Achievement of lamb growth targets starts with the right preparations ahead of lambing. What happens from scanning through to the first four to six weeks of ewe and lamb nutrition has a huge influence on lamb daily live weight gain (DLWG) and how quickly they can leave the farm.
In episode 3 of Wynnstay Agri-Hub podcast, season 2, I was joined by youngstock specialist Laura Monk and national beef and sheep specialist Bryn Hughes to look ahead to prepare for the upcoming lambing season. We talked through the critical stages which influence lamb success, starting with ewe nutrition during pregnancy.
Two thirds of all joint ill cases are caused by the bacteria Streptococcus Dysgalactiae – the same bacteria that causes mastitis in cows. The other third of cases are preventable through adequate colostrum uptake.
Weaning can be considered a simple change from milk feeding to solid feeding but in truth it is a balancing act between maximising early feed efficiency and managing rumen development.
In mid-season lambing flocks, the aim is to get lambs to 32 to 42kg as soon as possible, capitalising on early feed conversion efficiency (FCE). Investing in early nutrition to capitalise on this early growth potential will pay dividends.
With the fortnight of Eid celebrations commencing in mid-July, those who lambed early to mid-March need to get lambs finished quickly to ensure they don’t miss market opportunities.
We are all aware of the importance of ewe colostrum as the first feed and antibodies has always been the ‘buzz’ word, however, successful colostrum feeding is a considerably bigger picture.
During late pregnancy a ewe’s immune system becomes weakened, therefore the worm burden that is usually kept subdued can flourish and an increased number of worm eggs can be released onto the pasture.
