The invention belongs to the technical field of Xinjiang brown cattle feeding, and discloses a feed for Xinjiang brown cattle to produce high-grade beef and a preparation method. The feed consists of roughage, energy and protein feed, premix and other additives. The present invention uses white distiller's grains, corn meal, soybean meal and hybrid Pennisetum as main feed raw materials, and is matched with green feed additives (yeast culture) to improve feed digestibility, change rumen hydrogenation mode and intramuscular fat deposition mode, and reduce Xinjiang brown cattle. Feed costs and increased production of premium beef. Through the application of the feed formula of the invention, the feed conversion rate of Xinjiang brown cattle is increased by 8.3%-13.7%, the average daily weight gain can reach 1.0-1.1kg/d, the slaughter rate can reach 54.6%-57.8%, and the eye muscle area can reach 87.5‑89.2cm 2 , the marbling grade of the longissimus dorsi muscle can reach 3.1‑3.5. |
