Abstract

Mannan-oligosaccharides (MOS) is a common prebiotics used as a feed additives. The use of antibiotic can be replaced by MOS to reduce the number of pathogenic bacteria in small intestines of chickens. The objective of this study was to determine the effect of MOS extracted from copra meal on intestinal microbial population and blood profile of broiler chickens. The study was conducted by using 150 day-old male broiler chickens (average body weight 46.00 +  1.41 g). The design of this experiment was a completely randomized design (CRD) with 3 dietary treatments, 5 replications and 10 birds in each replication. The dietary treatments consisted of control diet (corn-soybean meal diet without supplementation of antibiotic and prebiotic), control + 0.1% antibiotic bambermycin, and control + 0.035% MOS. For the first 4 weeks the birds were fed treatment diets, followed by commercial feed for 2 weeks. The parameters observed in this study were intestinal microbes population and blood profiles. The results showed that the administration of 0,035% MOS increased the lactic acid bacteria (LAB) number compared with antibiotics feed (P<0.05), but not significantly different (P >0.05) with the control group. The total aerobic and coliform bacteria were higher in MOS and antibiotic treatment compared than control group. The supplementation of 0.035% MOS from copra meal in diet increased the level of leucocytes which is important to immune response of broilers and its usage was safe because the level of chicken blood profile were within the normal range.

Abstract

The objective of this study was to evaluate the effectiveness usage of Indigofera zollingeriana leaf meal (I) and Sardinella lemuru fish oil (L) in diets on the decreasing levels of cholesterol and lipid metabolism of laying duck. One hundred and forty-four Magelang ducks aged 20-32 weeks, laying periode, with an average body weigth of 1,72±0,12 kg were used, which were divided into 6 groups of experimental diets, 3 replications, and of 8 layers each. A completely randomized design, 3x2 factorial design was used in this experiment. The first factor was usage Indigofera zollingeriana leaf meal which replaced protein soybean meal (0%, 5,5%, 11%). The second factor was usage Sardinella lemuru fish oil (0%, 2%). The results showed that the treatment (I5.5L2) was highly significant affected (P<0.01) the level of triglyceride, HDL, and LDL in the blood. The treatment I0L2 significantly decrease (P<0.05) total cholesterol of blood lipid profile and meat cholesterol. The treatment (I11L2) was highly significantly decreased (P<0.01) egg cholesterol. The conclusion of this study was that feeding Indigofera zollingeriana leaf meal 5.5% and Sardinella lemuru fish oil 2% in laying duck’s diet could maintain the balance of blood lipid profiles by lowering plasma triglycerides, LDL, cholesterol and raising up plasma HDL and plays an important role on lipid metabolism of Magelang laying ducks to produce eggs and meat with low cholesterol content.

Abstract

The objective of the experiment was to study the effect of feeding fermented Jatropha curcas L.meal (JCM) supplemented with cellulase and phytase on the performances of ISA-Brown laying henaged 25-30 weeks. The Jatropha curcas meal was fermented using Rizhopus oligosporus. In this study200 laying hens were used and distributed to 5 treatments and 4 replications in Completely RandomizedDesign. The diet treatments were: R0 = control diet (without JCM), R1; diet contained fermented JCM7.5%, R2; diet contained fermented JCM 7.5% + celullase 200 g/ton, R3; diet contained fermented JCM7.5% + phytase 200 g/ton and R4; diet contained fermented JCM 7.5% + cellulase 200 g/ton + phytase200 g/ton. The parameters observed were feed consumption, hen day egg production, egg massproduction, egg weight and feed conversion ratio. The results showed that feeding fermented JCM 7.5%,both enzyme supplemented as well as unsupplemented significantly decreased (P<0.05) the feedconsumption, hen day egg and egg mass production. However, the treatments did not influence the eggweight. Supplementation of cellulase (R2) or phytase (R3) improved the feed conversion ratio with thevalue as same as the R0 diet.

Abstract

The aims of this study was to determine the effect of substitution of fish meal protein withsilkworm pupae (Bombyx mori) on quail performances and egg quality. The experiment was a completlyrandomized design (CDR) with four treatments and four replications and ten birds of each replication.The treatment diets were R0: diet contain 8% fish meal, without silkworm pupae (control), R1: dietcontain silkworm pupae subtituted of 25% fish meal protein, R2: diet contain silkworm pupae subtitutedof 50% fish meal, protein and R3: diet contain silkworm pupae subtituted of 75% fish meal protein. Theresults showed that substitution of 25% up to 75% significantly (P<0.05) reduced feed conversion ratio,significantly (P<0.05) increased egg production and did not affecting physical quality of quail eggs. Inconclusion, silkworm pupae can be used 25% up to 75% replacing protein fish meal.

Abstract

An experiment was conducted to study the effect of curcumin supplementation inexpose monochromatic light on serum lipid concentrations of sexually mature female magelang duck. One hundred and ninety two female magelang ducks were assigned into a completely randomized design with a 4×4 factorial arrangement and each experimental unit was repeated 3 times, each with 4 female magelang ducks. The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg/duck/day. The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue colors. The data were analyzed by two-way ANOVA. The result showed that serum concentrations of triglyceride, cholesterol, very low density lipoprotein (VLDL), and low density lipoprotein (LDL) were lower (P<0.05) while high density lipoprotein (HDL) were higher (P<0.05) in experimental ducks supplemented with a curcumin dose of 36 mg/duck/day in variety of monochromatic light colors compared to control experimental ducks without curcumin supplementation. The curcumin doses of 18 or 36 mg/duck/day within red, green, or blue light had the potential to modulate lipid metabolism, as indicated by the increased serum concentration of HDL and the decreased serum concentrations of triglyceride, cholesterol, VLDL, and LDL of the experimental female magelang ducks.

Abstract

The liver of female poultry has a vital role as an organ for biosynthesis of the yolk precursor and has a greater chance of experiencing cellular damages. This experiment was designed to study the uses of curcumin and monochromatic light in suppressing liver destruction during the period of yolk biosynthesis in Magelang ducks. One hundred and ninety two female Magelang ducks were assigned into a completely randomized design with a 4x4 factorial arrangement.  The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg.  The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue. The results showed that hydropic and fat degenerations in the livers of Magelang ducks entering laying phase were still in a normal range. There was an interaction effect between curcumin and monochromatic light on the serum SGPT/GOT and liver MDA concentrations (P<0.05). Serum lipid concentrations positively correlated with the increased serum SGPT/GOT and liver MDA concentrations as indicators of liver damages. Supplementation of curcumin and the use of monochromatic light could reduce and suppress liver destruction and damage during laying period.

Abstract

This study aims to analyze the effectiveness of video practicum guides on distance learning in improving biology learning outcomes on enzymes. This research was conducted with the stages of problem identification, planning, action (cycles I-III), observation, and reflection. All stages of learning were carried out in distance learning (online). The research was conducted on 35 students at a high school in Bandung. The assessment instrument in this study consisted of observation sheets and students' cognitive tests at the end of the cycle. The results of observations and cognitive tests of students showed that the average score for the biological value of the enzyme material had increased. There was a significant increase in each cycle, showing the success of the learning strategy by listening to video practicum. Student learning outcomes were also influenced by the teacher management in carrying out the online learning process. This research was expected to provide new information regarding the use of video media in distance learning.
