The bi-guanide metformin is used to treat noninsulin dependent diabetes in obese patients. In addition to having antihyperglycemic effects, metformin is also anorectic and reduces BW. These studies were performed to determine if metformin possesses similar properties in chickens. Metformin-HCl was administered to 14-day-old broiler chickens at either 300 or 600 mg/kg per day in the drinking wat...

Cryptosporidiosis, caused by the apicomplexan parasite Cryptosporidium parvum, has become a well-recognized diarrheal disease of humans and other mammals throughout the world. No approved parasite-specific drugs, vaccines, or immunotherapies for control of the disease are currently available, although passive immunization with C. parvum-specific antibodies has some efficacy in immunocompromised...

introduction under commercial conditions broiler are feed restricted during rearing to limit growth rate. this quantitative restriction of feed intake aims at avoiding rapid growth and high body weights, which are associated with pathological conditions, such as ascites, lameness, and mortality. feed restriction (fr) in breeder layer hens was rarely and fr used for poor reproductive results and...

A detailed electron spin resonance (ESR) study of spin-labeled-oriented multilayers of L.-dipalmitoylphosphatidylcholine (DPPC) water systems for low water content (2-10% by weight) is reported with the purpose of characterizing the dynamical and structural properties of model membrane systems. Emphasis is placed on the value of combining such experiments with detailed simulations based on curr...

one experiment was conducted in order to evaluate four levels of macaroni waste including: 0, 10, 20 and 30 percentage in growing turkey feed in a completely randomized design (crd) with 120 local turkey including 3 replicates in 12 pens. during the experiment (3-8 weeks), turkeys received feed and water of free access. weight gain, feed consumption and feed efficiency were measured weekly. dif...
