Three experiments were conducted to evaluate the nutritional and feeding value of local vegetable protein ingredients; red pepper seed oil meal (RPSOM), sesame oil meal (SOM) and perilla oil meal (POM) for poultry feeding. In the first experiment, nutritional values of RPSOM were evaluated by analyzing chemical compositions and determining true metabolizable energy (TME), nitrogen corrected TME (TMEn) and true available amino acid (TAAA) contents. According to the chemical analysis, RPSOM contained 22.50% of crude protein, 4.75% of ether extract, 27.70% of crude fiber, 0.34 mg/g of capsaicin and 49.97 ppm of xanthophylls. The values of TME and TMEn determined by force-feeding 16 roosters (ISA-Brown) were 2.96 kcal/g and 2.55 kcal/g on dry matter basis, respectively. The average TAAA value of 16 amino acids measured by the force-feeding technique was 81.70%. These values were used for formulating experimental diets containing various levels of RPSOM for broiler chicks and laying hens. Two feeding trials were made to investigate the effects of dietary incorporation of RPSOM into chicken feed on performances of broiler chicks and laying hens. In the broiler feeding, a total of two hundred twenty-five, 4 wk old male broiler chicks (Ross) were randomly divided into 9 groups of 25 birds each and assigned to three experimental diets containing 0, 5 and 10% RPSOM. The birds were fed ad libitum the diets for 3 wk and feed intake, weight gain and feed conversion rate were determined. At the end of the feeding, the blood levels of glutamate oxaloacetate transaminase (GOT), gamma glutamyl transpeptidase (GGT), blood urea nitrogen (BUN) and cholesterol, and the body and fatty acid compositions of leg muscle were measured. No significant differences were observed in weight gain, feed intake, feed conversion rate, body composition, serum levels of GOT, GGT and BUN among the treatments. However, blood cholesterol level was lower (P<0.05) in 10% RPSOM diet group than those in the others. The dietary RPSOM at 5 and 10% levels increased the content of linoleic acid (P<0.05) in leg muscle compared to that of control group. The results indicate that RPSOM can be used for broiler feed up to 10% without any significant negative effects on broiler performance. In the layer feeding, the effects of dietary RPSOM on the performances of laying hen were investigated by feeding ninety 45 wk old laying hens (ISA-Brown) with experimental diets containing 0, 5 and 10% RPSOM for 4 wk (30 birds per treatment). Measurements were made on egg production rate, egg weight, feed intake, Haugh unit, egg shell strength, egg shell thickness, total lipid and cholesterol contents and fatty acid profile in egg yolk. The dietary incorporation of RPSOM did not affect all the parameters except egg shell strength which was higher (P<0.05) in layers fed 10% RPSOM diet compared to those fed 0 and 5% RPSOM diets. Thus, it can be concluded that RPSOM can be included into laying hen feed up to 10% without any harmful effects. The second experiment was to examine the effects of dietary SOM on the performances, quality and fatty acid profile of egg, and blood parameters of GOT, GGT and cholesterol in laying hens fed three different diets containing 0, 5 and 10% SOM for 4 wk. The inclusion of SOM into laying hen diets at 5 and 10% level did not affect egg production rate, egg weight, daily egg mass, feed intake, Haugh unit, yolk color, egg shell strength and thickness, total lipid and fatty acid profile of yolk. None of the blood parameters examined were affected by the SOM inclusion indicating that SOM can be included into laying hen feed up to 10% without any adverse effects, if its nutritional values are well evaluated. The third experiment was carried out to assess the effects of POM inclusion into laying hen diet on laying performances, egg quality and blood parameters of GOT, GGT and cholesterol. A total of ninety 54 wk laying hens were divided randomly into 3 groups and assigned to three experimental diets containing 0, 5 and 10% POM. Measurements on performance, egg quality and blood parameters were made by the same manner in the second experiment. All the average values measured during the experimental period were not significantly different among the treatments except egg weight, in which the bird fed 10% POM diet produced significantly smaller eggs (P<0.05) than the other birds. The results suggest that POM can be included into laying hen feed up to 5% without any adverse effects, if its nutritional values are well evaluated.
