RESUMEN El ácido orgánico mejora los parámetros productivos y la respuesta a tratamientos. Con el objetivo de evaluar el uso de ácidos orgánicos en las ponedoras de la línea Hy-Line para determinar el efecto en los parámetros productivos y la calidad del agua en etapa de crianza de la semana 10 hasta la semana 16. Se realizó una investigación utilizando un diseño completamente al azar, donde se utilizaron cuatro tratamientos y cuatro réplicas con 20 unidades cada uno, denominado T0 (testigo), T1, T2 y T3; administrando la mezcla de ácidos orgánicos en la dosis establecida para cada tratamiento 0,5 cc; 1 cc y 1,5 cc por litro de agua. Se evaluaron variables como peso inicial del pollo, peso por semana del pollo, consumo de alimento, consumo de agua y mortalidad. Así mismo, se realizó un análisis físico-químico: pH del agua, cloro residual, temperatura y dureza. Se obtuvieron parámetros productivos superiores (p=<0.05) en comparación con el grupo control. Los mejores resultados en peso corporal se obtuvieron en el T3 con 1385,50g. De la misma manera, el T3 logro obtener un mejor resultado en el consumo de agua durante todas las semanas, excepto en la catorce que fue el T1 quien obtuvo un mejor promedio. En cuanto a los análisis físico-químicos el T1 tuvo un mejor pH de 3,29; cloro libre: 0,17mg/l y dureza residual: 7,64mg/l; se concluye que el mejor resultado en parámetros productivos fue el T3, mientras que en el análisis físico químico el T1 obtuvo mejoras significativas. | ABSTRACT The organic acid improves the productive parameters and the response to treatments. With the aim of evaluating the use of organic acids in the layers of the Hy-Line line to determine the effect on the productive parameters and the quality of the water in the rearing stage from week 10 to week 16. An investigation was carried out using a completely randomized design, where four treatments and four replications with 20 units each were used, called T0 (control), T1, T2 and T3; administering the mixture of organic acids in the dose established for each treatment 0.5 cc; 1 cc and 1.5 cc per liter of water. Variables such as initial chicken weight, chicken weight per week, feed consumption, water consumption and mortality were evaluated. Likewise, a physical-chemical analysis was carried out: pH of the water, residual chlorine, temperature and hardness. Higher productive parameters were obtained (p = <0.05) compared to the control group. The best results in body weight were obtained in T3 with 1385.50g. In the same way, T3 managed to obtain a better result in the consumption of water during all the weeks, except in the fourteen that it was T1 who obtained a better average. Regarding the physical-chemical analysis, T1 had a better pH of 3.29; free chlorine: 0.17mg / l and residual hardness: 7.64mg / l; It is concluded that the best result in productive parameters was T3, while in the physical-chemical analysis, T1 obtained significant improvements.

The availability of different mineral waters, some with indications of therapeutic properties, makes it necessary to investigate their interaction with nutritional habits. Objective: To analyze the nutritional profile before and after 10 days of ingestion of hypothermic water enriched with minerals in hypertensive patients. Materials and Methods: Fifteen hypertensive adults (73% women), 47.9±7.7 years old, were randomly divided into a control group (CG; n=7) and an experimental group (EG; n=8). For 10 days, subjects ingested hypothermic mineral-enriched water or placebo mineral water, with an amount established at 75% of: 1500ml + 20ml * body weight. Participants were instructed to maintain their eating habits. Macro and micronutrients were calculated by the DietPro® 5i software with the information obtained from the 24-hour recalls applied before and after the ingestion of mineral water. Results: For both groups, there were no significant differences between the macro and micronutrients of the diet assessed before and after the intervention. When compared pre- and post-intervention, there were also no differences between them, except for fiber where the amount consumed by the CG in the post-intervention was greater than that consumed by the EG (p=0.034). There was a trend towards an association between caloric intake and body weight at the beginning of the intervention (p=0.071). Conclusion: There was no change in relation to diet before and after 10 days of ingestion of hypothermal water enriched with minerals, suggesting that consumption of this type of water does not interfere with the dietary pattern. However, studies involving a greater number of participants and a longer period of consumption are necessary.
