Lalu Prasad was sent to Birsa Munda Central Jail.
BJP latched on to conviction of RJD chief Lalu Prasad in a fodder scam case on Saturday to target Congress, alleging that UPA has been an "alliance of corruption" while Bihar deputy chief minister Sushil Kumar Modi said the former CM had "reaped what he sowed".
The quantum of punishment will be pronounced by the court on January 3.
Corruption allegations related to a fodder scam, which continued for several years from even prior to Lalu's term as chief minister in 1990, were levelled against him in 1998 when he stepped down as chief minister and installed his wife as his successor.
It is a case pertaining to fraudulent withdrawal of more than 89 lakh from Deoghar treasury between 1991 and 1994.
Both are accused in four fodder scam cases.

The steps are the latest from the International Olympic Committee in a growing list of sanctions against Russian athletes who competed in Sochi.
The scene, however, took a drastic turn around 4:30 pm when the court announced its verdict holding Yadav guilty as charged while exonerating Mishra in the case.
Overall, more than Rs 900 crore was reportedly siphoned off from the Chaibasa treasury for two decades.
"Whatever has happened to Lalu Prasad is an outcome of rajneetik dwesh (political ill will)". When he was convicted in 2013 in case RC 20-A/96, he was MP from Saran in Bihar.
In a series of tweets on his way to jail, Lalu sought to portray his conviction as the result of social clashes between the upper and lower classes and castes."Powerful people and powerful classes always managed to divide society into the ruling and the ruled classes". "The RJD will challenge the CBI court's order in the HC soon", senior party leader Jagdanand Singh, considered close to Lalu, told the media.
In Patna, the Rashtriya Janata Dal said it will challenge the verdict in the High Court. Jagannath Mishra, who was accompanied by his son and JD (U) leader Nitish Mishra, expressed gratitude to the judiciary for his acquittal, saying he had "absolutely no role" in the scam.
