The Boer crossbred sheep, produced by crossing Boer goats with local breeds, exhibit excellent growth performance and should be utilized to their full potential. Proper management is essential to maximize their productivity. Here are key points to consider:
First, it's important to improve the nutritional quality of the feed. These hybrid sheep grow rapidly, especially between 6 to 9 months of age, when their weight can double compared to local breeds. This means their nutritional needs are higher, so supplements should be added to their regular diet. Sheep born in spring usually have access to better forage, but during weaning periods or before marketing, they may need additional feeding. Without proper nutrition, early growth can be stunted, leading to poor overall development.
Second, effective management practices are crucial. Along with daily care, timely castration and regular deworming are necessary. Lambs are typically castrated around two months old. In spring and autumn, internal parasites like flukes and worms should be treated every two months. External parasites such as lice should also be controlled, with treatments done twice a year.
Third, short-term fattening is recommended one month before slaughter. Under normal grazing conditions, 6-month-old hybrid sheep can be fed 150 grams of corn, 100 grams of bran, 50 grams of soybean pods, and 3 grams of bone meal daily. After about a month of this feeding regimen, they can gain 6 to 8 kilograms, improving meat quality and market value.
Fourth, these sheep grow quickly, and many reach weights of 25 to 30 kg between 6 and 9 months. Even those born in the fall can reach 20 kg by 4 months if given proper nutrition. Planning breeding times effectively ensures that lambs are ready for market within the same year, which is an important factor for farmers aiming for efficient production cycles.
Lastly, using feed additives can enhance growth and health. Common additives include minerals, rare earth elements, and insect-resistant supplements. For example, adding 0.02% rare earth to the diet can increase daily weight gain by 17.1% over 60 days. These additives not only support growth but also improve overall health and resistance to diseases.
By implementing these strategies, farmers can significantly improve the productivity and profitability of Boer crossbred sheep. With proper attention to nutrition, health, and timing, these animals can thrive and deliver excellent results.
