Selenium is a micromineral
essential for fish growth (Hamilton, 2004).

Zinc is an essential micromineral
that has many function and role in the body, thats are: stabilizing cell membranes, helping the body's defense against free radical attacks, play a role in the body's immune system, as well as the process of growth and development.
Effect of dietary organic and inorganic micromineral

Comparative slaughter trials (CST) are commonly used to estimate the protein, energy, macromineral, and micromineral
requirements of animals (Chizzotti et al., 2007; Fernandes et al., 2012; Souza et al., 2013).
Once slaughtered, the rabbit caecum was excised, and total caecal contents (around 300g) were removed and diluted under a C[O.sub.2] stream in 300ml of incubation solution, without resazurin and micromineral
solution, using HCl-cysteine as the reducing agent (MOULD et al., 2005) and filtrated in three gauzes of cheesecloth, after which caecal content (10ml) was taken, supplemented with 90ml of buffer solution and inoculated into triplicate bottles (100ml total volume) with 0.8g of forage silage as substrate, according to the method proposed by THEODOROU et al.
Esse esta ligado aos mecanismos fisiologicos envolvido com o desempenho e resistencia fisica, sendo assim a deficiencia para este micromineral
, pode acarretar anemia, o que podera comprometendo o desempenho atletico (Mielgo-Ayuso e colaboradores, 2015).
Rumen fluid mixture was freshly prepared as described by Menke and Steingass (1988), mixing 400 mL rumen fluid, 400 mL distilled water, 200 mL ammonium carbonate buffer pH 8.0, 200 mL macromineral, 1 mL 0.1% (w/v) resazurine, 0.1 mL micromineral
and 40 mL reduction solution.
