-Abstract
لإhis study aimed to determined effect of guava by-product (GBP) substitution at level 20% of concentrate feed mixtures with or without commercial probiotic (Enviva®PRO) on the performance of growing goat kids. Twenty-four growing Zaraibi male kids weighted 15 kg body weight in average and 7 months old; assigned to three groups (8 in each). Feeding trial lasted for 90 days. Animals were fed clover hay plus CFM (R1), CFM including 20% GBP (R2) or supplemented with probiotic, 5g/h/day (R3). Results showed insignificant differences in most nutrients and fiber fractions digestibilities and TDN values among treatments. Ruminal pH and TVFẢs values did not differ significantly among treatments. While, ruminal NH3-N concentrations were significantly (p<0.05) higher with R2 and R3 compared to R1. Results indicated that neither GBP nor probiotic had an adverse impact on goats health which all blood parameters were within the normal range. There were no significant differences among treatments in total and average daily gain. Both R2 and R3 had lower total DM and TDN intake compared to R1. Meanwhile R3 group had the best feed conversion and the highest economical efficiency. It could be concluded that guava by-product (GBP) at level 20% of CFM and probiotic supplementation (5g/h/d) in growing kids goats rations had no adverse effects on productive performance with enhancing in economical efficiency.
