Accomplishments
Short-term Outcomes:
Across objectives, we have evaluated nutritional and feeding strategies in sows to improve reproductive performance and efficiency with the goal of improving economic outcomes and sustainability. Data are currently being evaluated to determine impacts on sow productivity, health, and piglet viability.
Outputs:
Tsung Tsai, Gary A Apgar, Mark J Estienne, Mark Wilson, Charles V Maxwell. 2020. A cooperative study assessing reproductive performance in sows fed diets supplemented with organic or inorganic sources of trace minerals. Trans. Anim. Sci. 4:59-66. https://doi.org/10.1093/tas/txz178.
Activities:
1) Boron
The objective of this study is to determine the effect of boron supplementation on the reproductive performance of sows. Boron will be supplemented as sodium borate pentahydrate to sows at 0, 5, and 25 ppm. Boron treatments will be provided continuously during both gestation and lactation for two parities. Currently, the University of Kentucky has completed 3 continuous parities on this project and has collected data on sow and piglet performance and bone characteristics. The Kentucky station will proceed and summarize the data and work on publishing a manuscript.
2) Phase Feeding
The objective of this project is to determine the impact of feeding during late gestation of sows on productivity and longevity. South Dakota State University has worked on this project and feeding trials have been completed. The subsequent approach will shift more towards a modeling approach with the intent to focus on basic trials. It appears that bump feeding may not be a good strategy unless energy can be diluted. Feeding trials will be summarized and
Milestones:
Committee members actively participated in sow research projects and results and outcomes will be developed by the current committee with the goal of communicating beneficial impacts through active engagement with scientists, producers and industry personnel.
Impacts
- Key nutritional strategies are being developed to improve productivity in sows which will increase profitability and decrease resources used for every pound of pig produced., leading to improved sustainability
