Abstract

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<0.05) milk yield, immune response, and economic efficiency compared to the other groups. Additionally, grazing goats supplemented with 2% dry guava leaves had blood metabolite levels within the normal range compared to the other groups.  It was concluded that supplementing grazing goats with 2% dry guava leaves improved milk yield, immune response, and economic efficiency without negative effects on blood metabolites
