In order to evaluate the effect of diet supplementation with Moringa oleifera leaf meal (MOLM) on growth and laying performances of quail in soudano-guinean zone of Cameroon, a study has been conducted in Ngaoundéré from May to September 2018. For this purpose, a total of 168 seven weeks old quails were divided into 12 comparable batches of 10 females and 4 males. Each of the four experimental diets (T0, T1, T2 and T3), formulated on the basis of the level (0, 1, 2, and 3% respectively) of diet supplementation with MOLM was randomly assigned to 03 batches in a completely randomized. Data were collected during the 16 weeks of the study on feed intake (FI), body weight (BW), body weight gain and feed conversion ratio. Weekly, after total laid eggs evaluation, 40 eggs per treatment was randomly chosen, weighed and measured. Main findings revealed that FI was not significantly affected by the diet supplementation with MOLM. Significantly higher BW and BW gain was recorded in T1 treatment compared to others treatments while they remains similar between them. The relatively heavier eggs were noted in T2 treatment while the highest (88.57 ± 2.85%) weekly laying rate was recorded with 1% supplementation. It has then been concluded that MOLM could be used as diet supplement during laying phase up to 3% for egg production and 1% of substitution seem to be the most appropriate to increase eggs laying rate while 2% is suitable to obtain heavy eggs in the soudano-guinean agro ecological zone of Cameroon.
