概括
发芽粗米 (SR) 可以取代肉饮食中的玉米,改善生长和肉质. 用SR代替45%的玉米提高了 brojler的性能和尸体特征,而不会对健康指标产生负面影响.
科学领域:
- 动物科学动物科学
- 禽类的营养 养
- 料科学 料科学
背景情况:
- 发芽粗米 (SR) 对家禽的饮食提供了潜在的营养益处.
- 关于SR作为肉料中玉米替代品的研究有限.
研究的目的:
- 评估用SR取代玉米对 brojler生长表现的影响.
- 评估SR对尸体质量,肉类脂肪酸概况和生理参数的影响.
- 为了确定SR在 brojiler饮食中的最佳含量水平.
主要方法:
- 一个完全随机的设计与四个治疗组 (0,15,40,45%玉米的SR替代).
- 每组都有六个复制品,每个复制品有10只鸟.
- 评估生长性能,尸体产量,肉的pH值,免疫器官体重,血液脂质,肝酶和脂肪酸概况.
主要成果:
- 增长性能 (活体体重,体重增加) 和尸体质量 (尸体,大腿,乳房重量) 显著改善,包括高达45%的SR.
- 料转换率和料摄入量随着SR水平的增加线性下降.
- 免疫器官重量 (胸腺,) 随着SR的纳入,线性增加.
- 脂肪酸概况,包括和和不和脂肪酸,在SR含量较高时显示增加.
- 在损失,血脂或肝酶概况方面没有发现显著差异.
结论:
- 在肉的饮食中,将45%的玉米替换为发芽的粗米可以提高生长性能和尸体质量.
- 作为家禽料中具有成本效益和营养成分,SR显示出前景.
- 进一步的研究可以探索SR纳入的长期影响和经济可行性.

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.

Transgenic Plants

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...
