Effects of 25‐hydroxycholecalciferol with two D3 vitamin levels on production and immunity parameters in broiler chickens

Summary This study was performed in Ross 308 chickens aged 1–21 days and aimed to evaluate whether the addition of 25‐hydroxycholecalciferol (25(OH)D3) to broiler chicken diets affects their growth performance and immunity. A completely random 2 × 2 factorial arrangement was used with two levels of...

Description
Summary:Summary This study was performed in Ross 308 chickens aged 1–21 days and aimed to evaluate whether the addition of 25‐hydroxycholecalciferol (25(OH)D3) to broiler chicken diets affects their growth performance and immunity. A completely random 2 × 2 factorial arrangement was used with two levels of vitamin D3 and the absence or presence of 25(OH)D3, corresponding to four treatments based on sorghum + soya bean diets: (i) 200 IU of vitamin D3/kg of feed (Diet 1) (NRC, ), (ii) Diet 1 + 69 μg of 25(OH)D3/kg of feed (Diet 2), (iii) 5,000 IU of vitamin D3/kg of feed (Diet 3) and (iv) Diet 3 + 69 μg of 25(OH)D3/kg of feed (Diet 4). Each treatment was conducted with six replicates of 10 chickens each. Water and feed was supplied ad libitum. The results showed significantly increased growth and tibia ash (p
