The quality of compound feeds used in livestock diets could be enhanced by means of
domestically produced pulses. Nevertheless, there are available few research studies that would
allow us to identify the economic efficiency of livestock diets with pulses and the digestibility of
protein by livestock for deer farming. Accordingly, the present research aims to identify the
economic efficiency of diets supplemented with domestically produced pulses - faba beans, peas
and lupine beans - for captive deer. The research conducted a feeding experiment on captive deer
(Cervus elaphus) kept in fenced areas to identify the economic efficiency of diets supplemented
with three legume species: peas (variety ‘Vitra’), faba beans (variety ‘Fuego’) and narrow-leaved
lupin seeds (variety ‘Boregine’). Deer productivity was assessed by live weight, live weight gain,
feed intake and protein efficiency ratio during the experimental period, as well as feed cost per
live weight gain unit. The research found that feeding deer diets containing peas, faba beans and
lupine beans as protein-rich feedstuffs was economically advantageous - at the same cost of feed,
deer productivity increased and per-unit production costs decreased. Live weight gains during the
experimental period were 1.02% higher in group 2 (pea diet), 1.78% higher in group 3 (faba bean
diet) and 2.91% higher in group 4 (lupine diet) than in the control group. During the experimental
period, the highest protein efficiency ratio was found in group 4 fed a diet containing lupine beans
- a unit of protein fed (1 kg) yielded the highest weight gain or 0.43 kg. Feed costs per kg of live
weight gain were the lowest in group 4 (2.32 EUR kg-1
), 2.48 EUR kg-1
in group 3 and
2.70 EUR kg-1
in group 2, which was 20.56%, 14.81% and 7.39%, respectively, lower than those
in the control group.
