Résumé
A study was conducted to evaluate the effect of feeding different levels of dried Ziziphusspinachristi leaf on feed intake and live weight gain of local male goats at Kallu District, South Wollo zone, north east Ethiopia from November 2015 to February 2016. Twenty-five yearling growing intact local goats, with average body weight of 20.68± 0.72 kg were arranged in randomized complete block design (RCBD) with five treatments and five replications. Different levels Ziziphus-spinachristi leaf were supplemented in various treatment groups i.e. T1 (grass hay only) being control group, T2 (75% pasture grass hay, 25% Ziziphus), T3 (50% grass hay, 50% Ziziphus), T4 (25% grass hay, 75% Ziziphus) and T5 (100% Ziziphus-spina-christi).The experiment was conducted for 90 day of feeding trial during those days feed intake was measured daily and BW change was measured at 7 days (every week)interval throughout the experiment. There was significant (P< 0.05) increase in total dry matter intake of goats fed on supplemented diet than the control group fed on grass hay only. Mixing of the pasture grass hay diet significantly (P<0.05) improved animals feed in take from 440 to 592g/head/day at the minimum proportion of, 25% Ziziphus mixture. However, there was no significant difference (P>0.05)in feed intake among the supplemented groups (T2-T5) as the proportion of Ziziphus-spinachristi increased. Goats in the control group and in 25% Ziziphus treatment diet gained31.4 and 46.7 g , which was not significantly different. The highest (P< 0.05) average daily body weight was gained in goats supplemented with highest level (100 %) of Ziziphus group. There was significantly (P<0.05) increasing trend of body weight gain was observed at increasing level of different proportion of leaves were given as at 50% (90g/day), 75 %( 110g/day) and 100 % (190g/day). Feed conversion ratio significantly (P<0.05) increased with increased inclusion level ofZiziphus- spinachristi leaf. Goats under supplemented treatment diets had significantly higher (P < 0.05) feed conversion ratio than the control groups. Generally, the results of the current study showed that supplementation of goats with above 50% level of dried Ziziphus-spinachristi leaf in their diet significantly increased feed intake and body weight gain by improving feed conversion efficiency of goats.Ziziphus-spinachristi can be used as a potential feed to goats feed which is usually available in arid and semi-arid rangeland of the study area.
