ABSTRACT
Effects of s u p p l e m e n t e d different plant a n d concentration feeds on growth performance of Gryllus biniaciilattis crickets
This study was done to evaluate the effects of different dietaiy suppiemention of plant and concentration feeds on growth performance of Gryllus biniaculatus, an experiment was completely block randomized design into 3 dietary treatments and replicated four times The experimental diets were as followed as: control was a diet contained 2 1 % CP plus cassava leaves (DC), NTI and NT2 consisted of a diet contained 32% CP plus lettuce or water spinach leaves, respectively.
The experiment was carried out for 5 weeks. Results showed that the average temperature and humidity recorded in the trays were 27-35'C and more than 65%. Total number of eggs laid and egg weight were not sigmficant differences a m o n g treatments There was a different signihcance among treatments on hatchability at 8, 9,10 and 11"" day, highest was on NT2 and lowest on control.
NT2 was given highest survival rate at day 7"' post hatchabilitj', however it was lowest survival ratL- at day 5"' and day 9"' post hatchability and lowest on control. Besides, NT2 had highest body weight compared lo control at 14, 21, 28 and 35 days-old. Similarity', NT2 was given highest daily weight gain at 14-21 and 22-28 days old as well as accumulative weight gain at 14-35 days old. Ether extract and crude prolein components of cncket on N T I (31.5% EE and 72.9% CP) were higher than control (15-8".. EE and 60.9% CP) and NT2 (14.2% EE va 66.2% CP). It is concluded that NT2 and NTI supplemented 32%CP plus lettuce or water spinach leaves stimulated egg hatch early and weigh belter NTI improved nutritional value of EE and CP content of crickets
Keywords: Supplemented feed, hatchability. body xvetgltf, weight gain, cricket.
