A farm apprentice could face jail for hitting, throwing and stamping on newborn calves.
Owen Nichol, 19, was filmed attacking the young cows and their mothers at Pyrland Farm in Taunton, Somerset, in December last year.
The abuse was captured on a covert camera placed in a barn by the charity Animal Equality.
During a four-minute clip, Nichol is seen kicking and punching a cow that had just given birth, as well as slamming a gate on it.
He is seen throwing one calf away from its mother and kicking and stamping on a calf seven times.
Nichol, of Taunton, is due to be sentenced at Taunton Magistrates' Court on Wednesday after admitting two charges of causing unnecessary suffering to animals at an earlier hearing.
Chair of the bench Jeff Collingwood previously said it was the worst case of animal abuse he had seen in his 23 years as a magistrate and warned Nichol he may face jail.
