概括
养母活着的黑士兵幼虫 (BSFL) 到30%的饮食不会对蛋质量产生负面影响. 补充BSFL改变了蛋黄脂肪酸概况,但保持了蛋的整体成分和商业用途的安全性.
科学领域:
- 动物科学动物科学
- 禽类的营养 养
- 食品科学 食品科学 食品科学
背景情况:
- 活昆虫幼虫,特别是黑士兵幼虫 (BSFL),被提议作为密集养殖产母的创新环境丰富.
- 了解BSFL补充剂对蛋质量的影响对于其在商业家禽生产中采用至关重要.
研究的目的:
- 评估产卵母的年龄和用活生生的BSFL补充饮食对蛋质量属性的影响.
- 用核磁共振 (NMR) 光谱分析蛋的化学成分,脂肪酸 (FA) 概况和代谢概况.
主要方法:
- 108只Lohman棕色被食商业饮食或同样的饮食补充15%或30%的活BSFL.
- 从16周到34周的年龄被监测,评估了蛋质量参数.
- 分析了蛋的化学成分,FA概况和代谢概况.
主要成果:
- 用BSFL进行的饮食治疗没有影响蛋或蛋的整体质量属性或宏观营养素组成.
- 补充BSFL显著改变了蛋黄的FA配置,增加和脂肪酸 (SFA) 和多不和脂肪酸 (PUFA),同时减少单不和脂肪酸 (MUFA).
- 的年龄显著影响了各种蛋质量特征,包括体重,的特征和代谢概况.
结论:
- 对于产母来说,每日料摄入量的高达30%的活BSFL的补充是安全的.
- 可以将BSFL纳入产母的饮食中,而不会损害基本的蛋质量参数.
- 虽然FA概况受到修改,但BSFL在家禽养殖中显示出作为可持续料成分的潜力.

02:55The Nucleolus
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
01:26Bacterial Protein Maturation
Bacterial protein maturation is a tightly regulated process that ensures newly synthesized polypeptides achieve correct functional conformations. This maturation involves a series of modifications, folding events, and quality control steps, often assisted by specialized chaperone proteins.N-Terminal ModificationsThe maturation of bacterial polypeptides begins cotranslationally as the polypeptide exits the ribosome. The first amino acid, N-formylmethionine (fMet), is typically modified at the...
