Abstract :
[en] Jatropha curcas is a tropical drought-resistant plant belonging to the Euphorbiaceae family that has gained importance for the production of biodiesel. The kernel of the seed contains approximately 55% lipid in dry matter and the meal obtained could be an exceptional source of protein for family poultry farming, after treatments to remove toxic and anti-nutritional compounds. The ingestion and the growth performance of J. curcas kernel meal (JKM), obtained after partial physico chemical de-oiling combined or not with heating was evaluated in broiler chickens and chicks. Sixty unsexed broiler chickens, 30 day-old, divided into three groups as well as twenty broiler chicks, 1 day-old, divided into two groups were obtained for two experiments. In experiment 1, jatropha kernel was de-oiled and incorporated into a control fattening feed at 40 and 80g/kg (diets 4JKM1 and 8JM1). In experiment 2, jatropha kernel meal obtained in experiment 1 was heat treated and incorporated into a growing diet at 80g/kg (diet 8JKM2). Daily dietary intakes as well as weight gain of the animals were affected by the incorporation of jatropha kernel meal in the ration. In experiment 1, average daily feed intake (ADFI1) of 139.2, 55.2 and 23.4g/day/animal and also average daily weight gain (ADWG1) of 61.9, 18.5 and -7.7g/animal were obtained respectively for the groups fed with diets 0JKM1, 4JKM1 and 8JKM1. In experiment 2, Average daily feed intake (ADFI2) of 18.7 and 3.1g/day/animal and also average daily weight gain (ADWG2) of 7.1 and 1.9g/animal were obtained respectively for the groups fed with diets 0JKM2 and 8JKM2. In both experiment, feed conversion ratio (FCR) was also affected by the dietary treatments and the overall mortality rate showed an increase according to levels of jatropha kernel meal in diet.
