Testing of the technology of cavitation treatment of sunflower oil sludge to increase the digestibility of feed for calf bulls

Abstract

Abstract The article presents the results of research to assess the effectiveness of the developed technology for processing sunflower oil sludge, using cavitation, to increase the digestibility of feed and metabolism of calf bull. When introduced into the diet of sunflower oil sludge in the native form + 10 % (group II). It was established that the highest indices of digestibility of the majority of nutrients were in cavitated fuse. In particular, fodder enriched with fuse contributed to greater energy consumption and its more productive use. Digestible energy was higher by 7.1 % (P≤0.05) and 9 % (P≤0.05) in groups I and II, respectively. Metabolic energy exceeded the control level by 5.7 and 7.1 MJ. The inclusion of fuse in the compound feed increased nitrogen digestion by 4.5 % (P≤0.05) in group I and by 5.8 % (P≤0.01) in group II. At the same time, higher indicators are achieved when feeding with fuse treated by the cavitation method.
