Apparent Digestibility of Nutrients in Thirteen Animal Feed Ingredients for White Shrimp Litopenaeus vannamei
摘要
Abstract
Apparent digestibility of nutrients in thirteen animal feed ingredients was determined for white shrimp Litopenaeus vannamei in this experiment. The thirteen animal feed ingredients included white fish meal (Russia) , low-temperature steam dried brown fish meal (Peru) , domestic flame dried fish meal, imported flame dried fish meal (Peru) , miscellaneous fish meal, spray-dried blood cells, drying blood meal, chicken meal, meat and bone meal, meat meal, fermented feather meal, hydrolyzed feather meal, and shrimp meal. Trial diets used with yttrium oxide (Y2O3) as an indicator, and consisted of 70% basal diet and 30% test in-gredients. One thousand two hundred and sixty shrimp with an initial average body weight of (13. 0±0. 1) g were randomly divided into 14 groups with 3 replicates per group and 30 shrimp per replicate. After one week feeding with trial diets, the fecal samples were collected by siphon, then the apparent digestibility of dry mat-ter, crude protein, crude lipid, gross energy, total phosphorous and amino acids was determined. The results showed as follows: apparent digestibility of dry matter, crude protein, crude lipid, gross energy, total phos-phorous and amino acids in thirteen animal feed ingredients were 58.11% to 76. 91% , 64. 17% to 93. 57% , 52. 44% to 95. 62% , 43. 00% to 95. 21% , 39. 11% to 76. 47% , and 63. 48% to 94. 06% , respectively. The apparent digestibility of amino acids had a positive correlation with apparent digestibility of crude protein for feed ingredients. The apparent digestibility of crude protein in white fish meal, low-temperature steam dried brown fish meal and imported flame dried fish meal was significant higher than that in other feed ingredients (P <0. 05) ; the apparent digestibility of crude lipid in fermented feather meal, hydrolyzed feather meal and drying blood meal was significantly lower than that in other feed ingredients (P <0. 05) ; the apparent digesti-bility of gross energy in white fish meal and imported flame dried fish meal was significantly higher than that in other feed ingredients (P<0.05) ; the apparent digestibility of total phosphorus in white fish meal, low-tem-perature steam dried brown fish meal, domestic flame dried fish meal and imported flame dried fish meal was significantly higher than that in spray-dried blood cells and drying blood meal (P <0. 05). In the thirteen feed ingredients, the highest apparent digestibility of dry matter, gross energy and total phosphorus was found in white fish meal; the lowest apparent digestibility of dry matter, crude protein and gross energy was found in hydrolyzed feather meal; the lowest apparent digestibility of crude lipid was found in drying blood meal. In conclusion, different sources and qualities of fish meal lead to different apparent digestibility of nutrients. The chicken meal, meat and bone meal, meat meal and shrimp meal were high quality protein sources for L. van-namei, and they can be used to instead of part of fish meal in actual feed production. While, because of the different produce processes of feather meal and blood meal, the nutrient composition is different among the products, and that lead to the different apparent digestibility. So, the nutrient composition of these feed ingre-dients should be evaluated before formulating diets.关键词
