Effects of low-dose naltrexone on feed intake, growth, endocrine and immune parameters in the recently-weaned pig
Masters Thesis, University of Tennessee, Knoxville
This study demonstrated that pre-weaning treatment with low-dose naltrexone can result in increased weight gain and modulation of the commonly-observed immune and stress responses to weaning. The possibility that a low-dose pre-weaning naltrexone regimen could cause increased post-weaning feed efficiency through modulating behaviors should be examined further. The use of low-dose naltrexone in commercial swine production may represent a means to manifest the positive changes associated with opioid treatments without the negative aspects of narcotic regulation and potential for human abuse.
