概括
基于激素的系统生殖管理计划显著改善奶牛的生殖表现和经济回报. 这些计划利用定时人工授精 (TAI) 和重同步协议,与传统的基于诊断的激素治疗相比,提供更高的净收入.
科学领域:
- 畜牧业的生殖生物学和内分泌学.
- 乳牛的生产和管理.
- 农业经济学和模拟建模.
背景情况:
- 目前乳牛群的生殖管理通常依赖于雌激发检测和兽医诊断进行激素干预.
- 基于激素的计划可以提高奶牛的生殖效率.
- 经济评估对于评估不同生殖策略的可行性至关重要.
研究的目的:
- 为了比较系统的,定时的荷尔蒙生殖管理计划与乳牛的基于诊断的治疗方法的经济影响.
- 用生物经济模拟模型评估四种不同的基于激素的生殖管理策略.
- 为了确定哪个计划能产生最高的净经济回报 (NER).
主要方法:
- 一个现有的200头奶牛奶牛群的随机生物经济模拟模型被调整为包括卵巢功能障碍和生育数据.
- 模拟了四个生殖管理计划:一个默认的 (基于诊断) 和三个系统的激素治疗计划 (FTAI,FTAI+ED,ED+TAI).
- 每个计划的年度平均净经济回报 (NER) 被计算出来,考虑了成本 (激素,分娩,料) 和收入 (牛奶,小牛).
主要成果:
- 基于激素的系统计划导致总体成本更高,因为激素的使用增加和更多的怀孕.
- 然而,在系统计划中,从牛奶和小牛增加的收入超过了额外的成本.
- FTAI+ED项目获得了最高的NER (23,764欧元高于违约),其次是FTAI (19,550欧元) 和ED+TAI (14,314欧元).
结论:
- 基于激素的系统生殖管理计划在乳牛群中比传统的基于诊断的方法具有显著的经济优势.
- FTAI+ED计划,涉及双重对比定时人工智能与非怀孕的奶牛检测到期或重新同步,证明最有利于经济.
- 实施系统的激素策略可以改善整体畜群的生殖性能和利能力.

Target Cell Response to Hormones
3.0K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Hormonal Regulation of the Menstrual Cycle
320
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Cloning of Dolly the Sheep
3.4K
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...

Gonadal and Placental Hormones
1.4K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Major Hormones and Their Functions
356
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...
