Concentrations of toxic heavy metals and trace elements in raw milk of Simmental and Holstein-Friesian cows from organic farm
Concentrations of toxic heavy metals (cadmium (Cd), lead (Pb)) and major nutritional and trace elements (Ca, Mg, P, Cu, Fe, Mn, Se, Zn) were analyzed in the milk of Simmental (n = 20) and Holstein-Friesian (n = 20) cows from an organic farm. Elements were determined using inductively coupled plasma emission atomic spectrometry. The conducted research showed that the milk of Simmental cows was c...

متن کاملBacteria Counts in Raw Milk
There is little doubt that raw milk is the most scrutinized agricultural commodity. Appendix N of the Pasteurized Milk Ordinance requires that all bulk tank milk be tested for beta-lactam antibiotics. This document also sets the regulatory levels for somatic cell counts (SCC) and bacteria levels in raw bulk tank milk. Milk processors are required to perform the regulatory testing. Many progress...
متن کاملMilk quality, manufacturing properties and blood biochemical profile from dairy cows fed peas (Pisum sativum L.) as dietary protein supplement
Pea (Pisum sativum L.), a protein-rich legume seed well adapted to many climatic areas and widely used for feed and food, was fed to Italian Friesian breed cows for 16 weeks to assess its effects on milk yield and production, renneting properties and metabolic responses. Cows within each group were assigned to two isonitrogenous and isoenergetic concentrates based on corn plus soybean meal or p...
متن کاملIncidence of Listeria spp. in Dairy Cows Feed and Raw Milk in Latvia
Feed is a risk factor for poisoning the farm environment thus also fresh milk with pathogenic microorganisms of Listeria genus species. Listeria ivanovii, Listeria innocua, and Listeria seeligeri were isolated from 9.2%, but Listeria monocytogenes from 20.0% of feed samples. Most often different fodders (9.3%) and silage (4.7%) were contaminated with Listeria monocytogenes. Listeria genus speci...
