Bone meal is a natural source of calcium and phosphorus required for plant growth, but phosphorus can cause problems if they occur in high concentrations particularly will inhibit growth of mycorrhizal fungi. The aim of this study was to find the best diameter size and dosage of bone meal for increasing growth of forage legume Pueraria phaseoloides and for producing arbuscular mycorrhizal fungi (AMF) Glomus etunicatum inoculant. A glass house experiment was laid out in a randomized block design consisted of 13 treatments (control and 12 combination of different diameter size and weight of bone meal) and replicated three times. Bone meal and artificial fertilizer resulted the same effect (P>0.05) on dry matter of P. phaseoloides. Application of 25–40 mg with <250 µm diameter significantly (P<0.05) increased dry matter production. Bone meal reduced significantly (P<0.05) root colonization but increased significantly number of spores compared to that of artificial fertilizer. Reducing bone meal diameter significantly increased root colonization and number of spores of AMF G. etunicatum.

Publisher : Faculty of Animal Science, Bogor Agricultural University

A feeding trial has been conducted to compare feeding value of low and high protein dried distillers grains with solubles (DDGS), and corn gluten meal (CGM) to brown layer in the tropics. Both types of DDGS was included at level 0%, 4%, 8%, 12%, and 16% in the diet while CGM was included at 0%, 2%, 4%, 6%, and 8% in similar content of metabolizable energy (ME) value (2650 kcal/kg) and protein (17%). Each dietary treatment was fed to 4 birds in individual wire cage and replicated 5 times. The trial was performed for 10 weeks and egg production, egg weight, feed intake was measured. At the end of feeding period, manure was collected and analyzed for moisture content while samples of eggs were measured for yolk color and the yolk was analyzed for xanthophyll level. Result showed that feeding Lopro DDGS, Hipro DDGS, and CGM did not affect egg production (egg mass, egg number, and egg weight), however, feeding DDGS resulted in less feed intake (111 g/day) compared to feeding CGM (114 g/day). Feeding DDGS up to 16% did not affect egg production and similar to feeding CGM up to 8%. Feeding high level of DDGS or CGM did not significantly affect the moisture content of excreta which were between 78.1%-81.9%. Increasing levels of DDGS or CGM increased yolk color score related to the higher level of xanthophylls content in egg yolk. The coloring ability of CGM to egg yolk was higher than that of DDGS. In conclusion, DDGS can be fed to layer up to 16% without affecting egg production while CGM can be fed up to 8% in the diet. DDGS can be used as source of yellow pigment for egg yolk as also found in CGM.

The aim of this study was to evaluate the silage quality of king grass (Pennisetum purpureophoides) treated with addition of epiphytic lactic acid bacteria (LAB) prepared from fermented grass extract (FGE) or combined with tannin of acacia. Experiment was arranged to a completely randomized design with six treatments and three replications. Treatments were (A) king grass without additive as a control; (B) king grass + 3% (v/w) of FGE; (C) king grass + 3% (v/w) of FGE + 10 ml of acacia extract (50 g/100 ml); (D) king grass + 3% of FGE (v/w) + 10 ml of acacia extract (50 g/75 ml); (E) king grass + 3% of FGE (v/w) + 10 ml of acacia extract (50 g/50 ml), and (F) king grass + 3% of FGE (v/w) + 10 ml of acacia extract (50 g/25 ml). About 250 g of silage materials were ensiled in 400 ml bottle silos at room temperatures (approximately 28 °C) for 30 days. Variables measured were characteristics of FGE, fermentation characteristics and chemical composition of silage. Data were analyzed by analysis of variance and the significance differences among means were tested by the Duncan's multiple range test. Results showed that the number of lactic acid bacteria in FGE increased from 0.8 × 107 cfu/ml to 2.9 × 107 cfu/ml after 2 days anaerobic incubation. Concentration of lactic acid in silages with addition of FGE or combined with tannin of acacia (B, C, D, E, and F) were higher (P3-N decreased with increasing concentration of tannin. Butyric acid concentration decreased in silages B, C, D, E, and F as compared to that in silage A. Addition of FGE combined with tannin prepared from acacia leaf improved fermentation quality of king grass silage.

An appropriate understanding towards preference of small-scale dairy producers can improve technology adoption. The objective of this study was to understand potential, problem and need of small-scale dairy producers including farmer and his wife. The method used was modification of participatory rural appraisal (PRA) like participatory mapping to detect potential, and Preference ranking to understand problem and need priority. PRA applications were six times during April-September 2009 at central area and non-central area in Enrekang regency. Preference of farmer and his wife toward potential and problem were not different. Only feed technology need was different. Forage sources at central area were more diverse than non-central area but concentrate sources at non-central area were more than central area. Lack of knowledge for feed and concentrate formulation and nutritional requirements, less known of feed use, and low feed quality at dry season were the main problems at central area. At non-central area, lack of knowledge for preserving feed, lack of labour, and feed shortage at dry season were main problem faced by farmers. Knowledge improvement for local feed and complete-feed formulation are priority technology at central area. At non-central area, agricultural waste and forage preserving and complete-feed are needed by farmer.

The antimicrobial activity of garlic extract against Gram-positive and Gram-negative bacterial isolates was well studied. However, reports on antibacterial activity of garlic extract against some pathogenic bacteria in animals in Indonesia, are still limited. Therefore, the aim of this study was to evaluate the antibacterial activity of water and ethanol extracts of garlic against Salmonella typhimurium in chickens, and Streptococcus agalactie, Escherichia coli, and Staphylococcus aureus causing mastitis in dairy cows in Indonesia. A filtrate of fresh garlic was used to determine the antibacterial activity against S. typhimurium at concentrations of 5%, 10%, 20%, 30%, and 40% w/v, whereas, the antibacterial activity of water and ethanol extracts was determined against S. agalactie, E. coli, and S. aureus at concentrations of 5%, 10%, 15%, 20%, and 25% w/v. Results showed that antibacterial activity of 30% garlic filtrate was equivalent to 10% tetracycline. Meanwhile, antibacterial activity of garlic aqueous extract on mastitis bacteria was better than that of the garlic ethanol extract. Aqueous extract of garlic at 20% had the same antibacterial activity as 0.01% ampicillin on mastitis bacteria. Filtrates of fresh garlic can be used to inhibit growth of S. typhimurium and mastitis bacteria.

A research was conducted to investigate the effects of vaccination protocols for Infectious Bronchitis (IB) on egg production, egg quality, and IB antibody titres of laying hens. Different initial vaccination (Control, VicS eye, VicS spray, VicS water, A3 eye, A3 spray, and A3 water) for IB were administered to day-old Isa Brown hens. Half the hens were revaccinated regularly during lay whereas the other hens were not vaccinated. Results showed that initial vaccination treatment had significant effects on hen day egg production and egg quality of egg weight, shell reflectivity, shell breaking strength, shell thickness, albumen height, Haugh Units, and IB antibody titre levels, but had no effect on percentage of shell and yolk colour. Egg weight and shell reflectivity were less favourable in the control hens. In contrast, shell breaking strength and shell thickness were highest for the group that initially received A3 vaccine in water. However, regular revaccination had some deleterious effects on egg production and egg quality. There were no significant effects of revaccination on IB antibody titres. It is concluded that there was little advantage in regularly revaccinating laying hens for IB virus, since they had received appropriate initial vaccination.

The research objectives were to characterize morphometric and genetic distance between populations of Indonesian local goats. The morphological discriminant and canonical analysis were carried out to estimate the phylogenic relationship and determine the discriminant variable between Benggala goats (n= 96), Marica (n= 60), Jawarandu (n= 94), (Kacang (n= 217), Muara (n= 30) and Samosir (n= 42). Discriminant analysis used to clasify body weight and body measurements. In the analysis of variance showed that body weight and body measurement (body length, height at withers, thorax width, thorax height, hert girth, skull width and height, tail length and width, ear length and width) of Muara goats was higher (P<0.05) compared to the other groups, and the lowest was in Marica goats. The smallest genetic distance was between Marica and Samosir (11.207) and the highest were between Muara and Benggala (255.110). The highest similarity between individual within population was found in Kacang (99.28%) and the lowest in Samosir (82.50%). The canonical analysis showed high correlation on canon circumference, body weight, skull width, skull height, and tail width variables so these six variables can be used as distinguishing variables among population. The result from Mahalonobis distance for phenogram tree and canonical analysis showed that six populations of Indonesian local goats were divided into six breed of goats: the first was Muara, the second was Jawarandu, the third was Kacang, the fourth was Benggala, the fifth was Samosir and the sixth was Marica goats. The diversity of body size and body weight of goats was observed quite large, so the chances of increasing productivity could be made through selection and mating programs.

The purpose of this research was to investigate the effect of doxycycline (a tetracycline derivative) administered at disease-prevention dose given daily in the feed and drinking water on the residue level in the broiler-chicken meat. Doxycycline at concentration of 100 ppm was mixed in the drinking water (1 g of doxycycline in 10 L of drinking water) and feed (1 g of doxycycline in 10 kg of feed). Samples of chicken meat were taken every week to measure their residue level. Analysis of doxycycline level was performed using high performance liquid chromatography with extraction method referring to the standard of Association of Official Analytical Chemistry. The result showed that the residue level in the group of chickens given doxycycline through drinking water was higher (P<0.05) than in the group given doxycycline through the feed, except for the result in the 5th week, that showed no significant difference. The highest residue level was found at the first week in the group given doxycycline in drinking water (0.96±0.15 µg/g), while the lowest was found at the sixth week in the group given doxycycline in the feed (0.10±0.01 µg/g). The level of doxycycline residue exceeding the level permitted by the Indonesian National Standard (0.1 µg/g). It can be concluded that doxycycline is not recommended to be given daily both through water or feed to commercial chickens as a disease-prevention agent.

Publisher : Faculty of Animal Science, Bogor Agricultural University

This study was aimed to determine changes of the characteristics of raw pig slurry as liquid organic fertilizer at various storage times. A completely randomized design was used in this research. The treatments were storage times, i.e.: 0, 15, 30, 45, and 60 days. Variables observed were loss of the slurry, degree of acidity (pH), electrical conductivity (EC), total solid (TS), volatile solid (VS), total chemical oxygen demand (tCOD), soluble chemical oxygen demand (sCOD), total nitrogen (TN), ammonia-nitrogen (NH3-N), nitrate-nitrogen (NO3-N), total phosphate (TP), and dissolve reactive phosphate (DRP). The results showed that storage time significantly affected all the observed variables, except the concentration of NO3-N and total phosphate content. The pH, TS, VS, DRP, and losses of slurry lost during storage times increased, while EC, TN, NH3-N, tCOD, and sCOD decreased. Physico-chemical properties of slurry during storage times changed, as a result of organic matter breakdown.

Application of strong bases as curing materials has been widely applied in commercial gelatin industries, but the application of weak bases has not been much done. Application of strong bases as a treatment was not economical and assumed to affect human health. Studies were conducted on the properties of goat skin gelatin manufactured using weak base types of Ca(OH)2 and then compared with properties of commercial gelatin. Skins from Bligon goats of 1.5 to 2.5 years old was used as the raw materials and Ca(OH)2 100 g/l as curing materials. The 2x3 factorial completely randomized design (CRD) with three replications was used as a design study. Two curing times (2 and 4 days) and three concentrations (3, 6, 9% v/v) were used as treatments, and commercial gelatin (pure (P) by Merck, food grade (Fg) and pharmacy standards (Ps)) were used as control. Gelatin produced from goat skins using Ca(OH)2 had properties similar to that of commercial gelatin. The heavy metals (Pb, Cu and Zn) contained in goat skin gelatin still meet the INS standards. The optimum production of gelatin has been generated through the application of 4-day curing time at a concentration of 9% (v/v).
