ABSTRACT
ABSTRACT This study was conducted to determine the monthly composition of the minerals Ca, P, K, Mg, Cu, Fe, Mn and Zn in five shrub species that are consumed by small ruminants in the semi-arid regions of northeastern Mexico. Leaves samples of shrub species; Celtis pallida, Croton suaveolens, Forestiera angustifolia, Guaiacum angustifolium and Parkinsonia aculeata were randomly collected during twelve consecutive months from July 2018 to June 2019 in two sites, located in Linares and Los Ramones counties, in the state of Nuevo Leon, Mexico. Mineral content was analyzed using an atomic absorption spectrophotometer, while phosphorus was measured by the colorimetry method. The Linares county showed the highest content of macro- and micro-minerals. Among species, C. pallida showed the highest values of macro-minerals and P. aculeata content of micro-minerals was highest. Ca (total mean = 40.0 g kg-1 DM), K (15.4 g kg-1), Mg (3.7 g kg-1), Fe (87.2 mg kg-1), Mn (35.5 mg kg-1) were available in adequate quantities, while P (1.3 g kg-1 DM), Cu (6.4 mg kg-1) and Zn (17.7 mg kg-1) were found deficient. Shrub species in this study can be considered as a good source of Ca, K, Mg, Fe and Mn except in C. suaveolens. However, P, Cu and Zn must be supplemented.
RESUMO
RESUMO O presente estudo foi realizado com o intuito de determinar os teores dos minerais Ca, P, K, Mg, Cu, Fe, Mn e Zn, ao longo do ano, em cinco espécies de arbustos consumidas por pequenos ruminantes nas regiões semiáridas do nordeste do México. Amostras de folhas de espécies arbustivas; Celtis pallida, Croton suaveolens, Forestiera angustifolia, Guaiacum angustifolium e Parkinsonia aculeata foram coletadas aleatoriamente durante doze meses consecutivos, de Julho de 2018 a Junho de 2019, em dois locais, nos municípios de Linares e Los Ramones, no estado de Nuevo Leon, México. O conteúdo mineral foi analisado através de um espectrofotômetro de absorção atômica, enquanto o fósforo foi medido pelo método da colorimetria. O município de Linares apresentou o maior conteúdo de macro e microminerais. Entre as espécies, C. pallida apresentou os maiores valores de macrominerais, enquanto o teor de microminerais foi maior na P. aculeata. Ca (média = 40.0 g kg-1 MS), K (15.4 g kg-1), Mg (3.7 g kg-1), Fe (87.2 mg kg-1), Mn (35.5 mg kg-1) estavam disponíveis em quantidades adequadas, enquanto P (1.3 g kg-1 MS), Cu (6.4 mg kg-1) e Zn (17.7 mg kg-1) foram encontrados deficientes. As espécies arbustivas deste estudo podem ser consideradas uma boa fonte de Ca, K, Mg, Fe e Mn, exceto na espécie C. suaveolens. No entanto, P, Cu e Zn devem ser suplementados.
