Utilización de residuos agroindustriales como suplemento dietario para pollos parrilleros (Gallus gallus)

Abstract

The fruit and vegetable industries in the Río Negro Valley area devoted to the production of concentrated juices, ciders, and pulps generate large volumes of bagasse. Numerous studies have shown that fungi of the genus Pleurotus are capable of developing on lignocellulosic substrates, producing edible mushrooms, and converting the biodegraded substrates into an enriched fodder called pleurotin. The chemical composition of pleurotin, which includes fibers, proteins, and small concentrations of anti-physiological compounds, contribute to its high digestibility value, making it possible to use it for animal feed. In this work, the effect of intermittent supplementation with pleurotin in the diet of broiler chickens on productive parameters was evaluated. Contrasting with that obtained from a commercial diet, daily weight gain (GDP) and total (GTP), final live weight (PV), and clean weight (PL) were evaluated, as well as feed consumption (CA). , feed efficiency (EA), and mortality. Breeding conditions and biosecurity (feeding, nearly vaccination, temperature, light, aeration, hygiene, and sanitization of the environment) were adequate since the animal mortality was nil. Pleurotin was accepted by the animals. The final weight of the chickens, as well as their weight gain and EA, are similar between the two batches, allowing pleurotin to be accepted in intermittent supply as a supplement in the diet, highlighting that it would cover a double purpose: on the one hand, introducing a by-product of the region's fruit and vegetable industry in a different production cycle and, on the other, could constitute an economic advantage for poultry producers, provided that it is obtained at a lower price than the commercial balance, to replace a part of it in the chicken diet.
