Study of the effect of microemulsions from Zingiber officinale extracts on broiler chicken production

Due to the transcendent use of phytochemical extracts as feed additives for different animals, easy access to them, low costs and several studies that demonstrate their performance as growth promoters, this study focuses on the use of microemulsions as a carrier and release system of active ingredients, which will boost the effectiveness of Zingiber Officinale extract in broiler chickens. Different characterization methods were key tools for the development and study of the resulting product (microemulsion) and its components. Fourier transform infrared spectrometry, together with phytochemistry, provides us with a spectral signature supported by the organoleptic study of the extract. Dynamic Light Scattering together with a rheological study provides us with information on particle size, molecular behavior, viscosity, plasticity, elasticity and spillage of the product. To arrive at the final formulation of 18.16% surfactant, 34.91% organic phase and 46.93% aqueous extract phase, several component graduation tests were performed, as well as the use of several surfactants: hexadecyltrimethylammonium brom, Sodium Lauryl Sulfat, and SPAN 60, yolk lecithin and food grade soy lecithin. The product was administered to the sample of 200 chickens from day 8 to 42, when they were ready for consumption. A statistical study was carried out to show if the effectiveness is significant, reaching the conclusion that the additional administration of this growth promoter does favor broiler chick weight gain.
