Effects of castration and immunization against GnRH on the immune system and the adrenocortical axis in pigs
This study aimed at understanding the effects of testicular hormones on immunity and stress reactivity in pigs.
Clinical case: Unexpected findings block semen exports
The semen was destined for Japan which requires the donor boar to be tested with negative results within 60 days prior to collection for export for: Vesicular Stomatitis, Aujesky’s disease, PRRS, Brucellosis, Leptospirosis, and Tuberculosis.
Easily fermentable carbohydrates reduce skatole formation in the distal intestine of entire male pigs
Chicory inulin and raw potato starch as ingredients to reduce the boar taint of meat from intact male pigs.
Tracking the effect of chicory on boar taint
The discovery of how chicory affects boar taint can, in the long run, open the door to a more targeted and efficient way of preventing boar taint via the feed.
EFSA - Preparatory work for the future assessing of pig's welfare (I)
Preparatory work for the future development of animal based measures for assessing the welfare of sow, boar and piglet including aspects related to pig castration.
JSR Breeding Pigs Fly Into China
Over eight-hundred high health, genetically advanced breeding pigs have successfully touched down in China this week. The animals were transported from the UK onboard a specially chartered 747 aircraft on behalf of JSR Genetics.
Mating guidelines (III)
In the last chapter we examined mating guidelines that came rather close to being ideal, given that they achieve the following objectives: At least one mating should be adjusted to meet the ideal time and achieve the first objective with the least number of matings.
USA - The US and Ukraine sign health protocol for swine semen
The bilateral health veterinary certificate for swine semen was finalized on January 6th, 2011. US swine genetics industry may proceed with shipments to Ukraine.
Russia - Temporary restrictions on import of breeding animals from a number of Danish farms
In 2010 the Rosselkhoznadzor authorized import of 1360 breeding pigs from Denmark to the Belgorodskaya Oblast. The animals were imported in three consignments accompanied with phytosanitary certificates issued by the National Veterinary Service of Denmark according to which the animals were clinically healthy. 320 animals with lesions on legs and limp were detected in the course of the daily clinical examination in the quarantine period.
Effect of storage for 24 h at 18°C on sperm quality and a comparison of two assays for sperm membrane lipid peroxidation
Boars having normal (71.1 ± 1.2%; n = 10) or low (35.12 ± 3.9%; n = 10) sperm motility 24 h after collection were used, and semen was evaluated following storage in Beltsville Thawing Solution (BTS) for 24 h at 18°C. Sperm lipids were extracted and lipid peroxidation quantified.
United Kingdom signs deal to export breeding pigs to China
Business Secretary Vince Cable today signed an agreement worth many millions of pounds for the UK economy that will allow the export of British breeding pigs to China, home to half of the world’s pig population.
Agreement has also been reached on health certification to allow a start to be made on the export of UK pigmeat to China.
Capacitation status of stored boar spermatozoa is related to litter size of sows
Capacitation status as measured by CTC staining is a useful predictor of sperm fertility, equivalent to SPA. Moreover, original capacitation status exhibited better predictive ability for small litters than for large ones. Therefore, subfertile boars can be identified primarily by capacitation status
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
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.
