Abstract

Commercial broiler producers and nutritionists have questioned the performance consequences of sulfur (S) from various dietary and water sources combined in current commercial production. The combination of high-S feed ingredients, including dried distillers grains with solubles, and dietary additives that contain S, such as lysine sulfate or copper sulfate, has the potential to create high S exposure, especially when combined with high-S drinking water. The tolerance of growing broiler chicks to S was determined by supplementation of a corn-soybean-5% dried distillers grains with solubles diet with up to 1% lysine sulfate or an equal amount of S from sodium sulfide. An additional diet containing copper and zinc sulfate served as a positive control for the source of S and high-S inclusion. These diets were fed to chicks provided with normal (0.008% or 80 ppm) or high water S (0.113% or 1130 ppm). We hypothesized that the addition of S sources to a commercial diet would not reduce the performance of growing chicks given access to normal or high-S water. Data showed dietary S requirements were met and excess S was easily excreted, hence, under the experimental feeding conditions, supplementation with up to 1% additional lysine sulfate (or a similar product) did not reduce performance in comparison with chicks fed a lower S diet with access to normal or high-S water. The high-S diet from copper and zinc sulfate resulted in reduced water and feed consumption, although there were no effects on chick weight gain.
