The purpose of the work is to study the bioenergy potential of modern fodder resources for highly productive livestock.
The analysis of natural and climatic conditions for previous years and years of research is carried out. The regularities of their changes are established.
Modern priority feed resources have been identified to ensure stable balanced feeding of highly productive livestock. Technologies of preparation of canned fodder from modern fodder resources are estimated.
Installed:
- the highest coefficient of preservation in the procurement of fodder from sainfoin was obtained in the procurement of haylage, both with the use of preservative and without it, with a dry matter content of 35%. The lowest rate was when harvesting hay. A similar trend is observed when comparing the data of short-term feed prepared from alfalfa, a four-component mixture of perennial grasses and oat-oat mixture, except for alfalfa haylage with a content of 25% DM.
- the best way to harvest fodder from perennial grasses, their mixtures, and annual grasses - is to harvest haylage with a dry matter content of 35%, subject to the use of preservatives.
Received:
- the use of compatible crops of corn and sorghum increases the harvest of green mass by 65.4%, dry matter - 41.5%, DOE - 27.0%, crude protein - 24.5%;
- the best results were obtained when co-growing sorghum with maize hybrids with a higher FAO, in particular, from 270 to 390;
- the lowest energy costs for the production of 1 quintal of green mass, dry matter, crude protein were on the options of compatible crops of corn and sorghum, compared with crops of corn.
An objective indicator has been developed and proposed for use for a comprehensive assessment and comparison of different methods of bulk feed preparation, which is calculated according to the formulas of the coefficient of energy and protein efficiency of feed procurement technologies.
