Can Maxammon Treated Cereals Improve DLWG?


Top Performing Beef Unit Improves with Maxammon

Glasgow Vet School conducted a Maxammon finishing trial on the farm of high performing beef specialists the Stewart family. They tested whether a new alternative treated grain source would outperform the existing system.

The Stewarts own a 600 acre farm, growing cereals and grass and currently have around 900 cattle. They operate a mixed herd, with the selection criteria based on growth potential and cattle that will utilise the system. Cattle are housed and finished mainly on grain, with those purchased in spring being turned out, then housed in July/August. They maximise what is grown on the farm and achieve good performance with home grown crimped cereals, with the ration also including pot ale and straw. They believe the higher proportion of grain being fed helps finish the cattle in a shorter time frame, compared to using more forage in the diet. With the availability of pot ale protein supply set to drop, they decided to look for an alternative diet - Maxammon treated barley with its higher protein content.

The Trial

The trial was designed and managed by Professor Nick Jonsson of Glasgow Vet School, in conjunction with Harbro. The new ration included Maxammon treated barley, molasses and a specifically designed mineral premix. This ration was fed to half of the cattle with the existing diet fed to the rest. The animals were allocated to groups based on equivalence of breed, age, body condition score and liveweight. All were subject to the same animal health management and were weighed at the beginning of the study, halfway through and at 90 days just prior to slaughter. They were observed fortnightly during the trial with measured variables including: indices of animal health (lameness, diarrhoea and pneumonia), daily liveweight gain, days required to finish cattle, proportion of animals meeting specifications, cost of ration and rumen analysis.

The cattle were weighed and sent to slaughter over a few weeks. Final recordings were taken and samples of the rumen studied, to analyse any contribution the ration had made. Professor Jonsson commented that the trial was the one of the best he had seen, not only for the way it was administered and managed on farm, including the collation analysis of the wealth of data, but also due to the sophistication of the Stewart’s handling and weighing facilities and the farm’s attention to detail.


From the farm’s perspective, the Stewarts commented that they were delighted with the end results. The Maxammon fed cattle saw impressive increases in daily gain as well as a substantial lift to the bottom third with cattle reaching carcass weight at least 20 days quicker than expected, as shown in the average daily gain figure in the table. Maxammon treated cereals now form an important part of the farm’s rations.
