Method synopsis

Controlled feeding experiment providing different protein levels of horse feed to different matrilines while maintaining reference populations. Tests effects of food quality and quantity on juvenile growth and survival.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — The effect of food supplementation on juvenile growth and survival in Marmota flaviventris (2003), Journal of Mammalogy. Implementations in other papers (listed below) may differ.

1. Provide supplemental feed to treatment groups
   Supplemented 1 matriline with either high-protein horse feed (Omolene 300) or low-protein horse feed (Omolene 100, Purina Mills, LLC, St. Louis, Missouri) at each site. Reference populations were monitored for comparison. The only exception occurred during 1996 when the matriline that was supplemented at River was the only group to produce young.
   Quantities: 1 matriline per treatment type per site (high-protein, low-protein, reference)Duration: Summers of 1996-2000, during active seasonConditions: Supplemental food provided throughout active season
   Equipment: Omolene 300 horse feed, Omolene 100 horse feed

Typical Equipment

• Omolene 300 horse feed
• Omolene 100 horse feed

Output Measurements

• growth rate differences
• survival differences
• body mass at weaning
