The red cell X-protein, NADH-diaphorase 1, malic enzyme and serum arylesterase phenotypes of 50 Thai Longtail and 53 Cameroon X Thai Longtail(F1) crossbred sheep were determined by horizontal starch gel electrophoresis. None of the economic traits was influenced by DIAI, ME and EsA phenotypes. However, CP phenotypes showed a highly significant association with body weight, body height, heart girth and back girth, with mean values of XP+ve phenotype greater than XP-ve. The XP+ allele was associated with greater body weight, body height, heart girth and back girth.
