Abstract | The effect of immission dust on fermentation processes in rumen of young bulls of Black Pied breed, on the digestibility of nutrients, and on the nitrogen and magnesium balance were studied. The possibility of eliminating the negative impact of magnesium by adding fat from rendering plant and rape-seed oil was also investigated. Four feed rations (control, with fly dust and fat, with fly dust and rape-seed oil) were tested. The magnesium intake was five times higher than the animals required. The basic fermentation parameters in proventriculi (pH, N-NH3, VFA) did not change significantly during the day. The concentration of plasmatic and soluble magnesium rose significantly in rumen fluid. Young bulls took an extra 41 g of magnesium daily, out of which 32.37 g were excreted in faeces. After the addition of fat from rendering plant and rape-seed oil, the amount of excreted magnesium decreased to 29.63 g and 28.69 g respectively. Feeding of fly dust decreased digestibility of fibre, crude protein, ash and dry matter. Addition of the fat raised the digestibility of crude protein, fat, phosphorus and magnesium extract. Significantly more nitrogen was retained in the organism of young bulls |
