Abstract

A research was conducted to generate a mathematical model for estimating the rearing cost of replacement dairy cattle. This research uses a survey method to collect data regarding farmer expenditures in raising young dairy cattle. Data collection involved 67 farmer who kept 231 replacement dairy cows with various ages, from birth up to two years of age. Data analysis used linear regression to estimate an equation model for describe a causal relationship between the partial total cost (TCp) with the period of rearing the cattle (q). The analysis performs two model equation namely quadratic and cubic cost function. The second model performs a goodness of fit better, with an S-shaped curve, .  Analysis of variance result in the R2 of 0.67. Based on the estimated cost equation model above, total cash expenditure for two-year-old pregnant heifers reached IDR 15,565,800. If the opportunity cost of a calf is included in the cost calculation, the cost will increase to IDR 19,102,800. Compared to the local price for two-year-old heifers, farmers still have a price margin of IDR 6,211,200.Keywords: replacement cows, total cost partially, cost function

Abstract

Cow feces is the rest of the digestive process of the livestock body, while coffee grounds are the rest of coffee brewing, and both are organic materials with fixed carbon that can be utilized as fuel. The purpose of this study was to determine the effect of the addition of coffee grounds in processing dairy cow feces into briquettes on physical properties (color, texture, density), chemical properties (moisture content, ash content, volatile matter, and fixed carbon), and energy value (calorific value, temperature, flame duration). This research method is experimental, with four treatments, each consisting of five repetitions. The treatments in this study consisted of P1 (100 g dairy cow feces + 20 g coffee grounds), P2 (100 g dairy cow feces + 40 g coffee grounds), P3 (100 g dairy cow feces + 60 g coffee grounds), P4 (100 g dairy cow feces + 80 g coffee grounds). The data obtained were analyzed statistically with ANOVA at = 5%. Further tests were carried out using the Duncan test. The results showed that the addition of coffee grounds to dairy cow feces briquettes had a significant effect (p<0.05) on physical properties (density), chemical properties (moisture content, ash content, volatile substances, fixed carbon) and energy value (calorific value, temperature, and flame duration). The addition of 80 grams of coffee grounds (P4) gave the best effect on the performance of dairy cow feces briquettes with a moisture content of 6.94%, ash content of 25.47%, volatile matter of 18.58%, fixed carbon  of 49.02%, calorific value of 3717 cal/gr, temperature of 463°C.

Abstract

The study investigating the relationship between body weight and egg weight in Padjadjaran quails, encompassing both layer and broiler types, was conducted at the Quail Breeding Center within the Faculty of Animal Husbandry at Universitas Padjadjaran. The research involved 100 female quails, consisting of 50 from each type, all of which were 15 weeks old, along with their eggs. The primary aim was to assess the strength and nature of the relationship between body weight and egg weight in these quails. A correlational method was employed for the analysis. The findings revealed a strong correlation between body weight and egg weight in Padjadjaran layer quails, indicated by a correlation coefficient of 0.792. The relationship was represented by the regression equation \( y = 0.0586x + 0.8429 \), which had a relatively high coefficient of determination (\( R^2 \)) of 0.6281. Conversely, the results for Padjadjaran broiler quails indicated a weak correlation, with a correlation coefficient of 0.374. The regression equation for broiler quails was \( y = 0.0145x + 8.0157 \), exhibiting a low coefficient of determination (\( R^2 \)) of 0.1402. In conclusion, the study identified a strong correlation between body weight and egg weight for Padjadjaran layer quails, while a weak correlation was observed for Padjadjaran broiler quails. Furthermore, the regression equation for predicting egg weight based on body weight is deemed reliable for Padjadjaran layer quails but not applicable to broiler quails, as the low determination value suggests that the regression model for broiler quails is insufficient for such predictions.

Abstract

Corchorus aestuans plants have potential as animal feed. Giving banana peel POC is an effort to increase the productivity of this plant. Knowing the effect of various doses of banana peel POC on the growth and productivity of Corchorus aestuans plants is the purpose of this study. The Completely Randomized Design method was used with five treatments namely P1 = 0 ml, P2 = 100 ml, P3 = 200 ml, P4 = 300 ml, P5 = 400 ml was tested on March 21 to May 30 at the Faculty of Animal Husbandry, Universitas Padjadjaran. Each treatment was repeated four times, resulting in twenty experimental materials. Plant height, number of leaves, fresh weight, dry weight, stem leaf ratio, and shoot root ratio were some of the parameters recorded. After the data were analyzed for variance, Duncan Multiple Range Test (DMRT) was conducted. The results showed that although fresh weight was significantly affected by banana peel POC (P < 0.05), plant height, number of leaves, dry weight, stem leaf ratio, and shoot root ratio were not significantly affected (P > 0.05). The 100 ml dose was the most effective dose (P2).

Abstract

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.

Abstract

Livestock waste is one of the factors that must be considered in livestock farming, as it can cause environmental pollution. Quail feces, a type of livestock waste, generally has a low carbon-to-nitrogen ratio, necessitating the supplementation of carbon source from rice straw. Rice straw, which contains high fiber content, is often discarded or burned and has not been utilized by farmers, even though it is suitable for processing into solid or liquid organic fertilizer (POC). Because of the substantial changes in temperature and microbial composition that occur during the composting process, initial breakdown is critical. Using native microbes from quail feces, this study aims to ascertain the impact of the C/N ratio of a mixture of quail feces and rice straw on temperature changes, total microbial count (bacteria, fungi, and actinomycetes), and the content of organic C and total N during the initial decomposition process. This research employed an experimental method with four treatments of C/N ratio mixtures of quail feces and rice straw: 20, 25, 30, and 35. The observed variables included temperature changes, total microbial count (bacteria, fungi, and actinomycetes), and the content of organic C and total N over 14 days of initial decomposition. The best decomposition process was achieved with a C/N ratio of 20, the highest temperature change (thermophilic phase on the second day and a maximum temperature of 65°C), and total counts of bacteria, fungi, and actinomycetes of 9.6 x 1011 cfu/mg, 2.7 x 104 cfu/mg, and 5.6 x 106 cfu/mg, respectively. The organic C content was 37.62%, and the total N content was 3.11% (C/N 12.09).

Abstract

Penggunaan bahan pengikat sintetik pada pakan pelet dianggap mahal, sehingga mendorong pencarian alternatif yang lebih ekonomis dan mudah didapat dari sumber alami yang melimpah di Indonesia. Tepung sagu, tepung tapioka, dan molase diidentifikasi sebagai bahan alami yang kaya akan pati dan energi. Penelitian ini bertujuan untuk mengevaluasi kualitas pakan pelet dengan menggunakan bahan pengikat yang berbeda berdasarkan sifat fisik dan nilai gizinya. Rancangan Acak Lengkap (RAL) dengan empat perlakuan: PO: Pelet broiler finisher komersial, P1: Ransum broiler finisher + tepung tapioka 2%, P2: Ransum broiler finisher+ 2% molase, dan P3: Ransum broiler finisher+ 2% tepung sagu , masing-masing dengan 10 ulangan. Variabel yang diamati meliputi analisis proksimat untuk menilai kandungan protein kasar dan energi metabolisme pelet, serta uji kualitas fisik seperti berat isi, gaya putus, berat jenis, dan kepadatan tumpukan. Data uji kualitas fisik dianalisis menggunakan Analysis of Variance (ANOVA) dan Duncan’s Multiple Range Test (DMRT). Penambahan bahan pengikat P1 (tepung tapioka 2%) dan P3 (tepung sagu 2%) tidak memberikan perbedaan sifat fisik seperti berat badan hulk, gaya putus, berat jenis, dan berat jenis tumpukan pelet (P<0,05). Sedangkan P2 (2% molase) menunjukkan perbedaan nyata pada berat jenis dan kepadatan tumpukan (P<0,05), namun tidak berbeda nyata pada berat jenis dan gaya putus. Kesimpulannya, penggunaan tepung tapioka 2% sebagai bahan pengikat terbukti merupakan perlakuan yang optimal untuk mencapai mutu fisik dan nilai gizi terbaik, dilihat dari berat isi, kekuatan putus, berat jenis, dan kepadatan tumpukan pelet.

Abstract

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.
