New Technologies in Extrusion Process for Shrimp Feed por Muñoz, Osvaldo

“…This is why the feed must also generate lower levels of waste.It is well known that the extrusion process compared with the pelleting process, produce better nutritional quality feed, but in the particular case of shrimp, where a feed of high density and stable in the water is required, the extrusion by itself is not able to achieve these levels of desired density.The main characteristics of the shrimp feed are:- Water Stability, Digestibility, Quick sinking, Smaller size of the pellet, Reduces pollution in the water, - Lowering costs in the feed and OtherAlthough the extrusion process requires a highest investment and also the operational costs are higher than the pelleting process, if the extrusion process has the appropriate technology for densification, it would be much cheaper with a much greater profit than the pelleting process and most importantly, with a better quality feed as a result.In this work we show the latest technological advances in this direction to achieve a feed for shrimp in high quality and low cost through the extrusion process.…”

Validity of the Wingate anaerobic test for the evaluation of elite runners por Legaz Arrese, Alejandro, Munguía Izquierdo, Diego, Carranza García, Luis Enrique, Torres Dávila, Celeste Guadalupe

“…For male runners, PP and MP outputs decreased with increasing distance (p , 0.001). This trend was also true for female runners (p , 0.005). However, for both sexes, there were no significant differences in the PP values among 100-, 400-, and 800-m runners, and there were also no differences in the MP values for subjects that ran distances of 100 m compared with the values for subjects that ran distances of 400 and 800 m. …”

Effect of taurine precursor on growth and taurine content of rarine fish por Haga, Yutaka, Nakamura, Kohei, Ushigusa-Itoh, Tomoko, Gonzales-Plasus Gallo, Mojena Maria, Kabeya, Naoki, Satoh, Shuichi

“…Considering risk of having malformation in fish fed cysteamine, cysteic acid is a better choice as taurine precursor. We also examined effect of taurine supplementation to non-fishmeal diet on distal intestine of juvenile red sea bream. …”

Recent Developments in Shrimp Feeds & Feeding por Tacon, Albert G.J.

“…The above is perhaps not surprising since fishmeal and fish oil represent ideal feed ingredients for the aquaculture sector by possessing a nutritional profile approximating to the nutritional requirements of most farmed aquatic species, including shrimp; fishmeal not only being an excellent source of dietary protein and essential amino acids but also being a good source of nucleotides, essential fatty acids, phospholipids, minerals, and trace elements (including calcium, phosphorus, magnesium, zinc, manganese, selenium, iodine, molybdenum, and chromium), and fat soluble and water soluble vitamins (including vitamin A, D, E, choline, inositol, and B-vitamins).It follows from the above discussion therefore that efforts to replace fishmeal with alternative and more sustainable protein-rich feed ingredient sources should focus not only on making good any amino acid imbalances through dietary supplementation with aquaculture-grade free amino acids and dipeptides, but must also consider the dietary supplementation of the numerous other essential nutrients usually by fishmeal, including nucleotides, taurine, cholesterol, HUFA, minerals and trace elements. …”
