Abstract
The influence of breed, sex and slaughter age was examined on the physical properties of leathers of red
Sokoto (RS) and Sahel (SH) goats using a total of forty-eight skins. The skins used for the research were
obtained in equal age and sex ratios for the two breeds and the experiment was laid out in a completely
randomized factorial design. The skins were tanned using vegetable method. The leather properties
examined are percentage elongation (PE), force at crack (FC), distension at crack (DC), force at tear (FT)
and distension at tear (DT). The result revealed that PE and FT of the leather samples were not influenced
(p>0.05) by breed. Similarly, age and sex has no effect (p>0.05) on the DT of the leathers while age had
effect (p<0.05) on PE. The higher the age the higher the PE across the two breeds. Male goats had better
leathers than female with respect to PE and DC while female goats’ leather were better in FC and FT.
Leathers from goats of 3 years age group had higher (p<0.05) values for PE = 34.75%; FC = 21.56kg; DC
= 4.39mm than that of lower age groups in all the parameters except FT of age 1 class (25.84kg). It is
concluded that the RS and SH goats of different sex and ages produce leathers of different physical
properties. It is therefore recommended that the required properties of leather should determines the
choice of age, breed or sex of goats from which skins are collected.
