概括
肉幼早期获得料和水可以在第一周显著改善小肠发育. 然而,这些对小表面积和洞穴深度的有益影响在肉生命周期的晚期会减少.
科学领域:
- 动物科学 动物科学
- 鸟类生理学 鸟类生理学
- 胃肠道形态学 胃肠道形态学
背景情况:
- 肉的生长速度受到小肠的高度和化后的表面积的限制.
- 肠道发育,包括小的高度,在化后的第一个星期是最快的.
研究的目的:
- 评估化后立即获得料和水对 brojiler 小肠发育的影响.
- 为了评估肠道结构和形态变化 (形高度,表面积,密室深度) 的变化,以应对早期营养.
主要方法:
- 10万只Ross 308肉蛋被分为两个组:HatchCare (HC) 早期获取料/水和标准 (ST) 传统化.
- 在化后的1,7,21日和35天收集了十二指肠,十足肠和阴茎样本.
- 形态测量分析包括小的高度,宽度,表面积 (VSA),密室深度,小与密室比率 (VCR) 和杯细胞计数.
主要成果:
- 早期养 (HC组) 在第7天显著增加了十二指甲腺和阴茎的VSA.
- 密室深度最初在第一个星期增加了头和骨,然后在第21天和35天减少了头.
- 十二指肠/大肠中的杯状细胞数量没有受到影响,但在HC组的21日和35日的阴茎中减少了.
结论:
- 化后立即获得料和水,为肉小肠在第一周内发育提供了显著的好处.
- 这些对肠道形态学的积极影响在整个肉生长期间都不会持续下去.
- 早期营养在早期肠道成熟中起着至关重要的作用,但其长期影响需要进一步研究.

Gastrulation
66.4K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Anatomy of the Intestines
86.8K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
