Question

Describe how rainfall affects the growth of animals

Answer 1

Answer:

Climate change is expected to exert an overwhelming negative effect on livestock health and welfare. Several studies suggest that the expected increase of air temperatures might reduce the risk of death and improve health and welfare of humans and livestock living in areas with very cold winters.

The negative effects of climate change on animal health and welfare will be the consequence of combined changes of air temperature, precipitation, frequency, and magnitude of extreme weather events and may be both direct and indirect.

The direct effects of climate change may be due primarily to increased temperatures and frequency and intensity of heat waves. Depending on its intensity and duration, heat stress may affect livestock health by causing metabolic disruptions, oxidative stress, and immune suppression causing infections and death.

The indirect effects of climate change are primarily those linked to quantity and quality of feedstuffs and drinking water and survival and distribution of pathogens and/or their vectors.

Development and application of methods linking climate data with disease occurrence should be implemented to prevent and/or manage climate-associated diseases.

Answer 2

Answer:

Studies have showed that advanced rainfall during the growing period can lead to an improvement in the utilization of soil water, which is beneficial to root growth19. By contrast, delayed rainfall often increases the availability of soil water at the later stage of growth, thus delaying the plant senescence
