Interval from last insemination to culling: Culling reasons from practise and the correlation with longevity

This study showed the potential to select on longer interval from last insemination to culling in days and thereby select against sows to be culled within the reproduction, locomotion, accident, general disorder and peri-partum cull class and to be culled at the end of a parity.

Energy supplementation to neonatal piglets of low birth weight

Energy supplementation to neonatal piglets of low birth weight may reduce piglet mortality.

Pre-lactation nutrition strategies for optimal sow and piglet performance

The evolution of genetics in modern sows requires nutritionists to evolve their diets and feeding programs accordingly. Nutritionist need to consider not only the role of nutrition on metabolism but also on hormone regulation and subsequent reproduction.

Optimization of post-cervical insemination in pigs: critical points

This article lists the critical points that must be considered for a successful post-cervical insemination in sows.

The cortisol response to ACTH in pigs, heritability and influence of corticosteroid-binding globulin

The results are valuable for the genetic selection of animals to explore the consequences on production and robustness traits.

Iron deficiency and anemia in piglets and the effect of iron status at weaning on post-weaning performance

Consumption of nursery starter feeds containing high concentrations of ZnO is associated with post-weaning anemia.

Measures to reduce neonatal mortality: management, genetics and new housing for lactating sows

Neonatal mortality does not only depend on the design of the farrowing crate, but also on genetic and management factors, as well as litter size, especially with the increased use of hyper-prolific dam lines.

NutritionAbstract

Reference values for immunocrit ratios to assess maternal antibody uptake in 1-day-old piglets

The IR method ascertains whether piglets are receiving adequate maternal antibodies until their own immune systems are developed.

Facilities-Equipment Abstract

Effect of radiant heat at the birth site in farrowing crates on hypothermia and behaviour in neonatal piglets

Radiant heating behind the sows reduced hypothermia in new-born piglets and indicate that providing heat during the first half hour after birth is important.

Comparison of specimens for detection of PRRSv infection in boar studs

These results showed that the highest assurance of providing PRRSV-negative semen to sow farms should be based on rRT-PCR testing of serum collected at the time of semen collection.

Canada gains market access for live breeding cattle and swine to Georgia

Canadian cattle and swine breeders can immediately begin exporting to this market. Georgian breeders also benefit by gaining access to Canada’s world-class animal genetics.

Current state of post-cervical insemination in multiparous, primiparous and nulliparous sows

It is necessary to find alternatives to definitely implement this technique in primiparous sows and start its use in gilts.

ManagementAbstract

Analysis of hygienic critical control points in boar semen production

The present study emphasizes the need for both training of the laboratory staff in monitoring HCCP in routine semen production and audits in such AI centers for the external control of hygiene parameters.

The birthing process of a piglet

Scott Phillips, a pig farmer from Missouri, shows how he pays individual attention to the mother pigs as they give birth to their piglets.

Distinguishing sows with different genetics using cards and ear tags with different colours

Usual standard on many farms to identify a sow with different genetics quickly.

Genetics-ReproductionAbstract

Porcine semen as a vector for transmission of viral pathogens

Prevention of viral semen contamination should be the primary focus because it is easier to prevent contamination than to eliminate viruses once present in semen.
