Effects of three slow-release urea inclusions in rice straw-based diets on yearling Bali bull performances

The effects of slow-release zinc-urea complexes (ZnU), urea-impregnated zeolite (UZ) and zinc-ureaimpregnated zeolite (ZnUZ) on the performance of yearling Bali bulls were assessed using 20 Bali bulls (145.3 ± 2.5 kg bodyweight (BW)), which were allocated to five treatments and four replications in a completely randomized design. The treatments were: Diets supplemented with no urea (NU) and with urea (U), ZnU, UZ and ZnUZ. The results of the in vivo study revealed that both ZnU and UZ might replace urea effectively by increasing feed intake. Moreover, substituting urea with ZnU, UZ or ZnUZ increased crude protein total tract apparent digestibility whereas ZnU or UZ replacing urea, improved fibre total tract apparent digestibility. Furthermore, inclusion of UZ in the diet improved live weight gain and feed efficiency in Bali bulls above that of the U and NU diets. Thus, the inclusion of ZnUZ in rice straw-based diets showed slow-release urea had positive impacts on feed intake and nutrient digestibility, and increased the efficiency of feed utilization in Bali bulls.Keywords: Apparent digestibility, feed intake, urea-impregnated zeolite, zin

In vitro slow-release urea contained in rice straw-based diets to increase efficiency of rumen microbial protein synthesis

Effect of slow-release urea on efficiency of rumen microbial protein synthesis (EMPS) was examined using an in vitro technique. The objective of this experiment was to reveal the in vitro slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea in relation to EMPS observed in different incubation time. The experimental design employed was randomized block design with 4 x 3 factorial plus a control treatment, and conducted in two replications. Factors were various urea sources (urea, zinc-urea, zeolites-urea, and zeolites-zinc-urea) and molasses concentrations (0%, 6%, and 12%) in rice straw-based diets. The control treatment was the rice straw-based diets containing neither urea nor molasses. Diets consisting of 45% rice straw and 55% concentrates (DM basis) were formulated to have similar N and TDN levels. Responses of parameters measured were subjected to MANOVA using the GLM procedure of SPSS 16.00 and differences among mean values, if applicable, were examined using HSD-test. Orthogonal comparisons were used to determine the effects of the control treatment vs. various urea sources. Results indicated that treatment of UZ combined with 6% of molasses showed the highest microbial biomass production (2.71 mg/l) at 24 hours fermentation period with its peak production estimation (3.2 mg/l) reached at 33.5 hours of fermentation period. Moreover, UZ treatment resulted in the highest microbial protein synthesis (1,381.45 ± 77.1 mg/l) at 24 hours fermentation period with its peak microbial protein synthesis estimation (1,756.04 mg/l) reached at 33.7 hours of fermentation period. The highest EMPS (25.98 ± 1.21 mg/100 mg OMD) was achieved when ration contained 6% of molasses. Key words: Slow-Release Urea, Microbial Protein Synthesis, Microbial Biomass, In vitr

In vitro slow-release urea characteristics under different molasses levels contained in rice straw based diets

Slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea were examined using in vitro techniques. The objective of this experiment was to study the in vitro slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea under different molasses concentrations in relation to the ruminal fermentative changes observed in different incubation time. The experimental design employed was randomized block design with a 4 x 3 factorial arrangement plus a control treatment, and conducted in two replications. Factors were various urea sources (urea, zinc-urea, zeolites-urea, and zeolites-zinc-urea) and molasses concentrations (0%, 6%, and 12%) in rice straw based diets. The control treatment was rice straw based diet containing neither urea nor molasses. Diets consisted of 45% rice straw and 55% concentrates (DM basis) were formulated to have similar N and TDN levels. Responses of parameters measured were subjected to MANOVA using the GLM procedure of SPSS 16.00 and differences among mean values, if applicable, were examined using HSD-test. Orthogonal comparisons were used to determine the effects of control treatment vs. various urea sources following significance for the two-factor ANOVA model. Results indicated that zinc-urea, zeolites-urea, and zeolites-zinc-urea under different molasses concentrations contained in rice straw based diets decreased ruminal ammonia up to 48 hours incubation, controlled total VFA level and pH values revealed from lower NH3:VFA ratio, and improved both in vitro dry matter and organic matter degradabilities. The best impact of the in vitro slow-release urea characteristics of zinc-urea, zeolites-urea, and zeolites-zinc-urea on the ruminal fermentative changes (NH3, VFA, pH, DMD, OMD) was well attributed to the diets contained 6% molasses.
