Development of technological approaches to the process of granulation of feed for young rabbits

The paper considers technological approaches to the process of granulation in the production of complete feed. As the purpose of the work carried out were: justification of technological modes of process of granulation of compound feeds for young rabbits developed according to the optimized recipes, also an assessment of quality of the received compound feeds. As the main raw materials in the production of granular feed used cereals, wheat bran, cake and sunflower meal, herbal flour from alfalfa, as well as premix KVP P90-1 / K. To increase the nutritional value and digestibility of compound feeds, enriching additives were introduced into the recipes: probiotic complexes “Sporothermin”, “Prostor”, sorbent “Fungistat-GPK”, as well as feed molasses obtained on the basis of oat grain. The process of granulation of compound feeds with the use of the method of statistical planning of a multifactor experiment using a granulation line including a press granulator is investigated. The dependence of granularity and energy consumption on the selected factors: product feed rate, steam consumption, air consumption and the gap between the roll and the matrix is established. As a result of solving the optimization problem, the optimal values of the input parameters are established, which allow to obtain high-quality feed. As a result of a comprehensive assessment of the quality of full-grain granular feed, it was established that the obtained compound feeds met the requirements for compound feeds for young rabbits. The obtained results showed that the developed recipes of complete feed with the introduction of feed probiotic additives will increase the productivity and safety of young rabbits 10-15% and can be used as feed rations in industrial complexes of the rabbit industry.
