Feed supplemented strains have limited ability to compete with the indigenous intestinal microbiota of piglets.
CASTRUM study on alternative methods of anesthesia and analgesia for the castration of pigs
The CASTRUM study shows large differences in practice in European countries.
Paper in the farrowing quarters: not only for the piglets...
It is easy to see the reaction of the sows (of all of them!) when we supply them with paper. A handful in front of their snout or at the reach of their mouth is enough... oxytocin! It is like giving an injection!
Palygorskite dietary supplementation effects on back fat mobilization, leptin levels and oxidative stress in sows
The use of palygorskite in sow diets reduces oxidative stress in gestating sows.
Impact of maternally derived immunity on piglets’ immune response and protection against PCV2 after vaccination at different age
This study was aimed at evaluating the clinical protection, the level of Porcine circovirus type 2 (PCV2) viremia and the immune response (antibodies and IFN-γ secreting cells (SC)) in piglets derived from PCV2 vaccinated sows and themselves vaccinated against PCV2 at different age, namely at 4, 6 and 8 weeks.
Using first and second parity number born alive information to estimate later reproductive performance in sows
Early parity number born alive classification effectively predicts later parity performance. Sows classified as high in both parity one and in parity two had larger litters in later parities.
Optimization of post-cervical artificial insemination in gilts: Effect of cervical relaxation procedures and catheter type
Post-cervical (pC) artificial insemination (AI) has been successfully developed for application in multiparous sows, although it has proved problematic in gilts. This study analyzes the use of pC-AI in gilts by two experiments.
UK pig semen to improve pork quality in India
This latest move forms part of a large-scale development of the Punjabi pig sector and experts say it could open the door to other British suppliers.
