Sažetak
The aim of this study was to investigate the effects of Na-butyrate and
Yucca schidigera extract treatment on skeletal development of pigs. The study was conducted from the 14th until the 56th day of postnatal life. Piglets were randomly assigned to control group fed on a standard diet supplemented with a coated blend of organic acids (fumaric, malic and citric - 1.5 kg/t feed), and an experimental group fed on a similar diet with the addition of coated Na-butyrate (900g/t feed) and extract of Yucca schidigera (75g/t feed). At age of the 28th, 35th and 56th days of life the piglets were slaughtered and the humera were isolated for further analyses. The bone formation and quality were measured based on weight, length, bone mineral content (BMC), bone mineral density (BMD), physical (ultimate strength, maximum elastic strength) and geometrical parameters.
The bone weight and geometrical parameters such as cross-sectional area, second moment of inertia, mean relative wall thickness were significantly increased in experimental 56 d old piglets. Furthermore, experimental diet induced significantly higher BMC and BMD, and improved the mechanical endurance of bones in terms of the moments of maximum elastic strength and maximum strength. It is concluded that early postnatal treatment of piglets with Na-butyrate and extract of Yucca schidigera positively affects the development and function of the bones during growth.
