Research ArticleOpen accessIn the abstractEconomic Feasibility and Growth Performance of Holstein Friesian Calves Fed Whey-Dangke Fortified Green Calf StarterZyahrul Ramadan, Renny Fatmyah Utamy, Hasbi Hasbi et al.This research evaluated the impact of feeding green calf starter fortified with whey-dangke on Holstein Friesian dairy calves' economic feasibility, growth performance, and health parameters. Experimental diets were applied to 18 Holstein Friesian dairy calves using a randomized complete factorial design with two factors: type of calf starter and level fortification of whey-dangke. The results showed that calves fed different … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 9 Jul 2025 · 3,296 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSemen Quality and Artificial Insemination Efficacy Using Sericin-Silica-Phosphate-CuO Hydrogel in Thin-tailed SheepEnike Dwi Kusumawati, I Wayan Karyasa, Duran Corebima Aloysius et al.Artificial Insemination (AI) in livestock is increasingly demanded because it greatly affects the productivity and quality of livestock. AI should be supported by advanced material chemistry, especially organic-inorganic hybrid biomaterials. We aimed to produce a prototype of renewable advanced biomaterial technology in the form of Sericin-Silica-Phosphate (SER-SI-PO) hydrogel reinforced with Copper Nanoparticles (CuNPs) and its application in AI. The testing … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 10 Jun 2025 · 3,851 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpact of Lighting Durations on Production, Quality, and Fungal Contamination in Green FodderSuci Wulandari, Adib Norma Respati, Satria Budi Kusuma et al.This study aimed to identify hydroponic fodder seeds with optimal production and chemical quality and to determine the fungal species contaminating the green fodder produced. This study used a 2´5 Factorial Completely Randomized Design pattern, with 2 replications. Factor I consisted of two lighting treatments: (1) 12 hours of natural sunlight and (2)24 h of light (natural sunlight followed by … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 3 Jun 2025 · 4,792 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimum Fertilization Technology to Improve Crop Productivity of Stevia (Stevia rebaudiana Bertoni)Mohammad Cholid, Sesanti Basuki, Budi Hariyono et al.Stevia leaves have the potential to be developed as a natural sweetener, a companion to cane sugar, especially for those who need low-calorie intake. Increasing the productivity of stevia plants is approached by increasing plant biomass accumulation through balanced nitrogen fertilization. This research aims to obtain optimal nitrogen fertilization in the cultivation of stevia plants in which the nitrogen derived … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 22 Nov 2024 · 5,111 accessesView PDF Cite

Research ArticleOpen accessIn the abstractParticle Size Determination in Rice Bran Testing with Various Levels of Rice Husks Using Ultrasonic WavesUrip Rosani, Iman Hernaman, Rahmat Hidayat, Darmawan HidayatThe principle of ultrasonic waves in detecting materials is based on their physical properties. The size of particles has an impact on various aspects of their composition and function. The limited information that reports the particle size of RH-contaminated RB samples tested using ultrasonic waves is the basis for this study. This study aims to determine the optimal sample particle … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 6 Nov 2024 · 4,357 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuality of Sperm Simmental Bulls and Success of Artificial Insemination with the Addition of Nanocalcium Phosphate in Tris Aminomethane Egg Yolk Diluent Using Semen Storage Ampoules from Nanocalcium Silicophosphate BiomaterialsEnike Dwi Kusumawati, I Wayan Karyasa, Yogi Pratama Putra et al.Success in Artificial Insemination (AI) is largely determined by the quality of the stored semen, therefore storage devices, especially straws or ampoules, are an important part that cannot be separated from the overall semen cryopreservation technology. Making a prototype of semen storage ampoules from nanocalcium silicophosphate biomaterials is based on the need for straws or ampoules. Semen storage in spermatozoa … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 28 May 2024 · 5,211 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn Sacco and in vitro Evaluation of Heating and Formaldehyde Treated Protein FeedAnnisa Rosmalia, Idat Galih Permana, Despal, Toto ToharmatMassive protein conversion into ammonia in the Rumen (RDP) should be avoided to prevent protein quality deterioration. Heating and formaldehyde treatments are commonly used to decrease Rumen-Degradable Protein (RDP), but it rarely used to protect local feed. We aimed to compare the effectiveness of heating and formaldehyde treatments in decreasing the RDP of local feed. The use of fistulated cattle, … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 12 Feb 2024 · 6,253 accessesView PDF Cite
