چکیده

The study aimed to assess the quality attributes of set yoghurt made from cow's milk preserved by lactoperoxidase system (LPs). Fresh was collected Datto collection center and samples were grouped control LPs activated. Set prepared immediately for controlled samples, but in activated milk, sample kept 9 h at 25 °C ± 2 before made. LP enzyme within after milking adding 1 mg/ml sodium thiocyanate (SCN_) hydrogen peroxide (H2O2). Totally, 36 L used experiment done triplicates. Titratable acidity (TA) pH assessed every 30 min until coagulation formed. Yoghurt stored 21 days different parameters including incubation duration, pH, TA, microbiological sensory attributes. results revealed that partially suppressed rate acid production during cultured milk. treated had significantly (P < 0.05) higher lower TA values. Similarly, total bacterial counts 24-h, 72-h 7-days storages. Additionally, yeast mold 24-h 7-days. received better scores In general, can be making without a negative effect. Further studies are needed illustrate fitness other products.

Immunological attributes of blood and milk neutrophils isolated from crossbred cows during different physiological conditions

The goal of this work was to understand how polymorphonuclear leukocytes (PMN), the first line of cellular defence, integrate and prioritize multiple chemotactic signals to navigate during periods of demand like subclinical mastitis (SCM), clinical mastitis (CM), pregnancy (P), and calving (C). For this, blood and milk samples were collected from five groups of crossbred cows (healthy, with SCM...
