This study was carried out to investigate the possible for utilization of garbage in pig feed by investigating the functional characteristics of pork from pigs fed dried citrus byproduct. The samples consisted of the pork loin from pigs not fed with dried citrus pulp (DCP-0) and fed with 6% and 10% dried citrus pulp during growing and fattening period (DCP-1) there is no respective comparison here The pH, VBN content, TBARS value, bacterial counts, surface color, water holding capacity, loss degree and rheological properties of the samples were determined by physicochemical properties, and the sensory scores were evaluated. The pH, VBN content, surface color, water holding capacity and loss degree were not different between the samples, but the TBARS value and bacterial counts of DCP-1 were significantly lower than those of the DCP-0 (p<0.05). The cohesiveness, gumminess, chewiness, shear forte value, taste, flavor, tenderness, juiciness and palatability were not different between the samples, but the hardness of DCP-0 was higher than that of the DCP-1 and the springiness of DCP-1 was higher than that of the DCP-0 (p<0.05).

African swine fever (ASF) is a fatal viral disease in pigs, with a short incubation period and causing immediate death. Few studies exist on the Asian epidemic ASF virus (ASFV) challenge in older pigs, including growing and fattening pigs and sows. We aimed to investigate clinical outcomes, pathomorphological lesions, and viral distribution in organs of 3-month-old growing pigs that were inoculated with the ASFV isolated in Vietnam. The clinical outcomes were recorded daily, and the dead or euthanized pigs immediately underwent necropsy. Viral loads were determined in 10 major organs using quantitative polymerase chain reaction. The average incubation period in growing pigs was more delayed (5.2±0.9 dpi) than that in weaned pigs, and the clinical signs were milder in growing pigs than in weaned pigs. The digestive and respiratory clinical signs in growing pigs showed at the end period of life, but these were observed at an early stage of infection in weaned pigs. The pathomorphological features were severe and nonspecific with hemorrhagic lesions in various organs. The viral loads in organs from growing pigs were higher than those from piglets, and the number of viral copies was related to gross lesions in the tonsil and intestine. In the absence of vaccines against ASF, early clinical detection is important for preventing the spread of the virus. Our findings elucidated that the clinical signs and gross lesions in growing pigs differed from those in weaned pigs, which provide valuable information for diagnosis of pigs with suspected ASF infection.
