T production of fish feed additives for the aquaculture industry is a thriving sector in China. These natural substances are being used for several purposes including the enhancement of the immune systems of farmed fish, promoting growth, attaining the desired flesh and skin pigmentation, as well as improving the organolepctic properties of the farmed product. At the same time, the use of such ...
A total number of 48 male growing New Zealand rabbits were used to study the effect of two different levels of ration energy supplemented with mixture of Lupinus albus L, Trigonella foenum-graecum L and Cassia senna L as feed additives. Rabbits were classified into four equal groups (G1-G4). The 1 and 3 groups received basal ration with 100 % and 90 % energy requirement and served as first and ...
Three feed additives were tested to improve the growth and health of pigs chronically challenged with aflatoxin (AF) and deoxynivalenol (DON). Gilts (n = 225, 8.8 ± 0.4 kg) were allotted to five treatments: CON (uncontaminated control); MT (contaminated with 150 µg/kg AF and 1100 µg/kg DON); A (MT + a clay additive); B (MT + a clay and dried yeast additive); and C (MT + a clay and yeast culture...
The in vitro affinity and adsorption capacity of a humic acid, oxihumate, for aflatoxin B1 (AFB1) was evaluated, utilizing Langmuir and Freundlich adsorption isotherms. Oxihumate showed a high in vitro affinity for AFB1. The Freundlich isotherm fitted the data better than the Langmuir isotherm, and binding capacities of 10.3, 7.4, and 11.9 mg of AFB1/g of oxihumate at pH 3, 5, and 7, respective...
The intestinal environment plays a critical role in maintaining swine health. Many factors such as diet, microbiota, and host intestinal immune response influence the intestinal environment. Intestinal alkaline phosphatase (IAP) is an important apical brush border enzyme that is influenced by these factors. IAP dephosphorylates bacterial lipopolysaccharides (LPS), unmethylated cytosine-guanosin...
Foodborne diseases caused by enterohemorrhagic Escherichia coli, Salmonella, and Campylobacter species are of public health and economic significance. Shedding of these pathogens during production and slaughter are risks for contamination of products for human consumption. Consequently, strategies are sought to prevent or reduce the carriage of these pathogens in food animals before slaughter. ...
The effects of antibiotic, probiotic, and prebiotic as dietary feed additives on carcass composition as well as Salmonella counts and its serotypes in droppings and intestine of broiler chickens on days 1, 28, and 56 of experiment were investigated. Dietary treatments were control diet (basal diet without additives), OXYT diet (basal diet with 600 ppm of the antibiotic oxytetracycline), GRO-UP ...
Antibiotic growth promoters (AGPs) have been used as feed additives to improve average body weight gain and feed efficiency in food animals for more than 5 decades. However, there is a worldwide trend to limit AGP use to protect food safety and public health, which raises an urgent need to discover effective alternatives to AGPs. The growth-promoting effect of AGPs has been shown to be highly c...
Probiotics act positively on rumen feed digestion and ruminant production as feed additive, these additives are diverse and exerting their action through different mechanisms. This review gives an overview of the probiotics feed additive and summarizes the current status of lactic acid bacteria, yeast and Bacillus which are the most common used feed additive to improve milk performance and heal...
Nicarbazin is a non-ionophoric synthetic complex composed of an equimolar amount of 4,4’dinitrocarbanilide (DNC) and 2-hydroxy-4,6-dimethylpyrimidine (HDP) that is authorised as a coccidiostat feed additive for use in chickens for fattening at a maximum concentration of 50 mg/kg in complete feed as a combination product with narasin (List of authorised additives in feedingstuffs (2004/C 50/01))...
