We review critical factors associated with reproductive performance of female breeding pigs,
their lifetime performance and herd productivity in commercial herds. The factors include …

Our objectives in this review are 1) to define the four components of sow lifetime
performance, 2) to organize the four components and other key measures in a lifetime …

The aim of the study was to identify the detailed impact of the season, parity and breed on
reproductive performance of sows. The experimental material consisted of 2100 sows, in 3 …

In modern swine production failure of sows to become pregnant within the expected time
after weaning results in major economic loss and culling of sows. The objective of this study …

Simple summary Progeny born to primiparous sows (gilt progeny) are born lighter, grow
slower, and have higher rates of mortality than piglets born to multiparous sows. An …

Background Sows' ability to produce an excessive amount of piglets has shaped modern
piglet production and there has been a steady increase in litter size during the last decades …

A research aimed at evaluating the reproductive performance of pigs as influenced by
breed, season, and parity was carried out. Reproductive performance records of 1383 sows …

In large organic litters, relationships between piglet birth weight, piglet uniformity and pre-
weaning piglet mortality were studied. Furthermore, effects of parity and insulin-stimulating …

Univariate or bivariate animal models were used to estimate the variance components and
co-variance components for eight reproductive traits: total number born (TNB), number born …

The present study investigated the influence of age at first estrus, body weight, and average
daily gain (ADG) of the replacement gilts on their subsequent reproductive performance as …
