Managing Winter Ventilation

One small difference when it comes to winter ventilation, is that for a period of time, in late fall and also in early spring, staff need to be more vigilant on a day to day basis to ensure room temperature fluctuations are kept to a minimum. This usually means daily vigilance monitoring first and second stage ventilation fans and either installing or

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

Evaluation of Temperature Conditions in Trucks During Transport of Market Pigs to Slaughter in Four Seasons

Author(s): Harold Gonyou, Jen Brown, T. S. Samarakone, T. Crowe, S. Torrey, R. Bergeron, T. Widowski, C. Dewey, and L. Faucitano Publication Date: October 5, 2011 Reference: Centred on Swine 17-1 Country: Canada   Summary: Previous research at PSC has shown there is significant variation in conditions (temperature and humidity) among different compartments in trucks

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

Genesus Global Technical Report, Adding Customer Value with Genotype Information

Nick Boddicker, PhD, Genesus Inc. Genesus has written a number of articles on the importance of genomic information to improve genetic gain. That is because genomic information can greatly improve the accuracy of estimated breeding values (EBVs), particularly for lowly heritable traits (total number born), traits that can only be collected on the carcass (pH,

Response of Growing-Finishing Pigs to Dietary Energy Concentration

Author(s): J. F. Patience, A. D. Beaulieu and R.T. Zijlstra Publication Date: January 1, 2004 Reference: Centred on Swine Volume 10, Number 3, Winter 2004 Country: Canada   Summary: The primary objective of pork production is to produce lean meat in a cost effective and sustainable manner. From a nutritional perspective, energy is perhaps the

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 ( . There will be different opinions on the value of these proposed changes, especially as it

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.

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

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
