0.05),水飞蓟籽提取物添加量为0.10%。血清胆汁酸、谷丙转氨酶(ALT)和谷草转氨酶(AST)无明显变化(p <0.05)。综上所述,水飞蓟籽提取物显著提高了生长猪的平均日增重、采食量和营养物质消化率,表明水飞蓟籽提取物对生长猪的生长有积极影响。最后,水飞蓟籽提取物等天然饲料添加剂可能作为一种有效的生长促进剂,最终有助于可持续养猪。

期刊介绍: Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
