Broilers supplemented with MINTREX® Cu chelated trace minerals had significantly improved feed conversion ratio (FCR) compared to copper sulfate (CuSO4) supplementation. Broilers fed MINTREX Cu showed decreased incidence of moderate to severe woody breast versus CuSO4 and tribasic copper chloride (TBCC).
A study was conducted in order to evaluate the efficacy of MINTREX Cu vs inorganic trace mineral sources in growth performance, and woody breast incidence in broilers. The study included 468 one day old Ross 308 broilers which were randomly placed in floor pens with 13 birds per pen. Each pen was assigned one of four treatments with nine replicate pens per treatment. The study lasted 42 days.
Treatments were formulated with typical U.S corn and soybean meal-based diets containing DDGS and meat and bone meal. The three-phase feeding program consisted of starter (0-14d), grower (15-28d) and finisher (29-42d) phases. All diets were pelleted with the starter diet crumbled after pelleting.
Body weight and feed consumption were measured on a per pen basis on day 0, 14, 27 and 42. Breast fillets in broilers at 42 days of age were scored for woody breast using a four-point system: 0=normal, 1=mild, 2=moderate, 3=severe.
Studies showed that when compared to inorganic trace minerals, birds supplemented with MINTREX® Cu showed improved FCR during the starter phase. Broilers fed MINTREX Cu also exhibited reduced incidence of moderate to severe woody breast.
Lower inclusion rates of MINTREX Cu can replace higher inclusion rates of TBCC or copper sulfate without compromising growth performance, while also reducing the incidence of moderate to severe woody breast.
