    EFFECT OF COLD-PRESS CARROT SEED OIL ON THE PERFORMANCE, CARCASS CHARACTERISTICS, AND SHELF LIFE OF BROILER CHICKENS
    (Pakistan Agricultural Scientists Forum, 2018) Urusan, H.; Erhan, M. K.; Bolukbasi, S. C.
    Present study aims to assess the effects of cold-press carrot seed oil (C SO) on performance, gut microflora, some serum biochemical parameters, meat color and meat shelf life of broiler chickens by experimenting with young broiler chicks. Accordingly, hundred fifty day-old Ross PM 308 broiler chicks were randomly given three different dietary treatments supplemented with 0 (control), 100mL/kg or 200 mL/kg (CSO). Five replicates of 10 birds each. It was observed that the supplementation of CSO led to an increase in weight gain, hot carcass and carcass yield on day 42. Addition of CSO supplement in the basal diet had no effect on serumbiochemical parameters. The number of lactic acid bacteria was higher in the group of chicks fed on the diet supplemented with 200 ml/kg CSO than in the other groups. Compared to the control group, dietary CSO supplement reduced the MDA values in leg muscles. L*(lightness) and b* (yellowness) values of the breast muscles increased in the chicks fed with 200 ml/kg CSO. Dietary 100 ml/kg CSO supplementation decreased a* (redness) values of the breast and leg muscles.In conclusion, supplementation of CSO had resulted in positive changes on weight gain,carcas yield, lactic acid bacteria count and breast tissue shelf life. As a result, this study suggests that cold-press carrot seed oil can be used as a dietary source of natural antioxidant for broilers.

    Investigation of Microbiological, Physiological and Histopathological Changes in Polymicrobial I nfection in Old Rats
    (Agricultural Research Communication Centre, 2024) Ulker, U.; Kizil, S.; Bayraktar, B.; Alcigir, M. E.; Kul, O.; Kaya, H.; Urusan, H.
    Background: The aim of this study is to examine the microbiological, clinical, physiological and pathological findings of natural polymicrobial infection developing in a wistar rat colony under long-term observation. Methods: In this study, 70 male Wistar albino rats, 3 years old, raised by conventional methods and housed in a cage environment were used. Thirteen rats with clinical symptoms such as torticollis and rotation were sacrificed for microbiological and histopathological examination after 14 days. For microbiological examination, the rapid diagnostic kit BBL Crystal system was used to identify bacterial agents in tissue and stool samples and the traditional culture method was used for isolation. Result: As a result of microbiological analysis, the rarely isolated Staphylococcus capitis ( S. capitis ) was isolated. Different Staphylococcus spp. It has been determined that the species can cause suppurative meningoencephalitis as well as septicemia in the brains of experimental animals., it is thought that polymicrobial infection will be useful for the identification of bacterial agents and infection prevention and treatment strategies.
