asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

In this study the effects of different levels of raw and autoclaved rice bran (0, 6, 12 or 18%) on the growth performance, carcass parameters, internal organs and the nutrients digestibility were assessed. This experiment was designed on 420 fourteen-day-old male broilers (Ross 308). Birds were randomly divided into 7 treatment groups and 3 replications, each with 20 birds. Treatments were: 1= ...

The experiment was carried out using 200 Ross 308 broiler chickens in a completely randomized design with 5 treatment and 4 replicates. The experimental diets were consisted of a control free hulls diet and four diets containing 0.75 or 1.5 percent rice hulls with particle sizes of less than 1 mm or between 1-2 mm.  The performance traits were determined through 42 d experimental period and car...

   This study was conducted to evaluate the effects of raw and autoclaved Amaranth grain on the performance and egg quality of layer hens. For this purpose 168 Leghorn laying hens strain Hy-line W36 at 67 weeks of age were allocated in completely randomized design with 7 treatments and 6 replicates of 4 birds. Treatments include raw and autoclaved Amaranth each at 0, 5, 10 and 15%. The egg exte...

An experiment with 720 pullets was conducted to investigate the effect of dietary energy levels of pullet and dietary energy and fat of laying ration on subsequent performance parameters during 14-20 and 22-44 weeks of age. In the first period, white leghorn pullets were fed with two diets of low and high density energy (2600 and 3200 Kcal ME/kg). In the lating period (second period), birds, in...

The present study investigated the use of fermented Prosopis juliflora pods (PJP) as a carbohydrate source alternative to rice bran (RB), and a P. juliflora pods based diet formulation supplemented with probiotics Lactobacillus acidophilus (LA), Lactobacillus bulgaricus 009 (LB) and Streptococcus thermophilus (ST) on the growth of Labeorohita (rohu) fingerlings. The diets were isonitrogenous (3...
