Measuring Time-to-Virus-Negative-Piglets Interval in PRRSv Positive Sow Herds
The point at which a PRRSV-positive breeding herd begins to consistently produce entire groups of PRRSV-negative weaned pigs is important. First, PRRSV-negative weaned pigs can begin to co-mingle. Second, PRRSV-negative weaned pigs can sig­nal when it...
Feed Processing and Nutritional Quality among Wheat Classes Fed to Weaned Pigs
Feed processing and nutritional quality for CPS and Durum wheats have traditionally been expected to be lower than for Hard Red Spring (HRS). ...
Ceva Valora® as an Efficient Alternative to Surgical Castration
Male pigs are castrated in order to limit or eliminate problematic aggressive behavior, uncontrolled mating and a boar taint, which represents a significant food quality problem, write I. Kiss, V. Palya, R. Krejci and P. Mazerolles, Ceva....
How Do We Effectively Re-invest in our Swine Operations?
Nationally we have an aging ‘fleet’ of barns, with the last big building effort concentrated between 1991 and 1998; these barns have seen more than half their productive life, even with good maintenance. ...
What’s Wrong with My Pigs? - Rectal Prolapse
Rectal prolapse can look quite ordinary but can have a serious impact on animal health. It can prevent removal of metabolites produced during the digestive process, cause pain, encourage biting by pen-mates – thus leading to infection and even bacteraemia...
Syringeability of Hyogen®, a Vaccine Against Mycoplasma hyopneumoniae
Pneumonia induced by M. hyopneumoniae is considered one of the most wide spread and most important chronic diseases in pigs, write P. Forget, S. Lacoste, S. Gobbi, P. Mazerolles, R. Krejci and A. Lopez, Ceva....
Efficiency of Energy Utilization by Growing Pigs Selected for Potential Growth Rate
The normal variability in growth rate that exists within a group of pigs causes inefficiencies in nutrient utilization and contributes to variation in carcass composition....
Comparison of Time to PRRSv-Stability and Production Losses
To control PRRSv, herd closure (pig introduction into breeding herds is interrupted to allow the pathogen to die out) combined with whole-herd exposure to a live PRRSv (modified-live virus, MLV vaccine, or live-resident herd virus, LVI) is a commonly...
Maximizing Crossbred Pig Performance
Crossbreeding is the most widely used production system in the swine industry, and thus the genetic improvement goal is to improve crossbred performance under commercial conditions, writes Dinesh Thekkoot PhD, Genesus Inc. ...
What’s Wrong With My Pigs? Ear Necrosis
Porcine ear necrosis syndrome (PENS) in pigs has been reported as an increasing health problem in many countries with intensive pig farming. PENS exhibits as tissue damage to the tips of ears. Researchers have found it occasionally in pigs at three...
Effect of Modified-Live PRRS Virus Vaccine on Shedding of Wild-Type Virus from Pigs
A clear way to reduce the risk of infection (or reinfection) of a farm by PRRSv is to reduce the presence of virus in the environment. This study was designed to determine if the use of a PRRS modified-live virus vaccine (MLV) reduced the viral shedding...
Animal Variation and the Derivation of Optimal Shipping Strategies for Finishing Pigs
The difference between the average individual and the population mean response depends on the amount of genetic variation in a herd....
The Hidden Dangers of Lipopolysaccharides
Lipopolysaccharides pose a serious and often overlooked risk to pigs. Several tips can help limit their negative impacts, writes Diego Padoan DVM, BIOMIN Swine Technical Sales Manager EMA....
Management Factors Associated with Sow Farrowing Rate
The objectives of this study were to determine associations between low farrowing rate and various management factors in sow herds. ...
Risk Factors for Prolapses in Sows
In animal production, an abdominal organ prolapse is a condition where an internal organ moves from its normal position in the abdominal cavity to the exterior through the anus or vulva....
The Importance of Liver Protection for Sows
A sow’s liver is commonly under stress. A number of actions can help protect the liver and support healthy animals, write André Van Lankveld, Swine Technical Manager and Karin Nährer, Mycotoxin Risk Management Product Manager....
Stochastic Model of PRRS Control Strategies on a US Swine Farm
This article looks at the effectiveness of different combinations of control strategies for PRRS at the individual herd level. The goal is to determine the most effective strategy for PRRS virus control...
Creep Feeding in the Farrowing Room: Do the Outcomes Depend on Weaning Age?
Creep feed could benefit older weaned piglets by supplementing nutrients in sows’ milk. Additionally, it could aid the transition to solid feed at weaning, perhaps more of a benefit to the younger weaned piglet. ...
Tryptophan:Lysine Ratio Requirement for Nursery and Finishing Pigs
Tryptophan (Trp) is an essential amino acid that has a large impact on feed intake regulation by manipulation of metabolic pathways. ...
Managing Energy Intake and Costs of Grow-Finish Pigs
The cost of feed has been rising and while research has focused on amino acid requirements and cost, research on the cost of energy itself has been behind. ...
Economic Model for Optimum Tryptophan:Lysine Ratio for Nursery and Finishing Pigs
This tool, developed by Kansas State University and Ajinomoto Heartland, calculates the most economical Standardized Ileal Digestible (SID) Tryptophan (Trp) to Lysine (Lys) ratio by taking into account information specific to your production system and...
What’s Wrong With My Pigs? - Vomiting
Vomiting should not be confused with regurgitation...
Managing Variation to Achieve Uniformity in Pig Production
Many packers utilize payment methods that require producers to ship pigs that meet certain targets in order to maximize income from their pigs. These targets are largely centered around slaughter weight and lean yield. If a pigs weight is too light it...
