Cystic echinococcosis (CE) is an important anthropozoonotic parasitic common in Algeria. The predominant life cycle of E. granulosus is a synanthropic cycle with domestic dogs as definitive hosts and livestock animals as intermediate hosts. Slaughter activity represents a potential source for dogs to access infected offal. The aim of the present study was to determine if the contact between dog...

Salmonids are fatty fish and contain high amounts of omega-3 polyunsaturated fatty acids, beneficial in human nutrition. However, the aquaculture industry has expanded greatly in recent decades, increasing demand for fishmeal (FM) and fish oil (FO) for fish feed, while the supply of fish raw materials has remained static or declined. This has created a need for alternative sustainable raw mater...

Effectiveness of low level monensin supplementation on N utilization in lactating dairy cows fed alfalfa silage was assessed using 48 multiparous Holsteins. Cows were fed a covariate diet [% of dry matter (DM): 56% alfalfa silage, 39% ground high moisture corn, 3% soybean meal, 1% ground corn, 1% vitamin-mineral supplements] for 2 wk, then grouped by days in milk into blocks of 4. Cows were ran...

Before and after the 3-year generic advertising campaign for fresh fish in Denmark, representative consumer samples were surveyed with regard to their attitudes towards fresh fish, perceived family norms, availability of fresh fish in shops, meal preparation skills, intentions to buy fresh fish, and actual consumption frequencies. In the pre-campaign survey (effective N = 641), significant dete...

The evaluations of insects’ protein as viable alternative source in fish diets are gaining more attention revealing that the has comparative advantage than other sources. Therefore, this study was conducted to isolate and identify (using phylotypic genotypic methods) bacteria isolates gastrointestinal tract (GIT) African hybrid catfish fed supplemented grasshopper meal. Four feeding were adopte...

Many studies with fin fish have demonstrated the potential to use alternative dietary protein sources to fish meal based on growth responses, although these trials mostly neglect to determine if such protein sources affect immune function. This study investigated the effect of fish meal replacement with dehulled lupin meal (LPN) or hydrolysed poultry feather meal (FTH). Atlantic salmon (Salmo s...

Several feed ingredients have been investigated in an attempt to substitute fishmeal in the diets of fish and livestock. These include both animal protein and plant protein sources. Unfortunately attempts to use these ingredients for complete replacement of the fishmeal component in tilapia diets have not entirely been successful. A major reason is the suboptimal content of essential amino acid...

: ed u/c ata log Bypass protein is an important part of the diet of lactating cattle. The National Research Council recommends that bypass protein make up 34 to 36 percent of the total crude protein consumed by lactating cattle. Fish meal is high in crude protein (65 to 70 percent) and is a source of bypass protein (also called ruminally undegradable protein or RUP). It can be used in dairy rat...
