This study aimed to evaluate the microbiological quality of colostrum on three dairy farms with different management hygiene practices and compare it current guidelines. On farm A, was fed raw, while B C heat-treated. A feeding equipment were cleaned manually, an automated cleaning system used. Samples collected from calf submitted for microbial culture: total plate (TPC), coliforms (TCC), E. coli, enterococci, staphylococci (STAP), lactic acid bacteria counts; in addition, pH, aW, Brix...
Serum beta-hydroxybutyrate (BHB) and non-esterified fatty acids (NEFAs) are biomarkers of situations negative energetic balance in bovine. However, knowledge about their possible measurement use saliva is limited. In this report, two commercially available methods for the BHB NEFAs were validated bovine saliva. Both showed good precision accuracy. The concentrations correlated between serum, but not NEFA concentrations. cows with hyperketonemia (n = 17) had increased salivary compared to no...
This Research Communication describes, for the first time, detection of HSP70 in saliva dairy cows. Thermal stress is a major environmental that limits animal growth, metabolism, and productivity. The cellular response to heat involves synthesis shock proteins (HSPs), presumably protect functional stability cells at increasing temperatures. has been found be present cattle blood serum may also other secretory fluids, such as saliva, already observed humans. aim this study was detect protein...
Regularly weighing calves helps to assess the efficiency of rearing period and contributes animal welfare by allowing more precise feeding medication application in dairy farming, but many farmers do not weigh their regularly. Improving feasibility this process is, therefore, important. The use morphometric measurements has been used estimate weight cattle. However, studies have focused on adult animals or a wide age range. As experience allometric tissue growth, specific models for certain...
