ABSTRACT

The objective of this study was to examine the quality and sanitary characteristics after post slaughter period of the carcasses of chickens which fed with marine hydrobiont. A total of 240, 12 day-old broiler chickens from Ross 308 breed were used in the study. The chickens were divided into three groups as two experimental groups and a control group. The chickens in the control group were fed with basal diet (BD) during the experiment. In the first experimental group, 7% of the basal diet was replaced with mineral additive (MA) while in the 2nd group 7% percent protein mineral additive was added to the feed of chickens. The chicks were fed with these feeds from 21 to 42 days of age. During the study the broilers were constantly observed considering the disposal of feed consumption and their general conditions. The chickens were slaughtered at the end of the study and following slaughtering process morphologic and sanitary assessment of carcasses was carried out. In addition, external appearance, visceral organs and carcass samples of slaughtered chickens were checked during the veterinary inspection. The microbiological investigation were performed by using Colpoda steinii infusorium. There was no abnormal changes in organs or appearance of tissues among control and experimental groups according to the post slaughter veterinary inspection. In addition, visually examination revealed that carcasses were identical for the control group and the experimental groups. There was no difference between the control and experimental group according to microbial contamination results. As a conclusion, it is evaluated that the meat of broiler chicken in the experimental groups are safe for consuming. Therefore, it was concluded that the prepared hydrobionts could be used safely in the poultry feeding.
