Chicken meat is one of the livestock commodities that can meet the protein needs of the community, but there are constraints on the price side. The price of free-range chicken meat tends to fluctuate due to production and demand imbalances and has an impact on price increases. Therefore, there needs to be control so that price increases that occur in free-range chicken meat do not jump sharply The purpose of the study was to determine the factors that influence the amount of freerange chicken meat’s consumption in Langkat Regency. The study was conducted in June - August 2018. The method that used in sampling was the proportionate stratified random sampling method and used the Slovin formula. Primary data collection was carried out by interview techniques using questionnaires to respondents and secondary data collection was obtained from the agencies and agencies assembled and then analyzed with Multiple Linear Regression using SPSS 22 application. The results showed the amount of free-range chicken meat’s consumption in Langkat Regency was influenced partially by income and the number of family members with R² = 0.61.

Rabbits are livestock that can be used as a source of animal protein and have the potential to have meet national meat needs. Further development is needed whit good quality feed and affordable prices. The study aimed to evaluate feed containing corn cobs which were fermented by MOIYL against carcasses in local rabbits. The study was conducted in Bandar Klippa Deli Serdang Village, North Sumatra Province, in January - March 2018. This study used 20 local rabbits with initial weights of 404.4 ± 9.14 grams and experimental designs using a completely randomized design (CDR), which consisted from 4 treatments and five replications. The treatment consisted of P0 = unfermented ration, P1 = 10%, P2 = 20%, and P3 = 30%. The variables measured were cut weight, carcass weight, and carcass percentage. The results showed that corn cobs fermentation with probiotics MOIYL had a significant effect (P <0.01) and not significant (P> 0.05), increasing corn cobs fermented by MOIYL to a level of 30% increasing slaughter weight and carcass weight, but does not increase the percentage of carcass.

Cassava peel was the waste of processing cassava which is promising enough to be used as alternative animal feed. However, cassava peel has a fairly low nutrient content. Fermentation was one of the way to increase the quality of cassava peel. Fermentation used in this research utilized Indigenous Microorganisms (IMO) with the main substance was the cassava peel itself. This research lasted for 3 months started from December 2018 to February 2019 at the Laboratory of Microbiology and Laboratory of Feed Processing Science and Technology Department of Animal Science Faculty of Agriculture University of Sumatera Utara and Laboratory of Agrichemists and Natural Resources at the Industrial Research and Standardization Office of Medan. This research was designed using Completely Randomized Design (CRD) factorial pattern of 3 x 3 with 3 replications, as factor I was the dose of Indigenous Microorganisms (IMO) and factor II was the duration of fermentation. The parameters measured were water content/dry matter, crude fat, crude protein, crude fibre, ash, and Non Nitrogen Free Extract (NNFE) using proximate analysis. The results showed that fermentation of cassava peel using Indigenous Microorganisms (IMO) with the variation of Indigenous Microorganisms (IMO) dose and duration of fermentation give effects, that were increased water content, crude protein, and Non Nitrogen Free Extract (NNFE) and decreased dry ingredient, crude fat, crude fibre, and ash content.

This study aims to examine the effect of complete corn waste based on silagefeed on the percentage of non carcasses on local sheep. The study was conducted at theLaboratory of Animal Biology at the University of North Sumatra in May - August2018. The design used was a Completely Randomized Design (CRD) with 4 treatmentsand 3 replications using sheep with an average initial weight of 11.2 ± 0.4 kg. Thetreatments consisted of four levels of complete silage feed based on corn waste P1(20%), P2 (40%), P3 (60%), and P4 (80%).The parameters observed were: weight,head, foot, skin, tail, trachea and lungs, liver, heart, blood, and digestive tract.Theresults showed that complete feed based corn waste silage did not have a significanteffect (P> 0.05) on the percentage of non-carcass weight such as skin, tail, trachea andlungs, blood and digestive tract, but gave a non-significant effect on the percentage noncarcass weights such as head, feet, heart and liver. The conclusion of complete feedsilage based on corn waste can have a significant influence on the internal non carcass(liver and heart) and external (head and foot) parts of male local sheep. In addition itgives a non significant influence on the non-internal carcass parts (trachea and lungs,blood and digestion) and the external (skin and tail) of male local sheep.

Abstrak. Penelitian ini bertujuan untuk mengisolasi dan mengkarakteristik fungi lignoselulolitik dari limbah sawit sebagai pendegradasi serat (senyawa polisakarida). Penelitian ini menggunakan metode eksplorasi melalui isolasi, karakteristik, uji degradasi lignoselulosa dan identifikasi. Isolasi menggunakan medium selektif yang dimodifikasi mengandung carboxy methyl cellulose (CMC), xylan, lignin dan manan. Dari hasil isolasi diperoleh 16 isolat fungi lignoselulolitik dan 4 diantaranya memiliki kemampuan tinggi dalam mendegradasi lignoselulosa yaitu isolate fungi YLF2, YLF3, YLF4 dan YLF8. Isolat fungi yang diperoleh memiliki karakteristik yang bervariasi meliputi bentuk, permukaan, tepi dan warna koloni. Hasil uji degradasi (hidrolitik) menunjukkan bahwa isolat fungi YLF8 menghasilkan indeks hidrolitik lebih tinggi dibanding fungi lainnya. Berdasarkan hasil dapat disimpulkan bahwa isolat fungi YLF8 termasuk pada strain Trichoderma sp berpotensi sebagai isolat pendegradasi serat dan dapat digunakan sebagai bioktivator dalam fermentasi pakan berserat.Isolation And Characteristic Of Lignocellulolitic Fungi Of Palm Waste As a Fiber Feed Degrading AgentAbstract. This study aims to isolate and characterize lignocellulolytic fungi from palm wastes as fiber degradation (polysaccharide compounds). This research uses exploration method through isolation, characteristic, lignocellulosic degradation test and identification. Isolation using modified selective medium contains carboxy methyl cellulose (CMC), xylan, lignin and manan. From isolation result obtained 16 isolates of lignocellulolytic fungi and 4 of them have high ability in degrading lignocellulose that is fungi YLF2, YLF3, YLF4 and YLF8. The obtained fungi isolates have varying characteristics including shape, surface, edges and colony color. The result of degradation test (hydrolytic) showed that YLF8 fungi isolates yielded higher hydrolytic index than other fungi. Based on the results it can be concluded that the isolates of YLF8 fungi belong to the Trichoderma sp strain potentially as fiber degrading isolates and can be used as bioctivators in fibrous fermentation feed.

Abstract. Yunilas, Ramadhani R, Tapotubun AM, Tapotubun EJ, Nasution MIA, Fariani A, Akbar R. 2025. Evaluation of antioxidant sources in fermented cocoa pod husk as animal feed. Biodiversitas 26: 521-527. Cocoa has pods that have the potential to be used as feed. However, before being applied to livestock, fermentation using local microorganisms is necessary. This study aimed to evaluate antioxidant sources in fermented cocoa pod husk as feed for animal science and fisheries. The design used in this study was a Complete Randomized Design 3 x 3 factorial pattern with 3 replicates. Factor I was the dose of LMO (DM1 = 2%, DM2 = 4%, DM3 = 6%) and Factor II the fermentation time (LF7 = 7 d, LF14 = 14 d, LF21 = 21 d). Results showed that the dose of LMO and the fermentation time had a very significant effect (p<0.01) on phenol content and there was an interaction between the dose of LMO and the fermentation time (p<0.01). The dose of LMO had a very significant effect (p<0.01) and the fermentation time had no effect (p>0.05) on flavonoid content and there was no interaction between the dose of LMO and the fermentation time (p>0.05). The antioxidant content of the best fermented CPH in this study is DM1LF14 with a phytochemical screening was alkaloid (+), phenol (++), flavonoid (++), saponin (-), tannin (+), yield percentage 15.20%, flavonoids 0.20% and phenols 0.87%.
