The freshwater angel fish (Pterophyllum scalare Schultze, 1823) is South American cichlid become very popular among aquarists. There is little information on their culture and aquarium husbandry. In this study growth performance and survival rate of angelfish subjected to different feeding frequencies were evaluated. Four groups of angel fish juveniles (0.87 ± 0.01 g; 3.98 ± 0.08 mm) were fed e...

background: prelacteal feeding is an underestimated problem in a developing country like india, where infant mortality rate is quite high. the present study tried to find out the factors determining prelacteal feeding in rural areas of north india. methods: a crosssectional study was conducted among recently delivered women of rural uttar pradesh, india. multistage random sampling was used for ...

Wetland habitats are used as nursery sites for hatchling and juvenile alligators (Alligator mississippiensis), where they utilize prey from aquatic and terrestrial settings. However, little is known about how viscosity of the medium influences feeding performance. We hypothesized that timing and linear excursion feeding kinematic variables would be different for individuals feeding on prey abov...

an experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, cyprinus carpio. four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % biogen probiotic were used to feed fish. seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 l capacity. during 60 days of feeding trial, the...

Analysis of the feeding kinematics of Astatotilapia (a small cichlid fish) suggests the presence of peripheral feedback modulation of the motor pattern, allowing the act of suction to be abbreviated. In this way, the effort spent in suction is minimized. The biological significance of the development of such a modulating feedback system is not immediately obvious from a ‘classical ecological’ p...

Since 1970, sow reproductive performance and prolificacy has improved dramatically. Today’s sow is genetically quite different. She is larger framed, with less back fat and more lean body tissue, besides having higher reproductive demands. The prolific, high-lean sow can raise more pigs per year, but also produce more milk resulting in heavier pigs at weaning. However, swine operations have a h...
