The authors find that the program substantially increases dairy and meat consumption among Rwandan households who were given a dairy cow or a meat goat, respectively. The study also found marginally statistically significant reductions in wasting (weight for height) and underweight (weight for age) in children of households that were recipients of meat goats, and reductions in stunting (height for age) among children in households that received dairy cows.
