Use of Corn Protein Products in Practical Diets for the Pacific White Shrimp
Corn protein products are commonly used to balance the amino acid profile of practical diets especially those with low levels of methionine. Yet, there is little information regarding the efficacy of their use. Consequently, the objective of this study was to evaluate the production response of Lito...

| description | Corn protein products are commonly used to balance the amino acid profile of practical diets especially those with low levels of methionine. Yet, there is little information regarding the efficacy of their use. Consequently, the objective of this study was to evaluate the production response of Litopenaeus vannamei fed diets with increasing percentages of corn protein products. Three standard indoor tank trials and a pond production trial were conducted. In trial 1, three diets were formulated to contain corn gluten meal (CGM) (8%) and increasing levels (6.5 and 13.0%) of corn protein concentrate (CPC). Five diets were evaluated in Trial 2, with diets 1 to 4 using increasing levels (0, 4, 8 and 16%) of CPC replacing soybean meal, while diet 5 contained a CPC with a better AA profile specifically higher levels of lysine, designated CPCL. The production diets contained increasing percentages (0, 4, 8, and 12%) of CPC as a replacement for fish meal. The diets were commercially produced and evaluated in 0.1 ha production ponds using four replicates per diet. Nursed juvenile shrimps (0.023 g initial weight) were stocked at 38 shrimp m-2 and were cultured under standardized pond production conditions for 16 weeks. At the conclusions; net yield (5007-5440 kg/ha), final mean weight (17.2-20.5 g), survival (64.9-83.6 %), and FCR (1.27-1.38) were evaluated with no significant differences between dietary treatments. The results from this study demonstrated that corn protein concentrate inclusion up to 12% CPC in diet can be used in commercial feed formulations for L. vannamei without causing negative effect on growth, feed conversion, survival and net yield. |
