Efecto de un compuesto nitrogenado en el agua de bebida sobre la bioquímica sanguínea en pollos broiler.

Abstract

The present research work was carried out in an open house of the “Santa Inés” Farm located at the Faculty of Agricultural Sciences of the Technical University of Machala, El Oro province, Machala, respecting the biosecurity measures applied for this type of system. The objective of the research was to evaluate the effect of the inclusion of a nitrogen compound in the drinking water on the blood biochemistry of broiler chickens. The field study was experimental, with a population of 200 birds, in which 5 treatments were used with four experimental units, each with 10 broilers, using a completely randomized design (CRD) for their allocation. All will consume an isoproteic or isoenergetic balanced diet; control with no product, T2: 12 cc converya and 4.5 cc probiotic; T3: 24 cc converya and 9 cc probiotic per bird for 5 weeks, T4: 48 cc converya and 18 cc probiotic and T5 60 cc converya and 22.5 cc probiotic. The birds were managed according to strict safety and hygiene standards, receiving controlled feed and water in a suitable environment that included appropriate climatic conditions, good ventilation, temperature control and proper management of litter and feed. In addition, a preventive vaccination schedule was implemented, using vaccines against Gumboro and New Castle, together with their revaccination through the drinking water. The weights of the birds were recorded weekly in grams, documenting the data and procedures performed. At day 35, animals were randomly selected for slaughter, obtaining blood samples directly from the jugular vein after discarding the first stream. These samples, collected in red capped tubes and preserved on ice, were obtained from females in each experimental unit, totaling 40 samples for biochemical analysis. Variables analyzed included total cholesterol, high-density lipoproteins (HDL), triglycerides, low-density lipoproteins (LDL), very low-density lipoproteins (VLDL) and total proteins. Statistical analysis was performed using Statgraphics Centurion XV.I.®, applying an ANOVA to identify significant differences between treatments and using Fisher's multiple comparison test (LSD) with a confidence level of 95% to determine differences between means. The results reveal that the inclusion of a nitrogen compound in the drinking water of broiler chickens, at doses of 12 to 60 cc, does not affect the mentioned biochemical parameters, suggesting that the use of the product is safe within that dose range.
