The use of hyperprolific sow lines has increased litter size considerably in the last three
decades. Nowadays, in some countries litters can reach up to 18–20 piglets being a major …

Intrauterine growth restriction (IUGR) remains a major problem in swine production since the
associated low birth weight leads to high rates of pre‐weaning morbidity and mortality plus …

In Europe, in the last 3 decades, there has been a constant increase in litter size due to the
use of superior maternal line genetics. Those sows giving birth to more piglets than their …

Embryo mortality is responsible for greater losses in litter size in pigs. It is well known that
pregnancy establishment is a complex process, and important changes occur continuously …

Background In polytocous livestock species, litter size and offspring weight act
antagonistically; in modern pig breeds, selection for increased litter size has resulted in …

The exacerbation of the greenhouse effect has made heat stress (HS) an important risk
factor for the occurrence of intrauterine growth restriction (IUGR). The experiment aims to …

Background Oxidative stress in placenta is associated with the occurrence of adverse
pregnancy outcomes in sow, but there are few satisfactory treatment strategies for these …

ABSTRACT A suboptimal early nutritional environment (ie, excess of energy, sugar, and fat
intake) can increase susceptibility to diseases and neurocognitive disorders. The purpose of …

It is known that pig offspring born from pregnant pigs exposed to elevated ambient
temperatures during gestation have altered phenotypes, possibly due to placental …

The fetal fluids and uterine flushings of pigs contain higher concentrations of fructose than
glucose, but fructose is not detected in maternal blood. Fructose can be synthesized from …
