A digestibility trial was conducted to examine the effect of feeding rate on dry matter, gross energy, crude protein and phosphorus digestibility in Atlantic salmon (Salmo salar). Duplicate groups of fish were fed 0.25, 0.5, 0.75, 1.0, 1.25 and 1.9% BW/day. The faeces were collected by Guelph-type collectors for five successive days. Dry matter, protein and phosphorus digestibility’s wer...

The present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of Indian white shrimp post-larvae. Four hundred and fifty Indian white shrimp post-larvae (PL1) were stocked in nine tanks. The tanks were assigned into three treatments: feeding with inulin-treated (110 mg L-1) Artemia nauplii ...

Investigations were carried out on coal tailings by conventional cell and column flotation techniques. Tests were conducted to assess processing coal tailings of Alborz Markazi coal washing plant in Iran by column flotation. The effects of reagent type/dosage were investigated with conventional flotation and their results were used in the performance of column flotation. Also the effects of the...

Insulin responsiveness to glucose and tissue responsiveness to insulin, using the hyperglycemic clamp and the hyperinsulinemic euglycemic clamp techniques, were measured before, during and after feeding in sheep fed an alfalfa hay and commercial concentrate diet. Glucose infusion rate and the plasma insulin increment in the hyperglycemic clamp experiment were higher during the feeding period (0...

the objective of this study was to investigate the effects of different levels of amino acid and feeding methods on performance and immune system of broiler chickens. experimental design was based on completely randomized design in a factorial arrangement with 3 feeding methods [control (ad libitum feed intake), intermittent feeding (if) and continuous feed withdrawal (fw)), and 2 amino acid le...

Rainbow trout is the most important species of cold water fishes in Iran and the feeding diets which improve the quality and growth of this fish are of great importance. Rainbow trout Oncorhynchus mykiss (n=360) specimens with approximate weight of 2±0.02g were fed with different concentrations of sesame seed in their diet instead of fish meal for 120 days. Feeding diets were prepared in 3 sesa...

The feeding behavior of 19 mule ducks (males and females) bred in a group was studied during their growth phase (between 3 and 8 wk of age) using the recording system for waterfowl feeding behavior developed in our lab. The basic feeding behavior data obtained allowed us to confirm on the one hand the reliability of our tool and, on the other hand, to compute food intake traits per day (ADFI, n...
