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...
Appropriate infant and young child feeding could reduce morbidity and mortality and could improve cognitive development of children. However, nationwide data on exclusive breastfeeding and complementary feeding status in China are scarce. The aim of this study was to assess current exclusive breastfeeding and complementary feeding status in China. A national representative survey (Chinese Natio...
We have examined the role of the octopamine-containing buccal OC interneuron in the fictive feeding rhythm generated by depolarizing a modulatory interneuron, SO, in the isolated central nervous system (CNS) of Lymnaea stagnalis. Before stimulating the SO, the initial fictive feeding rate was 2.0+/-0.37 bites/min (mean+/-S.E.). When the SO was stimulated, the fictive feeding rate more than doub...
Feeding frequency and stocking density are important factors affecting growth and maturation of cultured fishes. The aims of this investigation were to determine the effects of stocking density (10, 20, 30 and 40 fish per aquarium) and feeding frequency (2, 3 and 4 times per day) on growth parameters and hematocrit of the Rutilus rutilus caspicus. The experiment was continued for 45 days in two...
The predatory beetle Cybocephalus fodori minor has recently been reported in Iran. Also few studies have been reported on life cycle of Cybocephalus beetles, especially on that of C. f. minor. Thus, the life cycle and feeding rate of this predatory beetle was studied on pistachio oyster shell scale, Lepidosaphes pistaciae under laboratory conditions (temperature: 25 ± 2 °c relative humidity: 6...
Breast Feeding and Weaning Practices have a major effect on short term and long term nutritional status of infants. An attempt was made to find out the pattern of infant feeding practices in Thar Desert of Rajasthan so as to know the community perceptions existing in this area. Data were collected from 434 young women belonging to rural house-holds of Thar Desert. Analysis revealed that exclusi...
Using automatic sensor data, this is the first study to characterize individual cow feeding and rumination behavior simultaneously as affected by lameness. A group of mixed-parity, lactating Holstein cows were loose-housed with free access to 24 cubicles and 12 automatic feed stations. Cows were milked three times/day. Fresh feed was delivered once daily. During 24 days with effectively 22 days...
Gut fluorescence analysis of Calanus paczjkus and Metridia pacijica is used to describe variation in food intake rate at time scales of one to several hours. The animals are starved before each experiment, then exposed continuously to phytoplankton cultures. Variability of gut fullness is large (order IO-fold) between individual copepods captured at the same time and is about proportional to th...
