概括
在家禽料中逐步补充Scarabaeiform幼虫 (Sl) 粉,可以改善生长和肉质. 这种方法减轻了与持续使用Sl相关的负面免疫反应和肠道微生物群变化.
科学领域:
- 动物营养
- 可持续的农业
- 基于昆虫的料
背景情况:
- 全球粮食安全的挑战需要替代牲畜的蛋白质来源.
- 大豆粉短缺影响了畜牧业的可持续发展.
- 虫幼虫 (Sl) 提供了一个有前途的替代蛋白质,因为它具有营养上的好处.
研究的目的:
- 评估黄羽肉用Sl粉代替大豆粉的剂量阶段动态.
- 评估粉对生长性能,屠宰特征,肉质,免疫功能和肠道微生物群的影响.
- 确定在家禽养系统中应用粉的最佳策略.
主要方法:
- 150只雄性肉被分为五个组:对照组,4%的Sl (完整),8%的Sl (完整),4%的Sl (阶段性) 和8%的Sl (阶段性).
- 在整个试验期间 (完整) 或在早期中期 (分阶段,第1至第42天) 补充了Sl餐.
- 评估包括生长性能,屠宰特征,肉质,免疫参数 (细胞因子,IgA,IgG) 和肠道微生物分析.
主要成果:
- 阶段性补充 (4%和8%) 在早期中期生长阶段 (1-42天) 改善了体重和体重增加.
- 连续补充Sl可以降低后期 (43-63天) 的生长率.
- 阶段性Sl组显示脂质沉积增加和改善幽默免疫力 (IgA,IgG),同时减轻过度的促炎细胞因子反应.
结论:
- 逐步补充4%的粉 (1-42天) 是一种有效的替代大豆粉的策略,可以提高 brojler 的性能和肉质.
- 这种方法优化了营养利用,改善了脂质沉积,并支持免疫功能而没有有害影响.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:16Primary Lymphoid Organs
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
