The basic raw materials for a bate have ranged from dog dung and pigeon faeces to synthetic enzymes. The application of the formerly used natural materials was difficult and the quality of the leather produced was not reproducible and was inconsistent. The skins might be over -bated or under -bated depending on the activity of the bate and the enzyme content of the material used. The current material used for the preparation of a bate is cow pancreas, blended with a carrier substance at a suitable concentration giving an activity of about 1300 units. The leather produced using such materials is compared with that produced using a widely applied commercial bating material (Oropon, Rohm and Haas) with regard to quality, strength and softness. Various compositions were used starting from 0.5% at increments of 0.25% to 1.5% based on limed weight. These trials were compared with a controlled experiment using 0.5% of the commercial bating material which has a strength of 1500 units as checked by the method of analysis adopted in this work (Appendix A). 72 wet-salted sheep and goat skins were divided equally into two groups, each group contained 6 skins of either type. The skins of the two groups were processed through soaking, unhairing, liming deliming, bating, pickling, chrome tannage, retannage, drying, and finishing. The leather produced is of good quality and it does not differ from the leather produced using imported bating materials.
