Artificial Lamb Rearing: Part 1 – A Producer Project

From March to August 2022 an on-farm project on artificial rearing systems specifically focusing on milk machines and lamb performance was conducted at several Ontario farms. The project had three main objectives: lamb productivity, rearing cost, and producer labour. The results will be presented in a series of articles; this article will focus on-farm set-ups, machine cleaning and milk replacer cost.    Six farms participated in the project. Two farms had Lac-Tek milk machines and four farms had Eco Feeders also commonly known as Förster-Technik and / or Grober refer to Figure 1. The total number of ewes represented on the farms was 3395, with flock sizes of 400, 825, 120, 1000, 450 and 600 respectively. Two farms kept artificially…

Colostrum Requirements for Lambs

Spring lambing is quickly approaching. Ideally, a lamb should receive 50 ml per kg of bodyweight of its own mother’s colostrum, within 1 hour of birth. Additionally, 150 ml per kg spread over three more feedings within the first 24 hours of life should be provided.  If you do ‘inherit’ some bottle babies, the total daily feeding rate should be no more than 10% of a lamb’s own body weight, and in as many as four feedings per day. Appropriate feeding frequencies at a given age are listed below. Recommended feed source, and frequency of milk replacement (M.R.) feeding for lambs from birth to weaning Age (days) Feed Source M.R. Frequency 0 -24 hr. Colostrum 4 to 5 times* 1 –…
