We studied native Mertolengo cattle to evaluate superovulatory (SOV) treatments,
subsequent fertility of donors and pregnancy rate of recovered embryos. In Experiment 1 we …

This study was conducted to compare the superovulatory (SOV) response of dairy cows (n=
172) and heifers (n= 172), with two SOV treatments started at the mid-luteal-phase of the …

This study evaluated embryo production after superovulation (SO) with a reduced number of
FSH applications and increased eCG dose in 26 Bos taurus× Bos indicus donors. On Day 0 …

Forty-two Holstein heifers were superovulated with FSH-P (total dose, 30 mg) and
cloprostenol. Treatment was initiated on Day 3 (Group D3, n= 11), Day 6 (Group D6, n= 11) …

Dairy (Bos taurus) heifers and cows (n= 40) in a tropical environment were treated during
mid-luteal phase using either SUPER-OVR or OVAGEN™ to induce superovulatory …

Abstract 29 Holstein× Bos taurus crossbred cows were superovulated with FSH (40 mg) in
the hot-dry, hot-humid and winter seasons. The response to superovulation was highest in …

Response to superovulation, fertilization rate, production of viable embryos and fertility
subsequent to superovulation were evaluated in Mertolenga cows treated with two follicle …

Compared to Bos taurus breeds, Bos indicus breeds of cattle present several differences in
reproductive physiology. Follicular diameter at deviation and at the time of ovulatory …

The effect of multiple ampules of frozen semen on conception rate in superovulated Holstein
heifers was studied using 3 breeding regimens (n= 25): 1 ampule at 12 hr (0 hr= beginning …

We aimed with the present study to evaluate the effects of FSH treatment (200 mg) split in
four or six administrations on ovarian follicle stimulation and in vitro oocyte competence for …
