Canada: Government helps swine producers boost exports
Investment of more than $1.3 million to help the Canadian Swine Exporters Association (CSEA) increase its international marketing and promotion of Canadian purebred swine genetics.

How do we level litters after delivery?
In the previous chapter we discussed the ideal time to level out litters of newborn piglets. Here's how to do it.
Effects of castration and immunization against GnRH on the immune system and the adrenocortical axis in pigs
This study aimed at understanding the effects of testicular hormones on immunity and stress reactivity in pigs.
Denmark: alternatives for reducing piglets mortality rate
The report “Piglet mortality in Denmark” published in 2010 described a number of alternatives for reducing the mortality rate. These various alternatives are also mentioned in a new report published in January 2012.
From the Wallingford Pig Study Group to PIC
In 1955, a group in the United Kingdom called the Wallingford Pig Study Group was concerned that the traditional purebred breeders were not producing the right pig for future markets.
TOPIGS Philippines imports top genetics for San Miguel Foods, Inc.
TOPIGS Philippines recently imported 1111 top SPF genetics from Canada to set up a new nucleus farm for San Miguel Foods, Inc. in the Isabela province of the country.
Varying creep feed duration affects pre-weaning and post-weaning performance and behavior of piglet and sow
Creep feed initiated from day 5 and 10 reduce diarrhea scores in piglets and the estrus interval in sows.
The dilemma of fostering on the first day of life
The ingestion of Ig in sufficient quantity is the first priority. So much so that it even comes before the factor that seems most important: the feed supply.
Weaning on Friday and using altrenogest to avoid weekend farrowings; is it possible?
What if we were to wean on Friday and were able to block farrowings for 2 days? The bulk of farrowings would be concentrated on Monday.
Testing females to improve accuracy
With high-priced feed accounting for the major cost of production, it is important to test the females in all lines, as well as the males, since they contribute 50 per cent of the genetics to the next generation.
Monitoring of Farrowing (III): Factors that increase stillbirths
Long farrowings increase mortality, and deaths occur above all in the last 1/3 of the delivery.
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.
Clinical case: Abortion in young sows
Abortion occurred in 90% of first parity sows and in 10% of second parity sows.
Management of farrowing objectives to achieve optimal piglet weight at weaning (II): batches every two weeks
The dispersion of matings described in the previous article is even more drastic on farms operating in bands over one week.
TOPIGS research: SNPs for more uniform and bigger litters found
TOPIGS researchers have found a series of SNPs that define a genetic region which explains genetic variation for litter size and uniformity between litters.
Stillbirth and preweaning mortality in litters of sows induced to farrow with supervision
To evaluate the benefits of induced farrowing with supervision on rates of stillbirths and preweaning mortality,a total of 159 multiparous sows were assigned in approximately equal numbers to two groups.
