Reproductive performance of influenza A virus infected sows before and after vaccination
Vaccinating against the influenza A (H1N1)pdm09 virus, can improve reproductive performance in sow herds infected with pandemic influenza A virus.

Physiological stress biomarkers for prediction of pork quality variation
Lactate dehydrogenase could help predict pork quality variation, while cortisol, alanine amino transferase, and albumin could be useful in prediction of carcass quality.
Reproductive performance and expression of imprinted genes in somatic cell cloned boars
Cloned boars could be highly effective for proliferation of pigs with desirable characteristics, preservation of genetic resources and risk reduction against epidemic diseases.
Effect of boar seminal dose type: cervical compared with post-cervical insemination
Post-cervical artificial insemination doses took less time than cervical doses to reach the desired temperature, but sperm quality was similar for CAI- and PCAI-doses during storage.
Oral progesterone and caffeine in late gestation affects pigs
Caffeine supplementation of sows receiving progesterone to prevent premature farrowing impaired piglet survival during, and shortly after parturition.
Effect of suckling intensity of primiparous sows on production performance during current and subsequent parities
Increased suckling intensity increased litter weight gain but reduced piglet ADG. Following lactations were not negatively affected by increased suckling intensity of the first lactation. Loss of sow body reserves was reduced for the second lactation.

We’re excited to ..Antimicrobial capabilities of tea tree and rosemary essential oils on refrigerated swine seminal doses
Essential oils may act as antimicrobial agents in seminal doses serving as an alternative to traditional antimicrobials in the face of increasing antimicrobial resistance.
Analysis of steroids in gilt saliva to identify biomarkers of the period of receptivity
The objective of this study was to develop alternatives to hormonal treatments to synchronize oestrus of gilts.
Melatonin potentially acts directly on swine ovary
Melatonin interferes with cultured granulosa cell proliferation and steroidogenesis.
Caffeine administered to pregnant sows improves piglet vitality
Caffeine positively affected the vitality of the piglets, as indicated by greater vitality scores than that for the control group.
Altrenogest supplementation during early pregnancy improves swine embryonic development
There is a lack of information about progesterone supplementation during early pregnancy regarding swine embryonic development. The objective was to evaluate the effects of progesterone/progestin supplementation from Day 6 of pregnancy on swine reproductive parameters.
Post-thaw boar sperm motility is affected by prolonged storage of sperm in liquid nitrogen
The fact that the major phenotypic characteristic of boar spermatozoa, motility, is constrained by time of cryostorage should be considered when building cryobanks of pig semen.

Sperm DNA integrity in semen with good motility and morphology may be an additional prediction parameter for fertility in pigs.
A comparison between nulliparous and multiparous sows cervix with regard to post-cervical AI
The future design of AI strategies and catheters should take into consideration the morphological variations of the cervix lumen, which will depend on age and parity of the females.
Absence of seminal plasma from sperm-rich fraction decreases boar sperm quality characteristics
The seminal plasma from the sperm-rich fraction is important for the maintenance of adequate structural and functional characteristics of extended liquid boar semen.

AbstractA new device for deep cervical artificial insemination in gilts
The use of the deep cervical AI technique provides a new AI method as an alternative to cervical insemination and post-cervical artificial insemination for pigs.
Impact of light irradiation on preservation and function of mammalian spermatozoa
Mounting evidence indicates that light irradiation of mammalian spermatozoa (and of other animal species) increases their motility, capacitation and fertilizing ability, without causing any damage on the DNA.
Sperm membrane proteins associated with the boar semen cryopreservation
Boars sperm membrane proteins may explain differences in semen cryopreservation success, serving as freezability markers.
Effect of enriching the sow environment and diet during gestation on maternal stress and piglet survival
Enriching the sow environment and diet during gestation therefore improved sow welfare and reduced piglet mortality at and soon after birth.
Stillbirths in relation to sow hematological parameters at farrowing: A cohort study
Piglet stillbirth was associated with several hematological parameters of the sow, namely hemoglobin concentration, mean cell hemoglobin concentration...
Indirect genetic effects for growth rate in domestic pigs alter aggressive and manipulative biting behaviour
The results of this study show opportunities to reduce harmful biting behaviours in pigs.
The effect of age, interval collection and season on selected semen parameters and prediction of AI boars productivity
The possibility of planning the production level has a special importance for AI stations, and its inaccuracy should be minimized by eliminating the factors differentiating the quantity and quality of the ejaculate.
The genetic correlation between scapula shape and shoulder lesions in sows
It is expected to improve the genetic progress of shoulder lesions and body condition score.
Effects of the different levels of dietary vitamin D on boar performance and semen quality
The possible mechanism of vitamin D action on boar performance was explored.
