Evaluación del efecto del 25 hidroxicolecalciferol [25-(oh) d3] más la adición de minerales orgánicos sobre la producción y calidad del huevo en gallinas ponedoras Lohmann Brown

In order to determine the effect of 25 hydroxycholecalciferol plus the addition of organic minerals on egg production and quality in Lohmann Brown laying hens, in addition to studying the advantages of using 25 hydroxycholecalciferol plus the addition of organic minerals and to know the benefit-cost relationship of using them in brown laying hens in the final phase of their laying cycle, a completely randomized design was used. Sixty laying hens from 62 to 67 weeks of age were randomly distributed in three treatments with five replicates and four experimental units per replicate. The treatments were T0 (Base Diet), T1 (Base Diet plus 62g of [25-(oh) d3]) and T2 (500g of [25-(oh) d3] plus organic minerals). No dead hens or differences in feed consumption were recorded. At the end of the study, the supplementation of [25-(oh) d3] plus the addition of organic minerals did not significantly affect (p>0.05) the productive parameters of the birds such as body weight, number of marketable and unmarketable eggs, eggs per housed bird and egg weight; likewise, there was no significant difference (p>0.05) with respect to the internal and external quality of the egg; it should be emphasized that the values obtained were within the expected laboratory ranges, except for yolk pigmentation. The lowest production cost corresponds to the Base Diet ($0.0637). Regarding the cost-benefit ratio, there is a similarity between the Base Diet treatment ($1.57) and the Base Diet + [25-(oh) d3] treatment ($1.53) because the total number of eggs produced does not vary significantly.
