Effect of using Prosopis juliflora pods on Performance of Tali lactating goats

The aim of this study was to examine use of Prosopis julifora pods (PJP) in lactating goats (twenty lactating Tali goats with body weight mean of 34±2.5 kg) diet. Goats were divided in two groups of ten heads) One group with control diet and the other group with Prosopis julifora) and fed for 12 weeks. Diets were prepared based on goats’ requirements from both forage and concentrate with equal proportion. PJP rate in total experimental diet was 19.25%. Animals were weighed individually the beginning of the trial and every two weeks until the end of period. Their weight changes were calculated. Also, their weekly milk production rate and milk compositions were determined. The average daily milk yield and milk fat percent in fed goats with control diet and PJP diet was 550 and 570g, and 3.24 and 2.39%, respectively that weren’t statistically different. Milk compositions (fat, protein, ash, solid material and solid material without fat) weren’t affected by the diet. The body weight during of experimental period and also, between two groups was not significant different statistically. Total cost of feed and milk production of fed goats with 20% PJP diet was cheaper than control group. Therefore, PJP can be used as a feedstuff up to 20 % of lactating goats’ diet and reduce nutrition cost.
