With regards to in lamb ewes low feed levels can cause a number of problems: – Reduced twin lamb birth weight – Sleepy sickness – Reduced ewe milk production – Reduced liveweight gain – Increased metabolic disease During the last 6-8 weeks of pregnancy the growth of lambs places an extra burden on the ewes and if these increased feed requirements are not met the ewes body fat reserves are used to provide energy for the lambs. A number of measures can be put in place, which may help manage feed shortages. In a feed deficit situation the cost of underfeeding twin bearing ewes is far greater than underfeeding single bearing ewes (until lambing that is). Dont forget twin-bearing ewes require increased feed in the last few weeks of pregnancy. Drystock could be removed if feed is short. Current market prices are favourable to this and the feed that this stock would consume could be more profitably diverted into grazing the lambs. If you have not done so already consider the application of Nitrogen based fertilizer. Nitrogen applied as urea is probably the best option. If ewes are currently in good body condition then they can probably be kept tight at the moment and/or supplement offered with the purpose of achieving some pasture growth in the lambing paddocks prior to set stocking. Try to avoid sudden changes in the amount and type of diet as they make sleepy sickness and milk fever more likely. If ewes are to be supplemented at this stage then grain is energy dense and is probably the best supplement to offer. Try to avoid Brassica crops at this late stage in pregnancy as they can result in iodine deficiency. Silage is better than hay but both are more suited to middle rather than late pregnancy.
