In this study, molasses/mineral feed blocks and medicated blocks were studied to identify the best way to control gastro-intestinal nematode infection and also improve growth performance of Boer goats in Malaysia. Molasses, urea and other components are used for producing molasses/urea feeds, and provide a suitable way of supplying degradable protein and fermentable energy to ruminant animals. Medicated feed-supplement blocks have been used in an effort to deliver anthelmintic medication. Results shows that molasses/mineral feed blocks and medicated blocks have significant effects (P < 0.05) on final weight, avarage daily gain, carcass length, hot carcass weight, weight of 9th, 10th and 11th rib area, backfat thickness, body wall thickness, ribeye area- REA, eye muscle width, eye muscle depth, lungs, liver, spleen, kidney, heart, empty stomach, empty large intestine, kidney fat, pelvic fat, heart fat, internal fat, leg, hind, shank, chump, rack, ribs, square shoulder, fore shank and neck. According to the results, it can be concluded that a combination of molasses/mineral feed blocks and medicated blocks provided the best growth performance and carcass traits. Thus, the use of urea molasses mineral blocks and medicated urea molasses mineral blocks is recommended
