The objective of this study was to investigate the effects of sumac and turmeric on performance, egg quality traits, and blood parameters of laying hens. Forty Lohman Brown hens at 30 weeks of age were distributed into four groups, consisting of five replicates with two hens in each. The experiment lasted for 42 days. Laying hens were fed different basal diets in treatment groups and control groups. The groups consisted of hens fed a basal diet with 0.5% sumac, a basal diet with 0.5% turmeric, and a basal diet with 0.25% sumac + 0.25% turmeric. Hens were given ad libitum access to feed and water during the experiment. The results revealed that there were no statistically significant differences in terms of final body weight, egg production, egg weight, and feed intake after the groups were fed according to the diets as 0.5% sumac, 0.5% turmeric, and 0.25% sumac + 0.25% turmeric. Addition of turmeric increased egg production and egg weight, but reduced the feed conversion ratio compared with the control group. On the other hand, dietary supplementation with sumac decreased egg weight. Shape index, yolk index, albumen index, Haugh unit, and yolk color parameters were also not affected by dietary supplementation of turmeric and sumac. When layers were fed the 0.25% sumac + 0.25% turmeric-supplemented diet, yolk index was higher in number, but Haugh unit and albumen index were lower. Dietary addition of sumac and turmeric does not have any negative influence on performance and egg quality traits of laying hens. Dietary treatments do not significantly affect blood serum cholesterol, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels. With the supplementation of turmeric, AST and ALT levels are higher in number among all the groups. Dietary sumac and turmeric can be added at 0.5% level to laying hen rations without changing animal performance.
The aim of this study was to evaluate the incidence of total aflatoxin (AF), ochratoxin A, T-2 toxin, deoxynivalenol (DON), zearalenone (ZEA), and fumonisin (FB) in dairy cattle, beef cattle, and lamb-calf feeds. A total of 180 dairy cattle, beef cattle, and lamb-calf feeds (60 samples each) were randomly collected from farms, feed mills, and villages in Burdur province, between September 2006 and August 2007. All samples were analyzed by the competitive Enzyme Linked Immuno Sorbent Assay (ELISA). The most frequent mycotoxin detected was total AF, which was found in 108 samples (60 %) in concentrations ranging from 3.82 to 116.83 μg kg(-1), followed by DON that was detected in 87 samples (48.3 %), in concentrations ranging from 18.50 to 500 μg kg(-1). Ochratoxin A (OTA), T-2 toxin, ZEA, and FB were found in 84 (46.7 %), 85 (47.2 %), 57 (31.7 %), and 19 (10.6 %) samples, respectively, in concentrations of 1.01 to 15.85 μg kg(-1) for OTA, 3.85 to 52.36 μg kg(-1) for T-2 toxin, 2.10 to 29.30 μg kg(-1) for ZEA, and 2.69 to 4.96 mg kg(-1) for FB. It was concluded that feed samples in Burdur province were contaminated by mycotoxins, and the levels of total aflatoxin in the samples were considered a risk to animal health.
The objective of this research was to evaluate the effects of fennel seed (Foeniculum vulgare Mill.) supplementation of ration on performance, egg quality, and serum cholesterol of laying quails during an eight-week period. For this purpose, 96 quail (Coturnix coturnix japonica) of 16 weeks of age were evenly separated into one control group and three treatment groups. Each group was divided into four replicates, each containing six quail. The fennel seeds (Foeniculum vulgare) were added to the diets of the first, second, and third treatment groups at levels of 0.3, 0.6, and 0.9%, respectively. No significant effect of dietary fennel seed supplementation was recorded on body weight, feed intake, egg production, and egg weight. Feed efficiency (kg feed per kg egg) of the 0.6% treatment group was negatively affected by fennel seed supplementation; however, kilogram of feed:dozen egg ratio was not affected when compared with the control group. The effects of dietary treatments on shape index, albumen height, albumen index, Haugh unit, yolk index, yolk colour, blood cholesterol level, and total phenol content of egg yolk had no significance. Dietary fennel seed do not affect the egg quality and blood cholesterol level of laying quail. The amount of 0.3, 0.6, and 0.9% dietary fennel seed supplementation do not have any adverse effect on performance and egg quality of laying quail.
