Macro Mineral in Nelore Cows of Different Ages from the Bolivian Tropics
Author(s): Atsuko Ikeda, Pablo Roberto Marini
The objective of the work was to evaluate if the multiparous adult cows presented any difference in the values of macro minerals compared to
young primiparous Nelore cows from the Bolivian tropics. During the month of February 2021, a study was carried out with 14 multiparous
adult cows and 13 young primiparous cows, belonging to the Technology Center on Agriculture and Livestock in Bolivia (FUNDACION
CETABOL) Santa Cruz, Bolivia. The following variables were analyzed: Calcium, Phosphorus, Sodium, Potassium, Chlorine, and Magnesium.
The cows used were: Adult cows of 4561 ± 95 days and Young cows of 1535 ± 99 days (p≤0.001). The values of the macro minerals analyzed
and all of them have the values between the normal ranges and without showing significant differences between both groups.
Although the Phosphorus beyond having normal values, there are significant differences (p≤0.05) with the highest values in young cows. It
is concluded that the multiparous adult cows did not present any difference in the values of macro minerals compared to young primiparous
Nelore cows from the Bolivian tropics.
