“…In the present study, WBC differentials were significantly affected by breed, CSL, and some interaction. The effects of genotype on these parameters are in agreement with that noted by Tibbo et al [51] and Njidda et al [47]. The finding that diet has no substantial effects on blood platelets concord with Oliveira et al [51] who observed similar result for Santa Inês lambs fed various mixture of physic nut meal with soya bean meal and ground corn.…”

The finding that diet has no substantial effects on blood platelets concord with Oliveira et al [51] who observed similar result for Santa Inês lambs fed various mixture of physic nut meal with soya bean meal and ground corn. Lack of significant difference among genotypes on platelets contradicts with those of Jawasreh et al [54] who obtained significant breed effect for platelets on different genetic lines of Awassi ewes.…”

“…The lack of effect between CSL on PCV in the present study is in line with that reported by Okah et al [50] for west African Dwarf sheep supplemented with different levels of poultry droppings (10%, and 20%). Lack of difference for Hgb concentration between supplement levels is in agreement with other study conducted using Santa Inês lambs fed various mixture of physic nut meal with soybean meal and ground corn [51]. Increased level of Hgb concentration is attributed to ability to tolerate infection and good nutritional status as well as breed of animals [47] [48] [49].…”

An experiment arranged in 2 × 3 (2 concentrate supplement levels (CSL) and 3 breeds) factorial was carried out to evaluate the effect of CSL, breeds, and their interaction on feed intake, digestibility, feed utilization efficiency, and blood profiles of Ethiopian fat-tail hair sheep. The CSL were 1% and 1.75% body weight, designated as L1 and L2, respectively. The breeds used were yearling intact male Blackhead Ogaden (BHO), Horro and Washera. Sixteen sheep from each breed were divided into two based on initial body weight and randomly allocated to two dietary treatments for digestibility and growth trials of 10 and 90 days, respectively. Grass hay as a basal diet was offered ad libitum to each sheep. Feed intake every day and live body weight at interval of ten days were recorded for the duration of the experiment. Blood samples and linear body measurements were taken a week before the end and on the last day of the experiment from all sheep, respectively. Dry matter and nutrient intakes, except concentrate supplement and CP, were influenced by the interaction. The higher (p < 0.0001) DM digestibility was recorded from sheep supplemented with L2 than L1. Consequently, sheep supplemented with L2 had significantly higher (P < 0.05) feed conversion efficiency (FCE), average daily gain (ADG) (57.3 vs 44.2 kg), total gain (TG) (5.3 vs 3.9 kg) and final body weight (FBW) than those supplemented with L1. Among breeds, Horro sheep recorded higher (P < 0.05) DM intake, digestibility, and FCE than the rest of the breeds. Consequently, this breed has significantly (p < 0.05) higher TG, ADG, and FBW. Some of the blood hematology (PCV, MCV, neutrophils, and monocytes) and sera metabolites (total protein, urea, and cholesterol) How to cite this paper: Ayele, S., Urge, M. 150values were influenced by the interaction in favor of L2. Hemoglobin concentration was higher for Washera than the other breeds (p < 0.05) but similar for the two CSL (P > 0.05). In conclusion, the study indicate the presence of variation in nutrient intake and utilization, performance traits, and blood profiles among breeds and between CSL, most of which were in favor of Horro breed and high level of concentrate.

“…The inclusion of the pericarp of J. Curcas in the sheep diet promoted dose-dependent reduction in feed intake and was attributed to the association of several toxic compounds present in the plant (FERREIRA et al, 2012). However, in an experiment where only the most toxic compound (phorbol ester) was absent, these other substances did not affect consumption or performance in sheep (OLIVEIRA et al, 2013). The decrease in food consumption is associated with the presence of toxins and also the decrease of the palatability of the diet plus JC.…”

Jatropha has been highlighted as an oleaginous potential for the production of biofuel. The cake, produced by oil extraction, could be used in animal feed. However, some varieties of jatropha are toxic by limiting their incorporation into animal diets. The objective of this study was to evaluate the hepatotoxicity of diets added with jatropha cake -JC (Jatropha curcas) in rats. Thirty-five (35) male Wistar adults rats (Rattus norvegicus) with initial weight of 352.1 ± 26.8 g were used. The animals were fed for 21 days with the diets: control, 10, 25, 40 and 50% JC. In the feeding with 50% JC the animals presented themselves prostrate and with piloerection. Development and survival decreased, since the inclusion of JC in diets increased. In rats submitted to 10 and 25% JC there was an increase of 17.52% in the hepatosomatic index in relation to the control group. Increase of JC in the rat diet promoted an increase in the activity of ALT and AST enzymes. Anatomic-histopathological evaluation demonstrated that, regardless of the levels tested, JC in rat diet causes hypertrophy of the hepatocytes, with a reduction in energy reserves. This study demonstrated that the use of JC resulted in decreased food intake, associated with weight loss due to the clinical pattern of toxicity, demonstrated by biochemical and histopathological changes in the liver. It was concluded that the inclusion of jatropha cake in rat feeding presents high hepatotoxic potential leading to lesions in the liver parenchyma. Keywords: Toxic. The hepatotoxicity. Animal feed. ResumoO pinhão-manso tem se destacado como oleaginosa potencial para a produção de biocombustível. A torta, coproduto da extração do óleo, poderia ser utilizada na alimentação animal. No entanto, algumas variedades de pinhão-manso são tóxicas, limitando sua incorporação em dietas animais. Objetivou-se neste estudo avaliar a hepatotoxicidade de dietas acrescidas de torta de pinhão-manso (Jatropha curcas) em ratos. Foram utilizados trinta e cinco (35) ratos Wistar (Rattus norvergicus) machos adultos com peso inicial de 352,1 ± 26,8 g. Os animais foram alimentados por 21 dias com as dietas: controle, 10, 25, 40 e 50% TPM. Na alimentação com 50% TPM os animais apresentaram-se prostrados e com piloereção. O desenvolvimento e a sobrevivência apresentaram diminuição conforme o aumento da inclusão de TPM nas dietas. Em ratos submetidos a 10 e 25% TPM houve aumento de 17,52% no índice hepatossomático em relação ao grupo controle. O aumento de TPM na dieta de ratos promoveu aumento da atividade das enzimas ALT e AST. A avaliação anatomo-histopatológica revelou que, independentemente dos níveis testados, a TPM na alimentação de ratos provoca hipertrofia dos hepatócitos, com redução das reservas energéticas. Este estudo demonstrou que a utilização de TPM resultou em diminuição do consumo de alimento associado à perda de peso devido ao quadro clínico de toxicidade demonstrado pelas alterações bioquímica e histopatológica no fígado. Conclui-se que a inclusão de torta de pinhão-manso ...

“…J. curcas seed cake (JSC) has a potential to complement and partially substitute for corn and soybean meal (SBM) as a protein and energy source in ruminant diets. At present, the information regarding to the feeding value of seed cake of non-toxic J. curcas as feedstuff in finishing diets to lambs is scarce (Megumi et al, 2011;Oliveira et al, 2013), and impact of high levels of inclusion of JSC on growth performance and dietary energetics has not been assessed. Therefore, the objective of this experiment was to evaluate the feeding value of a seed cake product obtained from the Mexican nontoxic genotype J. curcas as a partial replacement for corn and soybean meal in a finishing diet fed to lambs.…”
