Optimal timing of boar exposure relative to parturition for stimulation of lactation oestrus
This study evaluated the effect of full physical boar exposure at different stages of lactation on the incidence of lactation oestrus in both primiparous and multiparous sows.
The effect of numbers of frozen-thawed boar sperm and addition of prostaglandin F2α at insemination on fertility in pigs
These results indicate that AI using 2.0 × 109 FTS can result in acceptable pregnancy rates and litter sizes but with no measurable benefit for addition of prostaglandin.
Effect of sex of the pig on the sensory characteristics of the Biceps femoris and Semimembranosus muscles in dry‐cured hams
Organoleptic ham criteria for immunocastrated males hams were equivalent to those found for surgically castrated males and gilts hams, demonstrating the efficacy of vaccination in these study conditions.
Planning gilt service
The strategy involves synchronizing the gilts so they come into heat at the same time, in order to properly manage the number of inseminations targeted for each lot.
Colombia resumes the importation of live pigs from US and Canada
There were trade restrictions due to the presence of Porcine Epidemic Diarrhoea (PED) in both countries.
Effects of lactation length and boar contact in early lactation on expression of oestrus in multiparous sows
Boar contact is an effective method to stimulate oestrus within 26 days of farrowing in both lactating and weaned sows.
Use of paternity tests in swine
These tests have several practical applications, as the detection of boars that are linked to the appearance of hernias or the susceptibility towards certain enteric diseases or even syndromes like the PFTS.
Russia imposes temporary restrictions on import of pigs from the USA
Rosselkhoznadzor imposes temporary restrictions on import of breeding and commercial pigs as well as not-heat-treated blood products used for manufacturing feeds for food-producing animals from May 30, 2014.
Supplementing cryopreservation media with reduced glutathione increases fertility of sows
Supplementing freezing media with 2 mm GSH greatly improves boar sperm cryopreservation technology, as it significantly improves the fertilizing ability of frozen-thawed spermatozoa.

This agreement will strengthen the pig meat, fowl and wine exports.
Netherlands: significantly fewer pigs castrated over the past five years
Now nearly 75% of all boars in the Netherlands are not castrated.
