Choosing the right time for AI and taking advantage of estrus synchronization can help small scale farmers to increase their income with low input. A good practice is to have calving commencing 4 to 6 weeks before the start of the spring rains. AI will then commence 6 to 8 weeks after the first rains have fallen, when the veld has had time to become green and has grown out enough to support the needs of the cow and her calf. The cow’s nutritional needs are at a peak 2 – 3 month after calving. Her milk production is at a maximum and she needs effective nutrition to provide for milk production as well as to build up her body reserves after the winter.
