POPOVA, T., P. MARINOVA, V. BANSKALIEVA and V. VASILEVA, 2008. Content and fatty acid composition of different fat depots of lambs receiving fish oil supplemented diet. Bulg. J. Agric. Sci., 14: 100-107 Two groups of 7 animals (age 75 days) each of local Zapadnostaroplaninska sheep breed were fed for 28 days controlled iso-nitrogenous diets, containing either no added fat (control) or fish oil ...

The study was designed to investigate the effect of duration of frozen storage on the chemical, microbiological and sensory profile of Tilapia fish (Sarotherodun galiaenus) collected from a research pond of the Agricultural Development Project, Akure, Nigeria, subjected to sixty days of frozen storage and analyzed at intervals of ten days. Protein content (%) ranges from 43.70 +/- 1.17-60.65 +/...

Anchovy (Engraulis encrasicolus, L.) is the only European representative of the Engraulidae family and it is an endemic species of the Mediterranean-Atlantic region. It belongs to the group of small pelagic fish, caught along the Mediterranean shores and widely spread in the Adriatic Sea. The migration of anchovies from coastal regions towards open sea waters is related to their age and size, t...

A factorial design was used to study the effect of changes in broiler feed on the composition and consumer acceptability of chicken meat. One week before slaughter, 1.25% dietary fish oil was removed from the feed and replaced by other fat sources (animal fat or linseed oil) or we continued with fish oil, and diets were supplemented with Zn (0, 300, or 600 mg/kg), and Se (0 or 1.2 mg/kg as sodi...

A non-destructive method to predict the total lipid content and the lean body mass (LBM) was evaluated by measuring the total body electrical conductivity (TOBEC) with common carp. This technique is based on the principle that body fat and fat-free mass differ in electric properties which can be measured in a low-frequency electromagnetic field. Experimental fish with average body weight of 122...

The aim of this study was to investigate changes in the microbiological and physiochemical characteristics in Egyptian salted-fermented fish (Feseikh) during processing, ripening and storage. Isolation of total viable bacteria, Enterobacteriaceae, lipolytic bacteria, proteolytic bacteria, total spore forming bacteria (CFU/g) and Clostridium perfringens (MPN) from fish flesh, fish intestine and ...

The effect of the type of non-protein energy (NPE) on energy utilisation in Nile tilapia was studied, focusing on digestible energy utilisation for growth (k(gDE)). Furthermore, literature data on k(gDE) across fish species were analysed in order to evaluate the effect of dietary macronutrient composition. A total of twelve groups of fish were assigned in a 2 × 2 factorial design: two diets ('f...

In a previous study we showed that feeding fish meal significantly increased muscle long chain n-3 fatty acids (FA) and hot carcass weight. In this study we compared the effect of fish meal and fish oil on increasing muscle long-chain FA. We also investigated whether the increase in carcass weight was due to the effect of dietary enrichment of muscle long-chain n-3 FA on muscle membrane phospho...

Investigation into proximate and mineral content of three commercially important fish species (Lates niloticus, Clarias anguillaris and Hemisynodontis membranaceus using the traditional smoked method was conducted. Proximate analysis showed significant differences (P< 0.05) among the fish samples. However, there was no significant difference in their mineral content. Crude protein in fish sampl...

The aim of the study was to determine an influence of diet additives in a form of protected palm oil, protected fish oil or unprotected fish oil with glycerol in Polish Holstein-Friesian cows on milk fatty acid composition, metabolism, milk yield and milk composition. Milk production, milk fat, and milk protein did not differ statistically between the groups. A significant increase (P<0.01) in ...
