The present study evaluated the effect of Lactobacillus plantarum as a probiotic on the growth performance and haematological parameters of juvenile rainbow trout (O. mykiss) weighing 29.6±1.8 g immunized with streptococcus/lactococcus vaccine. Fish were randomly allocated into 4 equal groups consisting of fish fed with the probiotic supplemented in diet (group P), fish immunized with streptoc...
Two experiments were conducted to evaluate the nutritional value of millet and tallow for broiler chickens. In the first experiment, the nitrogen corrected apparent metabolizable energy (AMEn) of millet and tallow were determined by the method of Sibbald. In the second experiment, a 3×5 factorial experiment was designed to evaluate the effects of 3 levels of tallow and 5 levels of substitution ...
An experiment was carried out to evaluate the effect of addition various levels of apple vinegar (zero, 1 and 2%) in drinking water on growth performance, gastrointestinal tract organs chyme pH, ileal lactobacillus population and immune responses of broiler chickens. One hundred and sixty day old male Ross 308 broiler chicks were allotted in a completely randomized design with three treatments,...

We studied the influence of enzyme supplementation (ES) of the diet and heat processing (HP) of barley on digestive traits and productive performance of broilers from 1 to 42 d of age. There were 6 diets arranged factorially with 2 doses (0 and 500 ppm) of a fungal enzyme complex with beta-glucanase and xylanase activity and 3 HP of barley (raw, micronized, and expanded). In addition, a control...
this experiment was conducted to evaluate the effects of different levels of crude protein and probiotic in diets on performance, egg quality and blood biochemical and immunity parameters of laying hens. a completely randomized design with factorial method (2×4) was conducted in which two levels of crude protein (nrc and 10% lower than nrc recommendation) and 4 levels of probiotic (0, .025%, 0...
This study was conducted to investigate the effect of different levels of sesame meal (SM) on performance and carcass characteristics of Japanese quail. One hundred sixty day-old Japanese quail chick were equally distributed into 16 cage pens and reared form 10 to 42 days of age. The treatments consisted of SM0, SM50, SM100 and SM150. The diet for SM0 treatment had no SM (control), while those ...
digestibility in broiler chickens fed on corn-soybean meal based diets. the experimental diets consisted of 1.corn-soybean meal based control diet 2. control diet supplemented with pectinas, 3. control diet supplemented with cellulase, 4. control diet supplemented with pectinase + cellulose, 5. control diet supplemented with pectinase + hemicellulase and 6. control diet supplemented with pectin...
The experiment was conducted to evaluate the effect of antibiotic, organic acid, probiotic and prebiotic on performance and small intestinal morphology in male Ross 308 broiler chicks for 42 days in tropical conditions. The study was completely randomized design with 5 treatments, 4 replicates and 8 chicks per each. The treatments were: T1: basal diet, T2: diet containing antibiotic oxytetracyc...
We evaluated the effects of dietary Carum copticum essential oil (CCEO) on growth performance, carcass characteristics and intestinal microflora of broiler chickens. A total of 240 Cobb broiler chickens were allocated to five dietary treatments, each with four replicates of 12 birds. Dietary treatments were prepared by formulating a corn-soybean meal-based diet free of antibiotics (Control) and...
