Summary
Preventing sow abortions is key for pig farming sustainability. Understanding non-infectious and infectious causes helps reduce losses and ensure a stable pork supply.
Area of Science:
- Veterinary Medicine
- Animal Science
- Agricultural Economics
Background:
- Reproductive disorders in sows significantly impact pig industry economics and food security.
- Abortion prevention is more cost-effective than treatment in intensive farming systems.
- Understanding sow abortion causes is crucial for sustainable livestock production.
Purpose of the Study:
- To review factors contributing to sow reproductive disorders.
- To analyze underlying causes and pathogenic mechanisms of pregnancy disorders.
- To outline preventive and control strategies for sow abortions.
Main Methods:
- Literature review of non-infectious factors (environment, management).
- Literature review of infectious factors (viruses, bacteria, parasites).
- Analysis of integrated management approaches and the "One Health" concept.
Main Results:
- Sow reproductive disorders stem from complex interactions of non-infectious and infectious agents.
- Environmental conditions and management practices are significant non-infectious contributors.
- Viruses, bacteria, and parasites are key infectious causes of abortion.
Conclusions:
- Implementing the "One Health" concept in large-scale farming reduces sow abortion rates.
- Integrated management strategies are essential for stable livestock production.
- Effective sow abortion control ensures a reliable global pork supply.

23.2K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

285
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

01:21Nondisjunction
3.7K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...
