Antibiotics improve health and productive performance of pigs. There is increasing evidence that other dietary ingredients may provide similar, but probably not identical, benefits. A properly prepared immune egg product, spray-dried plasma, or a high level of dietary zinc can provide protection against enteric infection in young pigs. Spray-dried plasma also increases growth rate dramatically,...

A meta-analysis was conducted to determine the effects of different types oligosaccharides (OS) on egg quality, intestinal profile, nutrient digestibility, and immunity laying hens. dataset constructed from articles published between 2006 2023 via a literature search using several keywords related hens’ performance. After careful evaluation, final developed 25 in vivo studies comprising 165 com...

in this experiment, the influence of prebiotic and probiotic supplementation in the broiler breeder diets on body weight, mortality, feed intake, egg production, hatchability and humoral immunity response was investigated. a total number of 13140 female and 1260 male breeders (cobb 500) with 26 wks of age were allocated to three treatments with six replicates (800 birds each replicate). breeder...

Plant cell wall polysaccharides are notoriously difficult to analyze, and most methods require expensive equipment, skilled operators, and large amounts of purified material. Here, we describe a simple method for gaining detailed polysaccharide structural information, including resolution of structural isomers. For polysaccharide analysis by gel electrophoresis (PACE), plant cell wall material ...

in view of the increase in saccharomyces cerevisiae mannan content, the culture condition for s.cerevisiae were optimized in this study. the influence of culture condition such as original ph, inoculum size, and temperature on mannan production were evaluated using response surface methodology. the mathematical model was established by the quadratic rotary combination design. with the order of ...
