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...

: 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...

An 8-wk experiment was conducted to evaluate the effect of replacing fish meal (FM) with soy protein isolate (SPI) on the growth, digestive enzyme activity and serum biochemical parameters of juvenile Amur sturgeon (Acipenser schrenckii). SPI was used to replace 0, 25, 50, 62.5, 75, 87.5, 100% of dietary FM and 100% replacement supplemented crystalline amino acid. Healthy sturgeon with an avera...

Two experiments were conducted to evaluate the effects of irradiated ingredients in meal and pelleted diets on nursery pig performance. In Exp. 1, a total of 192 pigs (initial BW, 6.0 kg) were used in a 25-d experiment. Pigs were blocked by BW and randomly allotted in a 2 x 2 factorial arrangement of treatments with main effects of diet form (meal or pellet) and either irradiated (11.92 kGy) or...

Two 3 x 2 factorial growth trials and a companion metabolism trial with 13, 15, or 17% dietary CP (DM basis), with or without 3% of the DM replaced with slowly degraded menhaden fish meal, were conducted to determine if level of dietary protein influences whether slowly degraded protein improves lamb growth and protein use. The growth trials included 32 and 34 pens of two weanling lambs initial...

I . A total of six diets based on maize silage were formulated to examine the effect of proteinand non-protein-nitrogen, and energy supplementation on the flow of amino acids to the small intestine and the synthesis of microbial amino acids in the rumen of growing cattle. All diets contained 24 g total nitrogen (N)/kg dry matter (DM), of which 550 g N/kg total N was supplied by either urea or f...

Fish meal is currently the major protein source for commercial aquaculture feed. Due to its unstable supply and increasing price, fish meal is becoming more expensive and its availability is expected to face significant challenges in the near future. Therefore, feasible alternatives to fish meal are urgently required. Microalgae have been recognized as the most promising candidates to replace f...
