Three hundred 8-week-old black Harco pullets were used to establish the optimum level of bovine blood-rumen content meal (BBRCM) that grower birds can tolerate, and its effects on the subsequent laying performance of test birds. At the growing phase, the experimental diets contained 0, 5, 10, 15, and 20 per cent BBRCM, while at the laying phase treatment birds were fed a common layer mash devoid of BBRCM. The performance of pullets at the growing phase was not influenced (P0.05) by the inclusion of BBRCM. The rate of lay tended to increase with the increasing level of BBRCM in diets. The mean egg weights were comparable for birds on all treatments, except for the smaller eggs laid by the hens on the 20 per cent BBRCM diet (P0.05).
