Evaluation of some disinfectants on total microbial load in teats cups

الملخص EN

This study was conducted at the farm of Animal Production ,College of Agriculture and Forestry- University of Mosul, to study the effect of using a number of disinfectants on Total Viable Bacterial Count (TBC) and Total Fungi (TF) on teat cups which they are a part of the automatic milking machine.The following disinfectants were used with two concentration (5 and 10 %) of Dettol; Chloroxylenol and Hydrogen Peroxide.

Water was also used at temperature at (700C).Teat cups were immersed in a bowl containing each of the above mentioned disinfectants for one minute.

The results revealed that in control treatment( without using any disinfectants) the (TBC) was 8X105 (CFU) and there was a reduction in the (TBC) after the use of the above mentioned disinfectants at 5 %, and water (700C ) they were 33X103 ; 35 X 103; 25X103; 37 X103 (CFU) respectively.

One log reduction in the (TBC) was reported after increasing the concentration of these disinfectants to 10% and they were 15 X 102; 30 X 102, 15 X 102 and 37 X 102 (CFU) respectively.

For the (TF) in teat cups there was a reduction (TF) from 4.3 X 105 in the control treatment to 5 X 102; 7 X 102 and 6X102 (CFU) after using the above disinfectants at aconcentration 5% respectively, but when disinfectant concentration were increased to10 %, there was one log reduction in (TF) to 4 X 101; 6 X 101; and 3X101 (CFU) respectively.

It could be concluded, from this study, that the best disinfectant was hydrogen peroxide in both concentration.
