Abstract

Ruminants can achieve high productivity when the diet includes concentrates; however these are often expensive due to competition with humans and mono-gastric animals. This experiment was conducted to determine the effect of partial inclusion of Albizia saman pods (ASP) in a Commercial Concentrate (CC) on the performances of dairy cows. Twelve cross-bred Holstein Friesian cows (472±13 kg) in the 12th week of lactation were randomly allocated into four treatment groups with three replicates accoding to the completely randomized design. The four treatments were control diet-CD [35% urea-treated-rice-straw (URS; 79g crude protein (CP)/ kg dry matter (DM)) and 65% CC (contained 40% cottonseed cake, 35% broken chickpea and 25% chickpea husk on an as fed basis and provided 200g CP/kg DM)], D1[35% URS + 60% CC + 5% ASP (189g CP/kg DM)], D2 (35% URS +55% CC + 10% ASP) and D3 (35% URS + 50% CC + 15% ASP). Cows were fed treatments for 60 days. Dry matter intake was significantly higher (p<0.05) for cows in the D3 treatment compared with the other three treatments, however there were no significant differences in the DM digestibility of treatments. Nitrogen intake and faecal-nitrogen of cows offered the D3 treatment were significantly higher (p<0.05) than those of cows offered the other three treatments. In contrast urine-nitrogen and nitrogen utilization were not significantly different among the treatments. The average milk yield (4% fat-corrected-milk) increased as the percentage of ASP was increased in the diets, however the composition of milk did not differ significantly between treatments. The costs of TDN/kg and per kg of milk was highest for the CD treatment and the lowest was found in D3 treatment (p<0.05). These results suggest that Albizia saman pods could be replace up to 15% of the commercial concentrate fed to lactating Holstein Friesian cross-bred cows without detrimental effects.
