- Effect of coated calcium feeding on growth performance, carcass traits, immunity, blood biochemistry and tibial bone morphometry in commercial broiler chicken
The research investigated the impact of replacing conventional limestone with coated calcium on broiler performance, immunity, blood biochemistry, and bone development.
A total of 416 broilers were divided into four treatment groups receiving 0%, 10%, 20%, or 30% substitution of limestone with coated calcium over a 42-day period.
The 30% substitution group exhibited significantly improved body weight gain, feed conversion ratio, and carcass yield. Moreover, this group showed enhanced humoral and
cell-mediated immunity, greater immune organ weights, and improved tibial bone characteristics (weight, length, and diameter).
Serum and bone concentrations of calcium and phosphorus increased, while excretion of these minerals was reduced.
The findings indicate that replacing 30% of traditional calcium sources with coated calcium is an effective nutritional strategy to improve both productivity and skeletal health in broilers.
