Abstract
Introduction. At the end of milking of the bovine
female, the teat sphincter remains open and
expanded for about 30 to 60 minutes. This time
favors the entry of environmental microorganisms
into the mammary gland, causing new infections
and compromising the health of the cow.
Objective. Bactericidal disinfectants used, such
as iodine to prevent entry of microorganisms
into the mammary gland after the milking
routine, can easily be inactivated by contact with
milk, manure, mud and urine; the nipple then
remain unprotected and exposed to the entry of
different microorganisms. The protective effect
of artificial barrier sealant in dipping post-milking
routine prevents the contact of the nipple with
environmental microorganisms. Materials and
method. The effect of a teat dip artificial barrier
sealant was evaluated on the post;dipping in a
mechanic milking routine preventing the contact
between microorganisms and the nipple after
the milking. Also the sealant forms a film on the
nipple preventing the entry of bacteria into the
udder. Two groups of animals (25 per group)
were selected, a group was treated with the
artificial barrier dipping in the post-milking period
and in the control group was perform the normal
routine process. In each group the hygienic
quality was tested by Colony Forming Units
(CFU/mL). Randomness, independence and
normality of experimental errors, homogeneity of
variance associated with the effects of variables,
independence of action and variances: attached
to the model assumptions were validated.
There was perform descriptive statistics and
ANOVA using SAS 9.0 software. Results. It was
demonstrated that de use of a barrier protector
decreases the amount of bacteria on the nipple
surface in the moment of the milking routine.
