The breeding and feeding of self produced
pulses to livestock is one of the important
directions of research for reducing the production costs of livestock products. Experiment on the
effective using of the field beans to lambs for fattening was arranged in three replications using
the Latvian Da
rk
-
headed breed male lambs. The mixture of concentrated feed consisted of 50%
of bean and 50% of oat. Lambs were weighed at the starting and ending of the trial. Carcass
quality was assessed according to the European standard for the classification of carc
asses of
sheep.
The fattening period lasted from 37 to 94 days, on average 63
±
3.6 days. The average live
weight gain per day was 247.4
±
13.85
g, and live weight increased on average by 15.3
±
0.94
kg.
Significantly higher (
P
<
0.05) growth rate during fattening period reached lambs of 3rd group,
where lambs started fattening above 27
kg of live weight, reaching a 276.8
±
26.26
g daily live
weight gain.
The quality of the obtained carcasses was an average, and score for musculatu
re was
from R to O class, but the average score for fat deposition was from 3 to 4 points. The mixture of
field beans and oats provided 19.3% of crude protein and 12.1
MJ of metabolizable energy per
1kg of dry matter, and its unlimited feeding provided med
ium lamb's growth rate. The level of
feed conversion was
7.56
kg of dry matter
