概括

脱离小肠吸收的蛋白质氨酸,增强了反动物的产量. 在脂矩阵中封装氨酸,有或没有素提取物,改善了绵羊的营养利用率和食效率,而不会影响整体性能.

科学领域:

动物营养动物营养
动物生理学动物生理学
料科学料科学

背景情况:

饮食中的蛋白质对于反动物的生产至关重要.
绕道蛋白 (逃生蛋白) 可以通过满足未被肠微生物蛋白质合成满足的需求来改善营养利用.
氨酸是一种必需的氨基酸,其旁路形式可以提高动物的表现.

研究的目的:

为了评估脂基质矩阵作为羊中脱离 lysine 的封装剂.
评估素提取物作为脱离氨酸补充剂的辅助剂的有效性.
为了确定脱离氨酸对羊的营养消化能力,进食效率和生理参数的影响.

主要方法:

在一个随机的块设计中,使用了40只Santa Ines × Dorper羊.
应用了四种饮食治疗:控制,自由氨酸,逃脱氨酸和逃脱氨酸 + 氨酸提取物.
评估的参数包括料摄入量,营养物质消化能力,进食效率,吞行为,直肠温度和血液参数.

主要成果:

与自由氨酸相比,脱离氨酸,含有或不含氨酸,增加了总可消化的营养素 (TDN) 和干物质 (DM) 的摄入效率和aNDF摄入效率.
脱离lysine + tannin组的以太提取物摄入量更高.
原蛋白消化能力在对照组和脱离 lysine + tannin 组中更高.
没有观察到对整体性能,料转换或血液参数的显著影响.
羊食逃脱氨酸 + 氨酸后显示减少大颗粒和改善peNDF (NDF颗粒排放).

结论:

脂基质矩阵在反动物中有效地封装了逃脱溶.
素提取物可以充当辅助剂,可能增强脱离氨酸的好处.
脱离氨酸补充剂可以提高羊的营养利用率和食效率.
脱离氨酸饮食不会对动物的表现或健康指标产生负面影响.

Acute Respiratory Failure-V

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Amino Acid Catabolism

Amino Acid Catabolism

Microorganisms rely on proteins as an essential carbon and energy source, particularly in environments with limited polysaccharides or lipids. However, proteins are too large to cross the plasma membrane unaided, necessitating enzymatic degradation. Microbes secrete extracellular proteases and peptidases that hydrolyze proteins into peptides, which can then be transported across the membrane. Once inside the cell, intracellular proteases degrade these peptides into free amino acids, which...

Microbial Leaching

Microbial Leaching

Microbial leaching, also known as bioleaching, is an environmentally favorable method for extracting metals from low-grade ores using specific microorganisms. This biotechnological approach is particularly valuable for mining operations targeting copper, gold, and uranium, where traditional extraction methods may be economically or environmentally impractical.Copper Leaching and Microbial CatalysisIn copper bioleaching, crushed ore is arranged into heaps and irrigated with a dilute sulfuric...

Microbes in Food Production

Microbes in Food Production

Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
