    Besi danalarında ortalama karkas ve parça et verimi üzerinde araştırmalar
    (Uludağ Üniversitesi, 1988) Berker, Aşkın; Uludağ Üniversitesi/Veteriner Fakültesi.
    In this study, the average body weights, skin, bone weight percentages and the loses due to freezing, the total loses, boneless meat, visceral organs and the meat percentages obtained from 34 fattening calves belonging to our pilot fattening unit of Faculty of Veterinary Medicine of Uludağ University, and were scientifically and statistically evaluated by us at the Department of Food Hygen and Technology of the same faculty. They were slaughtered at the Meat Plant of the Meat and Fish Processing Center in Bursa, and were cooled and cut into desired pieces for marketing. The average body weights of carcasses was 305.47 kg, the bone weights 54.2 kg., the whole skin weight was 46.5 kg, the freezing lose was 1.39 %, the bone proportion over the slaughtering weights 18.36 %, the boneless meat performance 43.70 %, the proportion of visceral organ weight over the body weight 34.24 %, and the sum of the processing loses was 3.07 %. The percentages of products like ground meat, cube cuts, steak, rosto, weal chups, contrfilet and file mignon were 36.66, 16.66, 11.26, 1.35, 2.61, 2.25 and 1.62 percent respectively.

    (Uludağ Üniversitesi, 1988) Minbay, Ahmet; Erdinç, Hüseyin; Berker, Aşkın; Uludağ Üniversitesi/Veteriner Fakültesi/Mikrobiyoloji Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Besin Hijyeni ve Teknolojisi Anabilim Dalı.
    Today, one of the important problems concerning public health is ensuring a balanced and adequate nutrition of the society. On the one hand, it is necessary to increase the production of food in order to feed the society in a sufficient and balanced way, and on the other hand, it is necessary to ensure that nutrients are delivered to the consumer in healthy conditions. The fact that the foods consumed are reliable in terms of human health is among the most striking news all over the world and in our country. Food control and technology in the modern sense requires the detection of microorganism drug and toxic substance residues, which are likely to be present in foodstuffs, on routine examinations. In this article, the usage purposes of antibiotics used especially in the breeding of livestock and the effect of this use on human health will be emphasized. Antibiotics, as a general definition, are substances that are formed by a microorganism and prevent them from harming animal and human health by killing other microorganisms or preventing their reproduction. Antibiotics give successful results in the treatment of many infectious diseases of animals and humans, which are primarily caused by bacterial factors. In recent years, antibiotics that are successful in the treatment of parasitic, fungal and viral infections have been obtained in addition to bacterial infections. The drugs to be used in the treatment of infectious diseases in humans and animals, directly affecting the disease agent, and not harming the health of the treated person or animal is a feature that is primarily sought. The first successful, specific effective substance in the history of medicine was a synthetic organic compound containing arsenic, which was introduced as the "magic bullet" by Paul Ehrlich at the beginning of the 20th century. Although this compound, which is effective in the treatment of syphilis and other spirochetal infections, is promising, it could not deliver what was desired due to its side effects. In the 1940s, the period of use of antibiotics against many infectious diseases affecting human and animal health began and with this period, the possibility of more effective control and treatment of infectious diseases was born. Discovered by Alexander Fleming in 1929, penicillin was started to be produced for commercial purposes in the 1940s and the first antibiotic that gave successful results in the treatment of various infectious diseases was found. Intense research has been done on antibiotics in the period that has passed until today. As a result of these studies, many new antibiotics have been found and they have found wide application areas in the treatment of bacterial, viral, fungal and parasitic diseases of humans and animals, infectious diseases, prevention and growth accelerators in animals.

    Salamura beyaz peynirlerde olgunlaşma sırasında görülen mikrobiyolojik ve kimyasal değişiklikler
    (Uludağ Üniversitesi, 1988) Berker, Aşkın; Uludağ Üniversitesi/Veteriner Fakültesi.
    In this study, during the 90 days of ripening period, the microbiological and chemical changes occurred in white cheeses prepared under practical conditions were investigated microbiological and chemical analysis were made on the samples taken on 1, 7, 15, 30, 90 th days of ripening period. The counts for total microorganism were found to be decreased from 1.8x10⁸ to 1x10⁷ germs/g, for coliforms from 1.6x10⁷ to 4x10⁵ germs/g during the 90 days of ripening. During the same period the counts of fungus did not change markedly (5.7x10³ - 5x10³). The range of pH changed from 5.1 to 4.9. The amount of ıalt and fat was determined as 4.25%- 4.31 % and 20 % - 20.68 % respectively. Acidity changed from 0.59% to 0.88 %. Relative humidity was determined as 54.33 % - 54.92. Staphylococcus aureus and Salmonella species was not isolated from any of the samples examined.
