Organic Swine Feed

Nature’s Trail organic swine feeding program is formulated with extensive cooperation from Provimi, an international leader in swine nutrition. Using Provimi’s vast research and knowledge base, Nature’s Trail has developed a swine feeding program to assist farmers in optimizing performance while working in harmony with organic principles that restrict use of antibiotics and certain other feed ingredients. Our goal is to provide organic swine producers with high quality, palatable feed that promotes healthy growth, efficient weight gain, and good tasting meat at an affordable cost.

Tips for Care & Handling of Pigs

Organic management for pigs focuses on prevention of health problems. Provide good quality feed, fresh air, plenty of fresh water, rotation of pasture, clean bedding, and shelter from the elements. Overcrowding can result in fighting and injury. Providing something to keep them occupied can also help prevent fighting. In confined housing during cold weather, deep bedding will help with the retention of body heat. Clean pens frequently. Pigs are naturally curious but can be easily trained to an electric fence. Use two wires at nose and shoulder height. Adults can usually be contained with one wire. Be sure barn and fencing is secure. Pigs cannot sweat. In hot weather, provide fans for airflow. If your pigs are on pasture, they should have shade and an adequate place to wallow. Sprinklers can also be used to keep them cool. Since pigs are not ruminants, roughage in the diet should be limited.

Intestinal parasites are a major concern for organic hog producers. Use of an approved dewormer is highly recommended. Keep areas where pigs are confined cleaned out and rotate pasture often to reduce exposure to parasites.
