This research work was carried out to investigate the effect of adding Egyptian
Chufa tubers in goats diets on nutrients digestibility, some rumen and blood
parameters and growth performance of Zaraibi goats kids. Eighteen kids (average
21.3±0.45 kg live weight) were divided into 3 groups (6 kids each). Animals in groups
G1, G2 and G3 received 0, 5 and 10 g Chufa tubers /head/day, respectively in their
diets. In addition, 9 Zaraibi bucks averaging 51.0 kg body weight were used in three
digestion trails. The obtained results showed that the digestion coefficients of all
nutrients as well as the feeding values (TDN and DCP %) were significantly improved
(P<0.05) as a result of adding Chufa tubers. Ruminal NH3-N concentration was
tended to decrease with increasing level of Chufa tubers. But, ruminal total VFA’s
concentration was increased with increasing level of Chufa tubers. Molar proportion of
ruminal VFA’s showed higher acetate (P<0.05) and propionate concentration but
lower butyrate with the two treatment groups (G2 and G3) compared with G1. Daily
body gain recorded the highest (P<0.05) value (90.22g) with G3 followed by G2
(84.67g) and lastly G1 (76.07 g/head/day). The best feed conversion efficiency, based
on DM, TDN and DCP was 8.51, 5.91 and 0.743, respectively with G3 in comparison
with the other groups. The feed economic efficiency was tended to be increased with
increasing level of Chufa tubers in goats diets.
