ABSTRACT



The aim of the studies was the influence comparison of the three kinds of blood products: brown and black dried livexes and blood meal, added to sheep forage, on total protein level, energy value, volatile fatty acids (VFA) amount, levels of carbon dioxide and methane in caecal content of the animals. The samples of caecal content were taken from the sheep immediately after slaughtering, i.e. 2,5 hrs after morning feeding. The livex and blood meal were added to the forage in the amount of 2%. During in vivo application of these nonconventional dietary supplements, the significant inhibitory livex (black and brown) effect on methane level in the sum of caecal gases (45,5% increase for black and 33,4% for brown livex, respectively). Energy of caecal content was about 30% higher in sheep fed with black livex. Respective percentage was about 40% and about 20% for the brown livex and blood meal respectively. Percent increase of protein amount was as follows: 17,9% (for black livex), 23,1% (for brown livex) and 14
