%X The objective of this study was to evaluate the reproductive parameters of &#8220;Lohmann Brown&#8221; strain chickens fed on <i>Cajanus</i> <i>cajan</i> leaves and to assess the viability of the chicks after hatching. 40 hens of the &#8220;Lohmann Brown&#8221; strain fed on <i>Cajanus</i> <i>cajan</i> leaf flour laid 219 eggs divided into four batches depending on the rate of incorporation of <i>Cajanus</i> <i>cajan</i> leaf flour in the rations (0%, 5%, 10% and 15%) were trained and introduced into the incubator. Results: the incubator indicates a hatching temperature of 38&#730;C to 37.2&#730;C and relative humidity of 60% to 70%. Hatching performance shows that: The 15% batch recorded the highest fertility rate 86.95% compared to 26.88% of the control batch. The CC 15% batch recorded the highest hatching rate 36.87. The lowest rate (17.18%) was recorded in the control batch (CC 0%). The highest embryonic mortality rate was recorded in the CC 15% batch. The lowest rate in the CC 10% batch. Concerning unfertilized eggs, the highest rate is 72.20% (CC 0%), and the lowest are (12.03%; 57.42% and 66.66%) recorded in CC batches. 15%, CC 5% and CC 10% respectively. For the shell mortality rate, the highest is 18.58% recorded in the CC 15% batch. The lowest shell mortality rate is 2.07%, obtained in the control batch (CC 0%); the dust mortality rate was 0% for all chicks. The study seems to indicate that the incorporation of <i>Cajanus</i> <i>cajan</i> leaf meal up to 15% into the reproduction type ration in hens does not cause any harmful effects on the reproduction performance of laying hens.
