ABSTRACT.- In order to assess the effect of equine chorionic gonadotropin (eCG) administered on Day 5 or 7 of a fixed-time artificial insemination protocol (FTAI) in anestrous suckled beef cows, two experiments were performed to determine the following endpoints: Experiment 1 (n = 22), preovulatory follicle (POF) diameter, ovulation time, corpus luteum (CL) area, estradiol (E2) and progesterone (P4) concentrations; and Experiment 2 (n = 676), a field trial to evaluate conception rate using the same experimental design. In both experiments, a synchronization protocol using estradiol benzoate (EB) (Day 0), intravaginal progestin device (IVD) (Days 0 through 7), prostaglandin (PGF) (Day 7), eCG (Day 5 or 7), and GnRH (Day 9). Treatment consisted of administering 400 IU of eCG on Day 5 (T5) or Day 7 (T7 or control) concomitant with treatment with PGF2α. In experiment 1, all cows of T5 ovulated by 16 h after GnRH administration. The POF tended (P = 0.06; P = 0.07) to be larger at 1 and 2 d before ovulation in T5. The day before ovulation, E2 tended to be lower (P = 0.06) in T5 compared with T7. The CL area and the P4 concentrations were greater (P = 0.04) on day 9 in T5 compared with T7. In experiment 2, the conception rate was greater (P = 0.04) in T5 (72.2%) compared with T7 (61.0%) group. Therefore, administration of eCG on Day 5 of the designed protocol hastened ovulation of a greater follicle, which produced a larger CL and greater concentrations of progesterone by Day 9 after ovulation, resulting in 11.2% increase in cows pregnant. © 2022 Elsevier Inc.

Wheat stem rust, a devastating disease of wheat and barley caused by the fungal pathogen
Puccinia graminis f. sp. tritici, was largely eradicated in Western Europe during the mid-to-late
twentieth century. However, isolated outbreaks have occurred in recent years. Here we
investigate whether a lack of resistance in modern European varieties, increased presence of its
alternate host barberry and changes in climatic conditions could be facilitating its resurgence.
We report the first wheat stem rust occurrence in the United Kingdom in nearly 60 years,
with only 20% of UK wheat varieties resistant to this strain. Climate changes over the past 25
years also suggest increasingly conducive conditions for infection. Furthermore, we document
the first occurrence in decades of P. graminis on barberry in the UK . Our data illustrate that
wheat stem rust does occur in the UK and, when climatic conditions are conducive, could
severely harm wheat and barley production. |
