Abstract

This research was carried out to examine the chicory forage yields on different regrowth which were intercropped with Pennisetum purpureum cv. Mott (dwarf elephant grass) on different regrowth due to various harvest age. The research was conducted in the Laboratory of Forage and Pasture, Faculty of Animal Science UGM for 7 months, with a split-plot design and analyzed by Duncan with a total of 9 plots and an area of 2.5x2.5 m2 for each plot. The main plot was the harvest age treatment (30, 45, and 60 days) and the subplot was the regrowth (first and second). In the first stage, as many as 9 cuttings of dwarf elephant grass in one plot were planted with a spacing of 1x1 m2 until the plant height reaches 10 to 15 cm, then the chicory seeds were spread among the dwarf elephant grass plants with the sand mixture. The results showed the harvest age had a significant effect (P<0.05) on chicory's plant height, fresh forage yield, dry matter content, dry matter digestibility, and organic matter digestibility. The 30 to 45 days harvest age performed a higher fresh production more than the 45 days to 60 days harvest age. The 60 days harvest age and second regrowth yielded the highest mixed fresh production compared to the other harvest ages, namely from 12.50 ton/ha to 25.26 ton/ha. Based on the research results showed that the older the harvest age (60 days) increased the biomass of plant production but decreased the plant digestibility. The second regrowth was able to produce higher than the first regrowth, but there was no significant effect on the dry matter content and forage digestibility.

Abstract

This study was conducted to obtain xylanolytic mutants that have higher xylanase activity than their wildtype counterparts. A mutant with the best xylanolytic activity was selected and identified based on its 16S rRNA sequence. Its optimum growth condition was also characterized and its phylogenetic relations to other xylanolytic bacteria were analzsed. Wild type xylanolytic alkalophlic bacteria were grown in medium containing xylan as a substrate. Mutation was performed using ethidium bromide (EtBr) or ethyl methanesulfonate (EMS) atconcentrations 50, 100, and 150 mg mL-1 and times of exposure 30, 60, 90, and 120 min for each treatment. Twenty two mutants were obtained from EtBr and 24 mutants from EMS mutageneses. The mutants were analyzed for their capability to secrete xylanase into xylan medium containing xylose or glucose or glycerol. Growth optimizations of the mutant were done in media with pH range 6-11 and temperature range 30 to 60 °C. Mutant number 19, which was obtained by treatment using 50 mg mL-1 EMS for 120 min, had the highest xylanase activity (15.057 U g-1). This activity was obtained at optimum growth conditions: pH 9.5 and temperature 55 °C. Chromosomal DNA of this mutant was extracted and amplified by PCR using 16S rRNA gene specific primers. The amplified fragments were sequenced by dideoxynucleotide chain terminator method. The phylogenetic analysis based on 16S rRNA gene sequence showed that mutant 19 was closed to an anaerobic xylanase producing bacteria.

Abstract

Red beetroot is rich in phenolic acids and betalain as natural food-coloring agents. Freeze-dried red beetroot that ground into powder can be used as a source of natural coloring to substitute the use of synthetic food color additives as well as filler to substitute tapioca. This study evaluates the function of red beetroot powder not only as filler but also as coloring agent on chicken sausage. Furthermore, its effects as filler (tapioca and beetroot) were also observed on the physical and sensory characteristics of the produced chicken sausage. The substitution of tapioca flour and beetroot powder in this study were 18:0, 17:1, 16:2, and 15:3 (%:%). Each treatment was consisted of three replications. The examined physical properties include pH, water-holding capacity (WHC) and sensory properties. The study found that WHC, color, texture profile and sensory properties were influenced by the increasing level of beetroot flour ratio, while different ratios had no effect on the pH. Chicken sausages made with higher ratio of beetroot flour had good acceptability on flavor and color. The conclusions of this study were substitution tapioca with 2% beetroot powder influenced physical quality (water holding capacity and tenderness) and sensory (color and flavor) of chicken sausage.

Abstract

This study investigated the effect of feeding atung (Parinarium glaberrimum Hassk.) seed meal on growth performance and haematology profile in broiler chickens. A total of 140 one-day-old male New Lohmann broiler chicks were randomly assigned to five treatment groups with four replicates and seven birds in each replicate pen. The dietary treatments consisted of feeding the same corn-soybean meal as the basal diet with atung seed powder inclusions at levels of 0, 0.5, 1.0, 2.0, and 4.0%, respectively. The data were statistically analyzed using One-way with five treatments and four replications and continued with Duncan's New Multiple Range Test for data with a significant difference. Results showed that feed intake increased (p<0.05) in broiler chickens fed diets with 0.5 and 1% atung seed powder. At the same time, the inclusion of atung seed powder had no effect on final body weight, weight gain, and FCR. Inclusion of 1 and 2% atung seed powder significantly increased leucocyte counts, as well as the PCV value trend increased with the inclusion of atung seed powder. It can be concluded that atung seed powder additives can be supplemented in broiler chickens feed at doses 1% by improving feed intake and some haematological profiles.

Abstract

The glass house experiment involving compost tea and harvest age was conducted to investigate the effect of giving compost tea (cricket and rabbit feces) and harvesting age on productivity, nutrient content, and in vitro digestibility value of Cichorium intybus. Compost tea (CT) is an aqueous extract from compost that can correct nutrient deficiencies during crop production and protect cultivation. The research treatment consisted of two factors, namely: the age of harvest and the dose of compost tea. The administration of compost tea consisted of three kinds of doses as follows: no compost tea (P0), 200 mL of compost tea (P1), and 400 mL of compost tea (P2). The experimental plants were harvested at different age, consisting of 25, 35 and 45 days after planting (DAP). The experimental design was Factorial Completely Randomized Design (CRD) with 6 treatments and 9 replications. The data were statictically analyzed using analisys of variance, and differences among value of each treatment were tested with the Duncan Multiple Range Test. The results indicated that compost tea dose and harvesting period treatment affected (P<0.05) leaf length, fresh leaf weight, crude protein content, dry matter digestibility (DMD), and organic matter digestibility (OMD). Meanwhile, it showed not significant effect (P>0.05) on the leaf width and root length. The results suggest that the fertilization treatment of 200 mL of compost tea and 25 DAP could increase productivity (leaf length and fresh leaf weight) of chicory, nutrient content (crude protein) of chicory, and in vitro digestibility (DMD and OMD).
