Research ArticleOpen accessEvery word in the titleEvaluation of Nutrient Composition in Feed Supplements Used by Communal Beef Farmers During the Dry Season in Ga-Matlala, Limpopo ProvinceThapelo Rosina Monkwe, Masibonge Gxasheka, Busisiwe GunyaThis study assessed the nutrient composition of feed supplements commonly used by communal beef cattle farmers during the dry season in Limpopo Province of South Africa. A total of seven feed supplements, such as lucerne hay, maize stover, salt licks, calf grower, calf milk replacer, cattle feed pellets, and soybean meal, were sampled and analysed for proximate composition and mineral … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 16 Mar 2026 · 1,651 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiosynthesis and Evaluation of Zinc, Copper, and Methionine Feed Supplements Using Saccharomyces cerevisiae on Duck Performance in Minimal Water SystemsHendi Setiyatwan, Muhammad Rifqi IsmirajOptimizing duck performance under minimal water conditions is essential for sustainable poultry farming. Biosynthesizing essential feed supplements like Zinc (Zn), Copper (Cu), and methionine using Saccharomyces cerevisiae presents a promising method to enhance growth and meat quality. This study developed a biosynthesis method for Zn, Cu, and methionine supplements using S. cerevisiae and evaluated their effects on duck performance. In … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 11 Feb 2025 · 4,405 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIn 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 PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of the Texas Feed Yard Workforce: Survey of Stockperson Attitudes and Perceptions towards Euthanasia, Animal Care and Employee ValueEmily E. Ridge, Ron Gill, Courtney L. DaigleA survey was administered to Texas cattle feedyard employees (n =111) from 31 different operations measuring stockperson perception, job satisfaction and socioeconomic status using Likert statements and multiple-choice questions. Differences among employment roles (manager, pen rider, processor (those who vaccinate and implant incoming calves), doctor (non-veterinarians)) were evaluated using a Kruskal-Wallis test followed by a Multiple Comparison procedure.

Research ArticleOpen accessIn the keywordsNutrient Digestibility and Gas Production of Some Tropical Feeds Used in Ruminant Diets Estimated by the in vivo and in vitro Gas Production TechniquesPaya Hamid, Taghizadeh Akbar, Janmohammadi Hossein, Moghadam Gholam AliSome feedstuffs which used in ruminants diet (corn grain, soybean meal, wheat bran and alfalfa) were analyzed for chemical composition, apparent in vivo nutrient digestibility, in vitro fermentation gas production and metabolizable energy. Chemical composition of test feeds differed in nutrient contents. Initially apparent in vivo digestibility of alfalfa nutrients were obtained then digestibility of nutrients for the other test … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeta Analysis of Growth Performance of Broilers in Response to Dietary Cassava Leaf Meal InterventionChristian Anayo Mbajiorgu, Ifeanyi Princewill OgbuewuThe use of Cassava Leaf Meal (CLM) in broiler diets has gained attention due to its high crude protein content (24-35%) and other valuable nutrients. Therefore, the objective of this meta-analysis was to assess the impact of diets with and without CLM on broiler growth performance. Search performed on four bibliographic databases produced 584 articles of which 11 were used … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 30 Sep 2026 · 578 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Dietary Feed Additives on Productivity in Broiler ChickensGaukhar Moldakhmetova, Zhanar Kussainova, Shohkan Alpeisov et al.Proper feeding is a key aspect of poultry farming; a balanced diet supports flock health, prevents infectious diseases, and enhances product quality. A relevant issue in poultry farming is the use of various probiotics and feed additives that positively impact gut health and its microbiota, which in turn promotes the growth and development of birds. In a scientific-farm experiment, the … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 4 Dec 2025 · 2,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Breeding Qualities of Kazakh White-Headed Bulls by Testing Their ProductivityAruzhan Nugmanova, Aliya Akhmetaliyeva, Yedige Nassambayev et al.The purpose of the study was to quantify the breeding qualities of Kazakh White-Headed bulls by assessing their productivity metrics. The primary objectives were to analyze live weight dynamics, daily growth rates, feed conversion efficiency, and morphological meat quality and to employ "A" complex indices for evaluating the breeding potential. The study observed bulls aged 8-15 months at the Khafiza … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 26 Jul 2024 · 5,407 accessesView PDFCite
