In years 1990-1991, laboratory experiments were carried out to estimate values of coefficients of apparent digestibility in two genetic lines of carp fry: a scaly form (HoS) with initial weight of 37 g and a scattered form (HoL) with initial weight of 49 g. Experiments were carried out at the water temperature of 20°C. Two feeding mixtures were tested, viz. S1 and S2 with 19 and 34% of protein. The...
The effect of ß-glucanase and xylanase supplementation of rye feed on the viscosity and microstructure of the chicken digesta was studied. The viscosity of the digesta decreased significantly in both anterior and posterior parts of the small intensine due to the enzyme supplementation. The fluorescence microscopic examinations indicated that the supplemented enzymes had effectively hydrolyzed the...
