Forward Thinking in Late Pregnancy Maximises Lamb Productivity

With the main lambing season fast approaching, it is critical we start planning ahead for the feeding management of the pregnant ewe.

During the last 6 – 8 weeks of pregnancy, ewes need to be on a rising plane of nutrition to compensate for the rapid increase in lamb growth, and reduction in dry matter intake (DMI). The requirement to meet this energy deficit through targeted concentrate feed allocation in the weeks leading up to lambing helps reduce the risk of metabolic disorders and facilitates adequate colostrum and milk production post lambing.

To assess what the diet is providing, we advise that a forage analysis is carried out and used to balance the diet with the appropriate concentrate. Many forages are testing lower in protein this year, so a higher protein concentrate may be required to ensure protein requirements are met. Fane Valley Feeds’ use high-quality raw materials in their ewe feeds, including soya bean meal, providing an excellent supply of rumen bypass protein that improves ewe colostrum quality, milk let down and supporting the viability of newborn lambs.

Concentrate feed rates before lambing are targeted by scanning results and body condition score (BCS). Ewes carrying multiple lambs require more energy and protein to support additional requirements from fatal growth. While singles, although still needing to be supplemented, the rate of concentrate feeding will be lower compared to those carrying multiples. This targeted feeding reduces incidences of negative energy balances (‘twin lamb disease’).

Although the goal is to keep ewe body condition score (BCS) consistent year-round, with little variation across the flock, it is essential to monitor and batch ewes accordingly. For ewes in optimal condition (BCS 3) the focus is more on maintaining their condition rather than gaining or losing with feed rates solely based upon litter size.

  • Low BCS (<3): Increased concentrate feeding earlier and in larger amounts per day, especially for ewes carrying twins or triplets.
  • High BCS (>3): Cannot be altered in late pregnancy, concentrate feeding treated similarly to that of normal or lower BCS ewes. Complication can arise as DMI is reduced in these ewes.

Colostrum is also vital to lamb health and survival. Ideally lambs should suck within 30-40 minutes of birth and require the equivalent of 50 ml/kg birthweight. The high inclusion of by-pass protein in Fane Valley Feeds’ Ewe Nuts helps to maximise colostrum production and prepares udder tissues for lactation.

Advancing animal nutrition Fane Valley Feeds have developed a unique product included in their ewe feed range, which increases the immunoglobulin content of colostrum maximising immunity prior to the lamb developing its own immune system. The Fane Valley Feeds mineral package is specifically formulated to ensure industry leading levels of Vitamin E, as well as elevated Selenium, Iodine and Cobalt to produce vigorous lambs which are ready to suckle.

Fane Valley Feeds have a complete range of concentrate sheep feeds available to meet the requirements of local sheep farmers.  Our products are nutritionally balanced to meet the energy and protein requirements of high production ewes, and our targeted approach helps offer a tailored solution.
