ABSTRACT This study was conducted to determine the effect of diets containing different levels of thyme essential oil (TEO) on performance, some serum parameters and the antioxidative metabolism of the serum and liver tissues in quails. A total number of 200 sixteen-days-old Japanese quails (Coturnix coturnix japonica) were used in the study. The animals were divided into 4 groups; the control group was fed only basal diet but groups TEO1, TEO2 and TEO3 had thyme essential oil of 150, 300 and 450 mg/kg, respectively, added to their diets. Body weight and daily weight gain increased with higher levels of thyme essential oil in the feed, yet a statistically significant increase was detected in only group TEO3 (p<0.05). Furthermore, in all of the groups... |

ABSTRACT Fucoxanthin is a major carotenoid found in marine brown algae. This study investigated the impact of fucoxanthin on the growth performance, antioxidant metabolism and meat quality of broilers. Overall, 180 one-day-old male broiler chicks (Ross 308) were assigned to one control group (CONT) and 2 treatment groups (FUCO1 and FUCO2), with six replicates of 10 birds each. The CONT, FUCO1 and FUCO2 birds were fed a basal diet supplemented with 0, 100 and 200 mg/kg of fucoxanthin, respectively. Average body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) were similar among the groups. Fucoxanthin increased catalase (CAT) and superoxide dismutase (SOD) activities and glutathione (GSH) levels (p<0.01), and reduced malondialdehyde... |

ABSTRACT Heat stress, causes economic losses and has negative effects on both broiler husbandry and animal welfare. Nutritional strategies are applied for minimizing the negative effects of heat stress. In the present study, at the finishing period (24-39 days of age) of heat stress, the effects of diet involving 21% and 19% proteins and vitamin E on lipid metabolism and antioxidant mechanism of action, aimed to be identified. This study was carried out in six groups as: HPC (24oC heat + 21% crude protein (CP)), HPS (34oC heat + 21% CP), LPC (24oC heat + 19% CP), LPS (34oC heat + 19% CP), HPSVE (34oC heat + 21% CP + Vitamin E) and LPSVE (34oC heat + 19% CP + vitamin E) groups. Superficial pectoral muscles (breast) and liver tissues were used for oxidative... |

ABSTRACT Mycotoxins, which are produced by some fungi under improper storage conditions before or after harvesting in plant products, cause acute or chronic toxicities. Ochratoxin A (OA) which is also one of the harmful mycotoxins pose a threat to animal and human health. This study was carried out in order to determine OA levels in mixed feed and feedstuffs materials used in livestock enterprises throughout Sivas province. The 59 mixed feeds and 30 feedstuffs materials collected from different enterprises was analysed. Ochratoxin A concentrations were quantified using immunoassay (ELISA). In result, OA was found to be positive in 64 (71.91%) of the 89 samples analysed, whereas OA was not found in 25 samples (28.09%). |

ABSTRACT Tibial dyschondroplasia (TD) is a skeletal disorder that occurs in the proximal metaphyses of tibiotarsus and sometimes tarsometatarsus, resulting in the development of avascularized and non-mineralized abnormal cartilage and causing significant economic loss. In this study, we aimed to show the histopathological changes and the relationship between the release of Heat-Shock Protein 27 (HSP-27) and oxidative DNA damage in broiler chickens with tibial dyschondroplasia, using histopathologic and immunohistochemical methods. Our study material consisted of totally 20 animals out of 42 days old 205 Ross 308 broiler chickens, 10 with TD lesions and 10 healthy control subjects. Tissue samples taken from animals performed necropsy was exposed to routine... |
