A 28 day study was conducted to evaluate the effects of feeding on raw and processed Jatropha curcus seeds meal (JSM) on proximate composition of dry matter, crude protein, crude fibre, ash, and ether extracts,weight gain, feed intake, daily protein intake, protein efficiency ratio and feed conversion ratio of Black Nera cockerel chicks. There were forty day-old cockerel chicks in each of thefour treatments comprising of the control, raw, 30 min boiled and 45 min boiled Jatropha curcus seeds meal (JSM) inclusion at 10%, respectively into cockerel diet. A total of 160 birds with an average weight of 28.85 g were completely randomized for the experiment. The results revealed that birds fed on the control diet had higher body weight gain of 299.37 g and feed intake of 498.77 g which were significantly (p<0.05) superior compared with birds on raw (48.49 and 299.91 g), 30 min boiled (68.41 and 393.41 g) and 45 min boiled jatropha seed meals (73.53 and 353.11 g), respectively. Similarly, the feed conversion (FCR) (1.67) and protein efficiency ratios (PER) (2.79) of birds on the control diet were superior (P<0.05) compared with FCR and PER values of 6.18 and 0.70 for raw treatment, 5.79 and 0.79 for 30 min boiled seeds treatment and 1.81 and 0.91 for 45 min boiled dietary treatments. Cockerels fed raw and processed Jatropha curcus seeds meal (JSM) depressedbody weight gain and feed intake. Further research should be embarked upon on other treatment methods or combinations of processing techniques that could detoxify the toxins in Jatropha curcus seeds to improve performance.
