TEFRom sheep are a composite breed developed by crossing Texel, East Friesian, and Romney sheep, aiming to enhance lamb growth rates while ensuring efficient ewe performance. This composite sheep breed was strategically developed based on the following proportions:
- 25% Texel: selected for superior muscling, resistance to parasites, and a clean under the tail.
- 25% East Friesian: chosen for its high fertility, with a base of 230%, and strong milking ability.
- 50% Romney: included for its stability, robust constitution, fleece weight, as well as a balance of growth rate, fertility, and muscling.
This carefully crafted combination ensures that TEFRom sheep exhibit desirable traits from each parent breed, resulting in fast lamb growth and efficient ewe performance. The breed's development aimed to optimize key characteristics essential for successful sheep farming.
