Reproduction in gilts inseminated with PCV2-spiked semen. Protection by gilt vaccination with a sow PCV2 vaccine
PCV2 vaccination of the gilts prior to insemination with PCV2 spiked-semen showed a clear decrease of viral load in the gilts as well as a much lower viral excretion that were compatible with foetus protection.
Use of the production planning chart to schedule the sow replacements
The goal of this trick is to create a register of the coming into heat of the gilts that can be interpreted quickly and easily, and to control the day of the beginning of the treatment with altrenogest when we wish to delay their mating/service.
Simplified freezing of boar semen: possible?
Novel cryopreservation methods and containers are designed to increase semen cryosurvival without disturbing production of conventional liquid semen doses. This provides opportunities for gene banking and preserved fertility when inseminated deep intra uterine, alongside undisturbed commercial AI-dose production.
Coloured pegs for the identification of the number of returns to oestrus of the sows
The goal is to identify the number of returns to oestrus of the sows quickly and at a glance using coloured pegs.
Using ear tags for controlling heats in the quarantine area
A very simple system for monitoring the heats of replacement gilts that consists of putting them ear tags at each of the two heats during the quarantine period.
AI with thick rubber bands
The goal is to inseminate quickly the sows after the first stimulus by the boar, but keeping the stimulation.
Ireland: PRRS outbreak
Danish pig meat exports declined during 2012
Nature is wise: Optimum moment for the mating
The author considers which is the ideal day for the mating and sets out the improvements in the results obtained when weaning on Monday.
Thompson's tip: Boar stimulation
Clinical case: Reproductive failure
There was an increase of repetitions in females (at 17-28 days, cyclic and acyclic, with a repeat rate of 22%) and mucous-like, white to brown (chocolate) vulvovaginal discharge hours after artificial insemination.
