A recent study conducted at the Mara Research Station in Limpopo has revealed important information about how different types of Nguni cattle perform under varying conditions. This research provides practical guidance for farmers looking to optimise their herds for South African conditions.
The study focused on three distinct types (ecotypes) of Nguni cattle found in Limpopo Province: the Venda cattle (medium-sized, compact bodies), Pedi cattle (larger-framed animals) and Shangaan cattle (smaller-bodied animals). These indigenous cattle types have adapted to local conditions over generations, but until now, little was known about their specific performance differences.
Researchers tracked 471 calvings between 2009 and 2013, measuring calf birth weights, weaning weights, time between calvings, how quickly cows became pregnant again after calving, cow weights at breeding and weaning and overall weaning efficiency (how much calf weight a cow produces relative to her own weight).
The study also examined how rainfall variations across years affected cattle performance, with annual rainfall ranging from a dry 310mm in 2011 to a wetter 620mm in 2009.
This research highlights the importance of South Africa’s indigenous cattle diversity. Rather than seeking a single “best” type of Nguni cattle, farmers can benefit from understanding the unique strengths of each ecotype.
The study confirms what many traditional farmers have observed: Our local Nguni cattle are extraordinarily well-adapted to South African conditions, but different types excel in different environments and for different production goals. By selecting the appropriate Nguni ecotype for their specific farm conditions and market goals, Limpopo farmers can enhance both the sustainability and profitability of their cattle operations.
Key findings for farmers
Venda cattle: These medium-sized, compact animals showed some impressive traits. They produced calves with lower birth weights (24kg), which is good for preventing calving difficulties. Their calves showed excellent growth, reaching good weaning weights (144kg). It’s a good choice for farmers wanting smaller calves that grow quickly.
Pedi cattle: The larger-framed option for maximum production. Produced the heaviest calves at birth (25.5kg). Had the highest weaning weights (157kg). Best choice for farmers primarily focused on producing heavier calves for the market.
Shangaan cattle: The smaller but resilient option. Lightest cows (about 331kg compared to 355kg for others). Calves had moderate birth weights (25kg) but lower weaning weights (136kg). Showed remarkable ability to handle tough conditions and it excelled during drought years with better reproduction rates.
The weather factor
A major discovery was how rainfall significantly affected all cattle types. In wet years, all ecotypes performed better with higher birth weights, weaning weights and faster rebreeding, while in dry years the smaller Shangaan cattle outperformed the larger ecotypes in key areas such as shorter time between calvings, quicker return to pregnancy and better weaning efficiency (more calf weight produced relative to cow size).
Practical advice for Limpopo farmers
Matching cattle type to your farm conditions
For farms in drier areas with frequent droughts farmers may consider Shangaan cattle for their remarkable ability to maintain reproduction even when grass is scarce. Their smaller size means they need less food to maintain condition. While individual calves may be lighter, their reproductive efficiency may mean more total production.
For farms with reliable rainfall or good supplementary feeding Pedi cattle can maximise production with their higher weaning weights while Venda cattle offer a good balance with lower birth weights but good growth rates.
Management tips based on research
- Rainy season strategies: All ecotypes perform well during good rainfall years. Invest in better management during these periods to maximise the natural advantage. Higher stocking rates may be possible.
- Drought planning: Larger-framed Pedi and Venda cows may need more supplementary feeding during dry periods. Reducing stocking rates earlier for larger ecotypes may preserve performance. Shangaan cattle can maintain better reproduction with less supplementation.
- Breeding goals: For farmers concerned about calving difficulties, consider Venda cattle with their lower birth weights. For maximum weaner weight, Pedi cattle produce the heaviest calves. For reproductive efficiency in harsh conditions, Shangaan cattle maintain shorter calving intervals.
Economic implications
The right ecotype choice can significantly impact farm profitability:
• Production costs: Smaller Shangaan cattle may require less feed supplementation during drought, reducing costs.
• Market returns: Pedi cattle may fetch higher prices due to heavier weaning weights.
• Herd turnover: Shangaan’s shorter calving intervals in tough conditions may mean more calves over time.
• Risk management: Matching ecotype to your farm’s typical rainfall pattern provides insurance against bad years.
