The aim of this study was to determine the effect of fish meal and mineral-vitamin premix, supplementing organic diets, on the performance of pigs and some meat and blood characteristics. The experiment was conducted on an organic pig fattening farm. The study involved 120 pigs with an approximate 25 kg body weight. Animals were divided into 3 groups, kept in pens, 10 animals each. Group I (con...

Traditionally, fish meal and fish oil have been used as main sources of proteins and energy in the commercial fish feeds. Nowadays these ingredients have been partially substituted with materials of plant-origin (e.g. maize, wheat and soy) due to their more inexpensive price and easier availability. If contaminated plant material is used in the making of fish feed, the finished product can cont...

Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six ...

The authors evaluated effects of feeding ranch mink (Mustela vison) diets containing polychlorinated biphenyl (PCB)-contaminated fish from the upper Hudson River (New York, USA) on adult and offspring organ mass and pathology. Diets contained 2.5 to 20% Hudson River fish, providing 0.72 to 6.1 µg ΣPCBs/g feed (4.8-38 pg toxic equivalents [TEQWHO 2005 ]/g feed). Absolute thyroid and adrenal glan...

The general consensus is that brain serotonin (5-HT) inhibits feed intake in teleost fishes and other vertebrates. Dietary manipulations with the 5-HT precursor tryptophan (TRP) have, however, yielded contradictory effects on feed intake, while studies of the endocrine response to stress indicate that the effects of TRP-enriched feed are context dependent. A characteristic behavioural response ...

The phosphorus and nitrogen discharge via effluent of intensive trout farming system was quantified through the use of environmental indicators. The nutrient loads, the mass balance, the estimated amount of nutrients in feed and the amount of nutrients converted in fish biomass were calculated based on the concentrations of phosphorus (P) and nitrogen (N) in the feed and in the water. Of the of...

In Turkey, it is known that, wastes of fisheries processing plants released to the environment and only a bit of that assessed as fish meal or fish feed by a few plant. It is expected that with the evaluation of these wastes which rich in nutrient content by converted to the various commercial products (chitin, protein hydrolyzate, carotenoprotein and pıgment extraction etc.) to be beneficial i...

Supplementary feed exogenous enzymes have improved the growth rates of various food animals. In thisresearch, the effect of Endofeed W, a multienzyme feed supplement, was investigated on the growth of carp.Accordingly, 134 fish (33.1 ± 0.8 g) were randomly allocated to 4 experimental groups. During the first stageof the experiment (10 days), groups 1-3 received 1, 2 and 3 g Endofeed W per kg di...

The aim of this research was to determine optimum dosage papain enzyme in feed for kissing gourami. This used Completely Randomized Design non-factorial, consist four treatments and three replications, namely: P0 (wihout supplementation feed/as a control), P1 (1.5% feed), P2 (3.0% P3 (4.5% feed). Kissing gourami with initial body weight 0.51+0.07 g were stocked each aquarium (volume 20 L water)...
