(2024-08) Jima Jiménez, Álvaro Fernando; Guerrero López, Jorge Ricardo
The objective of this study was to evaluate the microbial preparation on the productive indices in laying hens, being evaluated 0.1%, 0.2% and 0.3%, and its effects on the productive indices and the cost/benefit relationship of the different treatments. Four different treatments were evaluated, including a control with 0% microbial preparation. For this research work, a completely randomized statistical design was carried out, which consists of ten repetitions for each treatment applied and five birds per repetition, that is, 50 experimental units adding a total of 200 laying hens of the Lohmann Brown – Classic line for research. The analysis of the means was performed using Tukey's statistical test at 5% reliability. Nine productive indices were evaluated and it was concluded that the different percentages of microbial preparation added to the birds' diet, it was determined that the best treatment was T2 and T3, for the variable egg weight with an addition of microbial preparation at 0.2 and 0. .3%, respectively, where a weight of 63.21g and 63.28g was achieved, showing highly significant differences compared to the T1 treatment (0.1%) with a weight of (61.52g) and the control T0 (0 %) obtained a minimum weight of (60.77g). Regarding the remaining variables, there are no statistically significant differences between the treatments. In cost/benefit ratio, T2 has a greater value of 1.07 points.
