Effectiveness of different farrowing induction protocols in sows using alphaprostol on day 114 of gestation
The aim of this study was to investigate the effects of different induction protocols when applied on d114 of gestation.
Genomic analysis reveals selection for Asian genes in European pigs following human-mediated introgression
Researchers from Wageningen University explain that a number of important characteristics of European pigs have Asian origins.
Measures of the ovaries and uterus during development of gilts selected for differences in uterine capacity
Selection for increased UC results in larger ovaries and uterine horns, but TRU was not useful for estimating these traits in gilts of the age studied.
Compounds from multilayer plastic bags cause reproductive failures in artificial insemination
This is the first described relationship between reproductive failure and toxic compounds released from plastic bags.
The battle of the sexes starts in the oviduct: modulation of oviductal transcriptome by X and Y-bearing spermatozoa
Data suggest that the oviduct functions as a biological sensor that screens the spermatozoon, and then responds by modifying the oviductal environment.

In ..Effect of immunological stress to neuroendocrine and gene expression in different swine breeds
This study concluded that Laiwu had stronger capacity of immunological stress resistance and next was Lulai among three breeds. Chromium yeast helped piglets relieve immunological stress.
Supplementing cryopreservation media with reduced glutathione increases fertility of sows
Supplementing freezing media with 2 mm GSH greatly improves boar sperm cryopreservation technology, as it significantly improves the fertilizing ability of frozen-thawed spermatozoa.
Establishment of the 2012 vitamin D requirements in swine
Dietary treatments of ≥800 IU/kg feed showed beneficial effects for breeding swine in terms of bone mineral content and ultimate strength, decreased number of still born piglets, and greater vitamin D status in comparison with dietary treatments of 200 IU/kg of feed.
Role of interleukin-1β in the regulation of porcine corpora lutea during the late luteal phase of the cycle and during pregnancy
In this study, the influence of IL-1β on secretory activity within the corpora lutea (CL) of cyclic and gravid pigs was determined in vitro during different stages of the CL lifespan.
