‘Heterosis’ in litter size of chimaeric mice
Genetical Research, 1985 SUMMARYAggregation chimaeras were made from embryos of C57BL/6 and BALB/c mice. Chimaeric and control females were mated with ICR males at 8 weeks of age and their litter sizes were evaluated over a 5-month period after the first mating. Progeny tests showed that 18 of 27 chimaeras produced oocytes of both genotypes.

Effects of the Litter of Origin and Rearing Litter Size on the Reproductive Potential of Replacement Gilts. [PDF]
Animals (Basel)This study aimed to assess how prenatal and early postnatal conditions affect the future reproductive performance of young female pigs (gilts). Female piglets were selected from sows in their 3rd and 4th parity. Vaginal and cervical length (VCL) was measured using a catheter during the first (VCLI) and second (VCLII) oestrus.

CHANGES IN UTERINE CAPABILITY DUE TO INCREASED LITTER SIZE AT 7 WEEKS OF PREGNANCY IN KACANG GOAT
Jurnal Kedokteran Hewan, 2018 The purpose of this research was to study the changes in uterine support capability power due to increase of litter size in Kacang goat. In this study, 9 pregnant female Kacang goats were divided into 4 different groups based on litter size, namely 1, 2,

Effect of does parity order on litter homogeneity parameters
Italian Journal of Animal Science, 2020 In rabbits’ reproductive performance, litter size, birth weight, growth, and mortality rate are among the most important indicators to define the productive potential and they are associated with parity order.

Effect of SNPs on Litter Size in Swine. [PDF]
Curr Issues Mol BiolAlthough sows do not directly enter the market, they play an important role in piglet breeding on farms. They consume large amounts of feed, resulting in a significant environmental burden. Pig farms can increase their income and reduce environmental pollution by increasing the litter size (LS) of swine.

The determinants of optimal litter size in free-ranging red squirrels [PDF]
, 2000 Food availability, energetic ceilings, and life-history trade-offs have been proposed as potential determinants of offspring number in many animals. We investigated the role of these factors in determining litter size in a free-ranging population of red ...

Advanced Science, EarlyView.FES‐derived MGE spheroids exhibit progenitor‐stage alterations in developmental trajectory and hypoxia‐responsive transcriptional programs, followed by functional disruption. Gestational hypoxia recapitulates impaired progenitor proliferation, shortened cell‐cycle progression, interneuron developmental abnormalities, and schizophrenia‐like behaviors in
