Abstract

Spreading zeolites on litter floor of broiler house at rate of 5.0 kg/m2 increased broiler carcass percentages up to 5.41 percents. Effect of zeolites-spread litters on broiler carcass and non-carcaSs components under different floor spaces had been performed in five weeks. As many as 324 chicks of a day-old Hubbard strain were fed with rations contained 3,000 -3,100 Kcal/I<g ME and 21 %crude protein during starter period and fed with the ration contained 20% crude protein duringfinisher period. The chicks were allocated to three different floor spaces (10, 12, and 14 heads/m2) and three different zeolites-spread litters (0.0, 2.5, and 5.0 kg zeolites/m2) under completely randomized design with factor 3 x 3 and 3 replications. Parameters concerned of present research including percentages of both carcasses and non-carcass components were analyzed with analysis of variance (ANOV A) and least .significant different.Results of the preseqt research showed that there was no interaction effect between floor spaces and zeolites-spread litters on all parameters concerned. Floor spaces affected the percentages of gizzard, kidney, and spleen significantly (p<O.05) but neither carcass nor abdominal fat percentage was af.fectedby the floor space. The zeolites-spread litters only affected significantly (P<O.05) on carcass percentage. Spreading zeolites at rates of5.0 kg/m2 on litter floor resulted in the highest carcass percentage (p<O.05) while rates of 25 kg/m2 resulted the same carcass pen:entage as the rates of 0.0 kg/m2. It was concluded that spreading zeolites at rates of 5.0 kg/m2 on litter floor under different floor spaces increased can:ass percentages up to 5.41 percents.

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

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

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.
