If an aggressive bull is allowed to graze outside, additional precautions may be needed to help avoid him harming people. To assist in their search, the olfactory and gustatory receptors able to detect minute amounts of sodium salts increase their sensitivity as biochemical disruption develops with sodium salt depletion.[80][81]. 2011. [178] Since that time, the EPA has established CAFOs as an enforcement priority. Their fertility is closely related to the size of their testicles, and one simple test of fertility is to measure the circumference of the scrotum; a young bull is likely to be fertile once this reaches 28 centimetres (11 in); that of a fully adult bull may be over 40 centimetres (16 in).
