Thompson's tip: Boar stimulation
For optimum results, producers should organise their work so that once stimulated by the boar all the stimulated sows can be served within a 20-minute period.
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.
Advances in AI - the future
Already delivering the ‘best of the best’ genetics and farrowing rates of up to 95%, the role of AI in pig production is assured. But what of the future?
Thompson's tip: AI - take care of semen in cold weather
A weak area on many pig farms, particularly in cold weather, can be where all the doses needed for the morning’s services are taken out and left by the pen.
Effect of site of sperm deposition on fertility when sows are inseminated with aged semen
In the present study, intrauterine deposition of sperm did allow maintenance of farrowing rate, but did not ameliorate the adverse effect of inseminating aged sperm on litter size.
Stimulation during insemination: The Danish perspective
In Denmark the most common practice is to always stimulate with the boar together with a complete 5 point pattern of stimulation carried out by the inseminator.
Managing a 3-week batch system, weaning at the beginning of the week
This may be a good option when farrowings and litter control during the first days are the priority.
Managing a 3-week batch system
On small farms it is better to group tasks on specific days, leaving other days with less tasks in order to organize days off...
Task organization: What day of the week should we wean? Several weanings per week
On large farms, it is common to wean more than once per week. This way, tasks can be homogenized throughout the week: each day will have a similar volume of work as the previous day.
Productivity fillip for Maltese pig industry
A switch of genetics and a new approach to health and management has revitalised pig production on the tiny Mediterranean island of Malta.
What day of the week should we wean?
A large part of the work on a swine farm can be divided into 3 key tasks: weaning, mating and farrowing. The day chosen for weaning determines the other two tasks; first, the matings, and then, as a consequence, the farrowings (the 2 ‘great events’ of which productivity of a farm depends on).
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.
