- Culling and mortality of dairy cows: why it happens and how . . .
However, the growth and distribution of the dairy industry is limited by many factors such as culling and mortality of dairy cows Several studies highlight reproduction failures, old age, poor milk yield, diseases (mastitis, lameness, and dystocia), and heat stress as some reasons for culling of dairy cows
- 1. 5 or 2 degrees Celsius of additional global warming: Does . . .
A study on extreme heat published around the same time as the U N report projected that about 14% of the world’s population would be exposed to extreme heat waves once every five years if global temperature increases are held to 1 5°C That percentage would jump up to 37% with a rise of 2°C
- How the climate crisis is impacting jobs and workers | World . . .
If you are reading this in a temperature-controlled office building, heat stress is probably not top of your list of worries right now And yet, in just seven years, up to 3 8% of total working hours worldwide could be lost to climate-induced high temperatures , according to the International Labour Organization (ILO)
- Working on a warmer planet: The effect of heat stress on . . .
The phenomenon of heat stress refers to heat received in excess of that which the body can tolerate without physiological impairment It is one of the major consequences of global warming By 2030, the equivalent of more than 2 per cent of total working hours worldwide is projected to be lost every year, either because it is too hot to work or
- Heat Stress Kills Estimated 10,000 Head of Kansas Feedlot Cattle
The current heat wave blazing through Kansas feedlots has killed an estimated 10,000 head of fat cattle Final death numbers continue to come in, but that early estimate was shared with DTN by
- The relationship between the number of consecutive days with . . .
Heat stress is known to affect performance of dairy cows experiencing prolonged periods of high temperature and relative humidity Less is known about its effects in cooler climates The goals of the present study were to determine the prevalence of days susceptible to cause mild heat stress in dair …
- Modeling the relationship between heat stress, feed intake . . .
On average, cows housed in barns without evaporative cooling systems had a reduction in DMI of 1 30 kg d and increased rectal temperature in 0 22°C in relation to those housed in barns with evaporative cooling systems Dry matter intake decreased as THI increased, but the reduction was greater for noncooled cows as THI values increased
