Safety for Supplementing Heat to Livestock
When it becomes necessary to provide supplemental heat to livestock, management of the barn and heat sources is important to ensure building and livestock safety.
While most livestock can tolerate colder temperatures well, there are times when providing supplemental heat may be necessary to promote their health and welfare. Newborn animals entering the world in the middle of the coldest months is just one example. While there are many ways to supplement heat, mindful steps need to be taken to ensure that those heat sources are both effective and safe.
Heat lamps are one of the most commonly used heat sources due to their low cost and simplicity. However, they are a major cause of barn fires, making design selection crucial for safety. Lamps should have solid ceramic bases, thick, intact cords, and a protective covering around the bulb. The protective covering, which is made of a wire or plastic, keeps the bulb from touching the ground should the heat lamp fall, and reduces the risk of animals potentially breaking the bulb.
Other options for heating include radiant plates, heat pads, and gas heaters, though these should be rated for barn use, firmly affixed to the wall, ceiling, or floor, and kept out of reach of livestock. Portable space heaters are not a good idea, since they can be knocked over by animals. Ideally, heaters should have an automatic shut-off in the case they are tipped.
A few general rules can help promote safe heating. Dust accumulations on any heater should be regularly removed. If possible, heaters should be kept at least two feet away from flammable items such as wood, bedding, fertilizer, pesticides, or cobwebs. Any device should be plugged directly into the wall; using extension cords can increase the risk of fire and malfunctions.
Commercial-sized (5 - 10 pound) fire extinguishers should be kept within easy reach in and around farm buildings. An ABC extinguisher is best, since it can tackle the various fire classes that can start within a barn. The installation of fire alarms, especially in areas where supplemental heat is used, can provide an advance notice of a fire. This can result in quicker response times, saving a barn or livestock. Having an emergency plan in place in the case of a fire including a list of contacts and evacuation plan is advantageous should an adverse event happen.
Supplemental heat is a tool that can be used to maintain the health and comfort of some newborn animals such as chicks, piglets, kids, and lambs; smaller livestock like rabbits, which may be more sensitive to cold; and individuals in poor health which cannot make enough of their own body heat. While heating a livestock area can present risks, they can be mitigated by following the considerations above.

Upcoming Events
Silvopasture on a Shoestring
October 7, 2025
Franklinville, NY
Join Joshua Greene, Director of Education at Trees For Graziers, Jonathan Bates, Statewide Agroforestry Educator, and Lynn Bliven, owner of Wild Geese Farm for a full day training event that will include classroom and hands-on sessions. The focus will be on DIY silvopasture projects on small grazing farms. We will address the practical considerations of tree establishment, protection, and maintenance while learning how silvopasture can help address your farm's resource concerns and enhance livestock grazing.
Optimizing the Economic Return of Pasture-Raised Slow-Growth and Conventional Broilers - Webinar

November 13, 2025
: Optimizing the Economic Return of Pasture-Raised Slow-Growth and Conventional Broilers - Webinar
Over the past three years, Cornell Cooperative Extension has worked with nearly 40 small farmers across NYS to gather information on the true costs of raising broilers (meat chickens) on pasture. This presentation is a summary of the findings of this research project.
Fecal Egg Count Mobile Workshop - East Aurora
October 21, 2025 : Fecal Egg Count Mobile Workshop - East Aurora
East Aurora, NY
This workshop will explain why regularly testing fecal egg counts can help you with understanding your animals' parasite loads and dewormer resistance. Attendees have the opportunity to prepare and evaluate fresh fecal samples under the microscope and practice interpretations.
