| Abstract |
Twelve lactating Friesian cows in the 3rd and 4th of lactation, weighting 450-500 kg were used after 8 weeks of calving in a complete switch-back design and divided randomly into three similar groups (4 in each). Cows in the first group were fed control ration (RI) consisted of 60% concentrate feed mixture (CFM), 25% berseem hay (BH) and 15% rice straw (RS). While, cows in the second group were fed R2 consisted of 60% CFM, 30% dried artichoke byproduct (DAP) and 10% RS and those of the third group were fed R3 consisted of 60% CFM and 40% artichoke by-product silage (ABS, on DM basis).
The contents 0 f CP, EE, N FE and ash were higher, while OM and CF contents were lower in ensiled than dried artichoke by-product. The contents of CP and NFE were higher, but CF and EE were lower in ensiled artichoke byproduct compared with berseem hay. While, the contents of OM and ash were nearly similar for ensiled artichoke by-product and berseem hay. Ration 3 revealed the low DM content and the higher OM, CP, EE and NFE contents, R2 the higher content of CF, while R1 had the higher DM and ash contents.
Cows fed R3 recorded significantly (P<0.05) the highest digestibility coefficients of DM, OM, CP, EE and NFE and subsequently TDN and D CP values followed by those fed R2, while those fed RI had the lowest values.
However, CF digestibility of cows fed RI and R2 was significantly higher (P<0.05) than R3. Cows fed Rl and R2 recorded significantly (P<0.05) the higher DM intake and the lower DCP intake compared with those fed R3.
While, TDN intake by cows fed R2 and R3 was significantly higher (P<0.05) than those fed RI. Feeding R2 and R3 containing artichoke by-product as dried
