This study was conducted on 30 Damascus female dairy goats to investigate the effect of dry guava leaf
supplementation on milk yield, milk composition, immune response, and economic efficiency under a grazing or
confinement management system. Experimental goats were divided into two groups (15 goats/group). The first
group was allowed to graze Egyptian clover while the second group was kept in clean and hygienic pens. Each
management group was further divided into three sub-groups (5 goats/sub-group). The first sub-group was fed
on the basal diets of the farm according to NRC (2007), the second sub-group received the basal diet
supplemented with 1% dry guava leaves, and the third sub-group received the basal diets supplemented with 2%
dry guava leaves. Daily and overall milk yield were recorded throughout the 12 week experimental period. Milk
samples were collected weekly in the morning from each goat and stored at 5º C until analysis. Blood Samples
were collected individually from each goat at the end of the experimental period for analysis. Results showed
that grazing goats supplemented with 2% dry guava leaves had significantly higher (P
