The non-legislative report by Polish MEP Janusz Wojciechowski "on the protection of animals during transport", technically classed as a "motion for a European Parliament Resolution", was fed through the Parliament's Agriculture and Rural Development Committee.
The report recommends the EU Commission enforces existing animal transport regulation of journey times, number of journeys, transport conditions, environmental and social costs of transport.
Although MEPs rejected an outright limit of eight-hour journey times for animals going to slaughter, they did recommend the EU Commission reconsider transport times overall.
The EC has said it does not intend to revisit animal transport legislation, choosing to reinforce implementation of the current rules.
Mr Smith, who voted against the report, said: "Scotland's farmers will be disappointed to hear that the attempt to put in place an eight-hour limit has still not been entirely killed off, although, to be honest, I don't expect the Commission to take much notice of such a weak demand hedged by caveats about the need to put science first. Commissioner Borg made it clear in the debate that eight hours is not on his agenda."
NFU Scotland's animal health and welfare policy manager, Penny Johnson, said: "Reassuringly, the EU Commission have previously noted they see no reason to look again at animal transport regulations and any welfare problems that arise from poor enforcement of the existing rules."
