The objective of the present work was know the botanical composition of the goat's intake in natural pasture, between them years 2011-2013, and the quality forage of them species that greater participation presented along them cycles vegetative covered between 2013-2015, in the Plateau Central of Mendoza. This was evaluated in 54 Criollo adult goats by Fecal Micro-histology method in Regrowth, Flowering and vegetative Latency phases. Forage quality of species with greater participation was assessed by levels of crude protein, Official Methods of Analices (AOAC, 1980), Neutral Detergent Fiber, Acid Detergent Fiber (Van Soest, Robertson and Lewis, 1991) and Digestibility In Vitro Dry Matter (Barnes and Marten, 1980). The media and standard desviation was studied by ANAVA and Tukey test. The bushes were the most consumed species, 53.03% on Regrowth, 64.7%, in Florewing and 74.2% in Latency, highlighting species Lycium sp., Schinus sp. and Prosopis sp, as which participated in the three phenological moments of the natural pasture, with levels of intake upper to the 8% in, each moment
Resúmen
El objetivo del presente trabajo fue conocer la composición botánica de la ingesta caprina en pastizal natural entre los años 2011-2013 y la calidad forrajera de las especies que mayor participación presentaron a lo largo de los ciclos vegetativos comprendidos entre 2013-2015, en la Meseta Central de Mendoza. Para ello se evaluó por micro-histología de heces de 54 cabras adultas tipo criollo en las fases Rebrote, Floración y Reposo vegetativo. La calidad forrajera de las especies con mayor participación se analizó por niveles de proteína bruta (AOAC, 1980), fibra detergente neutro, fibra detergente ácido (Van Soest et al., 1991) y digestibilidad in vitro materia seca (Barnes y Marten, 1980). Las medias y desvíos estándar se estudiaron por ANAVA y test de Tukey. Los arbustos fueron las especies más consumidas, 53,03% en Rebrote; 64,7% en Floración, y 74,2% en Latencia, destacando las especies Lycium sp., Schinus sp. y Prosopis sp, como las que participaron en los tres momentos fenológicos del pastizal natural, con niveles de ingesta superior a 8% en cada momento
