Replacement of fish meal by earthworm meal (Eiseniafoetida) in Siberian Sturgeon (Acipenserbearii) diet and its effect on growth performance, feed efficiency and carcass composition
A 12-week feeding trial was carried out to assess the effect of fish meal replacement by earthworm meal (Eiseniafoetida) on growth performance, feed efficiency and carcass composition of Siberian sturgeon (Acipenserbaerii). Fish with mean weight 21.32 ± 1.91 (mean ± SD) were fed with five experimental diets which 0% (Control), 10% (EWM10), 20% (EWM20), 30% (EWM30) and 40% (EWM40) of fish meal p...
متن کاملEffect of different level of spirulina meal on growth performance, feed efficiency, body composition and apparent digestibility of Oscar fish (Astronotus ocellatus)
The main objective of this study was to determine the effects of diets containing 0, 2.5, 7.5% spirulina platensis meal on growth performance, survival rate, skin pigmentation and digestibility of carotenoids in Oscar fish (Astronotus ocellatus). 288 Oscar fish with mean body weight of 10.73±0.09 randomly divided in to 24 aquariums with 45 liters’ water capacity. The experimental treatments wer...
متن کاملBiofilm forming abilities of Salmonella are correlated with persistence in fish meal- and feed factories
BACKGROUND Feed contaminated with Salmonella spp. constitutes a risk of Salmonella infections in animals, and subsequently in the consumers of animal products. Salmonella are occasionally isolated from the feed factory environment and some clones of Salmonella persist in the factory environment for several years. One hypothesis is that biofilm formation facilitates persistence by protecting bac...

fishing per somewhat longer voyage and more fish per day at sea and per ton of fuel. These two British pioneer experiments have indicated two possible ways of improving the exploitation of wide-ranging fisheries. 'Those who rely on supplies brought in by distant-water trawlers may before very long be freezing sizeable quantities at sea' (European Productivity Agency of the Organisation for Euro...
متن کاملFeed Efficiency Opportunities with 2008 Feed Cost
With the milk to feed ratio at 2.36 in February, 2008, dairy managers must carefully reviewing feed inputs relative to milk yield. A milk to feed ratio under 3 is a signal to reduce feed inputs. Feed efficiency (also referred to as milk performance efficiency and dairy efficiency) can be defined as pounds of 3.5%FCM (fat corrected milk) produced per pound of dry matter (DM) consumed. Monitoring...
