Early Lamb Production Systems

Abstract

A number of feeding and management options for early lambing flocks were evaluated at the Knockbeg Sheep Unit, Carlow. Results and recommendations for on-farm adoption are summarised in this report. The ultimate objective was to develop cost-effective early lamb production systems in synchrony with the high price season from late March to early May. Studies were focused on the two main phases of lamb growth. Firstly, the period from birth to 6 weeks of age which coincides with the critical period of lamb survival and peak lactation in the ewe and, secondly, the finishing stage from 6 weeks until slaughter. Flock size was 230 to 250 ewes sponged in July/August for lambing in January and managed on 12.6 ha of grass and forage. The results provide options in feeding and management for programmed lamb production in synchrony with early season prices. The production technologies are effective, e.g. out-of-season breeding, grass utilisation, planned schedules for achieving high levels of feed intake and lamb performance, drafting procedures for selecting high quality lambs (Fat class 3, Conformation classes U and R). On-farm planning for feeding, housing and labour is essential.
