Investigation of the influence of different level of plant protein (30, 50 and 70 percent) in Litopenaeus vannamei shrimp diet, with 38 percent protein
The influence of different percents of plant protein (30, 50 and 70) in the diet of white leg shrimp (Litopenaeus vannamei) with 38 percent protein, in comparison with a commercial shrimp diet (Fenneropenaeus indicus) with 39 percent protein (contain20 percent plant protein) was studied. Initial weight of shrimp was 10±1 gram. The average increase of shrimp weight in the end of culture period in experimental treatment 1 (contain 30 percent plant protein and 70 percent animal protein), 5.89±0.06 gram, experimental treatment 2 (contain 50 percent plant protein and 50 percent animal protein), 6.22±0.25 gram, experimental treatment 3 (contain 70 percent plant protein and 30 percent animal protein) 6/19±0/24 gram and in the control treatment (contain 20 percent plant protein and 80 percent animal protein) 6/42±0/40 were measured. Generally in the study of influence of experimental diets and control diet on the growth rate(GR), food conversion rate (FCR), protein efficiency ratio (PER), specific growth rate (SGR), average daily gain (ADG), demonstrate that, mentioned parameters in the control treatment is better than experimental treatments. But no significant difference measured between them (p>0/05). Also results showed that, application of diets contain 50 percent of plant protein (with 22 percent soybean meal), and 70 percent of plant protein (with 72 percent soybean meal), can decrease costs of diet preparation and therefore shrimp production.

| Summary: | The influence of different percents of plant protein (30, 50 and 70) in the diet of white leg shrimp (Litopenaeus vannamei) with 38 percent protein, in comparison with a commercial shrimp diet (Fenneropenaeus indicus) with 39 percent protein (contain20 percent plant protein) was studied. Initial weight of shrimp was 10±1 gram. The average increase of
shrimp weight in the end of culture period in experimental treatment 1 (contain 30 percent plant protein and 70 percent animal protein), 5.89±0.06 gram, experimental treatment 2 (contain 50 percent plant protein and 50 percent animal protein), 6.22±0.25 gram, experimental treatment 3 (contain 70 percent plant protein and 30 percent animal protein) 6/19±0/24 gram and in the control treatment (contain 20 percent plant protein and 80 percent animal protein) 6/42±0/40 were measured. Generally in the study of influence of experimental diets and control diet on the growth rate(GR), food conversion rate (FCR), protein efficiency ratio (PER), specific growth rate (SGR), average daily gain (ADG), demonstrate that, mentioned parameters in the control treatment is better than experimental treatments.
