Sciences VétérinairesTags : Stress pré-abatage Transport Abattage Abattoir Qualité Viande Bovin Pre-slaughter Transportation Slaughter Slaughterhouse Meat quality cattle ??????? ??? ????? ????? ????? ???? ???? ?????? Index. décimale : 636 Sciences Vétérinaires Résumé :
The sensory and technological qualities of the meat depend on the conditions of
development of muscle metabolism at the time of slaughter. These later are largely influenced by the physiological state of the animal especially the potential stress reactions.
We were interested on the effects which relate the pre-slaughter procedure and the
characteristics of animals (breed, age, sex) on the level of stress in cattle and the early post mortem muscle metabolism. Therefore, the study was carried on two main slaughterhouses;one in the Bejaia department and the other in Setif. The samples were taken from a farm, For the pH measurement, and post-mortem temperature; they were carried out one hour after the slaughter, then every half an hour, to two hours and a half.
Stress levels expressed by the cortisol concentration are greater in animals of the local breed, and females. The most factors involved in animal stress are: transport, but also the deprivation of food associated with set expectations at slaughterhouses. In the section based on stress and energy metabolism, it has been demonstrated the effect of age. Thus, our results showed that the combination of stress and physical activity in the hours preceding slaughter, can induce early postmortem pH lowering values with early post mortem higher temperatures.
Furthermore, high levels of stress after prolonged hold, associated to the deprivation of food, induces high early postmortem pH values with early lower post mortem temperatures.
In comparison to other researches done in other countries, the results are sustained by certain and do not conform to others. This heterogeneity of the results is due to differences in the animal (breed, species), of farming (feeding, intensive or extensive farming), slaughtering procedures, the study itself (applied protocol and number studied factors and parameters).

Sciences VétérinairesTags : Paratuberculose bovin abattoir Constantine histopathologie paratuberculosis cattle slaughterhouse histopathology ???? ???? ??????? ?????? ??????? ?????? Index. décimale : 636 Sciences Vétérinaires Résumé : Bovine paratuberculosis is an infectious and contagious chronic disease due to the increase of the mycobacterium M paratuberculosis in the organism. This disease is widespread in all countries practicing intensive cattle raising and causes heavy economic losses.
The objective of this study is to search for paratuberculosis in cattle slaughterhouses. The author begins by presenting anatomical and histological reminders of the intestine and the satellite lymph; the major epidemiological elements of the causative pathogen, the symptoms and lesions of paratuberculosis plus the different methods of diagnosis and screening are described.
The practical part consists of visits to the slaughterhouse, to inspect the intestines, take samples from the mesenteric hypertrophied lymph, accompanied by a portion of the intestine, and send them to the laboratory for histopathological study.
Two stains were made, the HE and cold Ziehl stain; impressions of intestines and mesenteric lymph are also colored by the Ziehl-Neelsen hot method and examined microscopically.Diplôme : Magistère En ligne : ../theses/veterinaire/GHE6452.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9487 La paratuberculose bovine dans les abattoirs de la region de Constantine [texte imprimé] / Dounia Gherroucha ep Beziez, Auteur ; L Benhamza, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2014 . - 181 f. ; 30 cm.

Index. décimale : 636 Sciences Vétérinaires Résumé : To assess the health of the slaughterhouse in El Oued and the hygiene of slaughter processes, our study focused on the flora of surface contamination of carcasses camel bacterial and fungal.
The flora is the predominant flora aerobic mesophilic total (1.79 log10 cfu/cm2, 57%) followed by enterobacteria (0.84 log10 cfu/cm2; 27%) and fecal coliform (0.50 log10 cfu / cm2, 16%).
The contamination rates are significantly lower than those recorded on beef carcasses (2.76 log10 cfu / cm2 for flora aerobic mesophilic total; 2.16 log10 cfu / cm2 for Enterobacteriaceae and 1.66 log10 cfu / cm2 for fecal coliform), And sheep (3.08 log10 cfu / cm2 for flora aerobic mesophilic total, 2.90 log10 cfu / cm2 for Enterobacteriaceae and 2.72 log10 cfu / cm2 for fecal coliform).
To study fungi, we have identified five molds (Penicillium sp 28 times or 41.18%; Cladosporium sp 20 times or 29.41%; Mucorales sp 11times or 16.18%; Aspergillus niger 5 times or 7.35% and Alternaria 4 times or 5.88%) and six yeast (Rhodotorula rubra 25 times or 44.64%, Rhodotorula glutInis 13 times or 23.21%, Geotrichum sp 11 times or 19.64%, Torulopsis sp 4 times or 7, 14%, Cryptococcus neoformans 2 times or 3.57%, and Cryptococcus sp 1 time or 1.79%)Diplôme : Magistère En ligne : ../theses/veterinaire/HAM5298.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=1864 Contribution à l'étude de la contamination superficielle bacterienne et fongique des carcasses camelines au niveau de l'aattoir d'El-oued [texte imprimé] / Brahim Hamad, Auteur ; Miriem Aissi, Directeur de thèse ; K.
