The first sign that something was amiss with these calves is that they went off their feed. But they are back grubbing-up again.
We took the bull away from the replacement heifers last week. We just leave the bull with these heifers for eight weeks.
I always think that, if a healthy maiden heifer doesn't go in calf within eight weeks, she is not going to survive in the main herd as she has been shown up as a slow breeder.
These heifers will be scanned in a month's time and any showing up not in calf will be fattened off.
Our 16-month-old heifers have settled into the shed well and, at the moment, they are on 18kg of good quality first cut silage at 82 DMD, 4kg of meal and .5kg of straw.
These heifers will be finished out of the shed. So they will probably be slaughtered between April and early June. Some of them are well muscled heifers with a lot of potential to carry weight so we need to maximise their potential.
We will keep them going on the above diet well into the spring, at which point we will move over to a lot more concentrate and a lot less silage, going for an intensive 50-90 day finish, depending on the particular heifer.
The next job we need to do with these is put them through the crush, trim their tails, clip their backs and weigh them.
The sales of our under 16-month bulls are continuing on a weekly basis.
We are absolutely delighted with the fat scores. Without exception, they have all had a fat score of 3- or better, with a couple running into 4-.
Their weights are also holding up well. At the moment, we are averaging around 400kg carcase, though I know that will tail off a little for the tail end of the group.
All the bulls were weighed in the first week of August, while they were getting their IBR shot. We are also weighing them the day before they go to the factory.
The average daily weight gain over the period has ranged from 1.22kg/day to 1.97kg/day. This is a difference of .75kg/day which, at a 60pc killout, is almost .5kg of carcase per day. This shows that the best performing bull was increasing in value by almost €2 per day more than the worst performer, which is a sobering thought.
So I promise myself this year that, when all the bulls are gone, I will print off a sheet of their performance. We need to identify the dams of the best performers and the dams of the worst performers and see if there is a pattern.
All stock are housed now. As the bulls go to the factory, this has freed up some space to bring in the last remaining stock that were outdoors, the maiden heifers.
As most of the beef bulls will be gone by the middle of January, this dovetails nicely with the removal of the stock bulls from the cows, as it means we will have individual pens for them on the slats.
As this is my last column of 2017, I'd like to wish everyone a happy and safe Christmas.
