The objective of this work was to determine the effect of inclusion different levels of broccoli wastes in lamb rations on their productive performance, nutrient digestibility, feeding value, physiological and hematological parameters, rumen fermentation and also the economical efficiency.Twenty four growing male crossbred lambs (50% Finland+50% Rahmani) aged 3 months after weaning with averaged live body weight (LBW) 16.80 ±0.82 kg were randomly assigned into three similar groups (8 lambs each) using randomized complete block design. Three experimental diets were formulated as the first group was served as (control) (R0) and fed the concentrate feed mixture (CFM) according to recommendations of NRC (1989) plus the rouphage portion that consisted of 50% berssem hay and 50% wheat straw, while the diets of the second (R1) and third (R2) groups were including broccoli waste at 20 or 40% levels in replacing to berssem hay, respectively. Results of digestibility coefficients, showed no significant effect due to experimental treatments was noticed for digestion coefficients of DM, OM, CF and EE. The digestibility of CP and NFE and subsequently feeding values in terms of TDN and DCP were almostly significant higher with tested rations than control one. Final live body weight and daily weight gain were increased (P |
