概括
在 brojiler料中补充Areca坚果提取物 (ANE) 显著改善了生长性能和肉质. 牛肉的最佳ANE剂量是100-200毫克/公斤,促进肌肉发育而不影响屠宰性能.
科学领域:
- 动物科学动物科学
- 营养科学 营养科学
- 禽畜科学 禽畜科学 禽畜科学
背景情况:
- 中国禁止使用抗生素料添加剂,需要为牲畜和家禽提供天然替代品.
- 虽然Areca catechu L (AN) 具有已知的生物活性,但其作为肉料添加剂的用途尚未得到充分研究.
- 了解阿雷卡坚果提取物 (ANE) 的作用对于开发新型料添加剂至关重要.
研究的目的:
- 研究不同水平的ANE对Arbor Acres (AA) 肉生长性能,屠宰性能和肉质量的影响.
- 为了确定ANE在 brojiler料中的最佳剂量.
- 评估ANE作为抗生素生长促进剂的潜在天然替代品.
主要方法:
- 128只一天大的AA肉被随机分配到八个饮食组,在49天内接受0至400毫克/公斤的ANE水平.
- 监测了生长性能参数,包括体重和料与重量比率.
- 肉质的评估包括pH值,颜色,切削力和营养成分. 还分析了与肌肉发育相关的基因表达.
主要成果:
- 100和200毫克/公斤的ANE补充剂在21天后显著增加了体重,并降低了料与体重的比率.
- 剂量为200mg/kg的ANE在49天后显著增加了平均体重.
- ANE改善了胸部和腿部肌肉的pH值,黄色,剪切力,原油脂肪和原油蛋白质含量,并提高了肌肉发育基因 (Myf5,Myf6,MyoD1,IGF-1,IGF-2).
结论:
- 适当的ANE补充剂 (100-200毫克/公斤) 可以提高 brojler 的生长性能和肉质.
- ANE促进肌肉发育,对屠宰性能没有任何不良影响.
- ANE为家禽产业提出了一种有前途的天然料添加剂,需要进一步研究.

Fruit Development, Structure, and Function
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.
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...
