IntelliBond® can improve carcass weight

30 May 2017

A study performed in Spain found that birds yielded larger live and carcass weights and a higher percentage of breast meat when fed hydroxy trace minerals as compared to broilers fed inorganic trace minerals.​

Hydroxy trace minerals can improve the bird's value

Over the past 20 years, numerous studies conducted globally to evaluate various forms of supplemental copper and zinc in broiler diets have confirmed the ability of these important trace minerals to improve carcass weights, yield and quality. More specifically, hydroxy trace minerals have been shown to be able to improve the value of each bird over inorganic sources of trace minerals.

In 2016, a study conducted at an experimental facility in Spain measured the results of hydroxy trace mineral sources of copper and zinc versus inorganic trace minerals (sulphates) when fed at nutritional levels.

Trials showing the results in broilers

Researchers allocated a total of 28 pens of 44 birds each to two treatments. During 35 days, both treatment groups were fed either 80 ppm copper and zinc as hydroxy trace minerals -Selko IntelliBond C and Selko IntelliBond Z - or in the form of sulphates. Carcass traits were assessed at a rate of 2 birds per pen.

At the end of the study, researchers found numerical improvements in the broilers fed hydroxy trace minerals over those fed inorganics. Birds in the hydroxy trace mineral programme had heavier live weights (7.4%) and heavier carcass weights (7.7%) compared to sulphate-fed broilers. Hydroxy trace minerals also contributed to an increased breast meat percentage (16.1%) compared to birds fed inorganic trace minerals (15.3%).

The data indicates that changing the source of trace minerals from inorganic sources to hydroxy trace minerals in the diet of broilers may have the ability to improve carcass traits such as weight and breast meat yield.​


  • Birds fed an IntelliBond® trace mineral programme were heavier at slaughter and had heavier carcass weights compared to inorganic trace mineral fed birds
  • Breast meat yield was greater in birds fed IntelliBond compared to birds fed inorganic trace minerals
