概括

草甘单酸盐 (GML) 改善了棕油 (PO) 的能量消化能力,但不是大豆油 (SO) 饮食. 然而,这并没有提高的生长性能,SO养的鸟类显示出比PO养的鸟类更好的养效率.

科学领域:

动物营养动物营养
料科学料科学
禽畜科学禽畜科学禽畜科学

背景情况:

脂质来源显著影响家禽的营养消化能力和生长性能.
乳化剂经常被添加到动物的饮食中,以改善脂质利用.
糖单酸盐 (GML) 是一种乳化剂,对能量吸收有潜在的益处.

研究的目的:

调查脂质来源 (棕油与大豆油) 和GML纳入对 brojlers和poults的能量消化能力和生长性能的相互作用影响.
评估GML在改善毛能 (GE) 和整体性能指标的表面全管消化能力 (ATTD) 的有效性.

主要方法:

通过使用肉和进行了两项试验.
饮食因脂质来源 (棕油或大豆油) 和GML含量水平 (0%,0.05%,或0.10%) 而有所不同.
总能量 (GE) 的看似全管道消化率 (ATTD),平均每日料摄入量 (ADFI),平均每日增益 (ADG) 和料效率都被测量.

主要成果:

添加GML改善了棕油 (PO) 饮食中的GE的ATTD,但对大豆油 (SO) 饮食没有影响.
基于PO的饮食显示,当没有添加GML时,与SO饮食相比,GE消化能力较低.
包括GML影响了ADFI和ADG在脂质来源之间不一致,并且没有提高料效率,SO饮食始终比PO饮食产生更好的料效率.

结论:

在肉饮食中,GML提高了PO的能量消化能力,但这种好处并没有转化为改善的生长性能.
在家禽食中,大豆油 (SO) 与棕油 (PO) 相比,支持更高的料效率,而不管GML补充.
作为乳化剂的GML的有效性取决于脂质来源,对料摄入量和生长指标的影响有所不同.

Lipid Digestion

Lipid Digestion

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.

Production Efficiency

Production Efficiency

Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Fats as Energy Storage Molecules

Fats as Energy Storage Molecules

Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl-CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis...
