Comparing three superovulation protocols in dromedary camels: FSH, eCG-FSH and hMG.

The objective of this study was to compare three superovulation protocols in dromedary camels. Follicular waves of dromedary camel donors (n=6) were synchronized using two GnRH injections. Superovulation was initiated 2 days after the second injection (day 0 of experiment).

Superovulatory response following FSH, eCG-FSH and hMG and pregnancy rates following transfer of hatched blastocyst embryos with different diameter and shape in dromedary camel.

The objectives of this study were to compare three superovulation protocols and to investigate the effect of embryo diameter and shape on pregnancy rates in dromedary camel. In Experiment 1, following follicular wave synchronization of donors using two injections of GnRH (25 μg, im), superovulation was initiated 2 days after the second GnRH (Day 0 of experiment). Then, donors were assigned into three groups (n = 5) and received 1) FSH alone (390 mg), 2) eCG (1000 IU; single dose on Day 0) and FSH (330 mg) and 3) hMG (17.

Supplementation of tris-based extender with plasma egg yolk of six avian species and camel skim milk for chilled preservation of dromedary camel semen.

The present study was conducted to investigate a suitable source (Expt. 1) and concentration (Expt. 2) of plasma egg yolk (PEY) and concentration of camel skim milk (CSM; Expt.

The effect of polymorphism in gene of insulin-like growth factor-I on the serum periparturient concentration in Holstein dairy cows.

Objective: To investigate the relationship between polymorphism within the 5'-untranslated region (5'-UTR) of IGF-I gene and its periparturient concentration in Iranian Holstein dairy cows.

Methods: Blood samples (5 mL, n = 37) were collected by caudal venipuncture from each animal into sample tubes containing the EDTA and DNA was extracted from blood. In order to measure IGF-I concentration the collection of blood samples (n = 111) was also done at 14 d before calving (prepartum), 25 and 45 d postpartum.
