Abstract

Egg production of quails depends on quality of ration. Nutrient manipulation by chromiun inclusion in ration is a possible way to improve production.  It is known that chromium mineral in form of GTF in blood has a role not only in enhancement of glucose entering cells through improvement of insulin activity but also in metabolism of lipid and synthesis of protein and elimination of heat stress to improve egg production. This study aimed at assessing egg production of quails fed ration containing chromium-yeast.  Sixty-four quails aged 40 days were used. A completely randomized design with 4 treatments and 4 replication was applied in this study. Treatment consisted of commercial ration + Cr 0 ppm (R1), commercial ration + Cr 0.5 ppm (R2), commercial ration + Cr 1 ppm (R3), and commercial ration+ Cr 1.5 ppm (R4). Measurements were taken on feed intake, egg weight, egg mass production, hen day, feed conversion rate, egg index, and egg shell thickness.  Results showed that A ration containing organic chromium as much as 1,5 ppm did not affect feed intake, egg production, egg weight, and eggshell thickness, however lowered feed conversion rate by up to 32.25% from that of control. Supplementation of  0,5 ppm chromium in the ration lowered the value of eggs index in the fourth week. Key Words: Quail, Egg Production, Chromium-Yeast

Abstract

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.

Abstract

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 vitro

Abstract

A study was conducted to evaluate the effect of feeding different levels of rumen undegradable protein (UDP) in concentrate on performance of five breeds of sheep. Namely: Compass Agrinak (CA); Garut Composite breed (KG); Barbados Cross breed (BC); St Croix breed (SC); and Local Garut (GL) breed. Ten heads of sheep were used from each breed, in which each breed was grouped into 5 groups according to their body weight, and each sheep in each group was assigned to one of two treatments diet. The diet treatment consisted of concentrate containing different levels of undegradable protein (UDP). The levels of undegradable protein were 4.5% and 7.5%. Concentrate were formulated in iso nitrogen (CP content 16.7%) and iso energy (ME content 2.5 Mcal/kg). During feeding trial the sheep were kept in individual pen for three months. Study was conducted in randomized complete block design in factorial 5 x 2 arrangement, 5 levels of breeds sheep and 2 levels of UDP content. Results shows that there was no interaction effect of breed and levels UDP on feed consumption, average daily gain and feed conversion. These variables were significantly (P<0.05) affected by breed of sheep. The highest DMI (dry matter intake) was in KG sheep, the highest DMI caused by highest crude protein and gross energy intake, which in turn lead to highest average daily gain (ADG) of this breed. However the ADG of KG was not significantly different from GL. Apparent nutrient digestibility was not affected (P>0.05) by interaction between breed of sheep and UDP levels in the diet except for OM digestibility. While breed of sheep did not affect nutrient digestibility and UDP levels only affected NDF digestibility. From this study, it is concluded that increasing UDP in the diet did not improve growth performance of sheep. At similar quality of feed the growth performance was affected by breed of sheep in which KG and GL sheep had similar average daily gain (86.01 vs 82.38 g/day).

Abstract

Different thawing metods were applied to frozen beef in order for evaluating both the physical and chemical qualities.  The study used a completely randomized design with six treatments as follow:1) fresh beef  as  control, 2)  frozen  beef allowed  at  room temperature (27-300C)  until internaltemperature of beef reached 00C (became unfrozen), 3) Frozen beef thawed at refrigerator temperature, i.e. 8-100C, 4) Frozen beef thawed at running water which its temperature range within 25-280C, 5) Frozen beef thawed by boiling water (1000C), and 6) Frozen beef thawed by hot water (<1000C). Every treatment was made in three replicates. Results of the study repealed that frozen beef thawed by running water, hot water, or boiling water resulted in better physical qualities than the one thawed by refrigerator temperature (P<0.05). All thawing methods did not significantly affect on chemical qualities of the beef (P>0.05). Moreover, all frozen beef showed similar chemical qualities to the fresh beef.

Abstract

Research action of society service project in implementing forages ammoniating technology in increasing sheep performances had been conducted in eight months at Desa Gede Pangrango Kecamatan Kadu Dampit Kabupaten Sukabumi. The project was aim to increase practical ability of sheep farmers in forages ammoniating technology, forages quality, and to anticipate forages supply problems in draft season. Methods to attain the project goal included: education, training, demonstrating, practicing, and feeding ammoniated forages. Afterward, the sheep fed ammoniated forages had been weight monthly for three months. Methods to measure attainment of this goal project included questionnaire based interviewing and field monitoring to sheep farmers, parameters to measure ammoniated forages quality based on physical characteristics of ammoniated forages, whereas sheep responses to ammoniated forages measured by palatability and a three-month live weight gain. Results of the research action concluded that sheep farmers accepted well to introduction of forages ammoniating technology and able to ammoniating forages by themselves. Ammoniated forages-molasses mixes with ratio of 1% urea and 1% molasses of dry basis forages increased live weight gain of sheep 0.87 – 1.44 kg/3 months and higher than the weight gain of sheep fed non-ammoniated forages. Feeding ammoniated forages-molasses mixes increased profitability of sheep farmers as high as 18% (Rp78,354.00) whereas feeding ammoniated cassava peel-molasses mixes generated profit up to 51.44% (Rp222,966.00) higher than feeding non-ammoniated forages. Supporting sheep supply and market assurances will maintain the continuity of feeding of ammoniated forages.
