Abstract
Este estudio de investigación tuvo como objetivo evaluar el efecto de la betaina en dietas de gallinas ponedoras en la etapa de postura sobre los parámetros productivos. Se evaluaron 384 aves, en un sistema de cría en jaulas, de 65 hasta las 70 semanas de edad, asignadas de manera aleatoria a tres tratamientos con cuatro repeticiones. Cada jaula constó de 32 gallinas y se utilizaron 4 jaulas para formar una unidad experimental, teniendo un total de 12 jaulas experimentales, para cada tratamiento que constó de 128 aves. Los tratamientos experimentales fueron los siguientes: T0, con una dieta control sin betaina; T1, con una dieta que incluía 50% de betaína (representa el 0.015% de la dieta total), sin colina; y T2, con una dieta con 100% de betaína (representa el 0.030% de la dieta total), con colina y 25% menos de DL metionina. Para analizar se utilizó el ANOVA, y comparar los promedios y determinar la significancia se empleó la prueba de Tukey con un nivel de confianza del 5%. Los resultados obtenidos en el porcentaje de postura fueron de 82.33%, 86.65% y 88.05% para los tratamientos T0, T1 y T2, y sobre peso de huevo y masa de huevo se obtuvieron 62.73g y 62.83g para tratamiento T0, 63.13g y 63.53g Tratamiento T1 y 63.60, 63.78g para tratamiento T2, y la Uniformidad de peso obtenida fue de 62.83g, 63.53g y 63.78g para tratamientos T0, T1 y T2 respectivamente. No hubo mortalidad. En conclusión, la inclusión de 100% de betaina y 25% menos de DL metionina (T2), en dietas de gallinas ponedoras de 65 a 70 semanas de edad, mejora el porcentaje de producción, peso de huevo y masa de huevo, así mismo se obtiene mejor uniformidad del lote, de igual forma con la adición de 50% de betaina y cloruro de colina (T1), se tuvieron diferencias significativas al final de la investigación en comparación con la dieta control.
This research study aimed to evaluate the effect of betaine in diets of laying hens in the laying stage on productive parameters. 384 birds were evaluated in a cage breeding system, from 65 to 70 weeks of age, randomly assigned to three treatments with four repetitions. Each cage consists of 8 hens and 4 cages were used to form 1 experimental unit, having a total of 12 experimental cages, for each treatment it consists of 128 birds. The experimental treatments were the following: T0, with a control diet without betaine; T1, with a diet that included 50% of betaine (It represents 0.015% of the total diet), without choline; and T2, with a diet with 100% of betaine (It represents 0.030% of the total diet), with choline and 25% less Dl methionine. To analyze, ANOVA was used, and to compare the averages and determine significance, the Tukey test was used with a confidence level of 5%. The results obtained in the percentage of laying were 82.33%, 86.65% and 88.05% for treatments T0, T1 and T2, and egg weight and egg mass were obtained 62.73g and 62.83g for treatment T0, 63.13g and 63.53g. Treatment T1 and 63.60, 63.78g for treatment T2, and the weight uniformity obtained was 62.83, 63.53g and 63.78g for treatments T0, T1 and T2. There was no mortality. In conclusion, the inclusion of 100% of betaine and 25% less of Dl methionine (T2), in diets of laying hens from 65 to 70 weeks of age, improves the percentage of production, egg weight and egg mass, as well as better uniformity of the batch, likewise the addition of 50% of betaine and choline chloride (T1), had a significant difference at the end of the research obtained in comparison with the control diet
