| The effects of different dietary lipids on the fatty acid profiles of eggs produced by 20 and 54 wk old Dekalb laying hens were investigated. Laying hens were subjected to three defined treatments according to the source of lipid added to their diets: soybean oil, beef tallow, and a control diet (without the addition of oil). The experimental design was in a 3x2 factorial arrangement (three treatments and two different ages). The fatty acid composition of the yolks in the eggs produced by the laying hens was analyzed. The eggs produced by laying hens on the soybean oil diet had a large amount of polyunsaturated fatty acids (PUFA) omega-6 (n-6) and omega-3 (n-3) in their yolks (23.55, 2.30% respectively), whereas egg yolks from hens who were given beef... |

| ABSTRACT: In order to detect and identify Campylobacter spp. in broiler chicken carcasses, and to compare detection methods, 43 chilled and 43 frozen carcasses were collected and analyzed. Three methodologies were evaluated: an automated Enzyme Linked Fluorescent Assay (ELFA) VIDAS®30, Polymerase Chain Reaction (PCR) and real-time PCR. Only four chilled carcasses (4.6%) were considered positive for Campylobacter spp. by VIDAS®30 and no sample was positive when the conventional PCR technique was used. However, real-time PCR showed a higher incidence of contamination by Campylobacter spp. in broiler carcasses, with 45 (52.3%) positive samples. C. jejuni was the species most frequently reported in the samples (88.8%). No differences in the frequencies of... |
