“…With the exception of Fe, minerals introduced into the tureen as a component of soil appeared to be relatively insoluble at the pH found there. As chyme moves from the abomasum to anus, concentrations of the elements (on a DM basis) increase, whereas the soluble fraction available for absorption decreases, as a function of pH (Annenkov, 1979).…”

Two experiments were conducted with lambs fed concentrate-based diets to study the effects of dietary P and soil ingestion on performance, P utilization and mineral composition of serum and alimentary tract contents. In Exp. 1, 20 wether lambs were fed diets for 21 d in a 2 X 2 factorial arrangement of treatments with .2 or .3% total dietary P and O or 9% added Florida Ultisol (highly weathered soil with high P-fixation capacity) containing 4,600 and 6,400 mg/kg total Al and Fe, respectively. True P absorption increased (P less than .05) from 30 to 42% and from 37 to 54% when soil was added to the basal and high P diets, respectively. In Exp. 2, 24 wether lambs were assigned randomly to a 2 X 2 X 2 factorial arrangement of treatments. Lambs were fed during a 70-d period using diets described previously on either a restricted or an ad libitum basis. Soil increased Fe concentration in ruminal fluid (P less than .05) and ash percentage (P less than .001) in ruminal solids and feces. Aluminum concentration in ruminal solids and feces and Fe in ruminal solids were increased (P less than .001) by soil addition, whereas concentrations of Ca, Mg, P, Zn, Cu and Mn in ruminal solids and feces were decreased (P less than .01) by soil addition. There were time X P interactions on serum inorganic P (P less than .01) and Mg (P less than .05) concentrations. Although high in P-fixing capacity, soil fed to lambs in these experiments improved P utilization. Lambs appeared to be able to adapt to changes in intake of dietary minerals in soil, possibly through adaptation of ruminal microflora or a redistribution of body mineral pools.

“…The stocking rate influences the predominance of certain plant species and changes the leaf/stem ratio, which is why it has a direct relationship with the mineral content of the pasture because the leaves are richer in minerals than the stems, the mineral content is Importance of Minerals in the Diet of Cattle in the Tropical Climate of Mexico DOI: http://dx.doi.org/10.5772/intechopen.110491 removed in the plants the more there is a greater grazing and increase in the production of dry matter [20][21][22][23], reported that continuous grazing produced significantly lower levels of Ca, Mg and Cu compared to rotational grazing, there being no differences in their P content in both systems. The minerals are also beneficial for rumen microorganisms [24], the Co serves as food for bacteria that produce vitamin B12, the inorganic S is only used to stimulate the digestion of cellulose within the minerals involved in the digestion of cellulose are Ca, P, K, Mg, S, Mn, Fe, Cu, Co, Zn, Se and I [13].…”

The chapter addresses the importance of minerals in the diet of cattle in a tropical climate to maintain their body condition in relation to productive activity and especially reproductive activity, this importance falls on the physiological processes within the animal organism considering that fantastic world that explain the phenomena that occur within the organism that are important processes since they maintain cellular homeostasis, this allows the generation of cells of the body structure as well as male and female gametes that influence the conservation and maintenance of biochemical phenomena with the emphasis on conserving the organic status that, when unbalanced, generates fertility problems, affecting above all milk and meat productivity, generating economic losses in cattle ranches in southern Mexico. It is convenient to indicate that Mexican soils in a great proportion present deficiencies of minerals such as zinc, selenium, boron, chromium, a few to comment that along with forage production, this is accompanied to produce infertility phenomena in cattle. in grazing that influence the presentation of heats, corresponding to artificial insemination as well as problems in ovarian pathologies that inhibit ovarian cycling and become unprofitable, for this reason this the minerals in the diet is important so that the profitability of milk and meat benefits the producers of the countryside in southern Mexico
