概括
改善羊的福利可以显著降低温室气体 (GHG) 排放强度. 研究表明,不良福利,像腿一样,增加了每公斤肉的排放量,突出了动物健康和气候影响之间的联系.
科学领域:
- 农业科学 农业科学
- 环境科学 环境科学
- 动物科学动物科学
背景情况:
- 与农场利能力和动物福利平衡气候问题至关重要.
- 有限的研究量化了畜牧业中动物福利和温室气体 (GHG) 排放之间的关系.
- 英国低地 (L) 和山地 (H) 羊群系统面临着影响可持续性的共同福利挑战.
研究的目的:
- 量化动物福利损害对英国绵羊养殖中温室气体排放的影响.
- 模拟共同的福利挑战及其对排放强度 (EI) 的影响.
主要方法:
- 利用了两个苏格兰的案例研究农场,代表了L和H系统的高福利基线.
- 使用文献数据建模了受损福利场景 (惰,寄生虫,不充分的养/庇护,高羊羔死亡率).
- 使用Agrecalc ©生命周期评估工具估计的摇篮到农场门的温室气体排放量.
主要成果:
- 大多数受损福利场景的总体农场排放量略有下降,但由于肉类生产减少,排放强度 (EI) 增加.

01:01Production Efficiency
16.7K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

00:51Energy 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...
