Concentrados caseros para la producción avícola en Tacotalpa, Tabasco

Resumen

The purpose of this study was to formulate and evaluate the bromatological composition of three homemade mixtures on the productive performance of broiler chickens. This research was conducted at the facilities of the Universidad
Intercultural del Estado de Tabasco. Three mixtures were prepared using maize (Zea mays), beans (Phaseolus vulgaris) meals, along with forage leaves (Gliricidia sepium, Manihot esculenta and Cnidoscolus aconitifolius). Bromatological
analyses were performed in the laboratories for food chemical analysis of UNAM. The diets were provided to 48 Cobb 500® broilers during the starter, grower, and finisher phases of the fattening process. The experimental design was completely randomized, with three treatments, four replications, and four broilers per replication. The treatments were as follows: T0=100 % commercial feed, T1=100 % homemade feed and T2= a 50:50 mixture of homemade feed and commercial feed. Over six weeks, weight, feed intake, weight gain, and feed conversion ratio were recorded. Variance analysis was performed using SPSS® ver. 19. The bromatological analysis revealed that the starter, grower, and finisher formulation contained protein levels of 19.29, 15.58 and 13.25 %, respectively. During the first week, only feed intake showed significant differences among treatments. In the third week, all variables presented significant differences. However, when comparing the means, it was observed that the mixture had a performance similar to that of the commercial feed during the entire experiment. These results suggest that homemade feed is a viable alternative for broiler chicken feeding and their use could be further considered for native chicken breeds.
