动物营养动物营养
兽医寄生虫学兽医寄生虫学

背景情况:

菌病在 brojler 生产中构成重大肠道挑战,因菌病定位剂的限制而加剧.
疫苗的成本限制了它们的广泛应用,需要替代的控制策略.

研究的目的:

评估各种营养策略的有效性,以减轻肉中亚临床Eimeria感染的影响.
为了确定可以支持肉在菌病下表现的饮食干预措施.

主要方法:

576只雄性罗斯308肉被分配给八种饮食治疗,包括对照剂和特定补充剂 (全麦,西-寡糖,高脂肪,高碳水化合物,氨酸+分支链氨基酸,甲酸).
在第14天,鸟类受到Eimeria maxima和E. acervulina卵囊的挑战.
监测了性能数据 (料转换比率),卵囊脱落和病变得分.

主要成果:

与阳性对照相比,氧糖 (XOS),高碳水化合物 (HC) 和甲酸 (SB) 治疗显著改善了鸟类的生长性能.
高脂肪和三氨酸+分支链氨基酸增加了Cecal Bacteroides spp.
XOS和HC数量减少了便卵囊的数量,证实了轻度的Eimeria挑战而没有增加死亡率.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Fungal Phylum Microsporidia

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
