Using first and second parity number born alive information to estimate later reproductive performance in sows

Early parity number born alive classification effectively predicts later parity performance. Sows classified as high in both parity one and in parity two had larger litters in later parities.

NPD: An invisible component for herd productivity

We recommend that producers pay more attention to gilts and sows that are at risk of increasing NPD. Situations of increased risk are described.

Perinatal dietary choline deficiency in sows

Dietary choline deficiency induces alterations in plasma choline metabolites which are evident at the end of lactation. Betaine and select FAs in milk are sensitive to maternal dietary choline deficiency and day of lactation. Alterations in concentrations of these nutrients may affect early-life neonatal development.

"Ghost sows" and the other 8 most frequent errors when processing data (1/2)

This first part deals with backward and impossible data, i.e. the sows that are no longer in the farm but still appear both in the management softwatre and the 100% delivery rates in gilts.

Relationships between ovulation rate and embryonic and placental characteristics in multiparous sows at 35 days of pregnancy

A high avulation rate results in an moderate increase in the number of vital embryos at day 35 of pregnancy, but compromises development in the surviving embryonic/placental units, suggesting that the future growth and survival of the embryos might be further compromised.
