“…Lamb meat consumption in children with atopic dermatitis and multiple food hypersensitivity has resulted in signifi cant clinical improvements. Lamb meat has a special importance in infant nutrition, because it provides a unique [19][20][21][22]. These analyzes have shown that many factors in the production, such are diet, age of weaning, breed, sex and body weight, have effects on muscle fatty acid composition and sensory characteristics of lamb meat [15,23].…”

The objective of the study was to perform and evaluate the advanced phenotypic characterization of endangered Zackel sheep types, especially their productive potential and meat quality traits. Meat quality characteristics (m. longissimus dorsi) were evaluated in lambs of three types of autochthonous Zackel sheep: Sjenica sheep, Lipe sheep and Vlashko Vitoroga sheep, reared in traditional habitats in a sustainable management system. For the evaluation of sensory characteristics of lamb meat, quantitative descriptive analysis was performed according to ISO 6564:1985, i.e. structural intensity scale of seven points. All Zackel meat samples had an overall acceptability, the most favorable being in Sjenica sheep, with detected differences between Sjenica and Vlashko Vitoroga sheep (p<0.01), as well as between Lipe and Vlashko Vitoroga sheep (p<0.05). For the determination of fatty acids profi le the prepared samples were analyzed using gas chromatography. The results showed that all tested lamb meat samples contain favorable amounts of conjugated linoleic acid (CLA). The average content of conjugated linoleic acid was higher in Sjenica lamb meat compared with Lipe lamb meat, and the difference was signifi cant (p<0.01). It is also shown that examined samples of Sjenica, Lipe and Vlashko Vitoroga lambs, compared to many other exotic and local breeds, were characterized by preferable values of n-6:n-3 fatty acid ratio. Polyunsaturated fatty acid n-6:n−3 ratio difference between tested Zackel types was not signifi cant. The favorable fatty acid profi le, important for human health and especially for infant and children nutrition, raises the interest for sustainable production and conservation of Zackel sheep.

The Silesian Beskids (Poland), the westernmost part of the Carpathian Mountains is an area with long pastoral tradition. For centuries sheep grazed in clearings located among forested ridges have been an integral part of the mountain landscape and pastoral customs have become essential elements of regional cultural heritage. In the chapter, the history and the current state of pastoralism in the Silesian Beskids are presented. The specific pastoral system developed in the region, based on annual migration of flocks between summer highland and winter lowland pastures is described. Local breeds and specific regional sheep products are depicted. Furthermore, the importance of pastoralism for the environment, landscape and plant biodiversity is analysed and efforts to recover sheep grazing in the mountains after a period of a deep recession caused by social and economic transitions connected with the collapse of the communist system are presented. The approach to restoration of pastoralism is illustrated using a case study of a pastoral centre which combines traditional sheep grazing with cheese production, education and several activities to promote pastoral tradition.

“…High reproductive performance, carcass quality, and low input cost are important to ensure profitable production in sheep breeding (Macit et al, 2001). The efficiency of lamb production is affected by reproduction, mothering ability and milk production of the ewes, and growth rate and survival rate of the lambs (Rao & Notter, 2000;Mishra et al, 2007;Gavojdian et al, 2013).…”

The aim of this study was to evaluate the effects of cross-breeding Turkish indigenous Morkaraman (M) ewes with prolific Romanov (R) rams on the reproduction and performance traits, growth traits, slaughter and carcass characteristics of the crossbred offspring under semi-intensive production systems. No significant differences were observed between M and RxM for number of ewes lambing. The differences between M and RxM for number of lambs born alive, number of weaned lambs, number of lambs surviving up to 120 days, and up to the end of pasture were significant. Average birth, weaning, and post-grazing weights of lambs were 3.71 kg, 17.81 kg and 23.93 kg and 2.89 kg, 17.14 kg, and 22.32 kg in M and RxM lambs, respectively. The weight difference between M and R x M lambs at birth and at the end of the grazing period was significant. M had higher end-of-pasture and slaughter weight. After the grazing period, the slaughter characteristics of ram lambs were investigated. The differences between M and RxM lambs were significant for weight of slaughter, hot and cold carcass, tail fat, and organs (testis, heart and lung). Additionally, M lambs had a larger longissimus dorsi area than RxM lambs. It was evident that the M lambs had higher growth and slaughter values and some carcass characteristics than RxM crossbred lambs. It was concluded that, under the climate and management-nutritional conditions of the region, purebred M is a more suitable breed than RxM crossbreds.
