The present study resulting in some data revealed that the application of contraceptive pills in chicks diet is negatively affecting the chick performance as shown from the insignificant (P greater than or equal to 0.05) decrease of body gain, feed conversion efficiency, deposit fat percent, liver weight percent and blood glucose content. Dressing percentage and total edible parts percentages, did not differ significantly (P greater than 0.05). Biochemical parameters in blood were measured and the results are discussed.
