The Need for High-energy and High-protein Maize in China
The shortage of energy and protein feedstuffs is severe in China. Based on present numbers, if all livestock were provided with compound feeds, the amount of compound feeds would reach 280 million tons per year. Assuming the amount of maize in compound feeds as 50％, and soybean meal makes up 15％, in 10 years hence the shortages for maize and soybean meal will be 40～60 and 12.0～14.4 million tons, respectively, per year. At present, 60％～70％ of livestock are not raised on compound feeds, rather agricultural by-products and green forages with low energy and low quality protein are most commonly used. As a result, the contents of energy, protein and lysine in feeds are relatively low, and livestock do not reach their full growth potential. The cultivation of maize varieties with high energy, protein and lysine contents would make a very significant impact on Chinese an animal husbandry.
