摘要

在RF农工综合体发展的现代条件下,只有随着高档植物蛋白产量的增加,畜牧业向工业基础的转移才有可能。在植物生长发育的各个阶段,纯玉米地上质量的青贮不能提供饲料单元中符合动物技术要求的营养成分含量。因此,在玉米青贮料制备过程中,应在成品饲料中添加豆科植物的青质量,以优化成品饲料的糖蛋白比。豆科成分的选择应考虑以下主要标准:与玉米的生长季节吻合,对土壤和气候资源和日照条件的态度相同,青贮期间豆科成分可消化蛋白质、干物质、淀粉和交换能的高供应。研究结果表明,黄羽扇豆和黄羽扇豆的联合青贮适宜于玉米处于蜡熟期,黄羽扇豆处于亮豆期,黄羽扇豆的成分比为55:45%。在这种情况下,在可靠的饲料供应下,1个饲料单位的成品青贮可消化蛋白质含量为100.2 g,同时含有不可替代(36.0 g)和关键(7.2 g)氨基酸。

Eligibility criteria for joint ensilage of maize and yellow lupine on poorly productive lands of the Upper Volga region
In the modern conditions of RF agro-industrial complex development, the transfer of animal husbandry to an industrial basis is possible only with high-grade vegetable protein production increase. Silage of the aboveground mass of pure corn during all phases of plant growth and development does not provide the content of nutrients in the feed unit according to the zootechnical requirements. Therefore, to optimize the finished feed in terms of the carbohydrate-protein ratio, green mass of legumes should be added to its composition during the preparation of silage from corn. The selection of the legume component should be carried out taking into account the following main criteria: coincidence with corn by the growing season duration, the same attitude to soil and climatic resources and insolation conditions, high provision of the legume component with digestible protein, dry matter, starch and exchange energy during the ensiling period. It has been established that the joint ensiling of corn with yellow lupine is expedient when the corn is in waxy ripeness, and the lupine is in the phase of shiny beans with the component ratio of 55:45%. In this case, the content of digestible protein in 1 feed unit of finished silage is 100.2 g at reliable feed supply with both irreplaceable (36.0 g) and critical (7.2 g) amino acids.
