A 90-day feeding trial, followed by a 15-day digestibility trial was conducted using 2 groups of sheep and 2 groups of goats (6 animals per each group) to evaluate the feeding value and utilisation of two kinds of pelleted feed supplements: a commercial concentrate feed mixture (CFM) and an organic waste feed mixture (OWFM), as a non-conventional feed, in addition to barley straw. During the feeding trial, constant voluntary DM intakes of CFM and OWFM were achieved at the same time after the first 3 weeks of feeding for both sheep and goats. All feed ingredients and rations were free of aflatoxins and bacterial toxins. No digestive disorders occurred during the study. Goats consumed OWFM more than CFM whereas sheep consumed comparable amounts of both diets. Animals fed the OWFM diet (S2 and G2) utilised and digested the nutrients more efficiently and retained more N (379 and 317 mg per kg W0.75, respectively) than those fed the CFM diet (S1 and G1). The nutritive values of the OWFM diet were much better in terms of TDN and DCP. Values of GPT, GOT and GGT enzymes were in normal ranges. Such results recommend that the non-conventional feed supplements (OWFM) could be efficiently used as nutritious, palatable and low-cost feed resources for small ruminants in Egypt.
