COMMERCIAL CARCASS FAT AND NON-CARCASS FAT DEPOSITS IN THE ADMINISTRATION OF MINERALS (ZN) AND AMINO ACIDS (METHIONINE, LYSINE, AND L-CARNITINE) TO LAMB MEAT
The increasing demand for meat must be accompanied by an increase in the production of fattening sheep. One of the local sheep whose meat is used is the Priangan sheep. The demand for meat is not only the quantity but also the quality of the meat, which influences consumer interest. Low-fat is the consumer's choice when choosing meat. This research aims to test the effect of providing minerals (Zink) and amino acids (Methionine, Lysine, and L-Carnitine) on commercial carcass fat and non-carcass fat. The livestock used were 20 7-month-old Priangan sheep with an average weight of 14.66 kg. Maintenance was for 67 days, of which 7 days were adapted and 60 days were treated. The statistical analysis used was a completely randomized design (CRD) of 4 treatments with 5 replications. If the statistical results show that there is an effect of treatment (P<0.05), then a further test is carried out using the Duncan Test. The treatments observed were (P1): No Treatment, (P2): Giving Zn (60 mg), (P3): Giving Zn (60 mg) + Methionine (3 g) + Lysine (5 g), and (P4): Administration of Zn (60 mg) + Methionine (3 g) + Lysine (5 g) + L-Carnitine (200 ppm). The results showed that the addition of Zn (60 mg) had an effect on carcass fat (back, stomach, right loin, and neck fat), while non-carcass fat components had no effect
Nutrient content, fiber fractions, and rumen fermentation in vitro of mulato grass grown with different cutting age in lowland West Java, Indonesia
One of the major challenges in ruminant production in Indonesia is ensuring the availability of high-quality and adequate forage. Identifying forage varieties with good nutritive value that adapt well to local climate conditions is crucial. This study evaluated the nutrient composition, fiber fractions, and in vitro rumen fermentation of Mulato grass harvested at different cutting ages (30, 40, and 50 days) in the lowlands of West Java, Indonesia. The nutrient content, analyzed using proximate and fiber fraction analysis, showed no significant differences across cutting ages except for ash content, which was lower at 40 days. Mulato grass cut at 30 days had lower acid detergent fiber (ADF), neutral detergent fiber (NDF), acid detergent lignin (ADL), and hemicellulose levels, while its cellulose content was higher compared to grass cut at 40 or 50 days. Rumen fermentation results indicated that grass cut at 30 days had higher in vitro dry matter digestibility (IVDMD), organic matter digestibility (IVOMD), and total volatile fatty acids (TVFA). These findings suggest that Mulato grass harvested at 30 days offers better digestibility and rumen fermentation outcomes, making it a suitable forage choice for ruminants in the lowlands of West Java, Indonesia
GROWTH PERFORMANCE OF LAYING HENS FED DIETS CONTAINING DIFFERENT LEVELS OF PALM KERNEL MEAL AND COPRA MEAL
AbstractFeed plays an important role in livestock metabolism, especially to support growth, maintain body condition, and production. Therefore, efforts are needed to find high-quality feed ingredients that are easy to obtain, sustainably available, do not compete with human needs, are non-toxic, and economical. One alternative feed ingredient that can be optimized to reduce feed costs is industrial waste, such as coconut meal and palm kernel meal. This research was conducted at the Laboratory of the Faculty of Animal Husbandry and Fisheries, Tadulako University, Palu, for five weeks, namely from March 19, 2022 to May 20, 2022. A total of 80 laying hens aged 64 weeks were used in this study, with five treatments and four replications. This study used a completely randomized design (CRD) with further analysis using the Honestly Significant Difference Test (HSD). The variables observed included feed consumption (g), egg production (g), feed conversion, energi intake (kcal), and protein intake (g). The results showed that the treatment had a very significant effect on feed consumption (P<0.01), and had a significant effect on egg production, feed conversion, energy intake, and protein intake (P<0.05). From the results of the study it can be concluded that the addition of 5% palm kernel meal and 5% coconut meal is the most recommended combination as an alternative feed ingredient in laying hen rations.Keywords: Copra meal, laying hens, palm kernel mea
ABUNDANCE OF Succinivibrionaceae BACTERIA IN THE FECES OF CALVES FED TANNINS, AMINO ACIDS, AND THEIR COMBINATION
The purpose of this study was to determine how common Succinivibrionaceae bacteria are in calf feces. Four female calves, with an average age of 6.48 ± 0.51 months, participated in a Latin square trial featuring four dietary treatments: control (C), tannin (T), amino acid (AA), and a tannin-amino acid mixture (TM). Duration of each treatment was 14 days whereby faecal samples were that were harvested on day 14. The treatment trial for 14 days included the collection of faecal samples on day 14 for the extraction of DNA to conduct Next-Generation Sequencing (NGS) analysis. Results showed that the Succinivibrionaceae population grew extensively when treated with T and AA and TM compared with C while AA was most effective. Analysis of bacteria detected five genera and five species. The bacterial genus Ruminobacter dominated in the C (53%) and AA (62%) and TM (58%) treatment groups while Succinivibrio dominated the T treatment group (78%). The species Ruminobacter amylophilus dominated treatments C, AA, and TM but the species Succinivibrio dextrinsolvens dominated treatment T. The results infer that the addition of tannins or amino acids or their combination to the gut environment may help in reducing methane emissions through an alteration in the microbiome composition
Effect of Azolla and Beef Bone Meal Addition on the Nutrient Content of LOF Based on Beef Cattle Manure and Laying Hens Excreta
In Liquid Organic Fertilizer (LOF), the problem that is often found is that the nutrients contained do not reach quality standards. Azolla and beef bone meal are known to contain macronutrients needed by plants, in addition to maximizing the existing content, functional bacteria are also added. This study aims to analyze the effect of the addition of azolla and beef bone meal on macro nutrient content, C-organic, coliform, and viability. The research method uses a completely randomized design (CRD) with 6 treatments and 3 replicates, namely (P1) 25% Azolla + 15% beef bone meal, (P2) 25% Azolla + 20% beef bone meal, (P3) 25% Azolla + 25% beef bone meal, (P4) 25% azolla + 15% beef bone meal + 10% functional bacteria, (P5) 25% azolla + 20% beef bone meal + 10% functional bacteria, (P6) 25% azolla + 25% beef bone meal + 10% functional bacteria. The research data were analyzed statistically using variance analysis and Duncan's multiple range test with the IBM SPSS Statistics 25 program. The results showed that the addition of 25% azolla + 25% beef bone meal (P3) had a significant effect (P≤0.05) on increasing macro nutrient content and functional bacteria viabilty, C-organic, coliform
The Effect of Additioning Microencapsulation Products of Noni Fruit Extract (Morinda citrifolia Linn) in The Ration on The Performance of Developer Phase Sentul Chickens
This study aims to determine the effect of adding microencapsulated noni fruit extract (MEBM) to the feed on the feed consumption, body weight gain, feed conversion, and sexual maturity age of Sentul phase developer chickens. The research was conducted from July to September 2023 at the Test Farm of the Faculty of Animal Husbandry Padjadjaran University. The research method used a Completely Randomized Design (CRD). There were five types of treatments, namely, P0 = basal ration without the addition of MEBM, P1 = basal ration + 50 mg/kg zinc bacitracin, P2 = basal ration + 75 mg/kg MEBM, P3 = basal ration + 150 mg/kg MEBM, P4 = basal ration + 225 mg/kg MEBM, and repeated four times. The measured variables were feed consumption, body weight gain, feed conversion, and sexual maturity age of Sentul phase developer chickens. The data were analyzed using analysis of variance and the differences in effects were tested using the Honestly Significant Difference (HSD) test with P0 as the negative control and P1 as the positive control. The results of the study showed that the addition of microencapsulated noni fruit extract (MEBM) at levels of 225 mg to the ration providing the best result on body weight gain and feed conversion, but it does not have a significant effect on feed consumption and sexual maturity age of Sentul phase developer chickens. It can be inferred that the addition of MEBM up to 225 mg/kg in the ration can replace the role of AGP zinc bacitracin as an antibiotic

PARTNERSHIP SCHEME IMPLEMENTATION AND BUSINESS SUCCESS IN BROILER FARMING: AN EMPIRICAL ANALYSIS
The partnership scheme in broiler farming aims to enhance farmers' productivity and profitability through technical support, market access, and the provision of production inputs. However, variations in its implementation effectiveness significantly impact farmers' business success. This study examines the relationship between the level of partnership scheme implementation and the success of broiler farming businesses in Kutai Kartanegara Regency, East Kalimantan. A quantitative approach was employed, using structured questionnaires to collect data from 220 farmers selected through purposive sampling. Data were analyzed using descriptive statistics, Pearson correlation, and multiple linear regression to identify key factors influencing business success, including feed management, breed quality, animal health, and technical assistance. The findings indicate that the implementation of partnership schemes has a positive and significant relationship with broiler farming success, with feed management (β = 0.45, p < 0.01) and breed quality (β = 0.39, p < 0.05) being the most influential factors. However, challenges such as fluctuating feed costs, limited access to technology, and uneven technical support hinder the optimal application of partnership schemes. Therefore, improving infrastructure, expanding access to technology, and developing cost-stabilization strategies are essential to enhancing the effectiveness of partnership schemes and ensuring the long-term sustainability of broiler farming businesses
PERFORMANCE EVALUATION OF SENTUL GRAY CHICKEN AND THEIR ASSOCIATION WITH TLR1A GENE POLYMORPHISM
The study examined the association between TLR1A gene polymorphism in exon 4 and the performance of Gray Sentul chickens. Conducted at the Jatiwangi Poultry Breeding Development Center. DNA from 30 males and 30 females was analyzed using PCR and sequencing to identify Single Nucleotide Polymorphism (SNPs). Data processing employed BioEdit and MEGA 11. Results revealed five mutations in males (g.775T>C, g.844 T>A, g.858C>T, g.983C>T, and g.1163G>A) and three in females (g.721G>A, g.983C>T and g.1163G>A). Males showed higher body weights, with optimal growth at 1–2 months. Peak egg production occurred at 41 weeks (HDP 44.97%), and the highest egg weight (46.93 g) at 55 weeks. Specific SNPs associated with performance traits include g.775T>C for body weight in males, g.1163G>A for body weight in females and egg production, and g.721G>A and g.983C>T for egg weight. This study concludes that the TLR1A gene can be used as a genetic marker to improve the performance of grey Sentul chickens
