概括

的蛋产量增加与改善肠道健康和抗氧化能力有关. 这项研究表明,增强的肠道屏障功能和特定的肠道细菌对产母的蛋产量和质量产生积极影响.

科学领域:

动物科学动物科学
禽畜科学禽畜科学禽畜科学
胃肠病学胃肠病学

背景情况:

尽管基因和条件均,但较老的产卵母的蛋产量不同.
肠道功能被假设是影响这些生产差异的关键因素.

研究的目的:

为了比较不同产卵率的产母的肠功能.
研究肠道健康,生殖系统功能和卵子生产之间的关系.

主要方法:

选择了120只罗曼粉红色 (66周大) 产卵母,分为低 (LR),中 (MR) 和高 (HR) 产卵率组.
评估了卵子产量,卵子质量,卵巢抗氧化酶活性,基因表达 (Nrf2,Caspase 3),肠道屏障基因 (CLDN1,MUC-2) 和肠道微生物群组成.
利用相关性分析来确定微生物丰富度和卵子质量之间的关系.

主要成果:

HR组的卵产量,卵质量,料效率和卵质量 (豪格单位,蛋强度) 显著提高.
HR组表现出卵巢抗氧化酶活性 (CAT,T-AOC,GSH) 增加,Nrf2表达上调,Caspase 3表达下调.
肠道分析显示,HR组中CLDN1和MUC-2的表达升高,同时Firmicutes,Faecalibacterium和Lactobacillus的丰富性更高,以及眼膜中较低的Proteobacteria和Actinobacteriota.
在HR组的部微生物群中观察到较低的α多样性指数.

结论:

的较高产卵率与改善肠道屏障功能,特定的有益肠道微生物群 (Faecalibacterium,Lactobacillus) 和增强生殖系统健康 (抗氧化能力) 相关.
Nrf2信号通路和SIRT1相关的亡通路与在高产母中观察到的卵巢功能增强有关.

Sperm Structure and Semen Composition

Sperm Structure and Semen Composition

During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

Infertility in Males

Infertility in Males

Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Infertility in Females

Infertility in Females

Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of endometrial...
