Abstract

A study of effect of inclusion of calcium-palm fatty acid (Ca-PFA) in the diets on growthperformance and profile of body fatty acid has been conducted for 4 weeks in broiler. A total of 160birds were used in present experiment which was arranged in a Completely Randomized Design with 4treatments and 5 replications (8 birds each). Dietary inclusions of Ca-PFA of 0, 5, 10 and 15% werereflected as R0, R1, R2 and R3, respectively. Results of the experiment showed that growth performancebased on the feed consumption significantly decreased (p<0.05), but there were no significant (p>0.05)effect for final body weight, carcass percentage and carcass composition. The inclusion of Ca-PFA in thediet was not affected the saturated fatty acid (p>0.05), but showed significant effect on unsaturated fattyacid and omega-3 fatty acid (p<0.05). Body fat distribution was not affected by inclusion level of Ca-PFA at a level of 15%. In conclusion, the inclusion of Ca-PFA in the diet until 15% decreased feedconsumption and produced similar growth performance, however it increased unsaturated fatty acid,omega-3 fatty acids and decreased body fat of broiler.

Abstract

The aim of this study was to find out the influence of vitamin-mineral supplementation ondigestibility and rumen fermentation in Bali cattle. The randomized block design with 4 treatments and 4replications were used in the research. In this study was used 16 Bali cattle with body weight around295.31+23.07 kg. Rations used in the treatments were Treatment A (control): rice straw ad libitum pluscommercial feed; Treatment B: Treatment A ration plus 0.2% vitamin-mineral in commercial feed;Treatment C: Treatment A ration plus 0.3% vitamin-mineral in commercial feed, and Treatment D:Treatment A ration plus 0.4% vitamin-mineral in commercial feed. Parameters measured were nutrientdigestibility, rumen metabolites and urinary allantoin. The results showed that supplementation ofvitamin-mineral at 0.2 - 0.4% in commercial feed did not increase the digestibility of dry matter, organicmatter, crude protein and crude fiber, except for dry matter and organic matter digestibilities at 0.2%supplementation (p<0.05). However, the vitamin-mineral supplementation increased concentrations ofpartial VFA and ammonia as well as for methane gas production, except for VFA and ammonia at 0.4%level. Vitamin-mineral supplementation at 0.2-0.4% level did not affected pH value of rumen fluid andurinary allantoin.
