“…Soybean is the most important commercial source of lecithin and contains about 2% PL (Hertrampf 1991). Special processes are required to obtain crude lecithin, which contains about 71% PL and 28% soybean oil.…”

Two 6-week growth trials were conducted to determine the dietary phospholipids (PL) requirement of Litopenaeus vannamei juveniles and to compare the eect of dierent types of soybean lecithin on shrimp growth and survival. In the ®rst trial, a basal diet and diets containing 1.5, 3 or 5% (dryweight basis) of Type I lecithin (97.6% PL) and 1.5 or 3% of Type II lecithin (71.4% PL) were evaluated. In the second trial, the basal diet and diets containing 1, 2 or 4% of either Type I or Type II lecithin and 1 or 2% of Type III lecithin (48.4% PL) were evaluated. Results showed that there was no interaction between lecithin type and PL level on shrimp growth or survival. Shrimp growth increased with PL levels up to 3±5% of diet. No signi®cant dierences were observed for instantaneous growth rate (IGR) of shrimp fed the dierent types of lecithin at the same inclusion level, and no eect of PL level and lecithin type on shrimp survival was found. Thus, the recommended level of PL supplementation in diets for L. vannamei juveniles ranges from 3 to 5% of diet.

“…As an alternative plant protein ingredient, soybean meal is an economical and a commonly accessible protein source with comparatively high digestible protein, good amino acid profile, and high energy contents (Hertrampf and Piedad-Pascual 2000). Numerous studies have been performed to assess the nutritional requirement of different soybean products in Pacific white shrimp diets (Lim and Dominy 1990;Sudaryono et al 1995;Cruz-Suarez et al 2001;Smith et al 2001;Samocha et al 2004;Roy et al 2009).…”

Increasing worldwide competition and shifts in demand, technological advancements, and innovative findings out of research are triggering the ingredient manufacturing industry to include modified processing technologies and novel ingredients. New technologies have been introduced by the ethanol industry to improve the efficiency of ethanol production, resulting in new types of distillers dried grains with different nutrient profiles. One of the new processing techniques removes fibrous corn components before fermentation and removes the soluble fraction after fermentation to produce a high‐protein distillers grain with yeast (HP50Y with 49% protein and HP40Y with 40% protein). The current study was conducted to evaluate the efficacy of HP50Y and HP40Y as a replacement for corn protein concentrate (CPC) in diets of Pacific white shrimp Litopenaeus vannamei. In the first diet series, graded levels of HP50Y (0.0, 5.0, 10.0, 15.0, and 20.0%) were used to replace CPC (13.1, 10.0, 6.6, 3.5, and 0.2%). In the second diet series, graded levels of HP40Y (5.0, 10.0, 15.0, and 20.0%) were used to replace CPC (10.5, 8.0, 5.5, and 2.5%). These diets were evaluated over a 40‐d growth trial (initial weight = 0.54 ± 0.01 g; n = 4). At the conclusion, no significant differences were detected in growth, feed conversion ratio, survival, and food consumption of Pacific white shrimp (P‐value >0.05). However, results from regression analysis revealed that there was a significant increase in percent weight gain of Pacific white shrimp as the percent inclusion level of HP50Y and HP40Y increased in the shrimp diets. Results indicate that HP50Y and HP40Y are both good protein sources and can be used up to a 20% inclusion level in the diets of Pacific white shrimp.

Fatty Acids in Fish

Fatty Acids

View full text Add to dashboard Cite

The human body cannot synthesize certain fatty acids: these essential fatty acids must be consumed in the diet. Fish and other aquatic foods are known to be the main sources of polyunsaturated fatty acids (PUFA); therefore, humans obtain most of their eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) by consuming fish, aquatic invertebrates, and algae. The increasing demand for fish and the stabilization of marine fish and freshwater landings have contributed to a widening gap between demand and supply for fish and fish products. This leads to a necessity to improve aquaculture production. Fish are the main contributors of n-3 PUFA in the human diet, although there are some interspecific and intraspecific differences in fatty acid profiles. The fatty acid composition of fish differs depending on a variety of factors, including species, diet, as well as environmental factors such as salinity, temperature, season, geographical location, and whether the fish are farmed or wild. In this chapter, information will be provided on fish fatty acids based on their ecology, feeding habits, lipid contents, and environmental conditions where they are harvested.
