Estrus Synchronization of Replacement Gilts Using Estradiol Cipionate and PGF and Its Effects on Reproductive Outcomes.

In this study, we evaluated the effectiveness of using estrogen-induced prolonged luteal function followed by prostaglandin F2 alpha (PGF2α) treatment to synchronize estrus in gilts. On day12 of the estrus cycle (D0 = first day of standing estrus), 52 gilts were assigned at random to two experimental groups: non-treated gilts (CON, n = 22), serving as controls, and prolonged luteal function group (CYP, n = 30), receiving a single treatment with 10 mg of estradiol cypionate intramuscularly Starting on day 12, blood samples were collected for estradiol and progesterone assays. Estrus detection started on day 17.

[Utilization of the Famacha method in individual clinic diagnostic of haemonchosis in sheep of south-west of Minas Gerais State].

The aim of this study was to evaluate the efficacy of Famacha method in individual clinical diagnosis of haemonchosis in sheep from the south-west of Minas Gerais. Fifty crossbred Santa Inês ewes were evaluated during 5 months as for conjunctival mucous colour (Famacha method), Packed Cell Volume (PCV), Faecal Egg Counts (FEC), body score and clinic alterations. The score Famacha observed was from 1 to 3, the body score from 2 to 5, the PCV from 20 to 47%, and FEC from 0 to 7,750.
