in a completely randomized design, the effect of four iso-protein and iso-caloric diets containing different levels (0, 8, 16 and 24%) of processed broiler litter was studied on the fattening performance of 60 holstein male calves (with initial weight of 309±9kg and about 8-9 month age) for a period of 200 days. at the end of the experiment, all animals were slaughtered and then the carcasses, ...

A poultry-processing model for a quantitative microbiological risk assessment (QMRA) of campylobacter is presented, which can also be applied to other QMRAs involving poultry processing. The same basic model is applied in each consecutive stage of industrial processing. It describes the effects of inactivation and removal of the bacteria, and the dynamics of cross-contamination in terms of the ...

Salmonella attached to the poultry skin is a major source of carcass contamination during processing. Once attached to the poultry skin, it is difficult to detach and inactivate Salmonella by commonly used antimicrobial agents since the pathogen is entrapped deeply in the feather follicles and the crevices on the skin. Essential oils could be natural, safe, and effective alternatives to synthet...

Mapping the number and distribution of Salmonella on poultry carcasses will help guide better design of processing procedures to reduce or eliminate this human pathogen from poultry. A selective plating media with multiple antibiotics (xylose-lysine agar medium [XL] containing N-( 2-hydrox yethyl)piperazineN'(2ethanesujfonic acid) and the antibiotics chioramphenicol, ampiciflin, tetracycline, a...

Background & objectives: Nowadays, consumers are demanding more accurate and clear food information than ever before, and meat products are no exception. Given the relatively high cost of raw meat, the possibility of adulteration is not unthinkable. The importance of detecting fraud meat products is due to the inclusion of other types of meat or cheap carcass components or the non-compliance of...

Different unconventional feed stuffs are used in poultry production to decrease ration cost and the environmental, nutritional economic benefits derived from maximal utilization of animal blood. This study was established assess effect partially replaced dried blood content supplemented on growth performance responses carcass. In a feeding trial, 240 commercial broiler chicks day old, with an a...
