Genesus Global Technical Report, Whole Carcass Pork Quality

Whole Carcass Pork Quality Bob Kemp, VP Genetic Programs and R&D, Genesus Inc   As most industry participants know, the USDA Agricultural Marketing Service is seeking comment on the proposed changes to the standards of pork carcass grades (https://www.federalregister.gov/documents/2017/10/23/2017-22934/united-states-standards-for-grades-of-pork-carcasses) . There will be different opinions on the value of these proposed changes, especially as it

Adequate gilt acclimation helps minimize the PRRSV ‘tax’

As seen in PigHealthtoday.com By Clayton Johnson, DVM Carthage Veterinary Service Integrated Veterinary Network   Despite decades of intense research and tremendous deployment of resources, porcine reproductive and respiratory syndrome (PRRS) remains the most costly production disease among swine industries throughout the world. Although some progress has been made, it’s estimated that PRRS still costs

Space and Water Availability Issues for Nursery and Grow-Finish Pigs

Author(s): Dr. Mike Brumm Publication Date: January 1, 2006 Reference: Proceedings of the 2006 Manitoba Swine Seminar Country: Canada   Summary: Economic success of a modern facility relies largely on the methods of providing feed and water as well as how many pigs are in the facility. Maximum stocking density space is determined by how

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,

Reducing Aggression in Sows at Mixing: Does Floor Space Matter?

When sows are mixed in large groups there can be a significant amount of aggression between sows as social hierarchies are established. This aggression can lead to traumatic injuries and consequently there are welfare and economic concerns. For many years, some producers have intuitively been providing additional floor space for sows when they are mixed.

Genesus Global Technical Report, Minding Your Gilts’ Prenatal Environment

Minding Your Gilts’ Prenatal Environment Pius B. Mwansa, PhD   The lifelong performance of pigs is known to be affected by conditions during gestation (uterine) and early life (neonatal, 21 days after birth). Adverse conditions and stressors during gestation or nursing can have a negative impact on a gilts performance during their lifetime and can

Investigating ventilation system requirements for a sow gestation barn converted to group housing

Computer simulation was utilized to assess the performance of different ventilation system configurations needed for a sow gestation barn newly-converted to group housing. Various configurations of the ventilation system involving varying capacities and locations of exhaust fans as well as size, design and location of air inlets, were examined based on indoor air quality (i.e.,

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

The Impact of Piglet Birth Weight on Subsequent Growout Performance and Carcass Quality

Author(s): J.F. Patience, A.D. Beaulieu and T. Osmanagic Publication Date: January 1, 2006 Reference: Prairie Swine Centre Annual Research Report 2006 Country: Canada   Summary: SUMMARY Increased litter size resulted in decreased average birth weight, but how no effect on body weight variability at birth or later in life. Carcass quality was unaffected by litter
