Genesus Global Technical Report, The Broken Sow, December 14th 2015

  The Broken Sow Lorne and Vicki Tannas Lorne and Vick Tannas are swine specialists and nucleus support for Genesus farms in China. Stop looking at the dead piglet in the farrowing pen.  By the time you have found it you have missed out on the basic cause of its death.  Generally the cause has

Genesus Global Technical Report, Litter size and survival of piglets, November 2nd 2015

Dinesh Thekkoot, PhD. Over the past few decades, genetic selection for prolificacy in pigs has resulted in significant improvement in litter size at birth and at weaning. As this is a key way to improve overall efficiency of the production system, this trait is likely to continue as an important goal trait in most of

Swine Feed Efficiency: Impact of Feeder Design and Management

Introduction One of the factors that influence feed efficiency is how pigs access feed via the feeder. Feeder design primarily impacts feed efficiency by affecting the pigs’ access to feed and feed wastage. Gonyou and Lou (1997) tested 12 feeders and found that all 12 feeders had wastage of less than 5%; smaller pigs wasted

Jim Long Pork Commentary, USDA Red Meat & Poultry, October 19th 2015

Jim Long, President and CEO Genesus Genetics The October USDA projection for US Red Meat & Poultry Production for 2016 indicates expectations for major protein availability. Red Meat & Poultry Production Million Pounds We don’t need a computer, or need to be an ag–economist to figure that if USDA is correct that in 2016 we

Understanding Nutrient Utilization in Swine

o understand the science of swine nutrition, it is first necessary to understand how major nutritional components are utilized by swine to meet their nutrient needs. Proteins, carbohydrates, fats, vitamins, minerals, and water comprise the major nutritional components required by swine to meet maintenance, growth, and reproduction needs. Water is often an overlooked nutrient, and

Selection for residual feed intake alters the mitochondria protein profile in pigs.

Abstract Residual feed intake (RFI) is a production efficiency measurement used to account for the growth performance of an individual animal. Less efficient animals have greater levels of oxidative stress. A major source of in vivo oxidative stress is the mitochondria. In this study the protein profile of mitochondria was investigated to determine differences between
