  The energy and momentum of the Bianchi type $III$ universes are obtained
using different prescriptions for the energy-momentum complexes in the
framework of General Relativity. The energy and momentum of the Bianchi $III$
universe is found to be zero for the M\o{}ller prescription. For all other
prescriptions the energy and momentum vanish when the metric parameter $h$
vanishes. In an earlier work, Tripathy et al. \cite{SKT15} have obtained the
energy and momentum of Bianchi $VI_h$ metric and found that the energy of the
Universe vanish only for $h=-1$. This result raised a question: why this
specific choice?. We explored the Tryon's conjecture that 'the Universe must
have a zero net value for all conserved quantities' to get some ideas on the
specific values of this parameter for Bianchi type Universes.
