==EQ of livestock animals==
The EQ of livestock farm animals such as the [[domestic pig]] may be significantly lower than would suggest for their apparent intelligence. According to Minervini et al (2016) the brain of the domestic pig is a rather small size compared to the mass of the animal.<ref name="Minervini_2016">{{cite journal |last1=Minervini |first1=Serena |last2=Accogli |first2=Gianluca |last3=Pirone |first3=Andrea |last4=Graïc |first4=Jean-Marie |last5=Cozzi |first5=Bruno |last6=Desantis |first6=Salvatore |title=Brain Mass and Encephalization Quotients in the Domestic Industrial Pig (Sus scrofa) |journal=PLOS ONE |date=28 June 2016 |volume=11 |issue=6 |pages=e0157378 |doi=10.1371/journal.pone.0157378 |pmid=27351807 |pmc=4924858 |bibcode=2016PLoSO..1157378M |doi-access=free }}</ref> The tremendous increase in body weight imposed by industrial farming significantly influences brain-to-body weight measures, including the EQ.<ref name="Minervini_2016" /> The EQ of the domestic adult pig is just 0.38, yet pigs can use visual information seen in a mirror to find food, show evidence of self-recognition when presented with their reflections<ref>{{Cite journal|last1=Broom|first1=D.
