Post-insemination level of feeding does not influence embryonic survival and growth in highly prolific gilts
This study was designed to investigate the influence of a high level of feeding during early gestation on embryonic survival and variability of embryonic development in hyperprolific LW gilts.
Dietary protein intake and stage of lactation differentially modulate amino acid transporter mRNA abundance in porcine mammary tissue
Mammary gene expression of AA transporter is not affected by dietary protein intake.
TOPIGS Philippines starts InGene partnership with biggest pig producer
TOPIGS Philippines and Monterey Foods Corporation (MFC), the biggest pig operation in the Philippines, have formally signed an InGene partnership agreement. Now TOPIGS can start to supply pig genetics to Monterey, starting in their South Mindanao Live Operations.
Denmark - The Minister of Agriculture studies proposals to diminish the piglet mortality rate
In Denmark, several studies about piglet mortality puts the rate at 24% during the first 4 weeks of life. These results have been deemed “unacceptable” by the Danish Minister of Agriculture, Henrik Hoegh.
AgFeed Industries, Inc. Announces Stocking Agreement for Xinyu Production Pod
AgFeed Industries, Inc., one of the largest independent hog production and animal nutrient companies in China, today announced an agreement on terms for the stocking of the first phase of the Xinyu production pod starting in the fourth quarter of 2010 with PIC (Pig Improvement Company), a division of Genus PLC.
Proportion of the litter farrowed, litter size, and progesterone and estradiol effects on piglet birth intervals and stillbirths
Stillbirth in swine ranges from 2 to 9%, resulting in a significant loss of piglets. Previous studies clearly indicate a relationship between prolonged birth intervals and stillbirth, but factors influencing birth intervals are not fully known. To characterize birth intervals and stillbirth, farrowing was recorded during three farrowing seasons.
Thawing boar semen in the presence of seminal plasma: Effects on sperm quality and fertility
The present studies confirm an adverse effect of inseminating FT sperm on sperm quality and sow fertility but suggest that thawing FT sperm in 50% SP may partially alleviate these adverse effects.
Environmental and sow-related factors affecting the duration of farrowing
Allowing the sow to move freely before farrowing, reducing the constipation state and avoid excessive fattening during late pregnancy all appear to be key factors in shortening farrowing time and reducing perinatal mortality.
Organization of the replacements III
In the previous chapter we began to describe several systems for recording clearly and quickly the dates that gilts come into heat and for planning gilt service.

Parent-of-origin effects cause genetic variation in pig performance traits
In order to assess the relative importance of genomic imprinting for the genetic variation of traits economically relevant for pork production, a data set containing 21 209 records from Large White pigs was analysed.
IPIC - Advanced Reproductive Management Seminars
Pork producers are invited to attend either of two workshops focusing on advanced swine reproductive management topics scheduled for early next month in northwest Iowa and northeast Nebraska.
