Efectos de las enzimas digestivas en la producción de pollos de engorde.

Abstract

This research work aims to study the effects caused by digestive enzymes in the production of broilers. The bibliographic information was gathered from scientific platforms such as Scielo, Scoopus, E-book, Sciense diret, Dspace Espoch, experimental theses and digital scientific articles. It is known that the action of the enzymes in the digestive system of chickens that are in charge of degrading specific bonds, breaking cell walls, reducing nutrient losses, modifying the microflora and morphology of the intestine, providing greater availability of nutrients, reducing the anti-nutritional factors and maintaining the intestinal health. It is also known that within the characteristics of enzymes is the specificity which allows an enzyme to take care of a certain substrate and its action will depend on the environment in which it is found, since this may be a factor for its inactivation. To know the efficiency of the enzymes, several authors were analyzed regarding the following study variables: weight gain (g / day / bird), feed consumption (g / day / bird), feed conversion. For the evaluation of weight gain, within the investigations carried out, the authors defend the hypothesis that there is a greater weight gain when administering enzymes in the animal feed. Regarding feed consumption, this was influenced by the addition of digestive enzymes in the diet of broilers, thus representing a lower feed consumption. Regarding food conversion, in the research carried out, the authors maintain that there is a better food conversion when using exogenous digestive enzymes. It is concluded that the use of exogenous digestive enzymes is very important, since chickens improve its digestibility and use of nutrients contained in the diet.
