What is the FCR in broilers and how do I improve feed conversion?

FCR, the feed conversion ratio, is the amount of feed used to produce one unit of body weight, so a lower FCR means the bird turns feed into meat more efficiently and your cost per bird is lower. Since feed is the biggest cost in broiler farming, even small improvements in FCR add up. To improve it, use good quality balanced stage feeds, avoid feed wastage with proper feeders and correct feeder height, and give clean water at all times since water intake drives feed intake. Keep the shed at a comfortable temperature with good ventilation, because heat stress and high ammonia hurt growth, and follow the vaccination and disease control plan so birds are not fighting illness. Healthy, comfortable birds on good feed and clean water give the best FCR.
