“…Small ruminants, such as sheep and goats, seem promising to overcome this problem because of their ability to thrive in water-restricted areas and adverse environments. They have different morphological, behavioural, biochemical, cell, and molecular properties in the blood that allow them to live in other tropical conditions (Akinrinmade and Akinrinde 2012;Alam et al 2013;Mandal et al 2018;Akinmoladun et al 2019;Formiga et al 2020). Small ruminants, including sheep and goats, are recognised as ideal models of animals for climate change because of their remarkable endurance of thermal and drought, ability to thrive in limited pastures and resistance to disease (Nasri et al 2011).…”

Climate change is shifting rainfall patterns, air temperature, river flows, and sea levels globally, resulting in changes in ground and surface water quality due to salinization, especially in arid and semiarid regions. During dry periods, the main water quality issue is a high quantity of salt in the water. Whilst water with fewer than 3,000 mg/L total salts is beneficial to all livestock species, tolerances vary greatly based on conditions and circumstances. Understanding the normal salt tolerance of animals without harming their production and health is important for sustainable livestock production, especially in dry areas. Understanding the normal salt tolerance of animals without harming their production and health is important for sustainable livestock production, especially in dry areas. Thus, this review examined the physiological, behavioral, hematological, and biochemical responses of sheep and goats in dryland areas under climate change scenarios. Despite changes in physiological, blood, biochemical, feed and water intake, sheep and goats adapt to salinity levels to drinking water in arid environments. Adaptable and native breeds are known to be more tolerant of saline water than selected exotic breeds. Small ruminants experience a decrease in food intake and weight, a decrease in breathing rate, and an increase in blood metabolite concentration when the salt in their drinking water increases. The concept that native and adapted small ruminant breeds can withstand high water salinity is gaining popularity in scientific research worldwide. More research is needed to investigate the water tolerance capabilities of adapted breeds, especially in dry and water-saline regions affected by climate change.

“…There are many scientific pieces of evidence clarifying the particular traits of goats that help them to cope with environmental challenges in different types of ecosystems, which mostly include: first, the small body size of goats, which allows them to escape more efficiently from the high radiant heat load by using thermally buffered microclimates, as well as, a lower absolute requirement for energy, water, and home range [ 12 , 13 ]. Second, the unique capacity for employing behavioral plasticity and goats’ morphological features imparts them the clear advantage over sheep and cattle to cope with seasonal biotopes with a lack of both feed and water [ 14 , 15 ]. Lastly, when facing low-quality feed, they also are superior to cattle and sheep in their ability to digest dry matter and recycle nitrogen [ 16 ].…”

This review attempted to collate and synthesize information on goat welfare and production constraints during heat stress exposure. Among the farm animals, goats arguably are considered the best-suited animals to survive in tropical climates. Heat stress was found to negatively influence growth, milk and meat production and compromised the immune response, thereby significantly reducing goats’ welfare under extensive conditions and transportation. Although considered extremely adapted to tropical climates, their production can be compromised to cope with heat stress. Therefore, information on goat adaptation and production performance during heat exposure could help assess their welfare. Such information would be valuable as the farming communities are often struggling in their efforts to assess animal welfare, especially in tropical regions. Broadly three aspects must be considered to ensure appropriate welfare in goats, and these include (i) housing and environment; (ii) breeding and genetics and (iii) handling and transport. Apart from these, there are a few other negative welfare factors in goat rearing, which differ across the production system being followed. Such negative practices are predominant in extensive systems and include nutritional stress, limited supply of good quality water, climatic extremes, parasitic infestation and lameness, culminating in low production, reproduction and high mortality rates. Broadly two types of methodologies are available to assess welfare in goats in these systems: (i) animal-based measures include behavioral measurements, health and production records and disease symptoms; (ii) resources based and management-based measures include stocking density, manpower, housing conditions and health plans. Goat welfare could be assessed based on several indicators covering behavioral, physical, physiological and productive responses. The important indicators of goat welfare include agonistic behavior, vocalization, skin temperature, body condition score (BCS), hair coat conditions, rectal temperature, respiration rate, heart rate, sweating, reduced growth, reduced milk production and reduced reproductive efficiency. There are also different approaches available by which the welfare of goats could be assessed, such as naturalistic, functional and subjective approaches. Thus, assessing welfare in goats at every production stage is a prerequisite for ensuring appropriate production in this all-important species to guarantee optimum returns to the marginal and subsistence farmers.
