Hormonal indexes as predictors of porcine reproductive traits

Animal Science Journal, 2023
AbstractThe aim of the present study was to examine the applicability of several hormonal indexes for early prediction of puberty and reproductive state in pigs. For this purpose, we have compared the level of hormones leptin, estradiol, progesterone, and IGF‐I in the blood of gilts at 150 days of age and their indexes of puberty and ovarian state at ...

Seeds of future past: climate change and the thermal memory of plant reproductive traits

Biological Reviews of The Cambridge Philosophical Society, 2018
Plant persistence and migration in face of climate change depends on successful reproduction by seed, a central aspect of plant life that drives population dynamics, community assembly and species distributions.

Maternal Traits and Reproduction in Richardson's Ground Squirrels

Ecology, 1995
Differences among conspecifics in body mass result from underlying differences in structural size and physiological condition. To determine whether the structural or physiological component of body mass has a stronger influence on reproductive traits at parturition, we studied the body composition (lean dry mass and fat content), structural size (1st ...

Women with sickle cell trait: Reproductive decision-making

Journal of Reproductive and Infant Psychology, 2003
There is no universal cure at present for sickle cell disease; therefore, the only way to lessen the risk of transmission is to make informed reproductive choices. The aim of this study was to explore reproductive decision-making in women who are 'healthy carriers' of sickle cell disease.

Genetic correlations for reproductive and growth traits in rabbits

Canadian Journal of Animal Science, 2019
: The objective of this study was to obtain heritability estimates for reproductive (litter size at birth, number born alive, litter size at weaning) and growth traits (individual weaning weight, individual weight at the end of the fattening period ...

Relationships among bovine male and female reproductive traits

Australian Veterinary Journal, 1990
SUMMARY No significant relationship (p>0.05) was found between age at puberty in heifers and the age and scrotal circumference at puberty in related bulls. There was a significant effect (p<0.0l) of genotype and sire on age at puberty of heifers and a significant effect (p<0.05) of genotype on weight at puberty in heifers.

Heterosis and recombination effects on pig reproductive traits

Journal of Animal Science, 2002
The objective was to estimate breed, heterosis, and recombination effects on pig reproductive traits in two different four-breed composite populations. Breeds included Yorkshire, Landrace, Large White, and Chester White in Exp. 1 and Duroc, Hampshire, Pietrain, and Spot in Exp. 2. Data were recorded on purebred pigs, two-breed cross pigs, and pigs from

Reproductive Traits of Trees in OFR

2002
When plants start to reproduce (when they reach a certain size or the age of onset of flowering and fruiting), how often and how many of the plants produce offspring during their lifetime (frequency of reproduction) and how many offspring are produced in a year (magnitude of reproduction) are important factors of plant demography, because these factors

Genomic prediction of reproduction traits for Merino sheep

Animal Genetics, 2017
SummaryEconomically important reproduction traits in sheep, such as number of lambs weaned and litter size, are expressed only in females and later in life after most selection decisions are made, which makes them ideal candidates for genomic selection.
