概括
补充泰国本土的肉牛用酵母废弃物颗粒 (CWYWP) 发酵的废弃物在干物摄入量的4-6%提高了原始蛋白质摄入量和消化能力. 这种饮食增强也促进了肠细菌种群和 propionate 度.
科学领域:
- 动物营养 动物营养
- 动物生理学 动物生理学
- 农业科学 农业科学
背景情况:
- 在泰国本土的肉牛中,以草为基础的饮食是常见的,但往往缺乏足够的营养.
- 需要替代性料补充剂来改善牛的营养和生产力.
- 用酵母废料颗粒发酵的废料 (CWYWP) 是一种潜在的料添加剂.
研究的目的:
- 评估CWYWP补充剂对泰国本土肉牛的料摄入量,小参数和血液代谢物的影响.
- 为了确定CWYWP的最佳含量水平,肉牛食以草为基础的食.
- 评估CWYWP对营养物质消化能力和乳头发酵特性的影响.
主要方法:
- 在21天的时间里,四头泰国本土的肉牛被用在4x4拉丁方形设计中.
- 动物接受了CWYWP补充剂0%,2%,4%或6%的每日干物质 (DM) 摄入量.
- 分析了料摄入量,体特征 (pH,氨-,微生物种群) 和血液代谢物.
主要成果:
- 补充CWYWP线性增加了总干物质摄入量和原蛋白 (CP) 摄入量和消化能力,峰值水平为6% (p < 0.05).
- 液pH值,血尿和原生动物种群没有受到影响 (p > 0.05).
- 氨水平稳定,而反动物细菌种群和酸度在6%的CWYWP含量时显著增加 (p <0.05).
结论:
- 补充泰国本土肉牛4%或6%的CWYWP可以提高CP摄入量和消化能力.
- 包括CWYWP在内对菌群和 propionate度产生了积极的影响.

01:27Microorganisms in Agriculture and Food industry
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...
01:18Amino 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...
01:27Microbes in the Production of Fermented Foods
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
01:25Biofuels
The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
01:28Microbial Bioremediation of Plastics
Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...
