NUNEZ-TORRES, Oscar Patricio et al. Behavior of propolis tinture on immunoglobulins in broiler chickens. J.Selva Andina Anim. Sci. [online]. 2018, vol.5, n.1, pp.33-43. ISSN 2311-2581.

The present trial was carried out in the community "El Empalme", in the Quero canton, in 240 chickens by means of necropsies to obtain the morphometry of the primary lymphoid organs performed at 31 and 51 days of age, the birds, while for the measurement of the level of immunoglobulins, 5 mL of blood was obtained at 51 days of age, from the brachial vein, then the levels were measured in a laboratory. The objetive was to evaluate the effects of a propylene tincture on immunoglobulins in broiler chickens. Three doses of propolis were extracted, which were 25 mg / kg PV, 50 mg / kg PV, and 75 mg / Kg PV. and a witness, as a standard for the measurements of the levels, it was established that a dose of 50 mg / Kg PV., of propolis improves the weight of the Bag of Fabricio, in this way helping the immune system in the chickens, since which is the best option for BIF, this being the treatment that had the greatest measure in all the parameters used, such as the mortality rate of the primary lymphoid cells (Fabric Bag, Spleen), the levels of immunoglobulins (IgG, IgM). It should be noted that the immunoglobulins only existed mathematical difference since it did not rise considerably above normal levels in birds at 51 days of age.
