“…In response to thermal stress, animals regulate their energy metabolism by adjusting feed intake in terms of variety and quantity when they deviate from the optimal body temperature range for cellular processes [ 59 , 60 ]. Moreover, animal morphology displays variations, including body size, that align with essential thermoregulatory principles to manage body energy in different climates effectively.…”

Goats have achieved global prominence as essential livestock since their initial domestication, primarily owing to their remarkable adaptability to diverse environmental and production systems. Differential selection pressures influenced by climate have led to variations in their physical attributes, leaving genetic imprints within the genomes of goat breeds raised in diverse agroecological settings. In light of this, our study pursued a comprehensive analysis, merging environmental data with single nucleotide polymorphism (SNP) variations, to unearth indications of selection shaped by climate-mediated forces in goats. Through the examination of 43,300 SNPs from 51 indigenous goat breeds adapting to different climatic conditions using four analytical methods: latent factor mixed models (LFMM), F-statistics (Fst), Extended haplotype homozygosity across populations (XPEHH), and spatial analysis method (SAM), A total of 74 genes were revealed to display clear signs of selection, which are believed to be influenced by climatic conditions. Among these genes, 32 were consistently identified by at least two of the applied methods, and three genes (DENND1A, PLCB1, and ITPR2) were confirmed by all four approaches. Moreover, our investigation yielded 148 Gene Ontology (GO) terms based on these 74 genes, underlining pivotal biological pathways crucial for environmental adaptation. These pathways encompass functions like vascular smooth muscle contraction, cellular response to heat, GTPase regulator activity, rhythmic processes, and responses to temperature stimuli. Of significance, GO terms about endocrine regulation and energy metabolic responses, key for local adaptation were also uncovered, including biological processes, such as cell differentiation, regulation of peptide hormone secretion, and lipid metabolism. These findings contribute to our knowledge of the genetic structure of climate-triggered adaptation across the goat genome and have practical implications for marker-assisted breeding in goats.

“…Water sources dry up while pastures become depleted due to prolonged dry periods and less rainfall [30,31]. However, some studies have shown that goats withstand harsh climatic conditions like high temperatures and drought better than large stock and other small ruminants [20,32,33]. Even under extreme climate conditions, goats are considered worth investing in because they have the potential to transform the lives of the poorest in developing countries, where 90% of the global goat population is concentrated [34].…”

The changing climate has a serious bearing on agriculture, particularly livestock production in Botswana. Therefore, studying the relationship between climate and livestock, which at present is largely missing, is necessary for the proper formulation of government policy and interventions. This is critical in promoting the adoption of relevant mitigation strategies by farmers, thereby increasing resilience. The aim of this research is to establish associations between climate variability and livestock production in Botswana at the national level. The paper employs time series data from 1970 to 2020 and the Vector Autoregression with Exogenous Variables (VARX) model for statistical analysis. The trend shows that both cattle and goat populations are decreasing. The VARX model results reveal that cattle and goat populations are negatively associated with increasing maximum temperatures. Cattle respond negatively to increased minimum temperatures as well, while goats tend to respond positively, implying that livestock species react differently to climatic conditions due to their distinct features. The results of the roots of the companion matrix for cattle and goat production meet the stability condition as all the eigenvalues lie inside the unit circle. The study recommends further intervention by the government to deal with increasing temperatures, thereby addressing the dwindling populations of goats and cattle, which have significant contributions to the household economies of smallholders and the national economy, respectively.

“…Goats are preferred to be raised in desert environments, such as Saudi Arabia, because their nutritional needs are lower than those of cattle (Daramola et al, 2021;Al-Suwaiegh et al, 2020). Goats have a higher capacity to convert low-quality feed into high-quality products with higher economic returns than other animal species (Daramola et al, 2021). Due to these benefits of raising goats in harsh environments, the rates of goat productivity are acceptable, and young breeders have a good opportunity to initiate a goat-raising project (Joy et al, 2020).…”

Background: Among the different range animals, goats can adapt and survive greatly under harsh environmental conditions. The aim of this study was to investigate the effect of using a mixture of garlic and ginger as supplementation to improve the growth performance and nutrient digestibility of Ardi goats. Methods: A total of twenty Ardi goats (40.35±1.8 kg) were assigned randomly into four experimental groups. The first group received a basal diet (control), the second to fourth groups were dietary supplemented with a mixture of garlic and ginger at the different levels of 20, 40, and 60 g/animal/day, respectively for 12 weeks. Result: There were no significant differences in the final body weight and feed conversion ratio of goats fed different levels of dietary supplemented of ginger and garlic mixture. The TDMI and daily DMI significantly reduced in groups fed diets supplemented with 20 and 40 g/animal/day than the control group. The digestion coefficients of CP, fiber fraction digestibility, and TDN values decreased in different groups. In conclusion, the addition of ginger and garlic mixture at the studied levels did not significantly affect animal performance and had negative impacts on feed utilization and nutrient digestibility.
