Abstract

Context

The rising demand for animal protein has intensified forage shortages and restricted pasture availability, underscoring the critical need for effective dual-purpose animal feeds.

Objective

This study aims to evaluate the potential of vegetative soybeans as animal feed by assessing their nutritional value and productivity. Specifically, it explores the feasibility of using late-maturing soybean varieties, adapted to low latitudes, as forage in high-latitude regions and examines the impact of different planting dates on their growth and effectiveness during limited growing seasons.

Methods

To achieve these objectives, a series of field and controlled experiments were conducted. The first experiment assessed 418 mid-maturing soybean varieties from the Huang-Huai-Hai Basin in China for their nutritional value as forage during 2020 and 2021. The second experiment tested late-maturing and photoperiod-sensitive soybean varieties, including "ZGDD" and the methionine-enhanced material "Ox-CGS," under tropical conditions with extended daylight. The third experiment evaluated forage soybeans sown on June 19th, July 14th, and August 8th, 2022, to determine their yield and protein content.

Results

Results showed that the first experiment yielded an average protein content of 24.7 %, ether extract content of 1.9 %, neutral detergent fiber content of 41.9 %, and acid detergent fiber content of 27.3 %, with a relative feeding value of 153, surpassing local standards for high-quality leguminous forage. The second experiment demonstrated that extended daylight increased crude protein yield by 3.7 times compared to Chinese soybean seed yields, and "Ox-CGS" showed a 24.2 % increase in methionine content. The third experiment revealed that forage soybeans achieved a crude protein yield of 0.95 t/ha within 60 days, exceeding the 2022 average of 0.68 t/ha for seed soybeans in China.

Conclusions

The findings indicate that photoperiod-sensitive soybeans can be effectively used as forage over extended periods, utilizing artificial lighting or cultivation in higher latitudes, and that short growth cycles enhance crude protein accumulation.

Implications or significance

This research highlights the potential of soybeans to alleviate forage shortages, improve land use efficiency, and contribute to food security and agricultural development, especially on marginal lands and in regions with limited growing seasons.

评估各种大豆品种的饲料质量和高产栽培技术
背景对动物蛋白质的需求不断增长,加剧了饲草的短缺,限制了牧草的供应,突出了对有效的两用动物饲料的迫切需要。具体来说,它探讨了在高纬度地区使用适应低纬度地区的晚熟大豆品种作为饲料的可行性,并研究了在有限的生长季节中不同的种植日期对其生长和有效性的影响。第一个实验评估了中国黄淮海流域 418 个中熟大豆品种在 2020 年和 2021 年作为饲料的营养价值。第二项实验在热带长日照条件下测试了晚熟和对光周期敏感的大豆品种,包括 "ZGDD "和蛋氨酸增强材料 "Ox-CGS"。第三项实验对 2022 年 6 月 19 日、7 月 14 日和 8 月 8 日播种的饲用大豆进行了评估,以确定其产量和蛋白质含量。结果结果表明,第一项实验的平均蛋白质含量为 24.7%,醚提取物含量为 1.9%,中性洗涤纤维含量为 41.9%,酸性洗涤纤维含量为 27.3%,相对饲用价值为 153,超过了当地优质豆科饲草的标准。第二项实验表明,延长日照与中国大豆种子产量相比,粗蛋白产量提高了 3.7 倍,"Ox-CGS "蛋氨酸含量提高了 24.2%。结论研究结果表明,利用人工光照或在高纬度地区栽培,对光周期敏感的大豆可长期有效地用作饲料,而且短生长周期可提高粗蛋白积累。影响或意义这项研究强调了大豆在缓解饲草短缺、提高土地利用效率以及促进粮食安全和农业发展方面的潜力,尤其是在贫瘠土地和生长季节有限的地区。
