Abstract
Intoduction. The Lotus uliginosuscv Maku legume
is a forage plant with a good productive behavior.
It is known because of its protein contribution and
its content of condfensedtannins, which can improve
the use of the protein in the intestine. Objetive. To
determine the post-ruminaldigestability of the Lotus
uliginosuscv Maku´s protein that can not be degraded in rumen (DPPNDR) by the use of the mobile
nylon bag technique with no pre-digestion in pigs.
Materials and methods. Three Holstein cows,
each one with a ruminal cannula, were used, and
so were three 35 kg pigs in their growth stage. The
animals were kept in corrals and/or independent
cages. Three regrowth ages were used, and they
conformed the treatmentes T1:15, T2:30 and T3:45
reghrowth days, respectively. The data of raw protein disappearance in cows and pigs were analyzed by the use of a random blocks statistic design.
Results. For the ruminal degradability variable and
the total raw protein digestability, the highest value
obtained was that of T1 (57,24 and 73,99 %, respectively). Nevertheless, no differences were observed
in the not degradable in rumenraw protein between
treatments (P>0.05). Discussion. The total quantity of raw protein degraded in T1 could be caused
by the effect of the low fiber and tannins quantity in
such a legume. Conclusion. TheLotus uliginosuscv
Makuharvested after 15 days of regrowth is a good
alternative to feed dairy cows in high tropic production systems in Colombia
