Assessing the effects of farrowing crate design and mothering phenotype on pre-weaning piglet survival and performance using imaging technologies

Actual piglet mortality is a combination of a set of complex interactions between sow, piglet, environmental, and management factors. While crushing by the sow may be the ultimate cause of piglet mortality, there are many factors influencing the outcome, including hypothermia, starvation, and others. This study’s goals were to create a better environment for the piglets and the sow and to work towards methods of selecting sows with better mothering ability.

Improving feed efficiency of growing to finishing pigs fed high DDGS containing diet with different branched-chain amino acids to lysine ratio
Corn distillers dried grains with solubles (cDDGS) can replace portions of corn and soybean meal (SBM) in swine diets. However, high dietary inclusions of cDDGS can reduce growth performance, which...

An Integrated Approach to Improve While Herd Pig Survivability
Pre-weaning survival in US herds ranges from 80-90% with the majority of the death loss occurring in the first three days after birth from crushing from the dam. Risk factors for mortality are low...

Development of an Integrated Computerized Sensing System for Reproductive Management of the Swine Breeding Herd
Modern breeding farms rely on consistent flow of pigs through the production system. Reduced fertility can seriously disrupt animal production, flow and profit. These problems can originate from an...

Quantifying the Presence of Viral Material in Feed Delivered in Iowa
Despite evaluating a feed sample for 14 feed mills for 16 weeks, there was no detection of PRRSV, PEDV, PDCoV, and TGEV in any of the 224 collected feed samples. These results do not disprove that...
