Mineral elements (Ca, Na, K, Mg, Zn, Ti, Sr, Fe, Ni, Ba, Cr, Mn, Cu, Se, Cd, Mo, B, V, As, Pb and Hg) in Provola cheeses obtained from dairy cows fed with two different integrated diets (Biotrak) and without olive cake (Control) were determined to discriminate between the two different cheeses. The ...

Zinc, copper and manganese are essential nutrients in farm animals nutrition and must be provided by feed rations. Trace mineral deficiencies adversely affect growth performance and health status. Formerly microelements deficiencies were a relevant issue in livestock farming. Nowadays, researchers...

One strain of Lactobacillus was isolated from the fermentation broth of traditional fermented grain and identified as Lactobacillus sakei by physiological and biochemical tests, colony and strain morphological observation, and 16S rRNA sequencing. The composition of MRS medium as the basal medium...

In this study, a new method was developed for the extractive pre-concentration/detection of trace Mn in milk prior to analysis by UV-spectrophotometry. The method is based on the pH-controlled intra-ligand charge transfer (ICT) complexation of modifier, 2-HBT in presence of trace Mn (II), and then...

In this experiment, the contents of potassium, sodium, calcium, magnesium, copper, iron, manganese and zinc in animal feed were determined by two processing methods, wet digestion and dry ashing, combined with atomic absorption spectrometry. The content of elements in corn [GBW10012 (GSB- 3)] was...

The article reflects data on the positive effect of organic manganese on methanogenesis and metabolic processes in the rumen of bulls. It was found that the introduction of manganese at a dose of 4,0 g per 1 kg of dry matter in a sample with bran to a greater extent reduced the production of metha...

Struvite production can recover ammonia and phosphorous from digested wastewater as fertilizer. During struvite generation, most of the heavy metals was co-precipitated with ammonia and phosphorous into struvite. Understanding the precipitation behavior of heavy metals with suspended solids (SS)...

Attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy is an essential tool for the determination of mineral chelation in proteinates used as animal feed additives. With advances in feed formulations and stringent regulatory requirements to confirm the degree of chelation...

Effect of varying levels of organic zinc and manganese on performance, hepatic tissue and tibia proximate compositions of finisher broiler chickens were evaluated. A total of 360 heads of mix sexed of day-old chicks of broiler chickens in which at 4 weeks of age were allotted to 9 dietary...

Bacterial proteases have extensive applications in various fields of industrial microbiology. In this study, protease-producing organisms were screened on skimmed milk agar media using serial dilution. Through microbial biomass production, biochemical tests, protease-specific activity, and 16 s RNA ...
