Effect of the amount of zeolite in diets with urea on the digestibility of nutrients and nitrogen balance in fattening young bulls

, : Effect of the amount of zeolite in diets with urea on the digestibility of nutrients and nitrogen balance in fattening young bulls. Zhivotnov"dni Nauki 21(7): 64-70

In 4 series of balance experiments 3 Sofia Brown bulls, weighing 220 to 300 kg, were given complete mixed feeds with 50% roughage and 2.4% urea (50% of dietary crude protein) without or with zeolite 1, 3, 5 or 10% to provide 2, 6, 10 or 20% of dietary concentrates, respectively. With 5 or 10% zeolite digestibility of DM, fats and ash decreased significantly compared with that in controls. With 3% zeolite differences were significant only for DM.
