“…Work on early weaning of younger lambs (2-4 weeks) has been carried out in countries where ewes' milk is used for cheese and yoghurt. Under such circumstances, early weaned lambs have been regarded as a by-product of relatively low value (Charlet-Lery & Zelter, 1955), but recently more interest has been shown in the economic potential of this type of lamb (Charlet-Lery, Leroy & Zelter, 1954;Charlet-Lery & Zelter, 1955;Jacquet, 1962). In Israel, lambs may be given access to the ewe at night only (Volcani & Eyal, 1953), and are usually weaned at 8-10 weeks.…”
