Thirty two crossbred Suffolk male lambs (4 month old) with average live
body weight 19.75kg were randomly and equally assigned to four experimental
treatments (8 lambs each) to study the effect of dietary addition of fenugreek and
coriandrum sativum on lamb performance. The lamb groups were fed according to
NRC allowances (1989). The four experimental treatments were: T1- concentrate
feed mixture and berseem hay (control ration). T2- ration of (T1) plus fenugreek (F)
·see.O meal (5g I head I day), T3- ration of (T1) plus coriandrum sativum (CS) seed ..
meal (5g I head /day ) and T 4·ration of (T1) plus F and CS (5g J head I day; 1: 1
ratio). The experimental period lasted for 180 days. At the end of the experimental
period four animals from each group were used in digestibility trail; also three animals
from each group were slaughtered at the end of the experiment. The main results were as follow: Dry mater intake was not significantly differed between treatment groups. The OM, OM, CF, EE, and NFE digestibility and total digestible nutrients of T2 was
sig;:ificanUy ( P<0.05) higher than for control diet but insignificantly higher than for T1,
T3 and T4. Digestible crud protein was almost similar among aU treatments. Ruminal
PH value of treated groups were mildly to acidity at zero and 6 hrs. No significant
differences were detected between different groups at zero and 6 hrs post feeding for
ammonia - nitrogen concentrations. Volatile fatty acids concentrations at all limes
were higher for supplemented groups than the control group. Medical plants of the T2 and T3 had higher (P> 0.05) values of serum total
protein, albumin, Globulin, creatinine, GOT and GPTthan values of the control group.
However, blood serum alkaline phosphatase, urea nitrogen ,values and AlG ratio
were lower for T2 (P>0.05) than the comrol. The effect of medical plants on GO, were
highiy significant (P<0.01) and were Significant (P<0.05) on urea nitrogen and GPT.
The effect of sampling time on creatinine, alkaline phosphataes, urea nitrogen, GOT
and GPT were highly significant (P<0.01) and not was significant on protein fractions.
Lambs in treatments T2, T3, and 14 had higher (P control group. The best economical return was achieved by the group fed diet
contained fenugreek followed by Ihe group received diet contained coriandrum
salivum.
