Factors Contributed with The Results of Bulk Tank Analysis in Egyptian Dairy Farms.
Abstract: ABSTRACT:
Milk bulk tank analysis (BTA) is widely accepted as a useful tool for evaluating milk quality and monitoring udder health in lactating herds. It evaluates, in counts, the presence of contagious and environmental bacteria and the total bacterial count (TBC) before and after pasteurization as well as the somatic cell count (SCC).
In two years trial to study some factors that may contributed with the results of BTA, samples were taken from some cattle and buffalo dairy farms raised under different levels of hygiene and belonged to different areas in Egypt throughout the four seasons of the year in order to investigate the contribution of species, standard of hygiene, geographical distribution and seasons on such results.
Results showed higher counts of coliform _bacteria and Staphylococcus aureus in buffaloes than cows, the order that reflected on higher TBC and SCC in such species. The standard of hygiene has had also bad effect on all categories of bacteria as well as SCC. Regarding the effect of season, it was clear that the coliform bacteria, S. aureus and TBC were highest in spring while the SCC was at its highest level in summer. The contagious bacterial counts were elevated an West Delta-region while the counts of environ¬mental bacteria were higher in Middle Delta region.
