A key recommendation from the gilt development strategy for the University of Alberta's Swine Research and Technology Centre was to breed gilts at 135 to 150 kg (298 to 331 lb) to reach at least 175 kg (386 lb) after farrowing.
Heavier gilts, is there a benefit? Sows usually mobilize tissue and lose some weight in lactation. But if too much weight is lost, performance will...

Research conducted by the University of Manitoba indicates, from an animal welfare perspective, sows housed in groups on straw tend to out perform those housed in conventional slatted floor systems.
Research at the University of Manitoba's National Centre for Livestock and the Environment is comparing sows housed in conventional slated floor facilities to those housed in groups on straw.
The two groups use the same genetics and are managed similarly.

In general, as total litter size has increased, there has been a tendency for an increase in the percentage of piglets born dead. It is now quite common to see an average stillbirth rate of 1.0 piglets per litter, or even more, in data from individual farms and herd recording schemes. This presents an opportunity to improve Weaning Capacity by reducing the level of stillbirths through a sound genetic program and good management procedures. The Hypor genetic program includes selection for...

An exciting and growing body of scientific evidence supports the notion that the maternal environment in which fetuses develop plays a profound role in the development of the reproductive and other physiologic systems. Fetal programming refers to the process by which an acute or chronic stimulus in utero (i.e., in the uterus) establishes a permanent response in the fetus that impacts physiologic function later in life. The concept of fetal programming in swine is illustrated by an...

A total of 239 sows (PIC C-22) were used in this experiment. Sows were randomly allotted to one of the two experimental treatments approximately 5 days before their expected farrowing date. Control sows did not receive any topdress; sows on the WEANMOR+® treatment received a single daily topdress of 25 g of WEANMOR+®. Topdressing the sow feed with WEANMOR+® reduced (P 0.67)....

Scientists aim to reduce piglet mortality by developing a new type of climate control and monitoring in farrowing pens. The result could be improved pig welfare and farmer finances. For a newborn piglet, slipping from a warm and secure environment inside its mother’s womb and landing on a cool floor in a modern farrowing pen is not much fun. It is a rather tepid start in life for a piglet that in its first few days of life is very poor at regulating body temperature. Figures from sow...

Individual housing of pregnant females is a common practice in the swine industry. Barnett et al. (2001) estimated that at least 60 to 70% of U.S. sows are housed in stalls throughout gestation. The use of gestation stalls is currently one of the most contentious welfare issues facing pork producers. Typical gestation stalls are approximately 2' wide and 7' long and physically limit sows to standing, sitting, and lying. This severe restriction of freedom of movement has been robustly...

Planned farrowing is a highly effective method of improving breeding and production flow on the pig unit. The key to any successful breeding unit is to firstly produce the greatest number of pigs born alive and then keep them alive until sale. Having the ability to predict and control farrowing routines will help achieve this.
The use of planned farrowing medication - with prostaglandins such as Planate - can be used as a tool to allow ‘batch management’ of sows and gilts. Prostaglandins...

A Farrowing Caretaker Interest Group formed in January and February will help people who work in the farrowing area of any pork producing operation improve skills critical for farrowing success.
The interest group lets caretakers learn at a time and location convenient to them, said Duane Reese, University of Nebraska swine specialist, who will lead the group along with Locke Karriker of the College of Veterinary Medicine at Iowa State. It is sponsored by Cooperative Extension at the...

A “largely integrated” North American hog industry had the U.S. importing about 8 percent of the hogs it slaughtered in 2004 from Canada.
Imports of about 8 million Canadian hogs this past year represent an eightfold increase from just 15 years ago, according to an analysis by Mildred Haley, an agricultural economist with USDA.
Ron Plain, a University of Missouri livestock economist, agreed that relatively open borders gave Canadian and U.S. hog firms the expectation “that hogs and pork...

An Illinois Farrowing Conference has been scheduled for Wednesday, Dec. 8 at the University of Illinois Extension Building on the Illinois State Fairgrounds in Springfield. This program will focus on the delivery of information to help people improve the performance of sows and piglets in the farrowing barn according to Rob Knox, U of I Extension swine reproductive specialist.
The program features Duane Reese, a leading expert in farrowing swine and Swine Extension Specialist from the...

More and more British pig farms are changing over to batch farrowing.
Whilst this may have great health benefits, it also places far greater pressure on resources. Where there may have been one week's worth of pigs demanding more of a particular resource, now there are five.
With some resources, this may be beneficial in various ways. For example, some producers find that concentrating on a particular activity once every five weeks, instead of all activities each week, aids teamwork and...

For the second consecutive quarter Wisconsin's hog inventory on September 1 totaled 440,000 head. Compared to last year, overall hog numbers are down 60,000 head. Market hogs, at 390,000 head, and breeding hogs, at 50,000 head, did not fluctuate when compared to June. Both decreased from September 1, 2003.
The state's June - August 2004 quarter pig crop amounted to 212,000 head, down 15 percent from the previous year and 7 percent less than the previous quarter. Sows farrowing during the...
