Abstract
In order to evaluate the effect of 25-OH-D3 on productive performance of broilers and bone mineralization, an experiment in which 10,000 newly born Cobb mixed was used. The animals were divided into two groups: experimental received 25-OH-D3 at a dose of 50 mg/liter and a control group (0 mg/liter). Weight gain and European Production Efficiency Factor (EPEF) were higher (P < 0.05) for chickens that received 25-OH-D3. Mortality was lower (P < 0.05) for the group receiving 25-OH-D3. However feed conversion rate (FCR) and feed intake showed no significant difference between treatments. The amount of calcium in tibia was higher in the experimental group (P < 0.05). Based on the results obtained, it is concluded that the use of 25-OH-D3 improves production performance and bone mineral status broiler.

The day-to-day poultry industry seeks to satisfy the consumption of animal protein demand growing human populations around the world to meet their nutritional requirements
This study aims to evaluate the effect of oral supplementation of 25-OH-D3 as a source of vitamin D highly available to promote the proper development of the bones of the bird broiler
With respect to calcium content, significant effects between treatments (P < 0.05). The content of this element was higher in the group receiving 25-OH-D3 (19.25 ± 1.23) versus the control group (17.96 ± 1.30)
Summary
The day-to-day poultry industry seeks to satisfy the consumption of animal protein demand growing human populations around the world to meet their nutritional requirements. These diseases are those affecting the skeletal system and are linked to nutritional factors such as levels of calcium, phosphorus, vitamin D and others [3]. Laying hens they can be affected after presenting deformities poor nutrition level of the keel bone [4] and increasing the brittleness of the shell [5], problems arise in Turkeys ossification especially during growth [6]. That nutrition influences the expression of the maximum production potential of the bird by reducing the occurrence of bone diseases, preventing injury on performance
