The experimental rations consisted of replacing soybean meal by palm kernel meal at the rates of 50, 75 and 100 percent supplemented with lysine-methionine and spirulina and a control ration without palm kernel meal. The main results revealed that, all the growth parameters decreased with increasing rate of substitution of soybean meal with palm kernel meal. Compared to the control ration containing soybean meal as main protein source, feed conversion ratio increased by 25.97; 39.39 and 71.43 % with lysine-methionine mixture and by 40.34; 53.22 and 62.66% with spirulina in rations containing 50, 75 and 100 % palm kernel meal respectively. Carcass yield globally decreased, with the exception of carcass yields with 75% palm kernel meal supplemented with lysine-methionine that increased by 3.48 % compared to the control ration. The relative weight of the legs, head and digestive organs increased with increasing rate of palm kernel meal in feed regardless of the supplement. The lowest cost of production was recorded with spirulina compared to lysine-methionine regardless of the level of incorporation of palm kernel meal in feed. In conclusion, using large quantities of palm kernel meal even enriched with amino acids or proteins rich resources is not profitable to broiler chickens.

A total of 65 frogs (22 males, 22 females and 21 unspecified frogs) were obtained from hunters in 3 localities namely: Loum, Penja, and Nlonako in the Moungo division, littoral region of Cameroon. The methods of dissection, measurement, and stomach content analysis were used. The results revealed a large diversity of preys in the stomach namely: myriapods (25%), plants leaves and steems (21.19%), insects (19.56%), indigestible matters (19.56%), arachnids (4.89%), crustaceans (4.34%), mollusks (3.26%), amphibians (0.54%), annelids (0.54%) and reptiles (0.54%). The numerical percentage and the frequency of myriapods occurrence were significantly (P < 0.05) higher in males captured in the locality of Loum (100% and 35.55%) compared to the females (28.57% and 18.18%). Comparing the state of maturity, the numerical percentage and the frequency of occurrence of insects (100...

TS (Imported Skreting feed), T0 (feed without supplement), T(0.1%F) (feed containing 0.1% A. lepidophyllus fruit bean powder), T(0.2%F) (food containing 0.2% fruit bean powder of A. lepidophyllus). These feeds were distributed 4 times a day to the fry at a regular time interval of 3 hours including 7 a.m., 10 a.m., 1 p.m. and 4 p.m. the fry were fed at 11% of their biomass for one month and then at 10% for six weeks. The analysis of variance showed no significant difference (p > 0.05) in the survival rates (97.66 ± 1.02%-98.66 ± 0.90%) but a trend on the rise in favor of feeds supplemente...
