Goats Fattening Under an Agrosilvopastoril Production System in Oaxaca

Abstract

The agroforestry systems consider the integrated management of all production within the production unit processes and conservation practices related to the use of natural resources. From this point of view, it should be approached as a system composed by subsystems and the interactions that occur among them, in order to provide a sustainable, social, economic and ecological alternative to the traditional extensive ranching. The project objective was to evaluate the fattening of goats under an agrosilvopastoril production system established in the 2013 summer-autumn cycle, at the Technological Institute of Oaxaca Valley (ITVO). Completely randomized design with factorial arrangement evaluating three factors (age, sex and supplement) and two levels were used. 16 goats feeding with nutritional ITVO block, native grasses and guaje (Leucaena esculenta) were used. The variance analysis was made by the statistical package SAS (Statistical Analysis System) version 9.4. For the comparison of measures with Tukey test (α = 0.05) and a proximal analysis by Van Soest to obtain the quality of the forages. Weight gain related to sex was differential, males and females presented a value of 63.5±18.2 and 54.25±17.3 g day/animal not significant (p>0.05), respectively. Creole goats grazing and supplemented with a nutritional block had a weight gain of 70.5±20.3 g day/animal without supplement 47.29±18.9 g day/animal not significant (p>0.05). The greater weight gained in nutritional supplement found with block showed that the use of the same influences fattening goats.
