StockMins – EweLamLac

Granular Lambing Supplement for Sheep


StockMins – EweLamLac is a weatherproof, granular, loose-lick supplement designed to support pregnant and lactating ewes at a time when essential minerals, vitamins and trace elements are in high demand. For best results, StockMins-EweLamLac should be fed from 4 weeks pre-lambing until 4 weeks post-lambing.

Product Description

  • Supplies a high-level calcium (18%) and phosphorus (4.8%) to support foetal development and milk production.
  • Contains high levels of available magnesium (5.5%) from four separate sources to match the sites of absorption and to meet the animal’s higher requirements during pregnancy and lactation.
  • Contains elevated levels of vitamins (A, D3 and E), minerals and essential trace elements necessary for optimum growth and performance at pasture in times of high nutritional demand.
  • Contains a high level of vitamin E for ewe health, immune-response and lamb viability.
  • Contains a high level of sulphur to aid in the reduction of wool break and stimulate fleece growth.
  • Acidic salts are included to moderate blood pH and aid in mineral mobilization.
  • Molassed and granular to improve palatability, control dust, reduce product losses and limit segregation.
  • Weather resistant to reduce water damage and leaching

Technical Note:

Magnesium requirements of ewes increase pre- and post-partum and magnesium deficiency can be prevalent around this time, especially during cold wet periods as climatic stresses set in. There is also a further elevated demand for magnesium in animals grazing cereal crops due to high levels of potassium which competitively bind to the same absorption sites, thereby decreasing magnesium utilization.

For every case of clinical grass staggers (magnesium deficiency) there are far more subclinical cases in the mob. Magnesium is primarily absorbed anterior (rumen and omasum) to the small intestine and it is therefore important that magnesium supplements address this. StockMins-EweLamLac does just this. Four sources of magnesium are used to supply magnesium to the various sites of absorption. One of these sources is in the form of an ‘acid salt’. This helps to increase magnesium availability through limited but significant mobilisation from skeletal reserves.

Calcium and phosphorus are also crucial minerals during lambing time. StockMins-EweLamLac provides elevated and available levels of these essential minerals.

Vitamin E, at levels that are considerably higher than RDI, has been shown to improve immune response, increase ewe vigour (less morbidity) and increase lamb survival and viability. StockMins-EweLamLac supplies high levels of Vitamin E and responses are quite noticeable.

StockMins-EweLamLac also supplies high levels of essential trace elements to meet demand for later stages of foetal development and lactation. Lambs also benefit significantly from trace element supplementation.

Sulphur, like carbon and nitrogen, is an essential nutrient required by rumen microbes for the synthesis of the sulphur containing amino acids (methionine and cystine/cysteine). Inadequate supply of sulphur to the rumen can cause these sulphur-dependent amino acids to become limiting, thereby impacting protein building, digestion and utilisation of feed. Keratin, the main protein found in wool, has a particularly high level of sulphur meaning that rapid fleece growth may require additional supplementation. Sulphur deficiency in sheep can result in wool break especially in combination with stress (weather, malnutrition or lambing). During late gestation and early lactation important minerals are diverted away from the ewe and portioned towards the developing foetus and lactation. Sulphur is no different. Supplementing sulphur pre- and post-partum can aid a reduction in ‘tenderness’ and wool break, stimulate follicle growth and ensure efficient building of microbial protein in the rumen.

Product Appearance

StockMins – EweLamLac appears as a granular, palatable and dust-free powder. It looks similar to sand with white flecks.  It is molasses coated and is weather resistant.

Target Animals:

Feed free-access (20 – 30grams per head per day) to ewes from 6 weeks to a month prior to lambing and continue feeding to ewes and lambs for at least 6 weeks post lambing. It may also be included in a mixed ration.

Feeding Instruction

Mixed Rations:- Mix 25kg of StockMins – EweLamLac per tonne of dry feed.

Free Access Feeding:-Offer free access in tubs limiting intake to around 20 – 30g/head/day once animals are fully adapted. Animals will control their own intake.

Use one tub for 50 – 60 sheep replenishing supplement as necessary.
