Effects of Dietary Corn Gluten Meal or Poultry Meal Partially Replacing Fish Meal on Growth Performance of Golden Pompano ( Trachinotus ovatus)
摘要
Abstract
Feeding trials were conducted to evaluate the effects of dietary corn gluten meal or poultry meal par?tially replacing fish meal on growth performance of golden pompano ( Trachinotus ovatus) , and to evaluate the suitable supplemental levels of corn gluten meal as well as poultry meal. Corn gluten meal replacing fish meal trial: six isonitrogenous and isolipidic experimental diets were formulated to contain 0 ( control ) , 6.4%, 11.8%, 17.3%, 22.7% and 28.1% corn gluten meal replacing 0, 5%, 10%, 15%, 20% and 25% fish meal, respectively. Each experimental diet was randomly fed to 4 net cages of 80 fish in each net cage for 12 weeks, with fish initial body weight of ( 101.70 ± 0.22) g. Poultry meal replacing fish meal trial: six isonitrogenous and isolipidic experimental diets were formulated to contain 0 ( control) , 5.2%, 10.4%, 15.6%, 20.8% and 26.0% poultry meal replacing 0, 5%, 10%, 15%, 20% and 25% fish meal, respectively. Each diet was ran?domly fed to 4 net cages of 80 fish in each net cage for 12 weeks, with fish initial body weight of ( 101.03 ± 0.59) g. The results showed that with the proportion of dietary corn gluten meal replacing fish meal increas?ing, the weight gain rate, specific growth rate, protein efficiency rate, protein retention rate, lipid retention rate and energy retention rate firstly increased and then decreased, while the feed coefficient and feed intake firstly decreased and then increased. Compared with control group, the weight gain rate, specific growth rate and protein efficiency rate of fish fed with 11.8% to 17.3% corn gluten meal diets significantly decreased ( P<0.05) , whereas the weight gain rate, specific growth rate, protein efficiency rate, protein retention rate, lipid retention rate and energy retention rate of fish fed with 28.1% corn gluten meal diet significantly decreased ( P<0.05) , meanwhile the feed coefficient and feed intake were significantly increased ( P<0.05). Compared with control group, the growth performance including weight gain rate, specific growth rate, feed coefficient, pro?tein efficiency rate and so on had no significant difference when fish fed with 5.2% to 20.8% poultry meal diets ( P>0.05) , while the weight gain rate, specific growth rate, protein efficiency rate protein retention rate, lipid retention rate and energy retention rate of fish fed with 26.0% poultry meal diet significantly decreased ( P<0.05). Feed coefficient of fish fed with 26% poultry meal diet was significantly higher than that of fish from control group ( P<0.05) , while fish from 5.2% to 20.8% poultry meal groups showed no significant difference ( P>0.05). Therefore, poultry meal and poultry meal can be added in diets to replace partial fish meal for golden pompano without negatively effects on growth. The suitable supplemental levels of corn gluten meal and poultry meal in diets of golden pompano are calculated by function models base on specific growth rate and feed coefficient, and they are 10.91% to 10.96% and 20.80% to 21.25%, respectively.[ Chinese Journal of Ani?mal Nutrition, 2019, 31(6) :2752?2764]关键词
