Is it doable to breed higher moms at no cost farrowing circumstances? Jenelle Dunkelberger, international well being and conduct platform lead for Topigs Norsvin, says the worldwide development to discover different housing methods for pig manufacturing prompted her firm to search for options.
“Conduct is a good instance of a trait that we’re nonetheless studying the right way to outline,” Dunkelberger mentioned throughout a seminar on the American Affiliation of Swine Veterinarians annual assembly on March 2. “For instance, how do you outline good maternal conduct? What sort of conduct are you actually searching for?”
Using digicam expertise and sensors may help generate information that can be utilized to check traits like conduct, amongst different issues, she factors out. However researchers nonetheless must have a way of what to search for that’s indicative of excellent conduct.
“What we do know is {that a} good mom ought to verify her environment and train care when mendacity or altering positions,” she says. “But it surely goes a lot deeper than that. For instance, pigs are good, and we don’t but absolutely perceive how sows talk with their piglets.”
Pork producers need to understand how vital these complicated traits will likely be in the way forward for pig manufacturing, particularly now that the trade has entry to instruments that may seize information which has by no means been captured earlier than.
What’s Greatest for the Sow and Her Piglets?
“For some, eradicating farrowing crates is believed to translate to raised sow welfare,” she says. “However in fact, the explanation we’ve got farrowing crates within the first place is to guard the welfare of the piglets. Subsequently, if farrowing crates are eliminated, novel administration methods will likely be required to make sure that we defend the welfare of the piglets. Now we have to maximise each sow and piglet welfare.”
Outcomes from our analysis trial confirmed that piglet crushing was 8% increased for the free farrowing versus crated group, Dunkelberger says.
This highlights the necessity to develop methods to mitigate piglet losses in such housing methods. Because of this, one other goal of this analysis was to analyze the potential of genetic choice for enhanced mothering capacity as a possible resolution to this challenge.
Topigs Norsvin has been deciding on for enhanced mothering capacity as a part of its breeding program for over 20 years. Dunkelberger says they do that by gathering information in a crated setting as a result of that’s been the construction of the trade. Knowledge is collected in that setting and used to calculate a sow’s genetic benefit for mothering capacity.
“We calculate breeding values for mothering capacity because the maternal impact on piglet survival. In different phrases, the affect of the mom’s genes on the power to maintain her piglets alive,” she says.
Within the examine that Dunkelberger referenced, Topigs Norsvin needed to guage whether or not genetic choice for improved maternal conduct validates in a free farrowing setting. Massive White x Landrace sows have been group-housed throughout gestation and transported to the farrowing unit at roughly 109 days of gestation. Within the farrowing unit, half of the sows have been assigned to the free farrowing group, and the remaining half to the crated group, the place parity construction was balanced throughout teams. Sows and piglets have been monitored all through the length of the examine utilizing cameras mounted above every pen or crate.
General piglet mortality was considerably increased within the free farrowing group (14.2%) versus 5.9% within the crated group. In line with this discovering, mortality attributable to crushing was additionally considerably increased at no cost farrowing (11.8%) versus crated litters (1.1%).
“The vast majority of piglet loss of life loss was attributable to crushing,” she says. “However while you have a look at the impact of breeding worth for mothering capacity, we noticed that sows with a greater breeding worth for mothering capacity had decrease total piglet mortality, together with decrease mortality attributable to crushing. We noticed this consequence no matter housing sort (crated or free farrowing setting).”
The takeaway is that genetic choice for higher mothering capacity validates in a crated setting, but additionally in a free farrowing setting, Dunkelberger factors out.
“We’re inspired by this discovering,” she says. “Outcomes from this examine present that our present strategy of breeding for enhanced mothering capacity reduces piglet losses in a crated setting, but additionally in a free farrowing setting. Because of this genetic choice for higher maternal conduct will be a part of a technique to scale back piglet loss of life loss, if and the place these different housing methods are getting used.”
