- W2803187101 abstract "SUMMARY At the end of the production cycle, laying hens are intended for industrial slaughter; however, they may be also being sold to small farmers and thereby transmit pathogens under uncontrolled production practices. This study was developed with the objective of evaluating the physical characteristics of laying birds in the final cycle and investigating Salmonella presence. A total of 22 flocks of commercial laying hens over 76 wk of age were evaluated. For each flock, 20 birds were randomly selected. A total of 440 birds underwent visual evaluation of the comb, wattle, leg spur, beak, and cloaca appearance and distance measurement between the pubic bones and between the pubis and keeled sternum. After euthanasia and necropsy, ovarian follicles, liver fragment, spleen, heart, colon content, and oviduct swabs were evaluated for their normal aspects and changes. Six organ samples collected from each of 4 birds were pooled, respectively, and 24 pooled samples per flock totaled 528. Salmonella spp. were isolated in at least 2 samples from 7 of the 22 flocks (31.8%) sampled and in most of the productive birds (up to 71%). A total of 31 isolates were distributed in this way: 29.1% Salmonella Gallinarum, 19.3% Salmonella Heideberg, 16.1% Salmonella Enteritidis, 12.9% Salmonella Schwarzengrund; 9.7% Salmonella Cerro, 6.5% Salmonella Thiphimurium, 3.2% Salmonella Johannesburg, and 3.2% Salmonella Montevideo. It is concluded that individual phenotypic evaluations in laying hens over 76 wk of age can be used before birds are discarded related to end of production and phenotypic changes. The disposed, unproductive birds should not be sold to small breeders, follow-up current legislation, because Salmonella serovars have been identified. There was no correlation between asymptomatic Salmonella spp. and phenotypic alterations evaluated for disposal." @default.
