Determination of technological parameters of the granulation of mixed fodders for young rabbits and the evaluation of their effectiveness
The composition of all-mashes for young rabbits when granulating liquid grain molasses was introduced as a binder. To find the optimal parameters of the process of granulation of all-mashes containing grain molasses, studies were conducted on an experimental setup. To improve the nutritional value and digestibility of all-mashes in the recipes were introduced probiotic feed additive "Sportermin", "Prostor" sorbents "Carbitoks" and "Fungistat-GPK". To find the optimal parameters of the process of granulation of all - mashes, studies were conducted on an experimental setup,including a press granulator, using the method of statistical planning of a multifactorial experiment. Mathematical models of the process of granulation of mixed fodders with grain molasses, establishing the dependence of granularity and energy consumption of the selected factors: as a result of granulation of loose feed under optimal conditions of good quality granules. As a result of a comprehensive evaluation of the quality of complete granulated all-mashwe found that the resulting all-mash, investigated by physico-chemical, organoleptic, microbiological and safety indices, meet the requirements for all-mash for feeding young rabbits. It is established that the rabbits of the experimental groups receiving a balanced, prepared in accordance with the detailed rules of the diet arebetter digested nutrients of the feed compared with the control peers, which further had a positive impact on the performance of their meat productivity. Enrichment of mixed fodders for feeding livestock calves rabbits probiotic microorganisms comprising the probiotic used preparations has a positive influence on meat efficiency, preservation and increase of biological value of rabbit meat.The developed recipes of complete feed with the introduction of feed probiotic additives will increase their digestibility by 10-15%.
