... Besides, Lihua et al. (2004) showed that the leaf extract of J. curcas plant possesses an in vitro antibiotic effect on chicken pathogens, such as Escherichia coli and Staphlococcus aureus. Moreover, a recent study has shown the anti-tick activity of Jatropha meal in rabbits (Abdel-Shafy et al., 2010;Nasr et al., 2011). ...
... Earlier study shows that jatropha seed meal treated using physical and biochemical method to investigate the nutritional value and effect on cockerel diet indicated that there was no significant difference in feed intake and body weight gain compared to the control group [2]. Nasr et al. [31] reported that administering Jatropha seed meal (JSM) at 2.5% normal diet was not toxic in rabbits, while 5 or 7.5% JSM exhibited slight adverse sero-biochemical and histopathological alterations, although 10% JSM exhibited some sero-biochemical and histopathological alteration in liver and kidney functions. ...
A study was carried out for ten weeks to evaluate effect of including treated and untreated jatropha seed meal (JSM) in the ration on feed intake, body weight gain, mortality, and carcass and meat quality traits of Koekoek chicks. Chicks were allotted in five treatment diets with replications and 20 chicks per replication in a completely randomized design. Treatment diets were: T1 = control, T2 = (T1 + untreated), T3 = (T1 + heat treated), T4 = (T1 + NaOH treated) and T5 = (T1 + yeast treated JSM) in which 5% of soybean in T1 was replaced by the respective JSM in T2–T5. The daily body weight gain (DBWG)) was higher (p < 0.05) for chicks fed on T1 and T4 than chicks on T2, T3 and T5. Chicks fed on T1 and T4 diets had higher feed intake than those kept on T2, T3 and T5 diets at (p < 0.05). Chicks receiving the T2 diets had highest FCR followed by T5, T3, T4 and T1, respectively. However there were no significant variations among all the treatment groups. Chicks fed T2 had higher (p < 0.05) mortality rate than chicks in T1, T3 and T4 diets. Slaughter and dressed carcass weight of chicken fed the control diet were significantly the highest (p < 0.05) and T2 was lowest of all other chicken fed treated experimental diets. Thus, it can be concluded that chicks under T1 and T4 had better DBWG, FCR, final body weight and better survivability and carcass characteristics than chicks receiving diets with T2 followed by T3 and T5. Therefore, inclusion of NaOH treated JSM could be used to substitute soybean seed in the diets of growing chicks.

Jatropha curcas L. has gained importance as a source of seed oil for biodiesel production. The meal contained about 60% protein with a good balance of essential amino acids, containing various bioactive compounds, including saponins, phytic acids, trypsin inhibitors, lectins, phenol-ics, and flavonoids, which render it as a potential biofeed for animal production. The Jatropha meal demonstrated various biological activities, including antioxidant, antibacterial, and anti-inflamma-tory effects which enhance its property as a bio-feed. The levels of these bioactive compounds in the seeds are dependent on the genotypes. The J. curcas possessed different varieties which are either toxic or non-toxic according to the presence of phorbol esters. The presence of phorbol esters in the meal confirmed the toxic variety of Jatropha resulting in the limited application of meal as a biofeed. The Jatropha meal devoid of phorbol esters could be applied as a biofeed in the animal production industry, and for the toxic varieties, various techniques such as physicochemical and biological treatments have been introduced to the industry to remove the phorbol esters from Jatropha meal. Several studies employing various cells and animals confirmed the toxicity of the phorbol esters. The molecular mechanism of action of phorbol esters is through up-regulation of PKC-β II gene, overexpression of downstream proto-oncogenes resulted in inflammation and oxidative stress ending by apoptotic cell death. Despite the presence of valuable bioactive compounds in the Jatropha meal, its nutritional application is not recommended unless the phorbol esters are completely removed .
... Through laboratory analysis, J. curcas seed meal free of shells has been found to have high nutritive value comparable to that of soybean meal because it is rich in protein (27 to 33%) (Makkar et al., 1998;Abou-Arab and Abu-Salem, 2010;Abdel-Shafy et al., 2011). Nasr et al. (2011) indicated that the administering of Jatropha seed meal (JSM) at 2.5% normal diet was not toxic in rabbits, while 5 or 7.5% JSM exhibited slight adverse sero-biochemical and histopathological alteration; although 10% JSM exhibited some sero-biochemical and histopathological alteration in liver and kidney functions. The plant is adaptable to extreme growing conditions, tolerates high temperature and is resistant to drought. ...
This study was carried out to evaluate the effect of incorporating the Jatropha curcas meal in place of black cumin seed meal (Nigella sativa) as a new source of protein on nutrients digestibility, feeding value, growth performance and economic efficiency of growing Demeshgi goats rations. Feeding trial which lasted for 90 days was conducted using 12 growing Demeshgi goats (average 23.26 kg live body weight and 6 to 8 months old). The animals were randomly divided into four groups and fed at 3% of live body weight on four experimental rations. The first group received control ration consisting of feed mixture (40% yellow corn grains; 20% cumin seed meal; 17% wheat bran; 20% bean straw, 2.0% lime stone and 1.0% salt). In the second, third and fourth rations, cumin seed meal (CSM) was replaced with 10.0, 20.0 and 30.0% Jatropha seed meal (JSM), respectively. The chemical composition, digestibility coefficients, nutritive values, daily gain, feed conversion and economical efficiency were determined. The results indicated that digestion coefficients of all nutrients and nutritive value were not significant in four tested rations. The highest value of average daily gain (p < 0.05) was recorded for goats fed on R1 and R2 compared with those fed R3 and R4. Feed conversion as a kg DMI/kg gain was significantly (p < 0.05) better for G1 and G2 (7.10 and 7.04) than 7.35 for G3 and 8.05 for G4. Total feed cost was decreased for R4 and R3 (577.73 and 580.66 L.E./h) compared with 593.16 and 592.01 L.E./h for R1 and R2, respectively. On the other hand, the economic efficiency of animals fed rations containing 10 and 20% JSM was higher (16.04 and 15.66%) than those fed 0 and 30% JSM (14.47 and 14.0%), respectively. Similar trend was noticed for relative economic efficiency value (110.85 and 108.22%) recorded for R2 and R3 compared with 100 and 96.75% for R1 and R4, respectively. This study therefore recommend that further researches may be required to study the effect of increasing the level of JSM used in goat rations than 30%, which did not cause any adverse effect on the animals.
