Abstract
Assessment of physical and grain properties of bagaruwa (Acacia nilotica) tanned
leathers obtained from three Nigerian breeds of goats was done using skins for
seventy two, 2-3 years Red Sokoto, West African Dwarf and Sahelian goats. The
study was laid out in a completely randomized design. The parameters investigated
were thickness, percentage elongation, flexing endurance and grain properties. The
results indicated significant differences (P < 0.05) between the leathers from the
three goats’ breeds in all the physical and grain properties except in the force at
burst. Sahelian (SAH) breed had the highest leather thickness (1.29mm ± 0.09),
which was significantly thicker (P < 0.05) than leathers of both West African
dwarf (WAD) and Sokoto red goat (SRG). Both SAH and SRG had significantly
higher (P < 0.05) percentage elongation (85.38% ± 0.3.90 and 84.13% ± 3.68
respectively) than WAD (65.78% ± 2.19). Flexing endurance (%) was similar for
the three breeds, but SAH leather had significantly higher (P < 0.05) load of crack
and distension at both crack and burst than both WAD and SRG. The present
study suggests that the use of vegetable tanning produced leathers with acceptable
physical and grain properties from the three goat breeds. It further revealed that
WAD and SAH breeds of goat have good leather physical and grain properties and
could equally become valuable like SRG in the leather global market.
