A question of feed conversion
Pig farmers need to know whether boars have been individually tested for feed conversion and whether they have an EBV (Estimated Breeding Value) for this trait

Genetic resistance to PRRS
There is sufficient genetic variation in host response to infection to allow future breeding goals for enhanced resistance or tolerance so that there are grounds to believe that it may be possible to breed commercial animals that have increased genetic resistance or tolerance to the disease.

Dietary supplementation with 0.8% L-Arginine between days 0 and 25 of gestation reduces litter size in gilt
Dietary L-Arginine supplementation may negatively affect gilt reproductive performance.
Organization of replacements V
On many farms the introduction of gilts is not homogenous. However, the introduction of a similar number of gilts to each productive batch would be ideal. How can we do this?
Farrowing Room
Are the measures taken with the pig in the farrowing room correct? Are the facilities optimal?
Breakthrough in livestock sex selection
Ovasort Limited, which is based in Cardiff, has discovered sex-linked proteins on the surface of sperm cells of both pigs and cattle, and has developed a prototype product to identify and separate the male and female cells for each sex in both species.
Farrowing programming II
The gestation period in the majority of sows is usually around 113 to 115 days. However, a percentage of sows can farrow normally up to 3 days before or after.

United Kingdom - Scottish pig industry unveils new eahlth project
The Scottish pig industry and Quality Meat Scotland are taking action to promote high health status in the national pig herd and avoid thousands of pounds of losses through disease introduction.
Intra-uterine insemination with low numbers of frozen–thawed boar spermatozoa in spontaneous and induced ovulating sows under field conditions
The present study was conducted to evaluate non-return rate (NR), farrowing rate (FR), and number of total pigs born/litter (TB) of weaned sows after intra-uterine insemination (IUI) using low numbers of frozen–thawed (FT) spermatozoa.
Longitudinal field study to assess sow level risk factors associated with stillborn piglets
The aim of this study was to identify risk factors for stillborn piglets at sow level in commercial pig herds in northern Belgium. In total, 545 sows of 22 pig herds were included in the study. Stillborn piglets were observed in 48.3% of the litters and the mean stillbirth rate of the sows was 7.5%.
