“…The presence of fat-tailed sheep breeds in both eastern Africa (Adal in Ethiopia, Somali in Somalia, Ethiopia, Djibouti and Kenya, Red Maasai in Kenya, Tanzania and Uganda, and Blackhead Persian in Somaliland) and southern Africa (Damara in Namibia and Afrikaner, Zulu, Van Rooy and Meatmaster in South Africa) suggests that this breed was successful in spreading widely across the continent. However, we should note that the sheep from Kerma have been described as 'long-legged hairy' and thin-tailed, with fewer caudal vertebrae than other thin-tailed sheep from Ethiopia, something that Chaix interprets as a primitive feature inherited from the mouflon [88][89][90]. Representations of thin-tailed sheep at Beni Hassan in Khnumhotep II's tomb during the Egyptian XIIth dynasty also attest to the presence of these animals in the northeastern part of Africa [91].…”

We report the first large-scale palaeoproteomics research on eastern and southern African zooarchaeological samples, thereby refining our understanding of early caprine (sheep and goat) pastoralism in Africa. Assessing caprine introductions is a complicated task because of their skeletal similarity to endemic wild bovid species and the sparse and fragmentary state of relevant archaeological remains. Palaeoproteomics has previously proved effective in clarifying species attributions in African zooarchaeological materials, but few comparative protein sequences of wild bovid species have been available. Using newly generated type I collagen sequences for wild species, as well as previously published sequences, we assess species attributions for elements originally identified as caprine or ‘unidentifiable bovid’ from 17 eastern and southern African sites that span seven millennia. We identified over 70% of the archaeological remains and the direct radiocarbon dating of domesticate specimens allows refinement of the chronology of caprine presence in both African regions. These results thus confirm earlier occurrences in eastern Africa and the systematic association of domesticated caprines with wild bovids at all archaeological sites. The combined biomolecular approach highlights repeatability and accuracy of the methods for conclusive contribution in species attribution of archaeological remains in dry African environments.

“…Sheep production is a strategic branch of animal husbandry and has an important place in many countries, although sheep production varies according to market demand [1]. For many years, sheep have been raised by societies for their meat, milk, and wool due to their behavioral characteristics and high adaptability to the environment [2][3][4]. Their tail structures, one of the main features that distinguish sheep breeds, can be used as an energy store for the animals to cope with harsh environmental conditions [5][6][7][8].…”

Products obtained from sheep have an economically important place in the world. Their adaptability to different climatic conditions, their ease of care and feeding, their high utilization of poor pasture areas with low yield and quality, the ease of flock management, their high twinning rate, and their short intergenerational period are some of the advantages of sheep production. Sheep production has the ability to adapt better to environmental stress factors, as can be understood from the presence of sheep in different geographical regions at a global level. However, the changes in environmental conditions and production cause some negative results in animals. All these negative results expose animals to various stress factors (heat, cold, transport, treatment, nutritional, shearing, weaning, etc.). All stress factors that directly and indirectly affect sheep production ultimately lead to compromised performance, decreased productivity, increased mortality, and adverse effects on the immune system. In order to cope with the current stress parameters in animals and to achieve optimum production, a holistic approach is needed according to the environmental conditions and available resources. It is important to consider the factors involved in these responses in order to manage these processes correctly and to develop adequate strategies and improve sheep welfare. This review aimed to reveal the importance of some stress factors in sheep and their effects on sheep productivity.
