Gastrointestinal parasitic infections cause economic losses in large ruminant’s production including swamp buffalo in tropical areas. The basic epidemiological data and impact of the infections in swamp buffaloes in Indonesia are very limited. A cross sectional study was conducted to measure the prevalence, to identify the risk factor, and to evaluate the impact of gastrointestinal parasites infection on production performance (BCS and girth) of swamp buffalo in five Sentra Peternakan Rakyat (SPR) in Banten Province, Indonesia. A total of 340 fecal samples were collected and examined microscopically using modified McMaster technique. The risk factors scrutinized in this study were sex, age, farming managements, and agroclimate. Infection was found in 128 buffaloes (37.65%) consisted of Nematodes, i.e. Toxocara (0.88%), Strongyles (8.24%), Trichuris (5.29%), Strongyloides (2.94%), and Coccidia of Eimeria (30%). Age of buffaloes was the only significant risk factor for the infection. The highest infection rate was occurred in the group of pre-weaned calves (63.83%) and the lowest was found in the adults (29.66%). Pre-weaned calve group was 8.519 and 8.435 times more likely to be infected with nematodes and protozoa, respectively. The Spearman correlation test showed that the girth was negatively low-correlated and significantly to the EPG of Toxocara vitulorum, the number of protozoa oocyst as well as the prevalence of gastrointestinal parasitic infections. BCS was not related to the infections. In conclusion, low prevalence of gastrointestinal parasitic infections potentially reduce the production performance of swamp buffaloes in the SPRs of Banten Province, Indonesia.

The research was aimed to evaluate the inclusion effect of dahlia tubers inulin (DTI) combined with Lactobacillus sp. in dietary protein step down on villi development and growth of KUB chicken. The experiment was arranged in a completely randomized design using 160 birds of one-day-old KUB chicks (body weight was 26.32±1.19 g) divided into 5 treatments with 4 replications. The treatment applied were: (1) P180S: ration with 18% protein with the addition of 1.2% DTI and 1.2 mL (108 cfu/mL) Lactobacillus sp. provided since one-day-old, (2) P15: ration with 15% protein without DTI and Lactobacillus addition and was given from 8-day old, (3) P18: ration with 18% protein without DTI and Lactobacillus addition and was given from 8-day old, (4) P15S: ration with 15% protein with the addition of 1.2% DTI and 1.2 mL Lactobacillus sp. offered from 8-day old, and (5) P18S: ration with 18% protein with the addition of 1.2% DTI and 1.2 mL Lactobacillus sp. offered from 8-day old. The experimental birds allocated in the treatments 2 to 5 were fed ration with 21% protein from hatching until 7-day old. Variables observed were the jejunal pH, total Coliform and lactic acid bacteria (LAB), villi height, protein digestibility, final body weight, and carcass percentage. Data were subjected to analysis of variance (ANOVA), and followed by orthogonal contrast test. Orthogonal contrast test showed that feeding 18% dietary protein fortified with a combination of 1.2% inulin dahlia tuber and 1.2 mL Lactobacillus sp. given since one-day-old significantly (P<0.05) affected the height of jejunal villi, protein digestibility, carcass percentage, final body weight, jejunal pH, and Coliform number. In conclusion, feeding 18% dietary protein fortified with a combination of 1.2% of inulin dahlia tuber and 1.2 mL of Lactobacillus sp. since one-day-old increases the height of the jejunum villi and growth of KUB chicken.

This study aimed to measure the effect of L-Arginine supplementation in the ration of laying duck and in-ovo injection of L-Arginine during egg incubation on breast muscle dimensions and carcass percentage of local duck. A total of 500 fertile eggs were obtained from laying ducks fed ration without supplementation of L-Arginine containing 1.04% digestible Arginine and 500 other fertile eggs were obtained from laying ducks fed ration supplemented with 0.25% L-Arginine containing 1.29% digestible Arginine. The eggs were subjected to 4 treatments with 5 replications. The treatments were: 1) eggs collected from laying ducks fed ration supplemented with 0% L-Arginine and in ovo injected with 0% L-Arginine during egg incubation as a control (P0); 2) eggs collected from laying ducks fed ration supplemented with 0% L-Arginine and in ovo injected with 1.5% L-Arginine during egg incubation (P1); 3) eggs collected from laying ducks fed ration supplemented with 0.25% L-Arginine and in ovo injected with 0% L-Arginine during egg incubation (P2); and 4) eggs collected from laying ducks fed ration supplemented with 0.25% L-Arginine and in ovo injected with 1.5% L-Arginine during egg incubation (P3). In-ovo injection of L-Arginine was performed on day 8th of incubation by injection of 1.5% L-Arginine into albumen using automatic syringe with a depth of 10 mm. The 180 day-olds hatched unsexed ducks were divided and moved into the pens according to the treatment groups. At the aged of 8 weeks, a male duck and a female duck from each experimental unit were measured for live weight and carcass weight, then the right Pectoralis major muscle sample was taken for histological analysis of myofibril. The results showed that supplementation of L-Arg in the ration of laying ducks and in-ovo injection of L-Arginine during egg incubation could increase muscle mass (number, diameter, and surface area) of the myofibril, live weight, and carcass percentage of offspring ducks compared to control offspring ducks. In conclusion, L-Arginine supplementation in the ration of laying ducks and in-ovo injections of L-Arginine into the eggs during incubation could increase breast muscle dimensions and carcass percentage of offspring local ducks.

The purpose of the study was to examine the supplementation effects of glucomannan extracted from a porang tuber (GEPT) on body resistance and growth performance of broiler chickens. A total number of 160 one-day-old broiler chickens with the average body weight of 42.39±0.58 g was kept for 35 days. The study was arranged in a completely randomized design with 5 treatments and 4 replications (8 birds each). The dietary treatments were T0= basal ration, T1= basal ration with the addition of 0.05% GEPT, T2= basal ration with the addition of 0.1% GEPT, T3= basal ration with the addition of 0.15% GEPT, and T4= basal ration with the addition of 0.2% GEPT. Parameters measured were the population of lactic acid bacteria (LAB), Coliform count, relative weight of lymphoid organs (bursa fabricius and spleen), heterophils-lymphocytes (H/L) ratio, body weight gain, feed consumption, feed conversion ratio, and mortality. Data were subjected to analysis of variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT) at 5% probability. The results showed that supplementation of the diets with GEPT significantly increased (P<0.05) LAB population, decreased (P<0.05) Coliform count in the jejunum and ileum, and H/L ratio, but did not affect the relative weight of lymphoid organs, and growth performance. In conclusion, diet added with 0.1% GEPT improved the balance of intestinal microflora and increased body resistance, without any negative effects on the lymphoid organs and growth performance of broiler chickens.

The objective of the experiment was to investigate the effects of supplementing laying hens with purified amino acids (PAA) derived from the blood of animal slaughter house on their egg production, egg quality, and immune response. The experiment was based on completely randomized design. A total of 144 Isa Brown laying hens (56-weeks old) were randomly allotted to 4 treatments with 4 pen replications (control, T1: 0.05%, T2: 0.1%, and T3: 0.5% PAA). Each pen housed nine laying hens. The laying hens were reared under a deep litter system. Once a week, a total of 12 eggs of each treatment were collected for egg quality analysis. At the end of the experiment, blood samples were collected for biochemical analysis and cytokines profiles using ELISA kit assays. Hen day egg production and hen house egg production increased significantly (P<0.05) along with the increase in PAA supplementation. The average egg weight increased significantly (P<0.05) with PAA supplementation. Significant differences (P<0.05) were also found in egg shell strength, shell thickness, and albumen ratio. Blood biochemical variables, such as glucose, total cholesterol, blood urea nitrogen (BUN), total bilirubin, and glutamate oxalate transaminase (GOT) were within the normal range. However, the glucose was highest in the control group. Whereas, the total cholesterol and total bilirubin were highest in T2 as compared to control group. Plasma immunoglobulin A (IgA) and immunoglobulin G (IgG), interleukin-1 (IL-1), interleukin-2 (IL-2) concentrations were not affected by PAA supplementation. Plasma interferon gamma (IFNγ) of PAA supplemented treatment groups was significantly (P<0.05) lower than the control group. However, tumor necrosis factor alpha (TNFα) was significantly (P<0.05) higher in T2. On the basis of these results, we conclude that PAA supplementation improved the production performance of laying hens without affecting their health.

Feed cost contributes 80% of the total cost of production in quails. The utilization of cricket meal as a protein source can be a solution to reduce feed costs. The cricket has a high nutritive value, especially protein content, and is one of potential insects to be used as a source of alternative protein to replace fish meal in animal diet. This study aimed to evaluate the effect of cricket meal on the production and physical quality of japanese quail egg (Coturnix coturnix japonica). The experiment used 200 five-week-old female quails with an average body weight of 125.4 g. The completely randomized design (CRD) was employed for the experiments with 5 treatments and 4 replications (10 birds per replication). The dietary treatments were T0: diet without cricket meal, T1: diet containing 2% cricket meal to replace 25% of fish meal, T2: diet containing 4% cricket meal to replace 50% of fish meal, T3: diet containing 6% cricket meal to replace 75% of fish meal, and T4: diet containing 8% cricket meal to replace 100% of fish meal. Results revealed that utilization of cricket meal in the quail ration significantly increased egg production (P<0.05) and positively affected physical quality of quail eggs, such as egg weight, egg white weight, eggshell weight, and yolk score. It can be concluded that cricket meal can partially or fully replace fish meal in the diet of layer quails.

The effects of ginger and pineapple juices on pH, color (L*, a*, b*), thiobarbituric acid reactive substances (TBARS), sensory intensity, and sensory preference of culled goat meat were determined.Completely randomized design (CRD) and randomized completely block design (RCBD) were applied for physicochemical attributes and sensory profiles, respectively. In raw condition, the pH of ginger-marinated sample was higher than that of pineapple-marinated sample. The increased trend in pH was found in the ginger-marinated and control-marinated samples, while the decreased trend was found in pineapple-marinated sample. A better redness stability of ginger-marinated sample was observed during the storage. Both plant juices had significant effects on controlling the malonaldehyde (MDA) formation. Ginger-marinated sample exhibited a brighter red color, less gamey odor, stronger marinated odor, and higher preference. In cooked samples, increasing pH but still with similar trend as in all raw samples was recorded. L* and b* of all samples were decreased on the fifth day of storage, while a* of ginger-treated sample was immensely elevated. Marinated juices were significant on retarding MDA formation along with less browning color and gamey aroma intensities. Reddish-brown color and stronger marinated odor resulted in high preferences on ginger-marinated sample. Less brown color in pineapple-marinated sample contributes to lower color and overall acceptances. In conclusion, ginger juice had a significant effect on covering the gamey flavor and showed positive effect on other sensory-supported attributes.

Indonesia governs the post-entry observation through the Animal Quarantine Installation (AQI) as a precautionary measure to minimize the risk of the entrance and the spread of animal infectious organism and disease of import animals. However, wastes generated from their activities are potentially pollute the environment. This research aimed to evaluate the pollution from AQI activity on its receiving water body. The study was conducted at 5 companies as follow: PT. A, PT. B, PT. C, PT. D, and PT. E. The samples were taken from their wastewater and the river where the waste was discarded with two replications. Direct measurement was carried out in the field by using water quality equipment to analyze pH, temperature, DO, and TDS. For other analysis, samples collected were preserved in refrigerator at 4 °C before laboratory testing was carried out to minimize microbiological decomposition of solids. Pollution variabels were analyzed by analysis of variance test (ANOVA) with 95% confidence level followed by turkey test. The results showed that there was no difference in pollution from temperature, DO, TDS, TSS, COD, and ammonia variables from 5 companies. In contrast, two variables i.e., pH and BOD indicating the difference among 5 companies (P<0.05). In conclusion, the results of wastewater variables from large-ruminant AQI activity were generally exceeding the Quality Standard of Wastewater for cattle-farming. Thus there is a pollution of water bodies in the environment around AQI due to their activities.

The utilization of crop residue as a feed is very important because the arable land area is relatively limited. The study was aimed to examine the influence of adoption of crop-residue product as a feed. The research was conducted in Maros District by using survey methods from March to August 2015. The number of respondents was 96 farmers scattered throughout the Districts of Bantimurung and Camba as centers of rice, corn plant, and cattle productions. Questionnaires were used to collect data conducted by a trained enumerator. Survey was arranged using a logistic regression model to identify socio economic factors influencing the adoption of crop residue as a feed. Work perception (X2), contact with extension workers (X4), rice cultivated areas (X5), the number of livestock (X6), subjective norm (X7), and difficulty (X8) were socio-economic variables influencing the adoption of crop residue as a feed. However, the variables age (X1), farmer experiences (X3), and the number of family members (X9) had no effect on the adoption of this technology. In conclusion, extension workers play an important role in increasing the adoption of technology by using rice and corn straws as a feed. Likewise, not only the number of livestocks, but also the good perception of the farmers increased along with the increase of feed availability, such as utilization of rice and corn straws.

Cytochrome b gene is commonly used to figure out the genetic variation in animals. This research was designed to explore specific markers of Kebumen Ongole grade cattle and to understand the relationship between Kebumen and Brahman cattle using mtDNA cyt b sequences. The sequence of mtDNA cytochrome b gene of 14 individuals Kebumen Ongole grade cattle and 15 individuals Brahman cattle was determined by using polymerase chain reaction and sequencing with a pair of primer. The haploview software was utilized to linkage disequilibrium (LD) analysis. As a result, 36 SNPs (single nucleotide polymorphisms) with 8 haplotypes were identified in Kebumen Ongole grade cattle. In contrast, a small number of SNPs (7) and haplotypes (6) were observed in Brahman cattle. The homozigosity in Brahman cattle was higher than that in Kebumen Ongole grade cattle cattle. Moreover, based on mtDNA sequences, 50% of Kebumen Ongole grade cattle had 85% similarity with Brahman cattle. The SNP number and LD values of Kebumen Ongole grade cattle were greater than those of Brahman cattle. It was presumed that Brahman cattle might be introduced into Kebumen territory. In conclusion, some of Kebumen Ongole grade cattle have genetic relation with Brahman cattle. In addition, the information of SNP and haplotype results from this research can be used as markers to differentiate breeds of animals.
