Reproductive management: Puberty induction
Why induce puberty? If I do choose to induce puberty, what do I need to do, and when?
To induce or not to induce; has the answer changed?
Farrowing induction is needed to improve the ability of farm staff to supervise farrowing, but you need to be strategic; do not induce unless evidence says it is needed.
New vaginal drug delivery system to control time of farrowing and allow supervision of piglet delivery
Findings confirm the efficacy of the novel vaginal drug delivery system for induction of farrowing in sows.
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.
Obtaining colostrum from sows injected with long-acting oxytocin
Administer long-acting oxytocin to sows that have started farrowing to milk them more easily.
FDA highlights potential health risks to people exposed to altrenogest products for horses or pigs
The FDA is providing this alert because of the nature of the adverse events, some of which have occurred in teenage girls.
Combination of oviduct fluid and heparin to improve monospermic zygotes production during porcine in vitro fertilization
The present study was designed to evaluate the effect of porcine oocytes exposure to oviduct fluid before in vitro fertilization, during in vitro fertilization and during in vitro fertilization in combination with heparin.
The effects of male and female immunocastration on meat quality of pigs intended for dry-cured ham
It can be concluded that immunocastration could be interesting in pigs intended for dry-cured ham elaboration because in males improved the feed conversion ratio with no penalization of carcass or meat quality.
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.
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.
Data, hormones and holidays (2/2)
This article explains how the massive use of hormones helps synchronize heats and farrowings when workload scheduling, synchronization and production rates stability are priorities.
Data, hormones and holidays (1/2)
A strict schedule allows us to concentrate all the important events, and time periods where more attention/work is required, within the working days.
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.
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.
Genetic parameters for male fertility and its relationship to Skatole and Androstenone in Danish Landrace Boars
These data suggest that concentrations of skatole and androstenone can be reduced through genetic selection without negatively affecting important male fertility traits in Danish Landrace pigs.
