an experiment was conducted to study the effect on performance of silkworm bombyx mori l., when fed by leaves of different mulberry varieties a crd design with 12 tratments (including kamasari, kaeiryo ichinose, kaeerizhotezomigaeeshi, tachibana, ichinose, chekemaoha, yukishinogi, shin ichinose, wasemidori, roso, kenmochi, as well as some local varieties in 4 replications. the larvae were reare...

backgrounds: optimization of microbial compositions and load in live food during the process of bioencapsulation is one of the most important concerns in aquaculture, as it can promote the growth and feeding parameters of fish larvae. objectives: the aim of this study was to determine the growth and feeding performance of persian sturgeon larvae fed with bioencapsulated d. magna with saccharomy...

For most vertebrates, locomotion is a fundamental component of prey capture. Despite this ubiquitous link, few studies have quantified the integration of these complex systems. Several variables related to locomotor performance, including maximum speed, acceleration, deceleration, maneuverability, accuracy, and approach stability, likely influence feeding performance in vertebrates. The relativ...

the aim of this study was to investigate the processing methods of sorghum grain and diet formulation on performance and nutrients digestibility in broilers. three hundred and twenty chicks at eight day of age were allotted into eight groups of four replicate with ten chicks per replicate. this research was conducted as completely randomized design arranged in a 2 × 2 × 2 factorial experiment u...

The New World cichlids Petenia splendida and Caquetaia spp. possess extraordinarily protrusible jaws. We investigated the feeding behavior of extreme (here defined as greater than 30% head length) and modest jaw-protruding Neotropical cichlids by comparing feeding kinematics, cranial morphology, and feeding performance. Digital high-speed video (500 fps) of P. splendida, C. spectabile, and Astr...
