Various attempts are required to improve the quality of se’i as a traditional beef processed product from The Province of East Nusa Tenggara, Indonesia, since the raw beef commonly used is from thin cull Bali cows. Using raw beef from fatter cows may improve the quality of se’i, but the addition of organic acids such as different citric juices may also improve the quality of se’i. This research aimed to evaluate the quality of se’i processed from beef of cull Bali cows with different body condition scores (BCS) and added citrus juice (CJ) during marination to improve aroma, reduce lipid oxidation and bac-terial contamination. A completely randomized design (CRD) with a 3 x 3 factorial arrangement was assigned in this study. The first factor was the BCS of the cull cow i.e., BCS2, BCS3, and BCS4. The second factor was citrus juice, i.e. no citrus juice as control (NC), Lime juice (LJ), and Kaffir lime juice (KLJ). Results showed that the addition of KLJ improved the aroma and acceptability of se’i, but the addition of LJ failed to improve those parameters in BCS 2. In all BCS, the addition of lime or kaffir lime juice reduced the pH, residual nitrite, lipid oxidation, and the total plate count (TPC). How-ever, in BCS 4 only KLJ reduced the pH but it did not reduce the residual nitrite. In conclusion, the addition of KLJ was more effective to improve the sensory value of se’i, particularly when it was made from thin cull Bali cows (BCS 2). Meanwhile, to improve the shelf-life and the food safety of se’i as indicated by the ability to reduce the residual nitrite and thiobarbituric acid-reactive substances (TBARS) in Se'I, the addition of LJ proven to be more effective than KLJ. To produce the highest qual-ity of se’i, it is suggested to process beef from fat cull Bali cows (BCS 4) with the addition of lime juice for best sensory quality or with the addition of lime juice for longer shelf-life and minimum bac-terial contamination.

The study aimed to determine factors affecting economic profits of beef cattle business in Sakon Nakhon Province. A sample of 400 members of Kor Ror Por Klang Phon Yang Kham Livestock Coop-erative Limited was determined by using Taro Yamane method, and binary logistic regression analysis was used to analyze the data. The findings showed that the variables with the statistical significance of 0.01 included concentrate feeds, roughage, and the raised period of less than or equal to 12 months. They were statistically significant at 0.001 0.000, and 0.000 respectively, and the odd ratios were 1.387, 0.921, and 5.697 respectively. Additionally, the variables with the statistical significance of 0.05 includ-ed Charolais cattle (62.50%) and farm location. The two variables were statistically significant at 0.023 and 0.039 respectively with the odd ratios of 5.083 and 0.595 respectively. If the cows are fed on 1 more kg/day of more concentrated feed, it is likely for the farmers to increase economic profit by 0.921 times and 1.387 times respectively. The probability of economic profit is by 5.697 times if the cattle are raised no more than 12 months. The cross-bred cattle with 62.50% Charolais breed showed the proba-bility for the farmers to gain economic profit by 5.083 times. Finally, those who had farms located next to the farm family’s home were more likely to gain less economic profit by 0.595 times.

African swine fever (ASF) is currently considered the serious contagious disease of the swine in-dustry worldwide. The feed and feed ingredients have been recognized as a potential risk factor for Af-rican swine fever virus (ASFV) transmission. No commercial vaccines and effective drugs against ASFV are available to date. This study aimed to examine the antimicrobial SALTEC™ 512, a formal-dehyde-based additive, at an application rate of 1.0; 2.0; and 3.0 kg/t feed against ASFV in complete swine feed. The effect of SALTEC™ 512 was evaluated by a contaminated ASFV feed assay. Our study reveals that SALTEC™ 512 inactivated ASF/VN/Pig/Hue/1270 strain in complete swine feed at an inclusion rate of 1.0 kg/t feed on Day 1 post inoculation. The most effective action was noticed at an inclusion level of 3.0 kg/t feed on Day 7 post inoculation. The antiviral activity of SALTEC™ 512 against ASF/VN/Pig/Hue/1270 was dose and time-dependent. Overall, SALTEC™ 512 may be a po-tential additive to reduce the risk of ASFV transmission via feed contamination.

The aim of this study was to determine the effect of supplementation of encapsulated Cosmos cau-datus K. leaf extract (ECLE) on performance, carcass and meat quality of broilers at high density pens. Three hundred and seventy broiler chicks were divided into 5 treatments and 5 replications. The treat-ment was conducted on days 15 to 42 in T0 group (10 chicks/m2 + basal feed), T1 (16 chicks/m2 + ba-sal feed), T2 (16 chicks/m2 + basal feed containing ECLE 0.5 g/kg feed), T3 (16 chicks/m2 + ECLE 1.0 g/kg feed), and T4 (16 head/m2 + ECLE 1.5 g/kg feed). ECLE reduced feed consumption, increased body weight gain, improved feed conversion ratio (FCR), increased the European Production Efficien-cy Factor (EPEF) and European Broiler Index (EBI) in T2 and T3 (P<0.05). Carcass weight and per-centage were increased in T3 and T4 (P<0.05). Breast percentage was higher (P<0.05) in T0, T1 and T2; wing and thigh percentages were higher (P<0.05) in T3 and T4; drumstick and giblet percentages were lower (P<0.05) in T3. Drumstick’s pH were higher (P<0.05) in T2, T3 and T4. Thigh fat de-creased (P<0.05) at T4. The redness (a*) in T3 and T4 were significantly better. Overall, at high densi-ty pens, ECLE at 0.5 g/kg feed enhanced broiler performance, carcass percentage, and breast meat quality.

The study investigated the effect of sprouted papaya seed meal (SPSM) on physiological conditions, intestinal bacteria and meat quality of broilers. A 390 broiler chicks were distributed to T0 (control feed), T1 (feed with 2.5% papaya seed meal [PSM]), T2 (1% SPSM), T3 (2.5% SPSM), and T4 (5% SPSM). Blood, intestinal digesta and meat were obtained at day 36. Feeding 2.5% PSM lowered (P<0.05), but SPSM up to 5% had no effect on daily gain. PSM reduced (p<0.05) feed intake, but not SPSM. Feed efficiency was lower (P<0.05) in T4. Feeding 5% SPSM increased (P=0.06) bursa of fabricius. T1, T3 and T4 had lower (P=0.09) heterophils. Mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were lower (P<0.05) in T4. Cholesterol to high-density lipoprotein (HDL) ratio of PSM and SPSM was lower (P<0.05) than control. SPSM at 2.5% increased (P<0.05) serum HDL. PSM-fed birds had lower cholesterol (P=0.07), triglyceride (P=0.09) and lowdensity lipoprotein (P=0.09). PSM or SPSM decreased (P<0.05) serum total protein, albumin and globulin. PSM and SPSM reduced (P<0.05) creatinine. Alanine aminotransferase was reduced (P<0.05) with SPSM at 1 and 2.5%. Ileal lactic acid bacteria to coliform ratio in PSM and SPSM was greater (P<0.05) than in control. Ileal coliform was lower (P=0.08) in PSM and SPSM. PSM reduced (P=0.08) saturated fatty acids, while 1 and 2.5% SPSM increased (P=0.09) unsaturated fatty acids contents of meats. In conclusion, SPSM improved immune competence, blood lipid profile and gut bacterial population of broilers.

Soybean meal is the main source of protein in laying hens’ diet that is generally imported. This study aims to explore the yellow mealworm larvae (Tenebrio molitor) “TM”, and curcuma effects on laying hens’ performances, and physical and nutritional eggs quality. One hundred laying hens were divided randomly into 4 groups. The first group (Control) received a standard commercial diet (SCD), while test groups (TM, TP, and TM-TP) received SCD with respectively 5% TM, 0.50 % curcuma, and 5% TM and 0.50% curcuma. According to the results, Control and TM reduced significantly hen’s bodyweight in the experiment end. However, the curcuma incorporation and TM (TP and TM-TP) kept the stability of bodyweight during the whole period. No effect of diet was observed on feed intake and egg laying rate. Diet had a significant effect on eggs physical parameters (weight, freshness, thickness and rupture force). The mixture of TM and curcuma permitted eggs with good physical parameters. For nutritional quality of eggs, all groups had the same content of ALA and DHA. However, eggs of group receiving a mixture of TM and curcuma had the lowest cholesterol content. Thus, TM and curcuma could reduce soybean importation dependence with improving eggs quality.

Plants that contain a large number of bioactive substances have been used as alternative phytobi-otic additives. The objectives of the current study were to investigate the efficacy of coconut husk ex-tract on broiler performance, ileal digesta characteristic and small intestine morphology. Two hundred and fifty day-old-chicks (DOC) were randomly placed in five treatment groups with five replicates each, and the chickens were reared until six weeks old. Basal ration was hand mixed to ensure the re-quirements in the starter period and finisher period. Treatments were basal ration only (TCT-), basal ration with 40 ppm tetracycline (TCT+), basal ration with 100 ppm coconut husk extract (T100), basal ration with 400 ppm coconut husk extract (T400) and basal ration with 700 ppm coconut husk extract (T700). The variables included feed intake, live weight gain (LWG), feed to gain ratio (FCR), breast meat quality, pH and microbial composition of digesta and small intestine morphology. Data were sta-tistically analyzed using analysis of variances and comparison test using the Duncan’s multiple range test. The results demonstrated that the feed additives significantly increased feed intake, LWG, breast meat protein content, villi height in the ileum, and the height:crypt depth ratio in the duodenum and ileum, and significantly decreased the abundance of Escherichia coli and Staphylococcus aureus and the pH of digesta (P<0.05). Therefore, coconut husk extract could be applied as a phytobiotic feed ad-ditive for broiler chickens to stimulate the growth of broilers, suppress colonies of harmful bacteria in the small intestine and enhance the improvement of intestinal morphology.

The variables included feed intake, live weight gain (LWG), feed to gain ratio (FCR), breast meat quality, pH and microbial composition of digesta and small intestine morphology. Data were sta-tistically analyzed using analysis of variances and comparison test using the Duncan’s multiple range test. The results demonstrated that the feed additives significantly increased feed intake, LWG, breast meat protein content, villi height in the ileum, and the height:crypt depth ratio in the duodenum and ileum, and significantly decreased the abundance of Escherichia coli and Staphylococcus aureus and the pH of digesta (P<0.05). Therefore, coconut husk extract could be applied as a phytobiotic feed ad-ditive for broiler chickens to stimulate the growth of broilers, suppress colonies of harmful bacteria in the small intestine and enhance the improvement of intestinal morphology.","PeriodicalId":17297,"journal":{"name":"Journal of the Indonesian Tropical Animal Agriculture","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44901362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research was conducted to analyze farmers’ risk perceptions and factors that influence farm-ers' decisions in implementing risk management strategies to integrated farming of cattle and crops. This study used a survey method by conducting interviews to 150 respondents who were divided into two patterns based on the composition of the farming practice. Pattern I practice cattle-rice-corn-rice business and Pattern II practices cattle-rice-corn-soybean in Grobogan District, Central Java, Indone-sia. Data were collected in January - May 2019 and were analyzed using probit model on the risk man-agement strategies adopted consisting of credit, insurance, partnerships, and off-farm income. The re-sults showed that 59.15 percent of pattern I farmers and 47.06 percent of pattern II farmers perceived the risk of farming due to climate, market, biological and financial in the high category. Farmers' deci-sions in implementing risk management strategies were influenced by farmers' perceptions of climate, market, biological and financial risks.

The aims of this investigation were characterization, demonstration of the antibiogram pattern and detection of the pathogenicity of Clostridium perfringens (C. perfringens) strains isolated from broiler chickens in Damietta governorate, Egypt. A total of 357 samples representing 202 intestinal contents and 155 liver samples from freshly dead broiler chickens were collected from 18 broiler farms. Isolates of C. perfringens were identified morphologically, microscopically, and biochemically. Forty-seven C. perfringens isolates were recovered, which represented 20.3% of the intestinal contents and 3.8% of the liver samples. The toxins and virulence genes of C. perfringens were investigated using polymerase chain reaction. All of the toxigenic C. perfringens strains were type A and carried netB, tpeL, cpe, and plc genes. The in vitro antibiogram of C. perfringens strains revealed 100% sensitivity to gentamycin and levofloxacin and 100% resistance to nalidixic acid and ceftriaxone. The isolated C. perfringens strains were highly pathogenic and induced signs and lesions of necrotic enteritis as well as 43.3% mortalities in 20-day-old chicks. In conclusion, C. perfringens is an important pathogen that affects broiler chickens due to the presence of virulence genes and the pathogenicity in the inoculated birds.

Broiler meat is the second world's most consumed meat, and the increase in consumption by 2027 is forecasted to be near 35 kg/capita/year. Brazil ranks third in broiler production globally and is the world's largest exporter of chicken meat. To reach proper rearing conditions, broiler farms need to meet good practices of husbandry and welfare. The present study aimed to develop a performance classification model using data mining to evaluate broiler farmers based on detailed flock housing and performance information. The input dataset from 49 broiler farms from a cooperative in Northeastern Brazil was organized with details on the housing characteristics, rearing environment, management, and performance data from flocks. We also added the cooperative technical classification retrieved from the housing conditions and the production index. The input classification had weights attributed to each housing feature. The output variable (target) was defined as the performance classification (PC) index. The dataset was processed using Rapidminer® software using 80% of training and 20% for implementing the random forest algorithm. The prominent variables in classifying the performance were the feed conversion, the daily weight gain, the productivity index, and the cooperative classification criteria. The developed model pointed out a way to auto-classify farms and allow the cooperative to evaluate the farmers' production based on the broiler production and management practices. It was possible to create 'If-Then' rules that enable appropriate decisionmaking by broiler farmers to comply with good practices' norms.
