Research ArticleOpen accessEvery word in the titleCytotoxicity Evaluation of Curcumin-FITC Conjugates in Granulosa Cells Isolated from Ovarian Follicles of Kampung Chicken (Gallus gallus domesticus)Sukarman Hadi Jaya Putra, Mansur S, UmarudinLinking curcumin to fluorescein isothiocyanate (FITC) results in a hybrid fluorescent marker (curcumin-FITC) that exhibits improved stability and sensitivity in detection. This study sought to evaluate the biological safety and cytotoxic effects of curcumin-FITC on granulosa cells obtained from ovarian follicles (2-5 mm, F1-F4 stage) of Kampung chickens. Following fluorescent labeling with different concentrations of curcumin-FITC (0-100 μg/mL), cell viability … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 14 May 2026 · 1,497 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Dietary Isoleucine Supplementation on the Growth Performance, Carcass Characteristics and Ileal Morphology of Native ChickensCharles Venirius Lisnahan, Oktovianus Rafael Nahak, Lukas PardosiThe roles of isoleucine in the protein synthesis, metabolisms, and growth of chicken have been widely reported. However, its effect on native chicken has not been previously reported. In this work, we reported the effects of dietary isoleucine supplementation on growth performance, carcass characteristics, and ileal morphology in native chickens during the grower phase (6-12 weeks). Two hundred native chickens … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 21 Jun 2025 · 2,940 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGrowth Performance and Duodenal Morphometry of 1-6 Week Old Kampung Chickens Supplemented With L-LeucineCharles Venirius Lisnahan, Steffanie Merlin Clyricia Noach, Lukas Pardosi, Theresia Nur Indah KoniThis study evaluated the effects of dietary L-leucine supplementation on growth performance and duodenal morphometry of Kampung chickens during the starter phase (1–6 weeks). A total of 600 one-week-old Kampung chickens were randomly assigned to five dietary treatments with six replicates of 20 birds each in a completely randomized design. The treatments consisted of a basal diet without L-leucine (T0) … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 11 Sep 2026 · 904 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDietary Protein and Energy Levels at 3200 m Altitude for Slow-Growing ChickensMariela Ketty Meza-Morveli, Liz Beatriz Chino-Velasquez, Jesús Camero DeLaCuba et al.The extent to which energy and protein (CP) levels can be reduced without impacting productivity in slow-growing chickens remains undetermined. The treatments were conducted to evaluate the effect of dietary CP (17.5, 19, and 20.5%) and energy (2850-2950 kcal ME/kg) on slow-growing chickens using an ideal protein concept at a high altitude (3200 m). We used a total of 144 … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 20 Dec 2024 · 5,275 accessesView PDFCite

This study focused on the prevalence of Salmonellae in imported … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 2 · 28 May 2020 · 6,986 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExogenous Progesterone for Offspring Sex Ratio Manipulation in Arabic Chickens (Gallus turcicus) Leading to Increasing Female Chicks ProportionIswati, Muhammad Halim Natsir, Gatot Ciptadi, Trinil SusilawatiFemale birds of egg-laying hens are more valuable than males, because males bird have no commercial value. The opportunity to manipulate offspring sex ratio in poultry has been observed in female birds; hence, female birds have heterogametic ZW chromosomes. High progesterone concentration 2-5 h before ovulation is thought to affect the segregation of female sex chromosomes as the basis for … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 17 Feb 2021 · 7,500 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermination of the Mutagenicity of 2-aminoanthracene Using Chicken Hepatic S-9 FractionVladimir A. Chistyakov, Alexander V. Usatov, Aleksander I. Klimenko et al.The abundance of potential genotoxins makes it necessary to improve microbial test systems that allow to identify these substances quickly. At the same time, the methodology of metabolic activation of promutagens in vitro is very important. Microsomal preparations of rodents, which are generally used for that, have significant disadvantages associated with the potential health risks of the inducers of the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 16 Nov 2018 · 7,192 accessesView PDFCite
