Effect Of DMPT On The Luring Performance And Intestinal Digestive Ferment Activity Of Allogynogentic Crucian Carp

This study investigated the effects of supplementary dietary of different concentration of DMPT (100mg/kg, 200mg/kg, 300mg/kg, 400mg/kg) and 0.3% Betaine on eating behavior; grow performance, meat quality of Allogynogentic crucian carp, and to probe into the best adding amount of DMPT. Compare its result of adding with 0.3% Betaine at the same time; in addition, study the impact on Allogynogentic crucian carp intestinal digestive ferment activity.This experiment is divided into the behavioral of Luring experiment, the raise experiment,the active determination of enzyme tests three parts. In the behavioral of Luring experiment,one aquarium have 20 fishes,Raise for 15 days in advance,is trying for 6 days. Raise and feed the basal ration of the raise experiment and three basal ration balls are hung in aquariumn in advance, test fishes pecking and gripping to basal ration balls in training before the formal experiment. After the formal experiment begins,carry on a group of experiments to determine at 8 o'clock every morning.In the raising experiment,choose 360 healthy allogynogentic crucian carp in a suitable place to breed the samly. This experiment Divided into six groups at random,each group have three repetition, every aquarium have 20 Allogynogentic crucian carps.Five experiment groups feed dietary add 100mg/kg,200mg/kg,300mg/kg,400mg/kg of DMPT and...
