Add the various dose additive to grazing rate to influence test-results as follows: various additives and additive capacity have all improved the grazing rate of experimental animal to a certain extent, new food calling thing chloro dimethylthetin food calling effect proposed by the invention is obvious, its suitable addition is 400ppm, and two kinds of phagostimulants all improve grazing rate 30~45% in its suitable addition situation.
Application Example 11:
Chloro dimethylthetin promotes growth and anti-stress effect.
Experimental animal and management: select for use hybridized prussian carp as the culture experiment fish, for culturing fingerling then in the pond, mean body weight 30.7 ± 1.6g, after two weeks supported temporarily, random packet, every group 13 tail.Outdoor recirculation system carries out, single cylinder is rectangle 1m * 0.5m * 0.6m aquarium, with the tap water through quick-fried gas is the water source, replenish Total Water 5~10% every day, aquaculture water is through precipitation, flow in the water reservoir after filtering out residual feed and ight soil, be extracted into each culturing jar by the water pump gap again through after the oxygenation.The experimental session water temperature is 15~26 ℃, and dissolved oxygen remains on more than the 6.0mg/L, and the pH value is 6.5~7.5.Si material is thrown something and fed every day 3 times, and feeding volume is 3~4% of a body weight.Formal culture experiment begins back accumulative total and carried out 92 days, is divided into three phases sampling weigh (0-27 days, 28-55 days, 56-92 days).
Speed of growth index: moment, growth rate=(lnW2-lnW1)/(T2-T1), W2 and W1 were respectively the body weight when beginning and finishing, and T2-T1 is a culturing time.
Crucian body index: the fish body is estimated with body weight/body length, internal organ weight/body weight, liver pancreas/body weight, spleen weight/body weight.
Immunizing power is measured: measure serum lysozyme (LSZ), superoxide-dismutase (SOD), gpt (GPT), blood oxyphorase.
The anti-transportcapacity of crucian is measured: after culture experiment finishes, every test group is got 5 tail fishes, the pack oxygenation is tested with rotating speed 120rpm simulate on shaking table, replenished every 4 hours and once to fill oxygen, 14 hours time length, be calculated to be motility rate after the end, and measure blood content of hemoglobin, SOD in serum enzyme, N,O-Diacetylmuramidase and transaminase vigor immediately, to detect the anti-transportcapacity of crucian.
