Litter-of-origin trait effects on gilt development
Colostrum consumption, birth weights, preweaning growth rate, number weaned, and parity are associated with gilt development traits during later life.

Daily feeding regimen affects the pig growth and behaviour
Restricted feeding may improve lean percentage in growing pigs without a negative impact in welfare.
"Ghost sows" and the other 8 most frequent errors when processing data (1/2)
This first part deals with backward and impossible data, i.e. the sows that are no longer in the farm but still appear both in the management softwatre and the 100% delivery rates in gilts.
Relationships between ovulation rate and embryonic and placental characteristics in multiparous sows at 35 days of pregnancy
A high avulation rate results in an moderate increase in the number of vital embryos at day 35 of pregnancy, but compromises development in the surviving embryonic/placental units, suggesting that the future growth and survival of the embryos might be further compromised.
Health protocols for replacements: gastrointestinal diseases (3/3)
Exposure during acclimatization can be considered the first dose of a vaccine, and pre-farrowing exposure its booster.
Requirements of essential fatty acids for lactating sows
Dietary essential fatty acid supplementation in sow during lactation affects further reproductive performance.
Use of altrenogest on pig farm
The shorter and lower dose regime saves money but there is an increased risk of follicular cyst development, which may occur at doses below 13mg/day.
Impact of maternal vitamin D supplementation on sows and litter
Maternal vitamin D3 supplementation improves serum concentration in both sows and piglets but, does not affect their performance.
Management interventions for large litters: Economic assessment
Milk supplementation shows much higher growth rates in the fattening stage, so its implementation would be interesting to regain body condition in animals with low birth weight.
Effects of zearalenone-diet in ovaries of post-weaning piglets
Zearalenone could promote the autocrine action or expression of the ghrelin gene in piglet ovary, and further accelerate the development of ovaries (follicles).
Observations of sows and piglets housed in farrowing pens with temporary crating or farrowing crates on a commercial farm
The current study demonstrated that the farrowing system design can influence sow behaviour, with pens allowing for more interactions between sows and their piglets.
How the anti-inflammatory drugs given to sows affect the piglets
Assessment of a study, by Enric de Marco, on the use of anti-inflammatory drugs in sows at farrowing in order to reduce piglet mortality and increase the weight of piglets at weaning.
Essential fatty acid supplementation during lactation is required to maximize the subsequent reproductive performance of the modern sow
A minimum dietary intake of both α-linolenic and linoleic acid is required for the modern lactating sow to achieve a maximum reproductive outcome.
Implementation of a peripartum feed
The handling disadvantages derived from the addition of an extra feed are outweighed by the improvement in production and decrease in the number of farrowing problems.
Coefficients of repeatability for colostrum and milk composition of PLW and PL sows over three consecutive lactations
It can be stated that the lactose content of sow colostrum in the first lactation could be indicative of a female's predisposition to produce colostrum and milk with similar lactose content over two consecutive lactations.
Lameness blindness (2/2)
The number of sows that suffer some kind of leg injury is much higher than is apparent, and even more so in second farrowings.
