- Abstract
Jatropha curcas is a tropical plant belonging to the Euphorbiaceae family whose cultivation has been largely promoted in recent years for the production of biofuels. 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 deoiling 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 used in two experiments. In experiment 1, jatropha kernel was de-oiled and incorporated into a control fattening (OJKMJ feed at 40 and 80 g/kg (diets 4JKM1 and 8JKMJ. In experiment 2, jatropha kernel meal obtained in experiment 1 was heat treated and incorporated into a growing diet at 80 g/kg (diet 8JKMJ. 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 (ADFIJ of 139.2, 55.2 and 23.4 g/day/animal and also average daily weight gain (ADWGJ of 61.9, 18.5 and -7.7 g/animal were obtained respectively for the groups fed with diets 0JKMp 4JKM1 and 8JKMr In experiment 2, Average Daily Feed Intake (ADFIJ of 18.7 and 3.1 g/day/animal and also Average Daily Weight Gain (ADWGJ of 7.1 and 1.9 g/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.
