概括

乳牛生殖障碍使农场每年每群牛花费20,013欧元. 急性甲状炎是最昂贵的,每年5,908欧元/群,而预防一种疾病可以减少其他疾病的经济影响.

科学领域:

兽医经济学兽医经济学
乳制品群管理乳制品群管理
牲畜的生殖健康在畜牧业的生殖健康.

背景情况:

乳牛的生殖障碍从周产期到怀孕早期是常见的.
这些疾病可能相互关联,使经济影响评估复杂化.
准确的经济影响数据对于农民来说至关重要,以优先考虑疾病预防战略.

研究的目的:

为了估计七个关键乳牛生殖障碍的经济成本:乳,保留的胎盘,急性子宫炎,临床子宫内膜炎,无排卵,囊性卵巢疾病 (COD) 和亚雌激.
在经济分析中解释这些疾病之间的复杂相互关系.
提供数据,以便在乳牛群管理和疾病预防方面做出明智的决策.

主要方法:

一个现有的动态,随机,基于个体奶牛的生物经济模拟模型被适用于一群200头奶牛.
该模型被扩展,包括研究的七种生殖障碍的相互关系.
运行了九个模拟场景:一个默认场景与所有障碍,八个场景为每个特定障碍的零概率,和一个没有障碍的场景.

主要成果:

所有七种生殖系统疾病的总年平均成本为每只群体20.013欧元 (100欧元/母牛).
急性甲状炎的平均年费用最高,为5,908欧元/群 (30欧元/母牛),而肌痛症的平均年费用最低,为897欧元/群 (4欧元/母牛).
在个案基础上,急性甲状炎是最昂贵的 (€257/病例),而囊性卵巢疾病 (COD) 是最便宜的 (€58/病例).

结论:

生殖障碍之间的相互关系意味着预防一种疾病可以减少其他疾病的发生率和经济影响.
急性甲状炎对乳制品农场造成重大经济负担,需要有针对性的预防和管理策略.
该研究强调了在评估乳牛生殖健康问题的经济影响时考虑相互联系的重要性.

Energy Budgets

Energy Budgets

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

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...

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...
