概括

酸丁酸盐 (SB) 补充剂改善了低口重 (LHW) brojler 的表现和肠道健康. 接受0.3%SB的LHW小显示出增长,肠道完整性和有益的肠道微生物群,缓解了低于最佳的性能.

科学领域:

动物科学动物科学
禽类的营养养
肠道健康研究研究肠道健康研究

背景情况:

brojlers 的低化重量 (LHW) 对生长和表现产生负面影响.
已知酸盐 (SB) 可以增强肠道健康并促进生长.

研究的目的:

为了研究卵内注射酸盐 (SB) 对肉的表现和肠道健康的影响.
为了确定SB是否可以改善生长和肠道健康,特别是在患有LHW的肉中.

主要方法:

在第12个化日,Ross 308个肉蛋注射了盐水或SB (0.1%,0.3%,0.5%).
化后,子根据化重量 (高HW与LHW) 进行分类,并分配到治疗组.
分析了生产参数,肠道形态,基因表达 (肠道屏障,免疫反应) 和肠微生物群.

主要成果:

SB没有影响化能力;高HW小的表现优于LHW对照.
0.3%SB显著改善了LHW小的生长,体重和料转换率.
SB调节了肠道屏障基因表达,减少了肠道炎症,改变了肠道微生物群的组成,有利于LHW中的有益细菌.

结论:

口重量显著影响肉的表现和对SB的反应.
低水温肉从0.3%的SB中获得了实质性的好处,从而改善了生长,肠道健康和肠道微生物群的形状.
SB代表了一种可行的策略,以提高来自LHW的肉的表现.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

What is Monogastric Digestion?

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
