Abstract :
Uterine involution and onset of estrus in PO
cows fed basal diets of rice straw and rice bran,
supplemented with lamtoro leaf meal are interesting
reproductive problems to study. Because what every
breeder wants is that after parturition occurs, their
livestock immediately experience uterine involution
followed by estrus so that mating can take place. To
address this problem, feed of a certain quality is very
necessary. On the other hand, agricultural waste products
such as rice straw and rice bran are widely available in
the community but have low nutritional content so
supplementation with lamtoro leaf meal would be an
alternative solution.
The research aims to study the process of uterine
involution and estrus onset of PO cows fed basal feed of
rice straw and rice bran, supplemented with lamtoro leaf
meal. A total of 10 PO cows aged around 4.5 years in late
pregnancy status were randomly grouped into two
treatments, namely the group that received basal feed of
rice straw and rice bran (R0) and the group that received
basal feed of rice straw and rice bran, supplemented with
lamtoro leaf meal ( R1). The research used experimental
methods and the results were analyzed using one-way
classification analysis of variance with the MINITAB 14
application. The results obtained showed that there was a
significant difference (P<0.05) in the variables of uterine
involution and estrus onset. Meanwhile, the symptoms of
estrus, conception rate and pregnancy index were not
significant (P>0.05). Dry matter consumption of feed was
not significant (P>0.05), but there were significant
differences in consumption of crude protein, TDN and
crude fiber in the two treatments (P>0.05). It was
concluded that supplementation of 50% lamtoro leaf flour
in basal feed of rice straw and rice bran was quite effective
in the occurrence of uterine involution and onset of estrus
in PO cows.
