L-Aspartate (L-Asp), D-aspartate (D-Asp) or their chemical conjugates plays important physiological roles in regulating food intake, plasma metabolites and thermoregulation in animals. However, there are very few studies available in layers and no reports have been found in broilers. Broilers are very important commercial birds for meat production, so effects of L-or D-Asp in broilers would provide new physiological insight of this strain. Therefore, the purpose of this study was to determine the effect of oral administration of L-or D-Asp on feed intake, rectal temperature and some plasma metabolites in broiler chicks. Broiler chicks (5 days old) were orally administered with different doses (0, 3.75, 7.5 and 15 mmol/kg body weight) of L-or D-Asp. At 120 min after administration of L-or D-Asp, the blood was immediately collected through the jugular vein. The rectal temperature of chicks was measured at 30, 60 and 120 min after administration using a digital thermometer with an accuracy of ±0.1℃, by inserting the thermistor probe in the rectum to a depth of 2 cm. A repeated-measures two-way ANOVA was applied for the analysis of feed intake and rectal temperature. Plasma metabolites were statistically analyzed by one-way ANOVA and regression equations. The study showed that oral administration of both L-and D-Asp did not alter feed intake. However, D-Asp, but not L-Asp, dose-dependently decreased the rectal temperature in chicks. It was also found that DAsp increased plasma glucose and decreased triacylglycerol concentrations. The changes in plasma metabolites further indicate that D-Asp treatment modulates the energy metabolism in broiler chicks. In conclusion, D-Asp may be a beneficial nutrient not only for layers but also for broilers, since orally administered D-Asp lowered rectal temperature without reducing feed intake.

Ampas tebu merupakan Iimbah pabrik gula yang banyak ditemukan dan dapat mencemari lingkungan apabila tidak dimanfaatkan. Saat ini belum banyak peternak menggunakan ampas tebu tersebut untuk bahan pakan ternak. Tujuan dari penelitian ini adalah untuk mengetahui mengetahui pengaruh proses ensilase dan penambahan biomas Indigofera terhadap fraksi serat tepung ampas tebu. Penelitian dilakukan secara eksperimen dengan menggunakan Rancangan Acak Lengkap (RAL). Berdasarkan hasil penelitian ini dapat ditarik kesimpulan bahwa penambahan biomasa Indigofera belum mampu menurunkan kandungan neutral detergent fibre (NDF), acid detergent fibre (ADF), dan Acid detergent lignin (ADL) tepung silase ampas tebu.

This research was conducted in May to June, 2016 in Post-Harvest Technology Laboratory of the Faculty of Agriculture and Animal Science State Islamic University of Syarif Kasim Sultan Riau, and Laboratory of Food and Beverage Trade, Cooperatives, Small and Medium Enterprises Services, Pekanbaru City, Riau Province. This study of aims to determine the physical quality the ice cream with the addition of grass jelly leaves gel as a stabilizer in ice cream. The experimental design used in this study was completely randomized design with five treatments and four replications. Parameters obsered were on study treatment is P0 (without grass jelly leaves gel), P1 (0,25% of grass jelly leaves gel), P2 (0,50% of grass jelly leaves gel), P3 (0,75% of grass jelly leaves gel) and P4 (1,00% of grass jelly leaves gel). The parameters observed were melting time, pH and glucose content. The results showed that the addition of grass jelly leaves gel did not significantly affect (P>0.05) melting rate of ice cream, but significantly decreased the pH value of ice cream (P<0.01) and increased glucose concentration of goat milk ice cream (P<0.01). The conclusions of this research that goat milk ice cream stabilized using grass jelly leaves gel at the level of 1,00% produce yield glucose content was 38,91%, the melting rate for 13,45 minutes and 6,10 of pH value
