概括
胆酸 (BA) 和西兰酶 (Xyl) 补充剂改善了 brojlers 的脂肪消化能力. 虽然Xyl降低了消化器的粘度,但BA增加了血清脂质,两者都对脂肪消化能力产生了积极的影响.
科学领域:
- 动物营养 动物营养
- 禽畜科学 禽畜科学 禽畜科学
- 生物化学 生物化学
背景情况:
- 饮食成分显著影响肉的表现和健康.
- 胆汁酸 (BA) 对于脂肪的消化和吸收至关重要.
- 克西兰酶 (Xyl) 酶可以降解非粉多糖,从而有可能改善营养利用.
研究的目的:
- 评估补充胆酸 (BA) 和胆酶 (Xyl) 对肉生长,脂肪消化能力,血清脂质概况和胆管消化粘度的影响.
- 了解BA和Xyl对肉生理反应的单独和联合影响.
主要方法:
- 对720只雄性肉进行了因子实验,使用三种BA (0%,0.25%,0.50%) 和三种Xyl (0%,0.05%,0.10%) 的水平.
- 测量包括生长表现,料摄入量,体重增加,料转化率,血清脂质代谢物 (胆固醇,LDL),脂肪消化能力和皮质消化粘度.
- 实验持续时间为35天 (从7天到42天).
主要成果:
- 无论是BA还是Xyl补充剂都没有显著影响料摄入量或体重增加.
- BA补充剂线性增加了脂肪的消化能力.
- 克西兰酶补充剂通过降解阿拉比诺克西兰,有效地降低了阴道消化器的粘度.
- 补充BA,特别是0.50%,在7-21天大时显著增加血清胆固醇和LDL水平.
结论:
- 克西兰酶有效地降低了以小麦为基础的饮食养的 brojlers 的ileal digesta 粘度.
- 胆酸补充可以提高脂肪的消化能力,但可以增加血清胆固醇和LDL水平.
- 联合BA和Xyl补充剂线性地改善 brojlers中的脂肪消化能力.

Lipid Digestion
91.8K
Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

Lipid Absorption
481
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...
