| The present study was carried out with the objective of evaluating the effects of feeding dairy cows with organic or inorganic sources of zinc (Zn), copper (Cu) and selenium (Se) on blood concentrations of these minerals, blood metabolic profiles, nutrient intake and milk yield and composition. Nineteen Holstein cows were selected and randomly assigned to two groups for receiving organic (n = 9) or inorganic (n = 10) sources of Zn, Cu and Se from 60 days before the expected date of calving to 80 days of lactation. Samples of feed, orts and milk were collected for analysis. Body condition score (BCS) was determined and blood samples were collected for analysis of Zn, Cu and Se concentrations, as well as for metabolic profile. Supplying organic or inorganic... |

| ABSTRACT Among the nutrients involved in the chicken diet, the microminerals deserve attention as they exert essential functions in the organism. These compounds can be provided in inorganic (traditional) and organic (chelate) forms. In organic form, the micromimerals can attend a new concept related to a better bio-availability. In this sense, the objective of this work was to evaluate the effect of the partial and total substitution of inorganic by organic sources of microminerals on the animal diet, assessing its concentration in the blood and liver after 21 and 40 days and also in the bones after 40 days. Moreover, the effect on the physical-chemical and sensory characteristics of the muscle after 15 days of storage at 4°C was also evaluated. The... |
