Aflatoxin B1 (AFB1) belongs to a group of hepatocarcinogenic and hepatotoxic mycotoxin produced by Aspergillus flavus and Aspergillus parasiticus found in food or feed products. In this study we analyzed 180 feed of six different brands of commercial poultry feeds from three feed distribution outlets in Ibadan, southwest Nigeria for the occurrence and concentrations of AFB1. In addition, to the transfer of AFB1 to broiler meat from chicken fed for four weeks with one brand of feed associated with the highest AFB1 contamination. The study was carried out between April and June, 2019. The presence/concentration of AFB1 was determined using High Performance Liquid Chromatography (HPLC) following solid phase extraction of sample and preparation. Aflatoxin B1 was detected in all (100 %) the brands of feed and 48 % of chicken samples tested. The concentration of AFB1 in feed ranged between 10.5 ± 4.0 and 47.78 ± 6.4, while the mean AFB1 residues obtained in chicken muscle, gizzards and liver after four weeks were 0.07 ± 0.02, 0.18 ± 0.05 and 0.13 ± 0.02 μg/kg, respectively. The presence of AFB1 in all the brands of poultry feeds tested in this study and its possible transfer into chicken meat poses food/feed safety and public health concern. There is therefore, the need to screen feed and apply Hazard Analysis Critical Control Point to feed manufacturing, storage and broiler chicken production to prevent aflatoxicosis.

Newcastle disease is an acute fatal disease of poultry. The aim of this study was to determine the dynamics of the transmission of avian avulavirus (velogenic viscerotropic Newcastle disease-genotype VIId) from either intramuscularly (IM)- or intranasally (IN) infected 8-week-old Egyptian Baladi pigeons in contact with commercial Arbor Acres broiler chickens (4 weeks of age). The mortality of IM infected chickens and pigeons was 10/10 for chickens and 8/15 for pigeons, while the mortality of IN infected chickens and pigeons was 7/10 for chickens and only 1/15 for pigeons. The concentration of viral shedding in the oropharynx was higher than that in the cloaca for both IN and IM infected pigeons. Pigeons infected IN continued shedding the virus from the oropharynx from the 4th day post-infection (dpi) up to the 16th dpi, while IM infected pigeons stopped oropharyngeal shedding at the 11th dpi. Chickens in contact with infected pigeons developed severe respiratory, digestive and nervous signs. The mortality rates in chickens in contact with IM and IN infected pigeons were 2/5 and 3/5, respectively. Chickens in contact with IM infected pigeons showed higher viral shedding titres in both the oropharynx and cloaca than chickens in contact with pigeons infected IN. In conclusion, free-range pigeons are considered an efficient carrier and transmitter of NDV-VIId compared to commercial broiler chickens raised in open houses.

Newcastle disease (ND) remains one of the most harmful poultry diseases that threaten the poultry industry producers all over the world, thus the present work was planned to investigate the hematological, biochemical, and pathological changes in vaccinated and non-vaccinated broiler chickens naturally infected with ND. The study was conducted on 45 broiler chickens, 35-days-old, from a private farm in Damietta governorate and used in this work, 15 chickens were clinically healthy (Group I), 30 chickens with ND symptoms divided into 15 non-vaccinated (Group II) and the other 15 chickens (Group III) were vaccinated with La Sota strain of NDV with a titre of 106.5 EID50. The disease was diagnosed by hem agglutination test as ND. Blood and tissue samples were collected for clinical-pathological and histopathological examination. The infected broiler chickens showed cyanosis, nasal discharge, edema of eyelid and white pasty diarrhea with nervous manifestations. Furthermore, microcytic hypochromic anemia with leukocytosis was observed. Biochemical studies revealed a significant decrease in serum total proteins, albumin and A/G ratio, with significant increases in serum activities of aspartate aminotransferase, creatinine, and uric acid and glucose concentration in addition to several histological alterations were significantly seen in brain, intestine, liver and kidney of the infected birds. All these disturbances were less severe in the vaccinated group than the non-vaccinated one. In conclusion, La Sota vaccine can increase the bird resistant against Newcastle disease virus induced blood disorders and hepatic-renal insufficiency in broiler chickens.
