Abstract: The Ca, K, Mg, Na and P contents were determined, seasonally
during 2 consecutive years in leaves of native browse plants such as Castela
erecta Turp sp. Texana (Torr & A. Gray) Cronquist (Simaroubaceae),
Celtis pallida Torr. (Ulmaceae), Forestiera angustifolia Torr. (Oleaceae),
Lantana macropoda Torr. (Verbenaceae) and Zanthoxylum fagara (L.)
Sarg (Rutaceae) that were collected from August 2004 to May 2006 in a semiarid
and subtropical area of the State of Nuevo Leon, Mexico at three county (Los
Ramones, China and Linares) sites which are grouped under a similar climatic
pattern. Mineral contents were measured using an atomic absorption spectrophotometer
with exception of P content that was estimated using a colorimeter. All minerals
in all species were significantly different among years, sites and seasons and
interactions were also significant. In general, plants at Linares site which
historically registered the highest rainfall had higher mineral content followed
by Los Ramones and China. Moreover, during the 2nd year, all plants species
showed higher mineral content than the 1st year. Furthermore, during the Summer
session, all plants species had higher mineral content followed by Autumn, Winter
and Spring. Regardless of spatio-temporal differences, all plant species had
suitable levels of Ca, Mg and K to satisfy range domestic and wild ruminant
requirements. In contrast, P and Na contents showed marginal inadequacies in
some seasons throughout the year. Seasonal variations in minerals could be associated
to climatic conditions like excessive irradiance levels during Summer and extreme
low temperatures in Winter and rainfall events.
