Superovulation and embryo quality with porcine follicle stimulation hormone (pFSH) in Katahdin hair sheep during breeding season
Estrus synchronization of 21 ewes was carried out using intravaginal sponges (60 mg of medroxyprogesterone acetate, Sincrogest®-Sanfer, Mexico) for 14 days. 7 ewes were randomly assigned to one of the three treatments: T1, 80 mg; T2, 120 mg; T3, 140 mg of porcine follicle stimulating (pFSH) (Foll...

| description | Estrus synchronization of 21 ewes was carried out using intravaginal sponges (60 mg of
medroxyprogesterone acetate, Sincrogest®-Sanfer, Mexico) for 14 days. 7 ewes were randomly
assigned to one of the three treatments: T1, 80 mg; T2, 120 mg; T3, 140 mg of porcine follicle stimulating
(pFSH) (Folltropin-p®-Bioniche, Canada) administered on day 12 after sponge insertion. The dose was
divided in decreasing doses; second and third day representing 50 to 75% and 25 to 33% of the first day
dose, respectively. At the beginning of superovulation treatment, each ewe received 5 mg of dinoprost
tromethamine (1 ml of Lutalyse® Pfizer, Mexico). An effect of pFSH level was observed on the interval
from sponge removal and the onset of estrus (REI) (P < 0.01), with a difference of 13.5 h between ewes
from treatment 2 and 3. The number of follicles (F), number of collected embryos (CE) and transferable
embryos (TE) (P < 0.05) was also different among treatments, with highest values observed in T3 (3.0 ±
0.6 for CE and 2.3 ± 0.5 for TE). Embryo recovery rate was in average 66.5%, (P > 0.05) of CL observed.
Further investigation is guaranteed to evaluate the effect of pFSH doses on estrus synchronization for
selected breeding seasons |
