Resumo
The aim is to find ways of management to improve reproductive efficiency of
dairy herds in recent post-partum through the use of analogues of PGF2(alfa) or
cypionate of oestradiol, which may improve uterine health and reproductive
efficiency. We used one hundred and fourteen cows girolandas randomly
divided into three groups: CON - control; PGF2(alfa) - treated with two doses (500
g) of cloprostenol in the seventh and 14th day postpartum; CE - treated with a
single application (3 mg) of estradiol, 24 hours after calving. Six animals from
each group, three primiparous cows and three cows multiparous were subjected
to blood sampling for performance of routine white blood cell count, blood
sampling intrauterine to perform endometrial cytology and bacterial meningitis.
Blood sampling occurred seven days of the date of calving, 24 hours, seven
days, 14, 21, 28, 35 and 42 days postpartum. Collection of uterine material
occur as well as in blood samples except the first (seven days before the
expected date of calving). The total lymphocyte count was different (p <0.05)
among treatments for primiparous cows and multiparous cows, with the first
group PGF2(alfa) lower than the others and the second was the best. The
primiparous cows had subclinical endometritis by endometrial cytology detected
only in group CON, while bas pluriparous CON also beyond the EC. In
primiparous cows, the CON group had a lower percentage of potentially
pathogenic bacteria (p <0.05). Primiparous cows in the EC group had a higher
percentage of pathogenic bacteria (p <0.05). The interval from
calving/conception of primiparous and multiparous cows was respectively:
CON-130,3, PGF2-176,1 e CE-161,6; CON-127,7, PGF2- 111,4 e CE-150,5.
Concluded the CON treatment and PGF2 were presented better results in
primiparous cows and multiparous cows, respectively. The economic
evaluation, the application of cloprostenol only in multiparous cows makes the
system more efficient and productive is the most economically profitable.
