Bienestar productivo en el comportamiento de pollos camperos con tres tipos de densidades.

Abstract

The objective of this research was to evaluate the productive welfare in the behavior of farm pigs with three types of densities, for which 60 experimental units were evaluated in a completely randomized design with 4 treatments: T1 (10 chickens/m 2), T2 (12 chickens/m2) and T3 (14 chickens/m2); Weight gain, final weight, feed conversion, survival, animal welfare and economic analysis were measured. The results establish a positive effect on the productive behavior of the producer pigs in weight gain (p<0.05) with the best treatments in T2 (12 chickens/m2) and T3 (14 chickens/m2) with 2.34 and 2.32 kg and feed conversion 2.47 and 2.34, respectively; for the final weight it was higher than T2 (12 chickens/m2) with 2.35 kg. The highest survival (100%) was obtained in the treatments with the lowest population density of chickens/m2, T1 (10 chickens/m2) and T2 (12 chickens/m2); it was established that all animal welfare parameters of the chicken breeder increased negatively as the population densities of chickens/m2 increased, with the lowest welfare being T3 (14 chickens/m2). T2 was established (12 urns/m2), although it had the highest rate of marginal return (42.69%) as it was the most profitable from the economic point of view.
