Enhancing the Production Performance and Nutrient Utilization of Laying Hens by Augmenting Energy, Phosphorous and Calcium Deficient Diets with Fungal Phytase (Trichoderma reesei) Supplementation
No full textA ten-week trial was conducted to evaluate the enhancement of production performance and nutrient utilization of laying hens through augmenting energy, phosphorous, and calcium deficient diets with fungal phytase (Trichoderma reesei) supplementation. 720 Hy-line Brown hens aged 28 weeks were randomly divided into 5 groups; each group had 8 replicates of 18 hens. Five experimental diets were prepared and fed to corresponding groups. A positive control (PC) diet contained 3.50% of calcium (Ca), 0.32% of non-phytate phosphorus (NPP), and apparent metabolic energy (AME) of 11.29MJ/kg, while a negative control (NC) diet contained 3.30% of Ca, 0.12% of NPP, and lower AME of 300 kJ/kg. The other three diets were supplemented with 250 FTU/kg phytase (PHY-250), 1000 FTU/kg phytase (PHY-1000), and 2000 FTU/kg phytase (PHY-2000) in addition to a regular NC diet. Results indicated that the positive control (PC) diet group had higher body weight gain, egg weight, and average daily feed intake. However, laying rate, egg mass, and FCR were most improved in the PHY-2000 group, followed by the PHY-1000 and PHY-250 groups (p < 0.05). Improved yolk color was most notable in laying hens fed the diet with PHY-1000 as opposed to the PC and NC groups (p < 0.05), but no overall difference was found among all of the phytase treated groups. The apparent availability of dry matter, energy, phosphorus, and phytate P was significantly higher in the PHY-2000 group than in the PC and NC groups (p < 0.05). Compared to the PC group, nitrogen retention was significantly higher in the PHY-1000 group, while calcium availability was higher in the PHY-250 group. The results suggested that the addition of phytase to diets with low P, Ca, and AME improved laying performance and apparent availability of dietary nutrients. Thus, it was concluded that the laying hen diet could be supplemented with 1000–2000 FTU/kg phytase for improving laying production and nutrient availability and mitigating the negative impact of reduced nutrient density in laying hen diets
PEMANFAATAN LIMBAH PERTANIAN DAN FESES UNTUK MEDIA HIDUP MAGGOT (Hermetia illucens) SEBAGAI PAKAN SUMBERPROTEIN HEWANI DI PETERNAKAN ARJUNA
No full textAgricultural waste and livestock manure that are not properly utilized can cause environmental pollution. This community service aims to reduce environmental pollution through the treatment of agricultural waste and fermented manure to be used as maggot growth media at Arjuna Farm. Maggots are a source of animal protein with good nutritional value, containing 45-50% crude protein. The production of maggots from livestock and agricultural waste can serve as a source of nutrition for livestock. The community service methods include fermenting agricultural waste and manure to create maggot growth media, maggot cultivation training, and the production of dry maggot products that can be used as a source of animal protein feed for poultry. This program also contributes to increasing the income of Arjuna Farm through the produced dry maggot products. It is hoped that through this community service, farmers can access appropriate technology for processing fecal and agricultural waste using fermentation technology to produce a good growth medium for maggots. The results of this service have an impact on environmental preservation and reducing the negative effects of agricultural and fecal waste, as well as contributing to improving their economic welfare. The observation percentages after evaluation at Arjuna Farm were not significantly different from the expected results, with an average of 74% out of 92% in terms of waste processing and farmers' income.Limbah pertanian dan feses ternak yang tidak termanfaatkan dengan baik dapat menyebabkan pencemaran lingkungan. Pengabdian ini bertujuan untuk mengurangi pencemaran lingkungan melalui pengolahan limbah pertanian dan feses yang difermentasi sebagai bahan media hidup maggot di Peternakan Arjuna. Maggot merupakan sumber protein hewani yang memiliki nilai nutrisi yang baik yaitu protein kasar 45-50%. Produksi maggot yang dihasilkan dari limbah peternakan dan pertanian dapat menjadi sumber nutrisi bagi ternak. Metode pengabdian yang digunakan meliputi fermentasi limbah pertanian dan feses menjadi media hidup maggot, pelatihan budidaya maggot, serta pembuatan produk dry maggot yang dapat dijadikan sebagai pakan sumber protein hewani bagi ternak unggas. Program ini turut meningkatkan pendapatan Peternakan Arjuna melalui produk dry maggot yang dihasilkan. Diharapkan melalui pengabdian ini peternak dapat mengakses teknologi tepat berupa pengolahan limbah feses dan limbah pertanian menggunakan teknologi fermentasi untuk menghasilkan media tumbuh yang baik untuk maggot. Hasil pengabdian ini berdampak terhadap pelestarian lingkungan dan pengurangan dampak negatif dari limbah pertanian dan feses, serta turut meningkatkan kesejahteraan ekonomi mereka. Hasil persentase pengamatan setelah dilakukan evaluasi ke Peternakan Arjuna tidak berbeda jauh dengan persentase hasil yang diharapkan, yaitu didapatkan rata-rata 74% dari 92% pada aspek pengolahan limbah dan pendapatan peternak
Innovative Use of Endogenous Enzymes to Enhance Silage Chemical Quality of Corn Straw for Buffalo (Bubalusbubalis) Feed in Samosir Island
No full textOn Samosir Island, there is an annual shortage of buffalo feed during the dry season. However, this feed shortage has caused farmers to scramble to find substitute feed. Still, it has also caused stress in the buffalo, which has led to the emergence of Haemorrhagic septicemia (HS), as Samosir is an endemic area (HS). Beginning in 2024, corn cultivation began to be widely practiced on the island of Samosir, which generates a significant amount of waste such as corn straw. This research focuses on preparing feed for buffalo (Bubalus bubalis) using fermented corn straw, with the fermentation process utilizing endogenous enzymes derived from rumen fermentation (EERF). It was obtained from fermented 100- day buffalo rumen, where the buffalo rumen comes from buffalo that consume corn straw. This study used a completely randomized design, a 3×3factorial with three replications. Factor I was various doses of EERF(2%, 4%,6%),and Factor II was different fermentation times(5d,10d, 15d).Parameters that were observed in this study were chemical quality: Dry Matter (DM), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Crude Protein (CP), and pH. Previously, isolation on EERF was carried out to identify the dominant fiber-degrading colonies, as they produce enzymes. Analysis of the potential of corn straw for buffalo feed was conducted by calculating corn straw production from the corn harvest area on Samosir Island. The result of this study is that corn straw fermentation using endogenous enzymes improves the chemical quality of silage, such as DM increasing from 38.59 to 46.17, NDF from 46.23 to 40.48, ADF from 30.53 to 24.21, CP from 9.25 to 9.86, and pH from 5.15 to 4.76. Through this improvement in nutritional quality, the dietary needs of buffaloes are met. This corn straw is sufficient for 9,565,101 buffaloes. Since corn cultivation has become intensive, there is a tendency of HS cases to decrease, with only 6 instances of HS in 2024 and 13 cases up to June 2025, while in 2023 there were 202 cases
