How was your 2016/17 lambing season?



How was your 2016/17 lambing season?

At the end of 2016 we asked you to tell us about your surplus lamb rearing practices. More than 45% of you saw an opportunity to rear more lambs artificially this year as you gear up to take advantage of a potentially changing market environment.

And there’s no doubt that many of you have put this intention into practice. Interest in automatic milk feeding machines sales has been phenomenal this year and we have helped many new sheep farmers take advantage of the benefits that come with machine rearing. As a result, many more producers now understand that surplus lambs can be reared very efficiently artificially and without the problems associated with fostering onto an unwilling ewe. With good husbandry, organisation and the right milk replacer, there’s no doubt you can produce good quality lambs, as well as save hours of effort and hassle. You’ve proved it for yourselves.

We hope your new lambs are now growing fast and that the welcome rainfall for many during the second half of May has given pasture grass growth a timely boost.

Weaning surplus lambs

For late season lambers, don’t forget to wean and surplus lambs correctly over the coming weeks. Any lambs fed on Lamlac milk replacer should be:

  • A minimum of 2.5 times their birth weight (9-10kg), so typically about 25kg
  • A minimum of 35 days old
  • Consuming 250g of solid feed per day for a three day period

Weaning of surplus lambs reared artificially is most successfully achieved when Lamlac is withdrawn abruptly, provided that lambs are old enough and that intake of solid feed is adequate. Lambs should have been eating solid feed for at least 10 days and be making use of the drinking water supply.

Weaning lambs off the ewe (AHDB Beef)

From eight weeks of age at pasture a lamb's energy intake is greater from grass than from milk. At this point the competition between ewes and lambs for high-quality grass reaches a critical point. Grazing management and grass growth will differ year on year so the ideal weaning date cannot be set in stone; figures from the AHDB Beef and Lamb Stocktake survey suggest lambs are usually weaned off their mothers at between 12 and 14 weeks of age.

If grass is growing well and ewes are in good condition, weaning can be delayed without reducing lamb liveweight gain. However, if forage availability is low, lamb growth rates will suffer, as ewes and lambs compete for the same grass.

AHDB Beef and Lamb advises:

  • If lamb growth rates are lower than 200g per day, this should trigger weaning and lambs should be moved onto better quality forage.
  • If creep feed is being fed, liveweight gain may not decline after eight weeks, so weaning decisions should be based on how long the lambs have until they are finished as well as ewe condition.
  • High quality grass with lots of green leaf and limited stem and dead matter will be greater than 11.5 MJ of ME compared to less than 8 MJ for grass with high degree of dead matter and stem.
  • Dry matter intake is calculated at four per cent of bodyweight, for example, a 30kg lamb consuming 1.2 kg DM per day with access to 11.5 MJ forage will be consuming 13.8 MJ per day and should be gaining more than 250g per day.
