Calf jackets serve several important purposes in farming and calf rearing , including:

1. Keeping calves warm: Newborn and young calves have a relatively low body weight and minimal body fat, which makes them vulnerable to hypothermia in cold weather. Calf jackets in Ireland provide an extra layer of insulation to help keep them warm and prevent heat loss.
2. Protecting against moisture: Wet or damp conditions can be especially dangerous for young calves, as they can quickly become chilled and develop health problems. Calf jackets help to keep the calf’s body dry and prevent moisture from penetrating their skin.
3. Improving overall health: By keeping calves warm and dry, calf jackets can help to reduce the risk of respiratory infections and other health issues that can arise from exposure to cold or damp conditions.

Overall in Ireland, calf jackets are an important tool for farmers who want to ensure the health and wellbeing of their young calves, especially in colder climates or during periods of wet weather.
