Abstract
The aim of the research was to prove that the different feed forms affects the performance and carcass production. In total 240 New Lohmann MB 202 day-old chickens were randomly divided into five groups of treatment for 35 days of rearing period. There were 6 replications with 8 birds per pen. The chickens were fed starter feed at 1-21 days and finisher feed at 22-35 days with different feed forms: mash-mash (MM), mash-crumble (MC), mash-pellet (MP), crumble-crumble (CC), and crumble-pellet (CP). The data were obtained and statistically analyzed by ANOVA, then followed by Duncan’s New Multiple Range Test. Feed form did not give any effect to feed consumption and weight gain but it affected feed conversion (P>0.05). MP kept the highest rate of feed conversion by the end of rearing period. Carcass yield showed that various feed form on days 0-21 did not affect carcass percentage of broiler chickens. The birds which ate pelleted feed on days 22-35 have higher (P>0.05) carcass weight than those consumed mashed and crumbled feeds. It is concluded that chicken fed with mash-pellet feed had the best feed conversion. Besides, the birds which ate pelleted feed on days 22-35 had highest carcass weight.

Abstract
The improvement of biogas calorific value is required before distributed to users. The improvement of the calorific value can be done by carbon dioxide removal. This study was aimed to investigate the efficiency of biogas combustion after carbon dioxide removal by the absorption using sodium hydroxide (NaOH). In this study, we used 4 types of sodium hydroxide based on its concentration: 5, 15, 25 and 35% i.e N1, N2, N3, and N4 respectively. The absorption using N1, N2, N3, and N4 decreased carbon dioxide content with the increasing concentration of NaOH. The decrease in carbon dioxide content also led to the increase in biogas combustion that represented by calorific value. of biogas. The calorific value after the absorption using N1, N2, N3, and N4 were 10711.73 + 33.98; 1999.53 + 9.93; 1253.43 + 28.43; and 1328.13 + 8.98 kJ respectively. The results also showed that the absorption can increase the water heating value boiled with biogas. The water heating value after absorption using N1, N2, N3, N4 were 187.91 + 10; 225.42 + 1.77; 227.91 + 8.47; and 243.82 + 1.92 respectively. The best performance in combustion is biogas after carbon dioxide absorption using 35% NaOH.

Abstract
Protection of high-quality protein from rumen microbe degradation by cinnamaldehyde might improve feed protein utilization for ruminants. The study investigated the effect of cinnamon bark meal as a source of cinnamaldehyde on in vitro nutrient digestibility. This research consisted of the diet without (control) and with cinnamon bark meal at 1.16, 2.3, 3.5, and 4.6% of feed dry matter (DM) equivalent to 200, 400, 600 and 800 mg cinnamaldehyde per kg DM. Feed consisted of 60% elephant grass, 30% wheat bran and 10% soybean meal. The experiment was conducted using a completely randomized design with three replications. Data obtained were analyzed by one-way analysis of variance (ANOVA) continued by DMRT. The results showed that the addition of cinnamon bark meal up to 4.6% did not affect dry matter, organic matter and crude fiber digestibility, but decreased (P<0,05) rumen crude protein digestibility (48 h) and increased total crude protein digestibility (96 h). It was concluded that the cinnamon bark meal addition up to 4.6% of DM feed or equal to cinnamaldehyde with 800 mg per kg DM feed could increase crude protein digestibility (96 h) without any adverse effects on in vitro nutrient digestibility.

Abstract
The study was conducted to determine the effect of sorghum varieties and molasses addition in silage making on the physical quality, pH, dry matter, organic matter (OM), Fleigh score, and prussic acid content. The study was designed using Completely Randomized Design in the factorial pattern. The first factor was sorghum varieties (super and BMR), and the second factor was the level of molasses (0% and 4% molasses). The pH of silage with molasses (4.45±0.28) was significantly lower (P<0,05) than silage without molasses addition (4.65±0.26). The DM content (16,13±1,83) and Fleigh score (49,91±12,43) were significantly higher (P<0,05) on silage with molasses addition. It can be concluded that BMR sorghum silage resulted in better physical and chemical quality than super sorghum silage. The addition molasses on sorghum silage decrease the pH but increases OM content and Fleigh score. Ensilage process decreases the prussic acid content of sorghum forage. The combination of sorghum varieties and molasses addition was significantly different.

Published: December 2019

Abstract
To reduce production costs, cows should be maintained extensively in the pasture all or half day. Concentrate addition is needed especially for the last period of pregnancy. The study evaluated the performance of cows maintained semi-intensively with concentrate addition. Fifteen Bali cows ca. 3 years old in 6-7 months of pregnancy were divided into two groups. P1 was given forage grown under oil palm trees with addition 1 kg concentrate/head/day, P2 were given 3 kg/head/day. During the research, cows were grazing in the pasture from 6:00 to 17:00, then put in a cage at night with additional 1 or 3 kg concentrate. P2 group resulted 17.48% and 15.8% higher DMD and OMD, respectively, compared with P1 (P<0,05). DM and OM consumption increased 52.23% and 50.87%. Addition of 1 kg or 3 kg did not show differences in cow performances, including cow body condition score, birth weight, calf score, except for birth weight. It was concluded that the addition of 1 or 3 kg of concentrate at the end of pregnancy did not give any effect; from the economic point of view, it is recommended to add only 1 kg concentrate during the last period of pregnancy.

Abstract
Purpose of this study was to examine the effect of nanoencapsulation technology in protecting the bioactive components of mindi (Melia azedarach Linn.) leaf extract. The first step was formulation of the ratio of mindi leaf extract:chitosan:sodium tripolyphosphate (STPP) for nanoencapsulation by ionic cross-linking. The results showed that the optimum formulation ratio of mindi leaf extracts:chitosan:STPP was 1:7:1/175. Nano-capsulation characteristics of the fitobiotic was measured (particle size (PSA), zeta potential value, morphology of nanoencapsulation (TEM), and bacterial growth inhibition). The second step was measuring the bacterial growth inhibition using the well diffusion technique with six treatments and three replications. The treatments were: aquadest (T1), aquadest with 100 ppm antibiotic Tetracycline addition (T2), aquadest with 0,2% chitosan (T3), aquadest with 0,04% STPP (T4), aquadest with 2% mindi leaf extract (T5); and aquadest with nanoencapsulated mindi leaf extract (T6). The results showed that particle size of nanoencapsulation mindi leaf extract was 535.2±12.83 nm with Polydispersity Index (PI) 0.436±0,21 and zeta potential value 59.73±0.35 mV. The formulation of mindi leaf extract was found to possess inhibitory activity against Escherichia coli, Lactobacillus acidophilus, and Salmonella typhimurium. The research concluded that formulation of mindi leaf extract was clear, stabile and had antibacterial activity.

Abstract
Buffalo and crop production systems in Moa Island are closely related to the availability of “lutur” fences, which area inside becomes an enclosure for food crops, buffalo shed and limiting grazing areas. The aim of this study was to observe the use of lutur and traditional grazing systems of buffalo production system in Moa Island. The study conducted in Moa Island, Indonesia, located in Southwest Maluku, on eastern side of Indonesia. A total 261 farmers were involved in this study. Focus group discussion, semi structured interview and direct observation performed. Data were analysed descriptively, for correlation and by one-way ANOVA. The results showed that Lutur ownership for crop were 3-5 units/family with a total area of 0.83±0.48 ha and used alternately between crops and buffalo shed. The family size were strongly related (P<0.05) with area of food crops. Lutur as buffalo shelters was used communally in an area of 0.7-1 ha, which placed by 250-600 buffalos. Communal groups were based on “soa” or “fam” (family relations), to avoiding conflicts among groups. As a conclusion, besides making buffalo management easier, lutur and communal grazing have been maintaining tradition in Moa Island for generations.

Published: December 2019

AbstractThis study was aimed to assess the effect of seasons on the productivity of Bali cows kept in oil palm plantation (OPP). The study used 20 Bali cows and 1 bull, which kept semi-intensively without supplementary feeding. Cow’s reproductive data, grouped according to birth time, dry season (DS) (May-October) and the rainy season (RS) (November-April) from August 2016 to September 2018, were used. These data were used to determine calving interval and calf mortality. Cows were weighed monthly to estimate dry matter consumption, which was calculated using the Minson equations. Calves were weighed at birth and weaning. Cow’s reproductive index (CRI) and cow’s productivity index (CPI) were calculated based on reproductive data and weaning weight. Data were analysed using One way ANOVA. The result showed that during the DS, the consumption was better (1.96%BW) compared to the RS (1.83%BW) (P<0.01). Calf mortality was higher in the RS (19.05%) than the in DS (17.65%), due to high rainfall and humidity. During the two seasons, calving interval, birth and weaning weights, CRI and CPI of Bali cattle in OPP were relatively similar. It is concluded that the seasons did not influence productivity of Bali cows kept in OPP.

Abstract
The Government of Indonesia has been promoting crop and cattle integration in several provinces to increase local cattle supply and reduce the reliance on imports. Tanah Laut district in South Kalimantan was one of those sites selected. Despite being the major cattle producer, more than 50% of beef demand in Tanah Laut district is met by imported frozen beef, and live cattle imports from interisland. This paper examined how the farming systems in Tanah Laut, including cattle production, have been shaped by technical, agro-climatic, socioeconomic and institutional factors. The main method used is informant interviews with farmer group leaders. Key results are: cattle is the main source of income; the cattle distribution program provided the initial breeding stock, but inadequate technical and extension support and inconsistent development programs have resulted in slow cattle population growth; Javanese and Balinese migrants were more inclined to adopt new technology; and women are involved in various farming activities, but their contribution is not acknowledged. The implication is that better understanding of farming systems and underlying socioeconomic and institutional factors is necessary for better development policies to increase local beef supply, as well as facilitating adoption and scaling out of improved technology.

Published: December 2019

Abstract
Prolactin plays important roles in avian reproduction as it induces broody behavior and regulates follicular development. The objectives of this study were to detect Single Nucleotide Polymorphisms (SNPs) of prolactin gene in Alabio and Mojosari ducks and determine the restriction enzymes for genotyping. Genomic DNA was isolated from 50 blood samples per each Alabio and Mojosari ducks. PCR amplification and sequencing were carried out to identify the SNP. In this study, SNP T-6068C was found based on three GenBank sequences alignment. Two SNPs (C-5796A and T-5817C) in intron 4 region were detected based on sequences of Alabio and Mojosari PCR products. Enzymes Fok1, BtsCI, BsrI were detected to recognize the SNP C-5796A. SNP T-6068C can be digested by enzym TspDTI. However no enzym was detected to recognize SNP T-5817C. In conclusion the SNPs detected from this study may be used in future studies to investigate the association of prolactin gene and egg production traits in Alabio and Mojosari ducks.

Abstract
Aceh cattle is one of the local cattle in Indonesia, traditionally maintained by smallholder farmers in Aceh. Improvement of feed quality become an important key to increase the productivity of Aceh cattle. This study was aimed to measure carcass characteristics and meat quality of Aceh cattle, fed by forage and concentrate at different levels. Twelve of male Aceh cattle were grouped into 4 treatments, based on different proportion of forage and concentrates (T1=70:30, T2=50:50, and T3=30:70). After 90 days, the cattle were slaughtered to obtain carcass and non-carcass weights. The meat was analyzed for physical and chemical characteristics. Data were analyzed using one-way analysis of variance and followed by Duncan’s New Multiple Range Test for significant differences. The results showed that T1 had a lower slaughter and carcass weights than other. T2 had the highest carcass percentage compared to other (P<0.05). There were no significant differences on percentage of edible non-carcass and meat quality (pH cooking losses, moisture, fat content, and protein content of meat). However, there were significant differences (P<0.05) on tenderness and water-holding capacity and collagen content. It is concluded that proportion of 50:50 for forage and concentrate might be the best level for Aceh cattle.

Published: December 2019

Abstract
Genetic parameters for egg production traits in Alabio and Mojosari ducks were estimated. Egg production data were collected from 530 Alabio and 461 Mojosari ducks. The ducks were 6th generation of selection program for egg production trait at the BPTU-HPT Pelaihari. Heritability values were estimated using paternal half-sib correlation method in a one-way analysis of variance. The result showed that heritability estimates for body weight at 16 weeks of age were high, in Alabio ducks (0.63±0.242) and in Mojosari duck (0.88±0.269). Heritability for body weight at first egg was 0.55±0.23 in Alabio duck and 0.44±0.222 in Mojosari duck. The heritability estimates for number of eggs from months 1-3 (EN3) and 1-6 (EN6), ranging from 0.30 to 0.46. The heritability for number of eggs from months 1-12 (EN12) was high in Alabio duck (0.62) and moderate in Mojosari duck (0.46). The EN12 had high genetic correlation with EN3 and EN6 (ranging from 0.80 to 0.99). EN12 had a negative genetic correlation with body weight and age at first egg (between -0.81 and -0.21). This finding indicates that EN3 could be used as a selection criteria to increase EN12 in Alabio and Mojosari ducks.

Abstract
This study aimed to investigate the effect of BAV (blend of 9-natural EO mixed with iodized salt) as feed additive in the ration of laying hens, on the quality and chemical compositions of egg. Thirty laying hens (Lohmann Brown, aged 50 weeks) were divided into two groups (control and 2 g/kg BAV) and given for 6 six weeks. Data on hen daily average (HDA), feed intake, feed conversion ratio (FCR), egg quality (weight, length, width, albumen high and width, yolk high and width, yolk colour, shell thickness, shell weight and Haugh unit) and egg’s chemical composition (yolk cholesterol, yolk protein, albumen protein, xanthophyll) were analyzed. The results showed that BAV significantly increased HDA (P<0.05), and had no effect on feed intake and FCR. The addition of BAV increased yolk wide (P<0.05) and tend to improved egg mass and albumen width, but no difference on egg quality observed. The BAV significantly (P<0.05) decrease cholesterol content of yolk, but no effect to xanthophyll level and both of protein content of yolk and albumen. It is concluded that the addition of BAV as feed additive in the ration of laying hens has potential to improve the quality and chemical compositions of egg.

Abstract
This research was aimed to investigate the effects of different doses of NPK fertilization on growth and productivity of Cichorium intybus. The study was carried out in the farm facility of Faculty of Animal Science Universitas Gadjah Mada. There were three treatments: 0 kg/ha (P0), 45 kg/ha (P1), and 60 kg/ha (P2) (3 replications for each). Seeds were planted in a plot of 1 x 1.5 m. Fertilization was performed once prior to cultivation period (day-15). The height and length of plants were recorded once a week for 30 d. Defoliation was conducted when the plant’s height reached 5 cm (day-30). Data observed including plant’s height and length, number of leaves, fresh production, dry matter (DM) and organic matter (OM) production. Data were evaluated by using one-way ANOVA and followed by Duncan’s New Multiple Range test for significant difference. The results showed that P2 significantly increased (P<0.05) the fresh, DM, and OM of Cichorium intybus, resulting 260.8 tons/ha/year of fresh production, 35.53 tons/ha/year of dry matter, and 28.12 tons/ha/year of organic matter. To conclude this study, the increasing dose of NPK fertilized is able to increase the fresh, DM, and OM production of Cichorium intybus.
