Promotores de crecimiento naturales en la producción de pollos broiler

Abstract

The objective of the present bibliographic review project was to study the different natural growth promoters for Broiler production, making a compilation of bibliographic information available in Dspace ESPOCH, SciELO, Google Scholar, Animal Science, for the following treatments such as the extract of chili, purple onion, garlic and chamomile in combination with chili pepper. When analyzing the different plant extracts, the best results were recorded with the natural growth promoter based on the extract of chili by adding 2% in the diet for broiler chickens, since it is achieved a greater final weight 3.08kg, weight gain 3.04kg, yield to the channel 78.12% and food conversion 1.35; this guarantees us the best economic return to own a broiler farm, since the chili contains capsaicin therefore has the ability of antibiotics to inhibit microorganisms of the digestive tract. The economic analysis determined the highest profitability by incorporating 2% of the chili extract, since the benefit/cost ratio was 1.31, that is to say that for each dollar invested, a profit of 31% is expected. So it is concluded that chili pepper extract can be used as an ingredient in the feeding of Broiler Chickens due to its nutritional components such as protein, lipids, vitamins, minerals that improve the productive parameters in chickens obtaining a low commercial cost producto. It is recommended to continue investigating the current and other natural growth promoters in chickens and other zootechnical species to determine the best level of extracts.
