Function and Benefits regarding MSP[RS] Resistant Starch

MSP® Resistant Starch Advertorial The swine industry continues to look at and evaluate alternative ways to control and manage the microbial ecosystem to insure a sustainable, environmentally friendly approach to pork production. A most promising method is the modulation of the gut microflora in pigs including, but certainly not limited to selected bacteria to inoculate

Genesus Global Technical Report, Strategies to maximize long-term genetic gain in the genomic era

  Dinesh Thekkoot PhD Genomic selection (GS) is a new method for improving economic traits in animal populations by utilizing information from molecular markers, phenotypes and pedigree. This method provides the opportunity to estimate the breeding values of selection candidates more accurately and much earlier in life and for traits that are difficult to measure

Efficiency of Energy Utilization by Growing Pigs

Feeding pigs specific diets based on potential growth rate as determined by growth rate in the nursery may decrease variability in grow-out and finishing. In our study, however, pigs separated into slow, average or fast potential growth rates by determining growth rate in the nursery had comparable growth rates, feed intake and rates of protein

Duration of Senecavirus A Shedding From Clinically Affected and Non-affected Sows and Piglets After a Breeding Herd Infection

Project Title and SHIC Project Identification Number: Duration of Senecavirus A shedding from clinically affected and non -affected sows and piglets after a breeding herd infection. (SHIC Project # 15 -206) Principal Investigation: Dr. Chris Rademacher (cjrdvm@iastate.edu; 515-294-8792) Institution: Iowa State University Industry Summary: This study was designed to evaluate the length of shedding of

Genesus Global Technical Report, Big Data

By Nick Boddicker, Ph.D. Geneticist   Data collection and interpretation is a critical part to a swine genetics breeding program. Without data and its interpretation, genetic progress cannot be made. As technology evolves the ability to collect new data emerges, and a successful breeding company will capitalize on these new technologies. Furthermore, as technology evolves,

Optimizing Dietary Energy for Maximum Profitability in Growing-Finishing Pigs

The swine nutrition teams at Kansas State University (KSU) and Pig Improvement Company (PIC) have developed a tool to optimize the level of dietary net energy for growing-finishing pigs to maximize profitability. Feed represents approximately 70-80% of the cost of a grow-finishing pig and about half of that cost is related to energy. Feeding the

Lessons learned from PRRS outbreak investigations

As seen in PigHealthtoday.com By Derald Holtkamp, MS, DVM Iowa State University, College of Veterinary MedicineAmes, Iowa It’s been three decades since veterinarians and researchers first recognized porcine reproductive and respiratory syndrome (PRRS).1 Despite years of research and experience, the disease still causes productivity losses in the US worth $664 million annually.2   Arguably, the

Why PRRS elimination doesn’t work in some herds, By Amber Stricker, DVM Suidae Health and Production Algona, Iowa

By Amber Stricker, DVM Suidae Health and Production Algona, Iowa As seen in PigHealthtoday.com Over the years, there’s been considerable progress in the development of strategies aimed at eliminating porcine respiratory and reproductive syndrome virus (PRRSV). I define successful PRRSV elimination as the absence of clinical disease in the breeding herd and, more importantly, the

Manipulation and regulation of post-weaning growth in the pig

Read the complete article The objective of this dissertation was to investigate the manipulation and regulation of post-weaning growth in the pig. Specific objectives, as reflected in the individual chapters of this thesis, were to investigate the basis for differences in post-weaning growth rate and the modification of growth achieved through the use of two

Identification, treatment and prevention of shoulder lesions in sows

Shoulder lesions are most commonly observed in sows during the weeks following farrowing. Long periods of lying combined with poor body condition can increase the likelihood of sows developing shoulder sores. The prevalence of shoulder lesions varies greatly depending on farm and sow factors, with anywhere from 10 to 50% of sows being affected. Shoulder
