概括
在生猪生产中优化光强度是可持续性的关键. 虽然较高的光线水平增加了污染,但它们改善了休息行为. 建议在空间梯度上采用均的照明,以获得更好的环境和经济效益.
科学领域:
- 动物科学动物科学
- 农业工程 农业工程
- 环境科学 环境科学
背景情况:
- 在畜牧业向发光二极管 (LED) 的过渡需要了解最佳的照明策略.
- 生猪生产的可持续性需要评估社会,环境和经济因素.
研究的目的:
- 调查不同强度光线对养殖猪的可持续性指标的影响.
- 为了比较均的光强度与空间梯度,以优化空间使用和减少污染.
主要方法:
- 应用了四种光处理:低 (45卢克斯),中 (198卢克斯),高 (968卢克斯) 均强度,以及空间梯度 (71-330卢克斯).
- 评估了对氨排放,空间利用,笔污染,体重增加,尸体质量和经济因素的影响,对448头猪进行了两批的评估.
主要成果:
- 较高的光强度 (中高) 增加了休息区的使用量,但也导致了养区的污染.
- 与低均强度相比,空间梯度照明增加了氨排放,并没有改善空间利用或减少污染.
- 体重增加,尸体质量,用水和药物的使用没有受到光强度的显著影响. 电力使用和照明系统成本随着强度的提高而增加.
结论:
- 空间光度梯度没有提高空间利用或减少现有住房中的污染,并增加了氨排放.
- 均的光强度,特别是较低的光强度,可能更有利于减少环境影响和成本.
- 需要进一步优化光源密度,以平衡照明需求与电力消耗和系统成本.

01:01Production Efficiency
16.8K
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).

01:11Testing a Claim about Mean: Known Population SD
2.7K
A complete procedure of testing the hypothesis about a population mean is explained here.
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
