As broiler breeder hens age, they often experience a decline in bone mineralization and calcium absorption, especially during the later stages of egg production. This issue not only affects hens’ health, making them more prone to conditions like osteoporosis, but it also impacts quality their offspring. To tackle this problem, our study explores whether supplementing these with combination vitamins D 3 C could help improve health overall biochemical balance, both for progeny. The goal research was evaluate effects high doses vitamin , without added C, on key blood parameters aging In experiment, 240 24 roosters from Ross 308 strain, aged between 49 61 weeks, were used, two-way ANOVA (2 × 2) design applied. involved two levels (3,500 IU 5,500 IU) (0 150 mg/kg), six replications 10 one rooster per group. At end study, samples collected offspring analysis, tibia bones taken ash content assessment. findings showed that supplementation significantly lowered cholesterol, alkaline phosphatase (ALP), parathyroid hormone (PTH) ( P < 0.05), while boosting calcium, 25-hydroxycholecalciferol (25(OH)D ), 1,25-dihydroxycholecalciferol (1,25(OH) 2 ) 0.05). Higher improved strength, resistance, bones, increased carcasses Adding mg/kg diet had positive effect, reducing ALP, PTH, enhancing plasma total antioxidant capacity, active form Vitamin strengthened tibial PTH Interestingly, combining elevated resulted even greater improvements strength conclusion, giving mg along leads substantial structural integrity boosts
