Inclusión de Botón de oro (Tithonia diversifolia) en la dieta de gallinas ponedoras de la raza Back Brown y su influencia en los parámetros productivos.

Abstract

The present investigation was developed in the municipality of Pamplona and had the objective of evaluating the feeding substitution in laying hens and how it affects the productive parameters and the feeding costs; In this research, chickens from the Isa Brown semi-heavy line were evaluated, which were divided into 4 groups, each experimental group had a percentage of inclusion of Tithonia diversifolia of 5%, 10% and 15%, respectively, and a control group. For data collection, productive variables such as egg weight, feed efficiency, yolk color, percentage of broken egg, percentage of laying were taken into account, some of these data will be taken daily and others weekly. The data was taken from the 21st week of age, thus giving an adaptation period of one week, with an experimental period of 10 weeks. A statistical analysis of variance ANOVA was performed; Production parameters were evaluated, such as the percentage of laying in which the witness group reached a percentage of 76%, in terms of the type of egg, the one that showed the most laying was the type AA of the group of 15% inclusion who threw a result of 49%, another variable studied was the amount of balanced food consumed for which the group of 15% showed a lower consumption per package of food using 2.2 thus reducing costs; On the other hand, the coloration of the yolk showed that the percentage of inclusion increased, it turned more yellow to orange, being that of T3, which had 15% inclusion of Buttercup, who showed these characteristics; When verifying the statistical analysis, it was shown that the parameters that showed a statistical difference (P <0.05) were the amount of food consumed, and the color of the egg yolk.
