Utilización de diferentes niveles de un protector hepático en la alimentación de aves Lohmann Brown durante la segunda etapa de producción

Abstract

The objective of this study was to evaluate the effect of the use of a liver protector in doses of 0.5,1.0 1.5 Kg/Tn versus a control, when added to the feed of Lohmann Brown birds during the second stage of production. The research was carried out at El Sol Poultry Farm located in Chimborazo Province, using 200 hens of 65 weeks of age, distributed under a completely randomized design, where 4 treatments with 10 replicates were elaborated, each experimental unit was composed of 5 animals. The variables investigated were initial live weight, final live weight, weight gain, feed intake, egg weight, egg production, feed conversion and mortality. The results obtained were subjected to an analysis of variance (ADEVA) and a separation of means according to Tukey (P ≤ 0.05); no statistically significant differences were shown, but numerical differences were obtained, being the use of balanced + liver protector 0.5 kg/Tn the ideal treatment with a B/C of 1.10 USD, having been the result of a higher number of eggs produced. It was concluded that the use of the hepatoprotector at a dose of 0.5 kg/Tn does have positive effects on the productive behavior of the bird, improving the health and profitability of the animals in the experimental word. The application of hepatoprotector is recommended during all stages of hen production.
