Chick feeding test: a simple system to detect ciguatoxin.
Chick poisoning induced by oral administration of toxic fish tissues or extracts gave rise to internal hypersalivation, decrease in weight and acute motor ataxia. Detoxification was low and repeated administration therefore led to toxin accumulation. Response of the chicken to liver feeding was roughly quantitative; so liver, which is the most potential toxic tissue, may be used for a preventiv...
متن کاملA broiler chick bioassay for measuring the feeding value of wheat and barley in complete diets.
Energy is an important component of poultry feed and is derived principally from cereal grains. Unfortunately, all of the chemical energy is not available to the bird, and biological assays must be used to determine the digestible energy value of a cereal grain. The bioassay described uses four pens of six male broiler chicks, complete diets containing 80% of a test cereal grain (with or withou...
متن کاملOverdrive suppression of spontaneously beating chick heart cell aggregates: experiment and theory.
In spontaneously beating chick heart cell aggregates, sustained periodic stimulation at a rate faster than the intrinsic frequency is generally followed by a transient slowing of the automatic rhythm called "overdrive suppression." We characterize the qualitative aspects of overdrive suppression using three sets of experimental protocols: 1) stimulation at a fixed frequency with various numbers...
متن کاملChanges in free amino acid and monoamine concentrations in the chick brain associated with feeding behavior
Domesticated chicks are precocial and therefore have relatively well-developed feeding behavior. The role of hypothalamic neuropeptides in food-intake regulation in chicks has been reported for decades. However, we hypothesized that nutrients and their metabolites in the brain may be involved in food intake in chicks because these animals exhibit a very frequent feeding pattern. Therefore, the ...
متن کاملThe Design and Experiment of the Track-Type Equipment for Feeding Dairy Cows
As one of the effective ways of reducing the cost and increase the revenue, feeding dairy cows with individual precision in quantity could further develop the production potential of high-yield dairy cows and improve the milk yield of every dairy cow. Therefore, based on three kinds of technologies of radio frequency identification technology, wireless transmission technology and infrared techn...
