Here are three basic rules for deciding if and when to do cross fostering and use nurse sows.
Maternally derived immunity on immune responses elicited by piglet early vaccination: examples from respiratory and systemic pathogens
Depending on the levels of maternal derived immunity, a potential interference of vaccine intake may happen, jeopardizing vaccine seroconversion and efficacy.
Pulmonary lesions at the slaughterhouse: how to evaluate them
Collecting data at the slaughterhouse is a common method to obtain information on health and productive parameters, mainly from the last weeks of a pig’s life.
Mycoplasma hyopneumoniae vaccines
This article presents the main characteristics of the vaccines that can be found on the market.
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.
Impact of stress on immune function, health, and productivity (2/2)
We conclude this two-part series by Professor Pejsak by examining how immune stress affects the pig's body, gut, and production.
Impact of stress on immune function, health, and productivity (1/2)
What exactly goes on in a pig's body when exposed to acute or chronic stress? What implications does stress have on production? Professor Pejsak draws on decades of research to answer to explain.
Video: How to spot the signs of farrowing
Identifying the different stages of farrowing allows us to monitor the process and take measures to maximize the number of piglets born alive and their viability.
Answers about App pleuropneumonia (2/2): Diagnosis, monitoring, and eradication
In this second article Antonio Vela, Francisco José Pallarés, and David Espigares answer questions about the diagnosis, monitoring, and eradication of pleuropneumonia caused by Actinobacillus pleuropneumoniae (App).
Answers about pleuropneumonia caused by App (1/2): Evolution and control
We asked Antonio Vela, Francisco José Pallarés, and David Espigares about pleuropneumonia caused by Actinobacillus pleuropneumoniae (App). In this first article, we will talk about the evolution and control of the disease.
A 3-D approach to better understanding of swine flu: Direct control (3/3)
In this last article of the series, we discuss management strategies and the vaccines available to control swine influenza.
The Signs of farrowing: Physiology and sow behaviour
Understanding the farrowing process and recognizing the signs for the different stages of birth, help us to develop management plans to improve the likelihood for live born piglets.
Weaning without zinc oxide (3/3): The importance of environment, water, and other factors
This concludes our series of three articles with explanations from Alberto Garcia and Chretien Gielen about the measures to consider to reduce post-weaning diarrhea without the use of zinc oxide. We couldn't end without looking at key aspects such as the environment, water, and use of biologics.
A 3-D approach to better understanding of swine flu: The clinical picture (2/3)
The clinical picture associated with swine influenza is often complicated by temperature fluctuations, other viruses, or bacteria. In part two of this series, we look at the clinical signs of this disease.
Weaning without zinc oxide (2/3): Encouraging feed consumption after weaning
The ban on the use of zinc oxide starting June 2022 makes it necessary to review and improve many aspects of weaning, especially in its early stages. With Alberto García and Chretien Gielen we address key management points for successful weaning without the use of zinc oxide.
Weaning without zinc oxide (1/3): Good weaning starts in the farrowing room
We spoke with Alberto Garcia (Inga Food SA, Spain) and Chretien Gielen (De Varkenspraktijk, The Netherlands), to discuss aspects related to weaning management and conditions.
What fractions of the ejaculate should I include when preparing artificial insemination doses?
Currently, only the sperm-rich fraction is used. This article analyzes the possible use of the other fractions.
How does swine influenza virus facilitate secondary bacterial complications?
The influenza virus promotes colonization by secondary bacterial agents in the lung, facilitating their passage into the bloodstream.
Precision ultrasonography in sows: There’s much more than pregnancy check!
Here's how ultrasound can be used to visualize ovarian structures, assess the state of puberty, and diagnose ovarian pathologies.
Clinical case: Edema disease - The more I medicate, the more pigs die!
An outbreak of edema disease was treated with fasting and antibiotic therapy, but in subsequent batches these measures were no longer successful. The outbreak progresses and it was observed that when animals are medicated, either orally or parenterally, mortality increases both in number and speed.
Diarrhea in neonatal piglets: treatments
In a series of seven articles we have discussed with four prestigious veterinarians the different aspects of neonatal diarrhea: infection, nutrition, management, environment, etc. We couldn't end this series without specifically addressing how to manage treatment.
Diarrhea in neonatal piglets: management practices
Is it best to separate gilts from sows? Which biosecurity measures are most important? In this article, four renowned veterinarians discuss their recommendations.
Post-insemination management guidelines for swine
To conclude this series of articles, swine reproduction and artificial insemination specialist Javier Gil explains the importance of proper post-service management in terms of when to move sows and how to feed them.
