概括
在奶牛的饮食中用以前的食品 (FFP) 取代谷物谷物可能会提高可持续性. 用FFP补充可可豆 (CBS) 并没有对动物健康产生负面影响,这表明它是牲畜料的有希望的替代品.
科学领域:
- 动物科学动物科学
- 类动物营养 类动物营养
- 可持续农业 可持续农业
背景情况:
- 粮食安全日益提高,需要探索为牲畜提供替代料的原料.
- 谷物谷物是反动物饮食中的主食,但它们的使用受到粮食安全问题的挑战.
- 用以前的食品 (FFP) 取代谷物谷物的对动物健康和生产的影响需要调查.
研究的目的:
- 评估将55%的谷物谷物替换为FFP对早期哺乳乳奶牛的反发酵,甲生产和血液代谢物的影响.
- 评估可可豆 (CBS) 补充剂在基于FFP的饮食中的影响.
- 为了确定季节性变化对这些影响的影响.
主要方法:
- 两次实验 (春季和秋季) 用早期哺乳的荷尔斯坦和红荷尔斯坦奶牛 (每次实验n=17).
- 饮食包括一个控制缩物 (CON),55%的FFP缩物 (FFP-),和5%的CBS缩物 (FFP+) 的FFP.
- 测量包括料摄入量,牛奶产量,反液参数和血液代谢物.
主要成果:
- 与CON相比,FFP和FFP+饮食改变了反体发酵,增加了酸盐比例和水溶性碳水化合物,但减少了粉摄入量.
- 随着FFP+的加入,牛奶中乳糖的百分比下降,而牛奶脂肪的百分比增加.
- 季节性变化影响了料摄入量和血液代谢物水平,但FFP和CBS补充剂没有影响动物健康指标.
结论:
- 用FFP代替谷物谷物,有或没有CBS,似乎是可持续奶牛营养的可行策略.
- 结合FFP和CBS可以在牛奶脂肪含量方面提供好处,而不会对健康产生不良影响.
- 需要进一步的研究来证实这些发现,并优化乳牛的FFP饮食.

Anatomy of the Intestines
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 small...

Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
Microbes in the Production of Fermented Foods
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
