Abstract

The study aimed at investigating the population, the protein profile and the ultrastructure of adult worms in the intestine of domestic chicken treated using Areca catechu crude aqueous extract. Fifty domestic female chickens of 6 weeks of age were assigned to 5 groups. Group A (negative control) was not given any treatment and any drug. Groups B, C and D were given the treatment at the doses of 26 mg/mL, 53 mg/mL and 79 mg/mL, respectively. Group E (positive control) was given Pyrantel®. Necropsy was conducted to all of the chickens 14 days after the treatment. Adult worms were collected and counted. The worms used in Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE) and Scanning Electron Microscopy (SEM) were those collected from the jejunum of the chickens in the groups A, B and C. The biggest number of the worms was found in the jejunum. The results of electrophoresis showed that the dose 53 mg/mL gave fewer protein bands than the negative control (21:12 ratio), while the results of the SEM showed that there was cuticle damage and anterior labia abrasion at the dose of 53 mg/mL. The Areca catechu crude aqueous extract showed anthelmintic activity potential by reducing the number of the adult worms, lowering their protein profile and damaging the A. galli worms in the intestine.

Abstract

This experiment was aimed to evaluate chemical composition, in vitro rumen fermentation, digestibility and methane emissions of some insects, i.e. Jamaican field cricket (JFC), mealworm (MW) and black soldier fly larvae age 1 and 2 weeks (BSF1 and BSF2). Insect samples were oven-dried at 60oC for 24 h, and ground to pass a 1 mm sieve. The ground samples were used subsequently for chemical composition determination and in vitro rumen fermentation test. Incubation was carried out in a water bath maintained at 39 ºC for 48 h in three replicates. Results revealed that all insect meals contained high crude protein, i.e. above 40% DM. Proportions of neutral detergent insoluble CP (NDICP) and neutral detergent insoluble CP (ADICP) were high in the insect meals than that of soybean meal (SBM), and these were particularly very high in BSF2. All insect meals had lower IVDMD and IVOMD than that of SBM (P<0.05). All insect meals had lower methane emissions as compared to SBM at 12, 24 and 48 h (P<0.05). It can be concluded that insect meals are potential protein supplements and have low methane emissions in vitro. However, their digestibility is rather low and may limit their utilization.

Abstract

This study aimed to explore physical characteristics and its correlation to feed digestibility in goat.Sixteen Ettawah Grade goats in the second milk production periods and in the 4-5th month of lactationwere used in this study. The study was arranged with completely randomized block block design basedon milk production as replications. The goats were fed ration containing 16% of crude protein and 65%of total digestible nutrients (TDN). Some of crude protein content were supplied by urea. The treatmentswere control ration (without urea; T0), ration with 0.4% urea (T1), ration with 0.8% urea (T2), andration with 1.2% urea (T3). Parameters observed were feed digestibility, fecal extended level (FEL), andfecal rough particle distribution (FRPD). Data were analyzed using correlation-regression to find thecorrelation between fecal characteristics and feed digestibility. The results showed that urea content inthe rations up to 1.2% of dry matter did not affect dry mater digestibility, water content and fecalcharacteristics (FEL and FRPD). There were highly negative correlation (r= -0.665) between feeddigestibility and water content of feces as well as feed digestibility and FEL (r= -0.553), whilecorrelation between digestibility and FRDP was positive (r=0.608). The conclusion of this study waswater content, degree of FEL and FRPD can be used to determine the quality of feed. If feces composedof finer texture, dried and small particles indicated having better digestibility, while if feces composed ofrough texture, wet, and large particles indicated having low digestibility.

Abstract

This experiment aimed to observe the effect of herbs (Black Cumin,Curcuma zeodharia,Curcumamangga, and Curcuma aeruginosa) supplementation on milk yield and milk quality (milk fat, milkprotein, milk lactosa and mastitis status) in lactating dairy cows suffering mastitis. Twenty cows in 2nd-4th lactation suspected mastitis subclinical (++) were used in the experiment. Completely randomizeddesign was used in this experiment with 5 treatments (A. Non Herb; B. Black Cumin; C. Curcumazeodharia; D. Curcuma mangga, and E. Curcuma aeruginosa) with four replicates per treatment. Thecollected data were analyzed by analysis of variance and difference between the treatment effects wastested by using Duncan’s Multiple Range Test. The results showed that supplementation of herbssignificantly increased (P<0.01) milk yield, milk protein, milk lactosa and significantly decreasedmastitis status and did not significant affect milk fat.

Abstract

This research aimed to analyze polymorphism of the growth hormone (GH) gene and its implication on digestibility of low and high quality feed. Forty bulls Ongole Grade (OG) and 30 bulls Fries Holland Grade (FHG) had been selected and subjected for an experiment to measure body weight gain, dry matter intake, feed efficiency and feed digestibility. The treatment was crude fibrous feed from various plants with a fibre weight of 15% (P1: low quality) and 22.5% (P2: high quality). The 389 bp of GH gene was amplified (F = 5'-CCCACGGGAGAGAATGAGGC–3'; dan R = 5'-TGAGGAACTGCAGGGGGPA-3') and digested using Msp1 restriction enzyme. Polymorphism between OC and HFC bulls was 45%. The FHG bulls' weight gain were significantly higher than of OC (P<0.05) at first to third week, but become similar (P>0.05) at fourth week. It was concluded that the polymorphism between FHG and OC was high and HFC have a growth response and feed efficiency higher than those of OC.

Abstract

This research was aimed to analyze vitamin E and C supplementation in feed on meet quality,thiobarbituric acid reactive substances (TBARS) and myoglobin level of muscovy duck. This researchused 84 Indonesian muscovy duck divided into 7 group of experimental diet, namely E0C0 : basal feedwithout vitamin E and C supplementation, E400 : basal feed with 400 IU of vitamin E supplementation,E600 : basal feed with 600 IU of vitamin E supplementation, C400 : basal feed with 400mg vof itamin Csupplementation, C600 : basal feed with 600mg of vitamin C supplementation, E200C200 : basal with 200 IUof vitamin E and 200mg of vitamin C supplementation, E300C300 : basal feed with 300 IU of vitamin Eand 300mg of vitamin C. A completely randomized design was applied and each treatment had 4replications. The data were analyzed using analysis of variance. Analysis of variance showed thattreatments significantly affect (P>0.01) meat quality, myoglobin level and TBARS level. Vitamin E andC was proven able to improve final pH of muscovy duck meat. Supplementation of 300 IU of vitamin Eand 300mg of vitamin C at feed with 21% of protein and 3100 kcal/kg of energy could improve DIA,cooking loss, flavor, and color of muscovy duck meat; however, the highest meat tenderness wasresulted from 400 IU vitamin E supplementation.

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 aim of study was to evaluate the effect of dietary vitamin E supplementation in Kedu andCemani hens reraed in situ and given farmer-formulated diet on egg performances. A total of 120 femaleand 24 male birds were equally divided into two groups of Kedu and Cemani, with average body weightof 1890+216.79 and 1830+396.23 g, respectively. Basal ration was based on the diet formulated by thefarmer (R1) consisting of corn (30%), rice bran (50%), protein concentrate (15%), and premix (5%).Dietary treatments evaluated were R1 (without additional vitamin E), and the other three were theinclusion of DL α-tocopheryl acetate into the R1 diet up to 2 (R2), 4 (R3) and 6 IU (R4). The experimentwas arranged in a Randomized Block Design with 4 treatments, and 2 different groups of hen (Kedu andCemani) were assigned as block. Parameters observed were feed consumption, hen day production, feedconversion ratio, egg quality, fertility, and hatchability. The result showed that vitamin Esupplementation did not affect whatever parameters, except egg fertility. Egg hatchability between Keduand Cemani hens was significantly different (p<0.05). Trend comparison test indicated significantlylinear (p<0.05) for fertility and hatchability. In conclusion, vitamin E supplementation up to 6 IUincreased linearly egg fertility and hatchability of about 5-8%, and egg hatchability of Kedu hens washigher (11%) than that of Cemani.

Abstract

This study was aimed to analysis the effects of roughage sources and oil sources in a total mixed ration (TMR) on voluntary feed intake, digestibility and blood chemistry. The study was conducted using four crossbred Thai Native X American Brahman cattle, aged 1.5 years old and with a live weight of 177±34 kg, which were trialled by using a 2x2 factorial in 4×4 Latin square design. All cattle received TMR diets supplemented with bagasse and palm oil, bagasse and sunflower oil, rice straw and palm oil, rice straw and sunflower oil. Each period of feeding lasted for 21 days. During the experimental periods, all cattle were fed ad libitum and with a water supply. The results revealed that roughage sources and oil sources did not affect voluntary feed intake, digestibility and blood chemistry. It was concluded from this experiment that using bagasse or rice straw as the roughage sources with palm oil and sunflower oil mixed in the TMR were suitable for use in beef cattle diets, especially using bagasse with palm oil because of the lowest price (0.28 USD/kg) when compared to the other treatments.
