The purpose of this study was to analyze the response of sheep breeders to the application of feed technology and reproductive hormones. The object of this research is the sheep breeder in the District of Jati Tujuh, Majalengka Regency. This research was conducted by survey using the quantitative descriptive method, determining the research area using the purposive sampling method. Determination of the number of respondents was calculated using the Slovin formula with a confidence level of 90% (r = 0.1) with the results of the calculation amounting to 85 people. The variables measured were Characteristics (Age, Business Scale Level, Livelihood Level, Last Education, Livestock Experience) and Response (Cognitive, Affective, Psychomotor). Data processing in this study used the Kendall Tau Correlation Test Analysis. The results showed that the response of sheep breeders to the Application of Feed Technology and Reproductive Hormones in Jati Tujuh District was in the very weak category, it was because most of the breeders were over 50 years of age with a low level of education, namely elementary school graduates, so that farmers found it difficult to implement and understand information. regarding livestock technology. The data shows that the level of characteristics significantly affects the response of farmers. The results of the study also show that the relationship between the characteristics of the response is in the very weak category or has no significant effect. It can be concluded that the characteristics have a significant effect on the response of farmers. The better the level of characteristics, the better the effect on the response. The relationship between the two variables between the characteristics and the response is in the very weak category.</em></p> Muhammad Matin Muta'Ali Ulfa Indah Laela Rahmah Rahmah Lili Adam Yuliandri Copyright (c) 2023 Muhammad Matin Muta'Ali, Ulfa Indah Laela Rahmah Rahmah, Lili Adam Yuliandri https://creativecommons.org/licenses/by-sa/4.0 2023-10-17 2023-10-17 2 1 1 14 10.31949/tlsj.v2i1.5249 Performa Entog (Cairina moschata) Jantan Yang Diberi Berbagai Imbangan Pakan Berbasis Silase Limbah Sayuran dan Dedak Padi https://ejournal.unma.ac.id/index.php/tlsj/article/view/5250 <p><em>Muscovy duck</em><em> performance is influenced by quality feed, easy to obtain and does not compete with humans. The purpose of this study was to analyze the performance of male mussels fed a balanced feed of vegetable waste and rice bran silage on the performance of male mussels and to obtain a formulation of a balanced diet of vegetable waste and rice bran silage that produced the best mussels performance. The study was conducted experimentally using a completely randomized design (CRD) of 4 treatments with 5 replications. The treatment used was 4 feed balances, namely rice bran with vegetable waste silage, respectively P0 = 100: 0; P1 = 75 : 25; P2 = 50 : 50, and P3 = 25 : 75. The variables observed were ration consumption, body weight gain, ration conversion, and feed efficiency. The research data were analyzed using analysis of variance and if there was a significant difference it was further tested using Duncan's multiple range test. The results showed that ration consumption, ration conversion, and feed efficiency had significant differences. Meanwhile, body weight gain did not have a significant effect. It can be concluded that feeding vegetable waste silage has a significant effect on increasing ration consumption, but reducing ration conversion and feed efficiency. The treatment that produced the best male musk performance was shown at P0.</em></p> Fazar Maulana Dini Widianingrum Aaf Falahudin Copyright (c) 2023 Fazar Maulana, Dini Widianingrum, Aaf Falahudin https://creativecommons.org/licenses/by-sa/4.0 2023-10-17 2023-10-17 2 1 15 20 10.31949/tlsj.v2i1.5250 Perubahan Status Energi Pada Proses Reproduksi Induk Domba Garut Yang Diberi Pakan Komplit Berbasis Hijauan Sorgum dan Indigofera https://ejournal.unma.ac.id/index.php/tlsj/article/view/5251 <p><em>Blood urea nitrogen (BUN) is an indicator of the efficiency of protein use in metabolism which is correlated with energy adequacy status. This study aimed to analyze and measure differences in energy adequacy status of arrowroot ewes in the premating, pregnancy, and lactation phases that were fed a complete diet of sorghum indigofera. The method used experimentally with Completely Randomized Design (CRD). There were 2 feed treatments, namely field grass (RL) as control and complete feed based on forage sorghum indigofera with a composition of 50% sorghum silage + 40% indigofera hay + 10% fine bran (SI) and repeated 14 times. The data obtained were analyzed using a two sample t-test. The results showed that there was a decrease in BUN in both treatments in each phase, but overall the average BUN value did not show a significant difference (P&gt;0.05). Significant differences (P&lt;0.05) only occurred at the beginning of pregnancy, mid and late lactation with BUN values of 21.18±1.04; 13.25±0.60; 15.18±0.67 for RL and 18, respectively. ,61±1.10; 15.86±0.82; 12.43±0.56 for SI. So it can be concluded that complete feed based on sorghum indigofera has the same energy change status as field grass, and in SI it can be used as a substitute for field grass.</em></p> Taufik Rizki Nurrochman Aaf Falahudin Rachmat Somanjaya Copyright (c) 2023 Taufik Rizki Nurrochman, Aaf Falahudin, Rachmat Somanjaya https://creativecommons.org/licenses/by-sa/4.0 2023-10-19 2023-10-19 2 1 21 28 10.31949/tlsj.v2i1.5251 Pengaruh Penambahan Tepung Kedelai Terhadap Tingkat Kesukaan Dan Kandungan Protein Pada Bakso Daging Sapi https://ejournal.unma.ac.id/index.php/tlsj/article/view/6700 <p><em>The aim of this research is to analyze the dosage of using soy flour on the level of preference and protein content of beef meatballs and to obtain a formula for the optimum use of soy flour on the level of preference and protein content of beef meatballs. This research used a Completely Randomized Design (CRD) &nbsp;method with 5 treatments and 4 replications. The ratio of tapioca flour to soy flour for each treatment is respectively P0 (100% : 0%), P1 (75% : 25%), P2 (50% : 50%), P3 (25% : 75%) and P4 ( 0% : 100%). The data obtained were analyzed using analysis of variance (ANOVA). Meanwhile, the protein content uses a descriptive test and if the results of the anova test show a significant difference, continue with the Duncan test. The research results showed that as soy flour was added to beef meatballs, the level of liking for the aroma, texture and taste decreased. The addition of soy flour did not affect the level of preference for the color of the beef meatballs produced. Beef meatball protein with the addition of soy flour is between 16.15 – 23.31%. In conclusion, the best formulation is the addition of soybean flour to P1 with a reddish ash color, the level of liking is somewhat like it, the aroma does not have the smell of soybeans, the level of liking is very like it, the chewy texture is the liking level is somewhat like it and the taste has no taste of soybeans with the level of liking is somewhat like it.</em></p> jajang hermana Aaf Falahudin Oki Imanudin Copyright (c) 2023 jajang hermana, Aaf Falahudin, Oki Imanudin https://creativecommons.org/licenses/by-sa/4.0 2023-10-17 2023-10-17 2 1 29 35 10.31949/tlsj.v2i1.6700 Evaluasi Tingkat Kesukaan Terhadap Sifat Organoleptik Susu Kambing Pasteurisasi Yang Diberi Berbagai Tingkat Ekstrak Jambu Biji Merah (Psidium guajava L.) https://ejournal.unma.ac.id/index.php/tlsj/article/view/6857 <p><em>The aim of this research is to analyze the effect of adding red guava extract on the level of consumer preference for organoleptic properties including color, aroma, viscosity level, taste and taste of pasteurized goat's milk.
