概括

将活生生的黑兵 (BSF) 幼虫给本土的双重用途,通过增加积极的行为和减少羽毛,改善了它们的福利. 这种食丰富提高了Bionda Piemontese的羽毛和生产力,而不会对便微生物群产生负面影响.

科学领域:

动物科学动物科学
禽畜科学禽畜科学禽畜科学
动物福利动物福利

背景情况:

饮食生活昆虫幼虫,特别是黑兵 (BSF) 幼虫,是密集养殖的新型环境丰富.
它们在本地双重用途的品种,如Bionda Piemontese (BP) 和Bianca di Saluzzo (BS) 中的有效性仍未得到研究.

研究的目的:

为了评估活生生的BSF幼虫作为环境丰富对BP和BS的影响.
评估对鸟类表现,行为,整体状况,排泄中的皮质代谢物 (ECM) 和微生物群的影响.

主要方法:

90个BP和90个BS母 (308天) 被分为对照组 (商用料) 和BSF组 (商用料+每天6%的BSF幼虫) 持续90天.
评估了幼虫摄入时间,每日料摄入量 (DFI),活体重量,产卵率,料转换比率,包皮分数,行为,ECM和便微生物群.

主要成果:

随着时间的推移,BSF幼虫的消费量增加;BSF养的母的DFI较低. 养BSF的白兰卡迪萨卢佐的活体体重增加.
养BSF的Bionda Piemontese的产卵率更高,料转换和整体成绩更好. 用BSF养的母表现出更多的积极行为 (清理,,翅膀) 并减少了严重的羽毛.
在BSF养的BS母中,Allopreening的增加. 两组之间没有发现ECM或便微生物群的显著差异.

结论:

活生生的黑兵幼虫可以通过增强积极的行为和减少羽毛,积极影响本地双重用途的福利.
施用BSF幼虫显示出提高生产性能和羽毛状况的潜力,特别是在Bionda Piemontese品种中.
这种丰富策略不会对这些品种的排泄微生物群或皮质代谢物水平产生不利影响.

Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Limits to Natural Selection

Limits to Natural Selection

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

What is Natural Selection?

What is Natural Selection?

Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.
