The digestive fluid of Dionaea muscipula has been studied with respect to its protein content as a function of time after entrapment of protein material and some enzymes of the secretion. Maximum secretion of enzyme occurs within the first 3 days of the digestive cycle and protein reaches its maximum at 4 days. Phosphatase, proteinase, nuclease and amylase have been observed in the secretion. T...
This experiment was designed to investigate the use of live Eisenia fetida as a nutritional supplement on growth performance and carcass composition The purpose of this study was to evaluate the nutritional efficiency and changes in digestive enzymes of rainbow trout (Oncorhynchus mykiss). Fish were placed with average weight 58 g in a completely randomized design in 4 treatments and each with ...
Final instar larvae of S. mauritia treated topically on day 0, 1, 2 and day 3 with a daily dose of 20 microg juvenile hormone analogue (JHA) showed an increase in most of the nutritional parameters such as approximate digestibility, efficiency of conversion of ingested food, consumption index and growth rate. Also, the activities of digestive enzymes amylase, invertase, trehalase and protease i...
The aim of the present study was to investigate the effect of Lactococcus lactis and Weissella cibaria probiotics on growth performance, intestinal bacterial flora, digestive enzymes and intestinal histology in common carp (Cyprinus carpio). Fish with an average initial weight of 17 g were divided into 10 treatments with 3 replications. Fish food in treatments 1, 2 and 3 were supplemented with ...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
An experiment was conducted to evaluate the effects of wheat and wheat bran diets with and without enzymes on growth performance and digestive characteristics of broilers. A total number of 625 one day old Ross-308 broiler chickens were allocated randomly to 5 treatments with 5 replicates, using a CRD statistical design. Treatments were control, wheat, wheat+ enzyme and wheat bran and wheat bra...
