Considering climate change, unpredictable weather patterns, and rising production costs, South African farmers may need to rediscover the remarkable value of indigenous goat breeds.
These animals, shaped by centuries of natural selection rather than human intervention, demonstrate extraordinary adaptability, ideally suited to thrive in some of the country’s most challenging landscapes.
Indigenous goat breeds represent a living repository of genetic adaptations that have evolved over countless generations. According to recent genomic research conducted by the Agricultural Research Council and leading universities, these adaptations are not merely anecdotal but encoded at the genetic level.
Adaptive genes
Dr Kennedy Dzama, a prominent animal scientist from Stellenbosch University, has noted in his work on indigenous livestock that “these animals carry adaptive genes that have been naturally selected for survival under harsh African conditions, making them invaluable genetic resources for sustainable farming in the face of climate change.”
Another groundbreaking study published in Diversity revealed distinct genetic differentiation between indigenous goat populations in the Eastern Cape, Limpopo, KwaZulu-Natal, and North West provinces. This genetic diversity reflects adaptation to specific agro-ecological zones and aligns with the historical migration patterns of African peoples (Molotsi et al., 2020).
Heat tolerance
Perhaps the most valuable trait of indigenous goats is their remarkable tolerance for heat and drought, a crucial advantage in a country where water scarcity is an increasing concern.
Research conducted by Dr Ntanganedzeni Mapholi at the University of South Africa has identified physiological mechanisms that enable indigenous goats to sustain productivity even during prolonged dry spells.
Prof. Nokuthula Kunene from the University of Zululand, who has extensively studied indigenous goat production systems, emphasises that the Indigenous Veld Goats have evolved under natural selection for traits that enhance their survival in harsh environments. Kunene states that their ability to withstand drought and recover quickly when favourable conditions return makes them particularly valuable in areas prone to erratic rainfall patterns.
Adaptability
A specific study on Nguni goats demonstrated their ability to adapt to regulated watering regimes that simulate water scarcity conditions while maintaining reasonable productivity levels that would be impossible for many exotic breeds (Mpendulo et al., 2023).
The economic burden of livestock diseases and parasites in South Africa is substantial, with treatment costs, production losses, and mortality significantly affecting farm profitability. However, indigenous goats display remarkable resistance to many endemic diseases.
Schalk van der Walt, a prominent breeder involved with the Indigenous Veld Goat Society of South Africa (IVGSA), emphasises the importance of maintaining animals in their original form and preserving the characteristics of each respective breed. “These are the goats that yielded the most profit.” His experience in selecting authentic indigenous veld goats over more visually appealing but less productive ones highlights the practical value of natural adaptation (AgriBiz, 2023).
Resistance to diseases
Indigenous goat breeds demonstrate resistance to major challenges, including tick-borne diseases, internal parasites, foot diseases, and respiratory conditions.
According to genomic research published in Frontiers in Genetics, this disease resistance is linked to specific genetic markers that have been naturally selected over time (Mdladla et al., 2022). These genetic adaptations enable indigenous goats to maintain productivity with minimal veterinary intervention, providing a significant economic advantage for small-scale and resource-limited farmers.
Additionally, these goats are exceptional browsers, utilising a wide range of plant species that other livestock cannot access or digest. This trait has significant implications for the animals’ nutrition and environmental management.
The Indigenous Veld Goat Society explains that these animals consume a diet consisting of approximately 60% browse and 40% graze, providing them with access to higher nutritional content than many other livestock species. Their digestive systems are specially adapted to handle tannins and other plant compounds that would be problematic for non-adapted animals.
“Indigenous goats can select high-quality diets even from seemingly poor vegetation,” says Prof. Este van Marle-Köster from the University of Pretoria, whose work spans genetic diversity in indigenous livestock.
“This selective feeding behaviour allows them to maintain adequate nutrition even when grasses have low nutritional value.”
So, rather than viewing these breeds as primitive or unimproved, modern science reveals the sophisticated genetic adaptations that make them ideally suited to African conditions. By embracing these naturally adapted animals, farmers can harness evolutionary wisdom that predates modern agricultural science.
In the words of the Indigenous Veld Goat Society, these goats are in the form as nature intended them to be – perfectly adapted to their environment through generations of natural selection. “Our role is not to ‘improve’ them, but to recognise and utilise their inherent value.”
As climate change introduces greater variability and extremes in weather patterns, the adaptive traits of indigenous goats become increasingly valuable. Researchers like Dr Ntanganedzeni Mapholi have identified these animals as critical genetic resources for developing climate-resilient livestock systems.
Indigenous goats represent generations of natural adaptation to environmental challenges similar to those we expect from climate change,” notes a study published in the Journal of Animal Science. “Their genetic traits for heat tolerance, drought resistance, and disease resilience may prove essential for sustainable livestock production in a warming world.
