Research Project: Evaluating the Effects Of Low Crude Protein Diets During Lactation on Metabolic Heat Production and Heat Stress Response of Sows

Location: Livestock Behavior Research

Project Number: 5020-32000-013-38-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Dec 1, 2017
End Date: Aug 14, 2018

Objective:
The objective of the experiment is to determine whether feeding a reduced crude protein diet with an optimum amino acid (AA) balance reduces stress and improves overall well-being in lactating sows exposed to high ambient temperatures.

Approach:
Lactating sows will be exposed to heat stress conditions and fed a diet containing an optimum balance of amino acid (AA) based on the National Research Council's 2012 but with lower levels of crude protein. We will then monitor thermal status, heat production, and performance throughout a 21 day lactation period to determine whether feeding low crude protein diets is an effective strategy to reduce stress during times of high heat loads.
