Identification of quantitative trait loci affecting female reproductive traits in a multigeneration Meishan-White composite swine population.
A multigeneration crossbred Meishan-White composite resource population was used to identify quantitative trait loci (QTL) for age at first estrus (AP) and the components of litter size: ovulationExpand

Early uterine development in pigs.
The capacity of pig uterine tissues to recognize and respond to maternal and conceptus signals determines whether pregnancy can be established and defines the environment in which embryonic and fetalExpand

MicroRNA expression profile in bovine cumulus-oocyte complexes: possible role of let-7 and miR-106a in the development of bovine oocytes.
The objectives of this study included: (1) identify the expression of miRNAs specific to bovine cumulus-oocyte complexes (COCs) during late oogenesis, (2) characterize the expression of candidateExpand

Differences in placental structure during gestation associated with large and small pig fetuses.
The efficiency of nutrient transport from the pregnant female pig to the developing fetus depends on the size and function of the placenta. It has been reported that maternal and fetal blood vesselsExpand

Conceptus, progesterone, and breed effects on uterine protein secretion in swine.
This experiment consisted of the following treatment-breed groups: 1) White crossbred gilts, 2) White crossbred gilts treated with progesterone (200 mg/d in corn oil given on d 2 and 3 after estrus),Expand

A simple novel measure of passive transfer of maternal immunoglobulin is predictive of preweaning mortality in piglets.
Two factors that contribute to preweaning mortality in piglets are the initiation of lactation by sows and their ability to nurse their piglets. The objective of this study was to determine if theExpand

Global characterization of porcine intrauterine proteins during early pregnancy.
Total protein secreted in the intrauterine lumen increases between day 10 and 13 post-estrus in both cyclic and pregnant gilts. The objective of this experiment was to identify those intrauterineExpand

Allelic variation in the erythropoietin receptor gene is associated with uterine capacity and litter size in swine.
A single nucleotide polymorphism (SNP; C vs. T) that creates an extra GATA-1 site (T allele) in intron 4 of the swine erythropoietin receptor (EPOR) gene was discovered and a genotyping assay forExpand

Molecular cloning and characterisation of heparanase mRNA in the porcine placenta throughout gestation.
Heparanase (HPSE) is an endoglycosidase that specifically degrades heparan sulfate, which is an abundant glycosaminoglycan of the pig placenta. The aim of the present study was to clone cDNA encodingExpand

Genomewide association and identification of candidate genes for ovulation rate in swine.
Reproductive efficiency has a great impact on the economic success of pork production. Ovulation rate is an early component of reproduction efficiency and contributes to the number of pigs born in aExpand
