Lack of Food & Water
If you own livestock or companion animals you must provide food that is suitable in quality and quantity appropriate for the species, and a reliable source of water. It is not acceptable to expect or allow an owned animal to fend for itself.
Animals that live outside in winter require additional food to stay warm and can lose body condition very quickly if increased rations are not provided.
A horse pawing in the snow for food is not an indication that the animal is starving; pawing is a common way for horses to access grass under the snow during winter months. It is important to note that horses will eat more, and require additional feed, just to stay warm during colder temperatures.
As horses are grazers, grazing up to 18 hours a day, they expend a great deal of energy on this activity. Winter grass, however, often lacks the nutritional quality that spring and summer pastures offer, and supplemental feeding of hay may be necessary. It is therefore highly recommended horse owners get their feed tested to ensure it meets the nutritional requirements for their animals.
Horses do have the ability to consume snow as a water source in the winter, but it is not ideal. Horses require approximately 40 litres (10 gallons) of water a day, and ten times that amount if their water source is in the form of snow. A liquid water supply is a critical part of keeping horses healthy in the winter. Further, it is important to note feed in the form of alfalfa cubes and pellets hold very little moisture and lead to a need for increased water.
Cattle, like most livestock, require increased food in winter in order to stay warm. The feed requirements of cattle change when the temperature reaches -20 or colder, and an extra two pounds of grain a day per animal is required. At -30, the feed requirements increase again by another two pounds of grain per head. These rations will only help the cattle maintain their weight; a cow that is not getting additional feed can lose one to three pounds a day on the bitterly cold days.
