The research was conducted from June to August 2023. The research design used was a completely randomised design (CRD) with 4 treatments and 5 replicates, each treatment unit contained 10 super native chickens. The synbiotic consists of fermented snail as probiotic and groundnut shell extract as prebiotic. Feed using selfmix with reduced protein content. Synbiotic supplementation in feed consisted of P0 (control), P1 (5 ml/kg), P2 (10 ml/kg), P3 (15 ml/kg). The parameters observed were the weight and length of the small intestine including duodenum, jejenum, and ileum, as well as the final body weight. Data from the study were analysed using Analysis of Variance (ANOVA), if there was an effect of treatment (P &lt; 0.05) followed by honest real difference test. The results showed that the treatment had a significant effect (P &lt;0.05) on duodenum weight and final body weight but had no effect (P&gt;0.05) on jejenum, ileum, or duodenum, jejenum, and ileum length. The conclusion of the study is that synbiotics can increase duodenal weight at the level of 10 ml/kg and final body weight at the level of 5 ml/kg can compensate for the control treatment.</em></p> <p><em>&nbsp;</em></p> <p><strong><em>Keywords:</em></strong><em> super native chickens, synbiotics, small intestine, final body weight</em></p> Shokhirul Imam Ujang Suryadi Rosa Tri Hertamawati Faris Muizzul Haqqi Copyright (c) 2024 Tropical Animal Science 2024-05-09 2024-05-09 6 1 1 12 10.36596/tas.v6i1.1309 PENGARUH PENGGUNAAN TELUR INFERTIL DALAM RANSUM AYAM KAMPUNG SUPER TERHADAP BOBOT POTONG, KARKAS, NON KARKAS, PERSENTASE KARKAS DAN NON KARKAS https://ejournal.uby.ac.id/index.php/tas/article/view/1327 <p>&nbsp;This study aimed to determine the effect of infertile eggs in the feed on slaughter weight, carcass quality and non-carcass quality in super native chickens. A total of 40 super-male chickens aged eight weeks were used in this study. The design of this study used a completely randomized design with a directional pattern with 4 treatments and 5 replications. The treatments in this study included: P0 (100% basal feed without additional infertile eggs); P1 (basal feed 96,7% + 3,3% infertile eggs); P2 (basal feed 93,4% + 6,6% infertile eggs) and P3 (basal feed 90,1% + 9,9% infertile eggs). The data were using analysis of variance (ANOVA), if significant results were obtained, they would be tested using Duncan's Multiple Range Test (DMRT). The results showed that the use of infertile eggs into the feed up to a level of 9.9% could increase the slaughter weight, carcass weight and carcass percentage (P&lt;0.05). The addition of infertile eggs up to the level of 9.9% can also reduce the percentage of non-carcasses in super native chickens (P&lt;0.05). The conclusion of this study is that infertile eggs can be used as feed ingredients for feed up to a level of 9.9% to increase slaughter weight, carcass weight, carcass percentage and can reduce the percentage of non-carcass in super native chickens.</p> Wara Praritis Sabar Suprayogi Salma Aulia Rahma Novi Akhirini Wahyu Subagio Saputro Muhammad Arif Darmawan Pramita Nindya Saraswati Aan Andri Yano Copyright (c) 2024 Tropical Animal Science 2024-05-09 2024-05-09 6 1 13 21 10.36596/tas.v6i1.1327 PEMANFAATAN EKSTRAK MINYAK DAUN JERUK PURUT PADA EDIBLE FILM BERBASIS GELATIN KULIT CEKER AYAM YANG DIAPLIKASIKAN PADA SOSIS SAPI https://ejournal.uby.ac.id/index.php/tas/article/view/1211 <p>Sausage is a product made from minced meat and then mashed and seasoned, put in artificial packaging, with or without cooking.) due to both oxidative and microbiological damage. Chicken feet are a by-product of chicken slaughterhouses (RPA) whose use is limited because they contain a lot of bones and a little meat, but have a high skin content. The chicken leg consists of several parts such as bone, skin, muscle and collagen. Chicken claw contains collagen of 22.94%. In this study there were 7 stages, namely making gelatin, making kaffir lime oil, making samples, dividing samples, organoleptic tests, hedonic tests, and data analysis. The results of this test indicate that beef sausages coated with edible film with the addition of kaffir lime leaf extract are declared fit for consumption. Because this value is still below the total microbial standard according to SNI (1x106 CFU/g), so beef sausage is still suitable for consumption.</p> Fatkur Rohman Zakaria Husein Abdurrahman Purwadi Purwadi Copyright (c) 2024 Tropical Animal Science 2024-05-17 2024-05-17 6 1 22 28 10.36596/tas.v6i1.1211 HUBUNGAN PROTEIN KASAR TERCERNA DAN SERAT KASAR TERCERNA TERHADAP PRODUKSI GAS METAN PADA DOMBA LOKAL JANTAN https://ejournal.uby.ac.id/index.php/tas/article/view/1344 <p><em>This research aims to examine the correlation between digestible crude protein (DCP) and digestible crude fiber (DCF) on methane gas production from fermented rice straw using urea and urine. The material in this study was used included eight indigenous rams aged ± 1.5 years with a weight of ± 20 kg. The feed provided consisted of concentrate and rice straw fermented with urea (P1) and rice straw fermented with urine (P2). Feed was given twice daily, and water was provided ad libitum. Data collection of digestible crude protein and digestible crude fiber was conducted by total collection method in metabolic cages for 7 days, while methane gas production measurement was conducted for 2 x 24 hours. The results showed differences in correlation values between the two types of treatments. Treatment with rice straw fermented with urea had correlation values of 0.937 for digestible crude protein and 0.507 for digestible crude fiber with coefficient of determination values of 87.9% for DCP and 25.7% for DCF. Meanwhile, in the treatment with rice straw fermented with urine, the correlation values were -0.632 for DCP and -0.991 for DCF with coefficient of determination values of 40.0% for DCP and 98.3% for DCF. The conclusion from this research is that the difference in correlation values is caused by the nitrogen source used for fermentation and the presence of accompanying compounds found in cattle urine used for rice straw fermentation.</em></p> Wahyu Subagio Saputro Kabib Efendi Muhammad Arif Darmawan Copyright (c) 2024 Tropical Animal Science 2024-05-19 2024-05-19 6 1 29 34 10.36596/tas.v6i1.1344 PENGGUNAAN LIMBAH KULIT KACANG TANAH DALAM RANSUM TERHADAP PRODUKTIVITAS TERNAK SAPI JANTAN POTONG PERANAKAN FRIESIAN HOLSTEIN (PFH) https://ejournal.uby.ac.id/index.php/tas/article/view/1203 <p><em>This research aims to determine the effect of using peanut shell waste in rations on the productivity of Holstein Friesian crossbreed beef cattle (PFH). This research used 16 of Holstein Friesian crossbreed beef cattle average 1 years old and average body weight 415,28 + 8,98 kg (CV=2,1%). This research treatment was T0: peanut shell 0%, elephant grass 60%, rice brand 10%, tofu dregs 30%., T1: peanut shell 60%, elephant grass 0%, rice brand 10%, tofu dregs 30%. The parameter research are dry matter consumption, crude protein consumption, crude fat consumption, TDN consumption, daily weight gain, feed conversion and feed cost per gain. Based on the research results, it can be concluded that giving peanut shells can be used in fattening rations for PFH. The effect of giving peanut shells on Crude Protein (PK) consumption, TDN consumption, Feed Conversion was very significant (P&lt;0.01). Dry matter consumption (BK) and daily body weight gain (PBBH) were not significantly (P&gt; 0.05). Feed Cost Per Gain, is very significant (P&lt;0.01), T1 is much cheaper than T0, so T1 is more profitable or more efficient.</em></p> Agung Nugroho Purwadi Purwadi Suhardi Suhardi Copyright (c) 2024 Tropical Animal Science 2024-05-25 2024-05-25 6 1 35 39 10.36596/tas.v6i1.1203 PENGARUH BERBAGAI MACAM WARNA PENCAHAYAAN TERHADAP PERFORMA AYAM PEJANTAN PADA FASE STARTER https://ejournal.uby.ac.id/index.php/tas/article/view/1210 <p><em>This research aims to determine the effect of various lighting colours on the performance of male chickens in the starter phase/1-10 days old.

Boyolali as a milk production center which has major livestock potential is also affected by this condition, especially smallholder dairy farmers, namely small farmers with a population of under 10 heads. This condition is very vulnerable to their socio-economic conditions. This research aims to determine the effect of the FMD outbreak on milk production and economic income at the smallholder farmer level. The results of this research can then be used as a basis for efforts to handle the outbreak, appropriate and measurable recovery efforts to maintain the economic resilience of smallholder dairy farmers in Boyolali to avoid bankruptcy. </em><em>This research was carried out using a survey method in 6 milk producing sub-districts in the Boyolali region. Sampling was taken using purposive sampling based on ownership of dairy livestock under 10 heads among smallholder farmers. </em><em>The research results showed that 99% of dairy farmers whose livestock were affected by FMD experienced a decrease in production by an average of 55%. Farmers must increase maintenance expenditures for treatment by an average of 33% of normal production costs. The average income of smallholder dairy farmers has decreased by 75%. Some extreme cases experienced by breeders include livestock deaths and 5% of livestock having to be culled, and breeders switching professions other than farming. </em><em>The conclusion of this research is that PMK containers reduce the productivity of people's dairy cattle and affect the resilience of people's dairy farming businesses.</em></p> Purwadi Purwadi Aris Budi Prasetyo Copyright (c) 2024 Tropical Animal Science 2024-06-19 2024-06-19 6 1 55 59 10.36596/tas.v6i1.1394
