Efecto de la restricción alimenticia en el control de enfermedades metabólicas en pollos de la Línea Cobb 500 en la Finca Punzara de la Universidad Nacional de Loja

This research entitled " EFFECT OF FOOD RESTRICTION ON METABOLIC CONTROL IN CHICKENS OF COBB 500 ONLINE AT THE NATIONAL UNIVERSITY prick LOJA FINCA " aimed to help improve production systems broiler in the Hoya de Loja, by evaluating programs that allow food restriction reduce the incidence of metabolic disease and increase production levels . Affection for four treatments with three replicates per treatment were formed , the experimental unit was formed of 25 chickens. Completely Randomized Design was used. The following treatments were evaluated: The first treatment (control) according to the food table manual Cobb 500 line is provided , in the two treatment restricted to 5% of food from the eighth to the twenty- eighth day treatment three restricted to 10% of food from the eighth to the twenty-eighth and finally a four day treatment with a restriction of 15% according to table Cobb 500 manual online. The results obtained in the different variables are: Increased consumption of food he got treatment 1 (control) to 4690.6 g, then Treatment 2 with 4529.2 g and finally the treatment 4 with 4352.2 g . As for weight gain which reached the group was the first treatment 1 (control) with increased weight of 2658.87 g, followed by Treatment 2 with an increase in weight of 2632.51 g and finally the treatment 4 with a weight increase of 2485.74 g . The best feed conversion the received Treatment 2 with a feed conversion 1.72:1 after Treatment 3 with a feed conversion of 1.74:1 and finally Treatment 1 (control) at a feed conversion of 1.77:1. The lowest mortality scored Treatment 2 with a mortality of 2% followed by treatment 4 with a mortality rate of 3%, and finally the Treatment 3 and Treatment 1 (control) with a mortality of 5 %. American Best Efficiency Factor Treatment 2 as achieving an American efficiency factor of 185.42, then the treatment 3 with an efficiency factor of 182.64 American Treatment 4 and finally an efficiency factor American 170.27. In terms of profitability, the most profitable group proved Treatment 2 with a profit of 45%, then the Treatment 3 with 32% and finally treatment with lower performance proved Treatment 4 with 18%. The results allow us to deduce that treatment two (Restriction 5%) obtained the best results meeting expectations of research.
