Efecto de los polisacáridos sulfurados marinos en los parámetros productivos y respuesta celular en pollo de engorda

Objectives: The objective of the work was to identify a natural alternative that allows to obtain more efficient productive parameters and that in turn the immune system of the birds is more resistant to pathogens. The administration of seaweed polysaccharides has been shown to promote greater resistance to individuals under stress conditions, suggesting an immunostimulatory effect. Methodology: 582 male chickens of the Cobb genetic line were used, with one day of births which were distributed in 2 treatments with 3 repetitions of 97 birds: control treatment and treatment with polysaccharides. The polysaccharides used were of the Olmix © brand and were used at a dose of 45 g per 500 L of water on days 9, 11, 12, 19, 21, 22, 34, 36, and 37 of life. Productive parameters and cellular response were determined, which was performed by smears stained with the hayem-turk technique to later perform the count in the neubauer chamber. Samples for leukocyte and lymphocyte count were performed on days 9, 12, 19, 22, 34 and 37. Contribution: The use of polysaccharides can favor the weight gain of the broiler.
