White cows
were grouped into four treatments
groups according to the analogue principle (n
=
4
×
5). Lactating dairy cows were included in the
trial in the initial lactation phase with the average milk yield of 23.00
kg
per
day, fat content
4.10% and 3.20% protein content in milk.
The analyses of the chemical composition of legume
grains
show, that
crude protein and undegraded intake protein (UIP) were higher in fodder beans
than in peas, respectively 29.97% and 25.04% of dry
matter but UIP content, respectively 40.51%
and 39.69% of crude protein.
There was a total of 17 amino acids detected in legume grains and
soybean meal. The highest concentration of arginine, leucine, glutamic acid, aspartic acid and
isoleucine was in fod
der beans,
respectively 0.76%, 0.58%, 0.67%, 0.42% and 0.29% more than
in peas.
Even though the daily milk yields decreased for all the cow groups during the experiment,
which was normal during the lactation period, yet the milk yield decreases for the tri
al groups.
The highest total amount of amino acids in milk was detected in 3
rd
and 2
nd
trial cow groups,
respectively, 4.00
g

and 3.90

which was fed fodder beans and peas.
The milk sale and
feed cost summary records for the trial that lasted 90
days show that economic efficency of peas
plus beans has been positive.
