| Sheep Lambing preparation key to success In advance of the lambing season, farmers are advised to take a proactive approach to maximise ewe performance and live lambs. he majority of lamb losses occur during the first 48 hours of life, but this could be avoided by focusing on an effective colostrum management programme, says Nia Williams, Nettex technical manager. “Newborn lambs have a limited supply of energy,” she says. “So by ensuring lambs have rapid access to a quality source of colostrum, whether from the ewe, or from an artificial source, is T crucial for lamb survival and their ability to thrive.” Research from the Scottish Rural University College (SRUC) has shown that over the course of the first 18 hours of life, lambs require at least 250ml per kg birth weight of colostrum to meet energy requirements, and prevent hypothermia. However, at least 300ml of this should be consumed within the first six hours of birth to provide disease immunity. “Not all ewes are able to deliver New sheep tagging rules in force New sheep tagging rules mean care must be taken in the New Year, says NSA. he National Sheep Association urges sheep keepers in all parts of the UK to be aware that new rules for sheep identification come in on Thursday 1st January 2015. The derogation from Europe protecting ewes and rams tagged before 2010 (‘the historic flock’) from EID rules is coming to an end and so, from 1st January, these animals must be individually identified on movement records unless they going directly to an abattoir or via a red market. NSA stresses that the end of the derogation does not mean animals from the historic flock have to be retagged with full EID, but many producers may choose to take that step if it makes it easier for them to move older ewes and rams from the historic flock between farms or via markets. Phil Stocker, NSA Chief Executive, says: “It is not a legal requirement to retag ewes and rams from the historic flock with electronic identifiers, and we are not for a minute suggesting a gold plating of the rules. What we are saying is to carefully consider what moves you are likely to make with older animals in the future and, if these will not be direct to slaughter, doubletagging is likely to be the sensible option. It makes sense to do this when you are handling sheep in the coming months – and don’t forget to make a note T in your flock register.” Also from 1st January 2015, sheep keepers in England are no longer permitted to use nonEID tags for lambs and must use a single EID slaughter tag in lambs not being retained for breeding. Lambs born before 1st January are still permitted to carry a non-EID tag and there is no requirement to retag these animals. Use of the non-EID slaughter tag is still permitted in Wales until January 1st 2016, but NSA urges sheep keepers in Wales to be very careful about the tagging decisions they make in 2015. Mr Stocker says: “It is has always been important to use the non-EID slaughter tag in prime lambs only and not in store lambs, but this will be even more important for Welsh farmers in 2015, as they will be the only nation still using the non-EID slaughter tag and will reduce their selling options if they use plastic tags in lambs that may be bought for further finishing.” One final reminder for all sheep keepers is to keep an eye out for their Sheep and Goat Annual Inventory and return it before the deadline. Businesses in England will be the first to receive their paperwork, which needs to be returned by Wednesday 31st December. For farmers in Wales, Scotland and NI the deadlines are not until 2015. 50 | Farming Monthly | January 2015 a quality source of colostrum in sufficient quantities for their lambs. By planning ahead, farmers can make sure they have an effective colostrum substitute on-hand and ready for if and when it’s needed,” she says. When choosing a colostrum supplement, Nia advises farmers to follow Nettex’s five-point guide. “Firstly, check if the colostrum contains a high digestible fat content. “Secondly, look to see if the substitute contains egg proteins. The additional active proteins help support immune development and natural defences to common diseases. “Does it include pre and probiotics, and is the colostrum easy to mix and consistent in colour, are the final questions that should be considered,” she says. This advice can be used as a checklist when choosing a colostrum ahead of lambing to ensure the artificial source mimics the ewe’s own colostrum as far as possible. Ultra Concentrate from Nettex, is a quality, easy-mix colostrum fortified with ewes milk, providing energy and support to weak and small lambs when needed. A 25g dose provides lambs with a protein rich, nutritional source required in the first hours of life. Shropshire Sheep are traditional, productive and tree friendly Shropshire Sheep, the oldest pedigree breed in the UK, have seen a revival in numbers over the past decade. The growth in popularity amongst sheep producers across the globe can be credited to the productivity and versatility of the breed. he breed is particularly popular amongst smallholders who are attracted by their quiet nature, ability to finish off grass and their good quality wool, which is suitable for hand-knitting yarn. Shropshires produce excellent butcher’s lambs from grass-based, low input systems. In fact, Shropshire lambs are producing excellent carcasses, on par with those produced by many other terminal sire breeds used in this country. Many keepers run small flocks and sell their lamb boxed direct to the public or rear for their freezer.
