“…Small ruminants became much more vulnerable to different metabolic disorders (Sejian et al, 2021). Late stage of gestation in small ruminants have enormous energy demands that led to start fat tissue mobilization, which is internal sources because of the increased energy requirements of advanced pregnancy which resulted in negative energy balance, production of ketone bodies and ultimately severe hypoglycemia (Zamuner et al, 2020).…”

The aim of our study was to describe the B-mode hepatic ultrasonography of does with subclinical pregnancy toxemia and shed the light on the hematological and protein profile alterations. Based on the blood serum levels of glucose, pregnant does were classified into; Group 1: Thirty pregnant does were used as controls (Their glucose levels were more than 40 mg/dL). Group 2: Twenty-five does were diagnosed as subclinical pregnant toxemic (SCPT) since their glucose values were <40 mg/dL. B-mode of the diagnostic ultrasound scanner was used. Special kits were used for the determination of glucose, total protein and albumin. Liver B-mode ultrasonography of does with SCPT indicated by fatty infiltration among hepatic parenchyma. Rounded margins which were indicated by hepatic enlargement. subclinical pregnancy toxemic does showed significant decreases of RBCs, Hb, MCV, MCH and MCHC and significant increases of PCV, leukocytes, neutrophils and lymphocytes than healthy control pregnant does(P ≤ 0.05). A significant decrease of serum total protein, albumin, and A/G ratio were recorded in subclinical pregnant toxemic does when compared to healthy control one.

“…Small ruminants, such as sheep and goats, possess a high level of adaptability to a wide range of agro-ecological regions. Moreover, goats have a relatively high capacity for disease resistance, allowing them to thrive better in harsh conditions [43].…”

“…Different strategies should be developed and implemented at the international level to counteract the negative effects of climate change on livestock. Crossbreeding of native sheep and goats with high-yielding breeds may play an important role in the mitigation process [43]. Recent advances in molecular genomic expression technologies make it possible to identify candidate gene regions associated with thermo-tolerance [44].…”

Conservation and Selection of Genes Related to Environmental Adaptation in Native Small Ruminant Breeds: A Review

et al. 2022

Environmental stressors have, over generations, influenced the morphology, anatomy, behaviour, physiology, and genetic structure of small ruminants. The widespread dispersal of small ruminants over vast geographical areas occurred along with human migration, thereby promoting the adaptative process to different environmental conditions mainly through natural selection. Ongoing global warming prompted scientific efforts to deepen the knowledge and understanding of adaptation traits in small ruminants. Compared to other ruminants, sheep and goats seem to have a better adaptation ability to environmental stressors, as evident by their presence across different geographic areas on a global level. Adaptation to a specific environment leads to variations in precise genomic regions, allowing for the identification and selection of animals with a high capacity of adaptation to environmental stressors. Rapid development in sequencing technologies, together with bioinformatics tools, make it possible to analyse the genomic regions related to environmental adaptation. Hence, the aims of this review were (i) to outline the main steps of the evolution process in sheep and goat species, (ii) to summarise candidate genes related to environmental adaptation, and (iii) to evaluate both selection and conservation possibilities of these genes in native small ruminant breeds for future challenges to better face the global warming.

“…High temperature stress can affect hormonal stress markers such cortisol. Additionally, the sympathetic-adrenal–medullary ( SAM ) and hypothalamic-pituitary-adrenal ( HPA ) axis are activated to maintain redox homeostasis and immune functionality in response to stress ( Sejian et al, 2021 ). During acute periods of HS, the production of cortisol hormone may serve as a trigger for the immune system.…”
