Clostridium Butyricum Can Be Used as a Potential Alternative for the Antibiotic in Cherry Valley Ducks
The present study was conducted to investigate the effects of Clostridium butyricum inclusion, as an alternative for antibiotic, on growth performance, immunity and oxidative status of Cherry Valley ducks. 240 1-day-old Cherry Valley ducks were randomly allocated to 2 groups with 6 replicates of 20ducks, receiving a basal diet supplemented with zinc bacitracin (40 mg/kg diet, Control group) or ...
متن کاملEffect of age on the pathogenesis of duck tembusu virus in Cherry Valley ducks
The effect of host age on the outcome of duck tembusu virus (DTMUV) infection was studied in ducks. Three groups of Cherry Valley ducks at 1, 3, and 7 weeks of age were intramuscularly infected with DTMUV to systematically observe the clinical symptoms, pathological changes, tissue viral loads, and immune responses. Severe clinical symptoms and neurological dysfunction were observed in 1-week-o...
متن کاملComparison of growth models between artificial neural networks and nonlinear regression analysis in Cherry Valley ducks
Currently, artificial neural networks (ANN) are being applied to livestock production as alternatives to regression analysis for forecasting egg prices [1, 2], selecting the feed mix in the feed industry [3], and predicting the amino acid composition of feed ingredients [4, 5]. The advantages of ANN have been reported. Unlike regression analyses, ANN do not require that a mathematical model be ...
متن کاملCherry Valley Ducks Mitochondrial Antiviral-Signaling Protein-Mediated Signaling Pathway and Antiviral Activity Research
Mitochondrial antiviral-signaling protein (MAVS), an adaptor protein of retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs)-mediated signal pathway, is involved in innate immunity. In this study, Cherry Valley duck MAVS (duMAVS) was cloned from the spleen and analyzed. duMAVS was determined to have a caspase activation and recruitment domain at N-terminal, followed by a proline-rich do...
متن کاملRequirement of the laying hen for apparent fecal digestible lysine.
A study was conducted to determine the requirement for lysine of a White Leghorn strain of hens with a body weight of approximately 1,600 g. Before starting the experiment, apparent fecal digestibility of amino acids of the basal diet was determined in an in vivo digestibility trial with six individually housed hens. The basal diet used was based on corn and soybean meal and contained 0.65% tot...
