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...

The effect of starvation and re-feeding was investigated on growth, hematology and biochemical parameters in juvenile Persian sturgeon (Acipenser persicus). Three hundred and seventyfive fish (108±0.63 g) were divided into five feeding groups. The control group (C) was fed to satiation three times a day during the experiment. The four groups were starved for 1 (W1), 2 (W2), 3 (W3), and 4 (W4) w...

This study examines factors affecting weaning pattern of mothers residing in Shiraz(Iran).A cohort of 329 mothers who gave birth at the 14 maternity clinics of shiraz during two consecutive weeks in 1996 were selected randomly.mothers were visited 11 times at home during 2 years post delivery and their breast feeding performance and its associatef factors were examined closely.mother,s knowledg...

Feeding is the set of behaviors whereby organisms acquire and process the energy required for survival and reproduction. Thus, feeding system morphology is presumably subject to selection to maintain or improve feeding performance. Relationships among feeding system morphology, feeding behavior, and diet not only explain the morphological diversity of extant primates, but can also be used to re...

Body size and feeding mode are two fundamental characteristics that determine foraging performance and ecological niche. As the smallest obligate lunge filter feeders, minke whales represent an ideal system for studying the physical and energetic limits of filter feeding in endotherms. We used multi-sensor suction cup tags to quantify the feeding performance of Antarctic minke whales. Foraging ...

OBJECTIVES To develop a composite index to describe the overall breast-feeding performance of infants<6 months of age; and, using this index, to identify the factors associated with poor breast-feeding practices and the association between breast-feeding and infant morbidity. DESIGN, SETTING AND SUBJECTS The 2003 Demographic and Health Survey was a multi-stage cluster sample survey of 4320 ho...
