              Abstract 
 
              Aim: This work was carried 
              out to study the effect of coenzyme Q10 supplementation on serum 
              calcium and phosphorus levels, tibial bone weight, bone ash, bone 
              calcium and phosphorus levels and mortality of birds due to leg 
              weakness when the broilers were maintained under high 
              environmental temperature.Materials and Methods: The trial was carried out on 216 
              Cobb400 broiler chicks and divided into four groups with nine 
              replicates and each replicate consisting of six birds. The 
              treatments include normal energy diet (NE) (as per breeder's 
              specifications) (G1), high energy (HE) (NE plus 100 kcal/kg) diet 
              without CoQ10 supplementation (G2), high energy diet supplemented 
              with CoQ10 at 20 mg/kg (G3) and high energy diet supplemented with 
              CoQ10 at 40 mg/kg (G4). The experiment was carried out when the 
              temperature humidity index (THI) ranged from 33.05 to 38.65oC for 
              a period of 42 days.
 Results: The serum calcium and phosphorus levels in the G1, 
              G2, G3 and G4 were 9.07 ± 0.22, 8.48 ± 0.10, 8.30 ± 0.10, 8.32 ± 
              0.12 and 4.90 ± 0.20, 4.06 ± 0.32, 3.96 ± 0.17, 4.02 ± 0.24, 
              respectively. The tibial bone weight (g) was 21.58 ± 1.32, 17.92 ± 
              1.90, 18.67 ± 1.30 and 17.42 ± 1.18; tibial bone Ash (%) 46.67 ± 
              2.71, 44.48 ± 2.40, 44.66 ± 3.09 and 44.62 ± 1.74; Bone calcium 
              (%) 33.57 ± 0.2, 31.27 ± 0.55, 31.50 ± 0.45 and 31.47 ± 0.83, bone 
              phosphorus (%) was 11.86 ± 0.16, 10.38 ± 0.11, 10.68 ± 0.08 and 
              10.39 ± 0.17, respectively in G1, G2, G3 and G4 groups. The serum 
              calcium and phosphorus levels were significantly higher (P<0.05) 
              in G1 over the other three groups. The tibial bone weight was not 
              altered by the energy level or the coenzyme Q10 supplementation. 
              The tibial bone calcium and phosphorus levels were significantly 
              higher in G1 than the other three groups.
 Conclusion: The supplementation of coenzyme Q10 did not 
              alter the serum and tibial bone calcium and phosphorus levels. The 
              leg abnormality associated mortality was significantly decreased 
              in G3 group when compared to the other two high energy groups.
 Keywords: bone minerals, broilers, CoQ10, temperature
