概括

一种混合脂质来源,鱼-棕-大米油混合物 (FPRO),改善了断奶猪的原油消化能力和肠道健康. FPRO增强了营养物质运输体表达和肠道微生物群,表明其对猪营养的潜力.

科学领域:

动物营养动物营养
胃肠病学胃肠病学
脂质代谢脂质代谢是什么

背景情况:

饮食中的脂质显著影响猪生长性能和肠道健康.
了解不同脂质来源的影响对于优化猪的饮食至关重要.
大豆油 (SO),鱼棕油与大米油混合物 (FPRO) 和子棕油与大米油混合物 (CPRO) 代表了不同的脂质特征.

研究的目的:

评估不同食脂质来源对断奶猪生长表现和肠道健康的影响.
为了比较SO,FPRO和CPRO对营养物质消化能力,肠道形态,免疫反应和营养物质运输体表达的影响.

主要方法:

72只断奶猪被随机分配到三个饮食治疗组 (SO,FPRO,CPRO) 持续28天.
测量包括营养消化能力,血清细胞因子水平,肠的高度,肠道微生物群的组成,紧密结合蛋白和营养载体的表达.

主要成果:

与SO和CPRO组相比,FPRO组表现出更高的原油脂肪,干物质,灰和总能量消化率.
与SO组相比,FPRO和CPRO组分别表现出骨和骨中的毛高度增加.
FPRO补充剂增加了乳酸菌的丰富性,并增强了紧密结蛋白 (ZO-1,Claudin-1,Occludin) 和营养物质运输体 (CAT-1,PepT1,FATP1,SGLT1) 的表达.
与SO组相比,FPRO组的血清中介质素-6 (IL-6) 度降低了.

结论:

食FPRO显著改善了断奶猪的营养消化能力和肠道健康.
混合脂质来源,如FPRO增强肠道屏障功能和营养吸收.
作为有益的脂质来源,FPRO有望改善小猪生长性能和肠道健康.

Lipids: Dietary Sources and Requirements

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...

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.
