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.
Gestating sows in group
Do the accommodation conditions for your gestating sows in group comply with the welfare normatives? Find out with the new test on welfare.
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.

Hypor is pleased to announce the acquisition of Designed Genetics. Designed Genetics, based in Lockport, Manitoba (Canada), is widely recognized as a leader in Duroc breeding, with a growing share of the Duroc boar market globally.
JSR to build New Nucleus in China
JSR Genetics, the UK-based international pig breeding company, has agreed a joint venture to build and stock a state of the art Nucleus on a Greenfield site in China. The 900 sow Nucleus will be located in the Hubei province of China and is expected to be complete in December 2010. The deal, which includes the shipment of both dam lines and sire lines, reinforces JSR’s commitment to investing in Nucleus facilities within the target market.
JSR: Lifetime sow performance - a key indicator of profit
Pigs per sow per year and numbers weaned have always been the main performance criteria adopted by pig producers to judge the success of their business. Both are useful indicators, indeed JSR have a commercial target of 25 pigs per sow per year, but it is important that producers keep an open mind on how they can measure unit efficiency and productivity.
ACMC: Still potential to boost sow output
Rapid progress in sow productivity in commercial pig herds is still possible, according to Yorkshire-based pig-breeding company ACMC.
Benefits of synchronizing ovulation with porcine luteinizing hormone in a fixed-time insemination protocol in weaned multiparous sows
Double insemination of multiparous sows, timed to coincide with optimal sow fertility, may improve litter size.
Organization of the replacements II
In previous chapters we have looked at the importance of maintaining the ideal parity profile within each batch.
