| Abstract | ||
| This study aimed to evaluate the effect of pre-milking teat preparations (Iodine and Hydrogen peroxide) on incidences of mastitis, SCC, the prevalence of (Staphylococcal, Streptococcal and Coliform) infections and total bacterial count of milk in addition to measurement of iodine residues in milk and assessment the status of teats after using hydrogen peroxide. This study was performed on 75 cows, divided into 3 groups. The first group (25 cows) iodine 0.5% was used as pre-dipping disinfectant; the second group (25 cows) hydrogen peroxide (Hydroxil 0.5%) was used as pre-dipping disinfectant while the third group (20 cows) was control group. Results showed that, pre-dipping had an effective role in decreasing the incidence of subclinical mastitis either iodine was used or hydrogen peroxide as pre-dipping disinfectants and also SCC was decreased.The incidences of microorganisms (Staphylococcus spp., Streptococcus spp. and Coliform) isolated from examined milk samples were decreased after pre-dipping procedure of the teats. Iodine residues after pre-dipping were in normal range and not exceed the permissible limits. When hydrogen peroxide was used as pre-dipping disinfectants it may lead to cracks on the teats and that considered as predisposing factors to occurrence of mastitis. Generally pre-dipping preparation of the udder should be recommended to be followed in dairy farms | ||
