| description | The phenotype, growth performance and the reproductive
status of 60 heads of male and female gaur x cattle hybrids
were recorded and compared with Sahiwal-Friesian crossbred
cattle.
The main objectives of this experiment were to evaluate
the phenotype of the hybrids, the growth potential for beef
production and to assess the reproductive capabilities of these
hybrids for future propagation. The present result shoved that the phenotypic features
could be utilised to identify this gaur x cattle hybrils . They
showed similar growth pattern as the Sahiwal-friesian crossbred
cattle indicating a faster growth rate at any phases of the
growth curve. The fast growth rate and high carcass value of
the gaur x cattle hybrids indicate that these animals have the
potential for beef production.
The gaur x cattle hybrids were not sterile as speculated.
The male hybrids showed normal libido and mating behaviour
but rated as questionable potential breeders due to the small
scrotal circumference, high incidence of sperm abnormalities
and poor sperm quality. Natural mating
hybrids were related to low pregnancy
involving the male
rate with a high
incidence of pregnancy wastage, therefore not suitable for use
as breeding bulls . However the female hybrids can maintain
normal pregnancy, produce high calf crop and normal calf which
indicate that they were not affected by the interspecific
hybridization and may be used for the propagation of these
animals. |
