Lamb’s birth weight and litter weight were found to be related to ewe weight. Deviations from generally applicable formulae indicated an interaction between the genotype of the lamb and the maternal environment, as suggested in egg transfer experim

Differences in ovarian follicular dynamics between ewe breeds and between lines within breeds were shown to result from a different follicle recruitment and selection process. Synchrony and asynchrony of embryos were shown to depend largely on lutein

After multiple egg transfer litter size (LS) in recipient ewes from some breeds was greater than their potential natural size; Finnish Landrace, not Booroola Merino recipients, tended to be superior to recipient ewes from other breeds with a lower na

Varying rates of partial fertilization (2–40%) were found in literature. These data gave evidence that the `all-or-none' hypothesis on fertilization is not correct, at least in a number of sheep breeds and experimental conditions. Furthermore, ther

Synopsis Chicks hatched from eggs incubated at two temperatures (36.8 °C, 37.8 °C) but similar humidities (30 mmHg during the first 18 d and 40 mmHg thereafter) were reared for 12 weeks in groups of six at 22 °C and in a relative humidity of 45 to
