Daftar Isi:
- This research was conducted to evaluate rumen microbial protein supply and nitrogen balance in thin tail sheep fed by king grass:concentrate (65:35) with addition of cinnamon (Cinnamomum burmanni ness ex bl.) as the source of cinnamaldehyde. Nine of 16 months old thin tail sheep with body weight of 19 - 23 kg were assigned to receive three dietary treatments 0, 300, and 600 mg/kg DM of cinnamaldehyde in concentrate mixture according to one way completely randomized design. Animal were put in the metabolism cages, fed ad libitum twice a day at 08.00 am and 15.00 pm. The feeding trial was run for one-week collection period, after a couple month of adaptation period. During collection period, samples of feed, refusal feed as well as feces were taken out for dry matter, organic matter, and crude protein analysis. Daily urine collection was done for purine derivatives (PD) analysis including allantoin, uric acid and xanthine-hypoxanthine. The data of total urinary PD excretions were used to estimate microbial nitrogen supply. The result showed, there were no significant differences between allantoin, uric acid, xanthine-hypoxanthine and total PD excretion from sheep fed with control diet and diets contained 300 and 600 mg cinnamaldehyde per kg DM. Estimated rumen microbial nitrogen supply was 2.76 ±0.27, 3.38±0.68 and 4.57±1.80 g/day in sheep, fed control diet and diets containing 300 and 600 mg cinnamaldehyde, respectively. There were no significant differences in those values, even if the values were expressed per gram digested organic matter in the rumen (DOMR). Nitrogen intake and N feces increased significantly by increasing of cinnamaldehyde in the diets, while urinary N remain the same, therefore N balance were increased by the cinnamaldehyde addition. It could be concluded that the addition of Cinnamomum burmanni ness ex bl. as a source of cinnamaldehyde increased protein diet efficiency.
