概括
转基因,具有较高的蛋白质含量,减少了超过20%的肉饮食中的大豆粉需求. 这一变化与商业相比,并没有对料转换效率产生负面影响.
科学领域:
- 动物科学动物科学
- 遗传学 遗传学 是一个
- 农业科学 农业科学
背景情况:
- 是动物料的关键谷物.
- 转基因作物 (转基因作物) 在营养成分方面提供了潜在的改善.
- 优化肉饮食对于高效的肉类生产至关重要.
研究的目的:
- 为了比较肉的生长性能,食含有转基因糖果的饮食与传统商业糖果相比.
- 评估转基因糖果中蛋白质度较高对营养的影响.
- 评估对料摄入量,体重增加,料转化率 (FCR),营养消化能力和肉类产量的影响.
主要方法:
- 养288只罗斯308只肉 (14-35天后) 基于转基因或商用杂交的饮食.
- 确保饮食是异和异能.
- 分析了粉和蛋白质的生长性能,料摄入量,FCR,明显的乳腺消化能力 (AID),氨基酸消化能力和母乳肉的产量.
主要成果:
- 商业支持略高的体重增加 (2.55%) 和料摄入 (2.74%).
- 转基因的FCR (1.255比1.257) 和AMEn (明显的代谢能量修正为零) 较高.
- 粉和蛋白质消化能力没有显著差异,但商业糖果产生的乳房肉更多 (6.33%).
结论:
- 具有较高蛋白质含量的转基因允许显著减少大豆的含量 (20.5%),而不会影响 brojler 料转换效率.
- 转基因糖果中氨基酸消化能力的潜在固有改善被建议,可能是由于咖啡因蛋白质体的修改.
- 虽然商业糖果导致了更高的乳肉产量,但转基因糖果提供了一个有希望的替代品,可以减少对禽类食中的大豆粉的依赖.

Transgenic Plants
7.2K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Plant Breeding and Biotechnology
18.9K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Hybridoma Technology
14.7K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.
