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).

Economic impact of post-cervical insemination on a farm
Introduction of post-cervical insemination has a very significant economic impact on the whole of the pork industry, and is a challenge of parallel magnitude to that raised by the transition from natural service to artificial insemination.
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.
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.
Semen extenders on frozen-thawed boar sperm characteristics and distribution after deep intrauterine insemination in sows
We compared the effects of extenders of frozen-thawed semen on post-thaw sperm characteristics and the distribution of frozen-thawed spermatozoa in the female genital tract after fixed-timed deep intrauterine insemination (DIUI) in sows.
Health protocols for replacements: respiratory and systemic diseases (2/3)
We are talking about PRRSV, M. hyo, PCV2, App and swine influenza virus.
Effect of cross fostering on preweaning mortality
This study indicates that cross fostering was associated with lower risk for preweaning mortality.
Seasonal changes in concentration of steroid hormones in the spermatic cord vessels of the mature boar
There were greater steroid concentrations in arterial vessels during December in comparison to June.
Non-infectious causes of pre-weaning mortality in piglets
Piglet pre-weaning mortality (PWM) is one of the major reproductive components that affects herd productivity in the swine industry.
Assessment of the lactation feed intakes including environmental temperatures and betaine supplementation
Sow feed intake is limited at high temperature in ad libitum fed sows during lactation but, betaine supplemented sows may show higher feed intake during this period .
Genetic selection may be used to control pathogen susceptibility and the composition of the gut microbiota
Genetic selection provides a powerful tool to improve and maintain gut health in industrial pig production, and may in the future become a more sustainable alternative to the currently massive need for antibiotics.
New section on pig reproduction
In this new pig333's section, several international experts write articles on pig reproduction.
Low birth weight affects lifetime productive performance and longevity of female swine
The results of this study show that low BiW (<1 kg) negatively influences the production of piglets and longevity of female swine.
Control of oestrus in problem gilts and sows
Meeting batch breeding targets requires availability of enough service-ready weaned sows and gilts.
Do nurse sows and foster litters have impaired animal welfare?
The results show that nurse sows and their piglets to some extent experience more welfare problems than non-nurse sows with piglets at a similar age.
The effect of varying duration of water restriction on lactating sows
Duration of water restriction did not affect water consumption on a 24-h basis, nursing behaviour or performance.
