the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

15 صفحه اولThe effects of oviposition time on egg weight loss during storage and incubation, fertility, and hatchability of broiler hatching eggs.
An experiment was conducted to determine the effect of time of oviposition, generally representing different positions in the normal egg laying sequence, on egg weight loss during storage and incubation, and on fertility and fertile hatchability of eggs from mid-lay (42 wk) and old (67 wk) broiler breeders. A total of 1,800 eggs (900 eggs per flock age) were collected during 10 consecutive days...
متن کاملEffects of relative humidity during incubation on hatchability and body weight of broiler chicks from young breeder flocks.
We conducted an experiment to determine the effect of relative humidity (RH) during incubation on characteristics of hatched chicks from eggs produced by young broiler breeders. Eggs were collected for 6 consecutive d, every other week, in each of two trials from broiler breeder flocks at 26, 28, and 30 wk of age. The eggs were randomly distributed in machines according to RH treatments that we...
متن کاملBroiler incubation. 1. Effect of elevated temperature during late incubation on body weight and organs of chicks.
Three experiments were conducted to investigate the effect of increased egg temperature during the final third of incubation on BW, yolk sac, heart, and digestive organs of broiler chicks at hatching. Egg temperatures were found to be approximately 1.0 to 1.5 degrees C higher than incubator air temperature. Elevated egg temperature (39.5 degrees C) after embryonic day 14 generally accelerated h...
