Effects of Spirulina platensis on Growth Performance, Carcass Characteristics, Egg Traits and Immunity Response of Japanese Quails
In present study, two trials had been conducted to evaluate the effects of Spirulina platensis (SP) on growth performance, carcass characteristics, egg quantity and quality traits, and immunity response of Japanese quails. In trial 1, a total number of 180 one-day-old Japanese quails were randomly assigned into 6 groups, 3 replicates with 10 quail chicks per replicate. Experimental diets including basal diet (with no additive), diet contained probiotic, and diets contained 4 levels of SP (2.5, 5, 10, 20 g/kg diet). In trial 2, a total number of 250 Japanese laying quails were randomly assigned into 5 groups, 5 replicates with 10 laying quails per replicate. Experimental diets included of basal diet (no additive) and diets supplemented with three levels of SP (1, 3 or 5 g/kg diet). In experiment 1, using 5 g SP/kg diet caused higher body weight gain and European production efficiency factor during 1-35 d of age (P<0.05). Using SP at the levels of 2.5 or 5 g/kg diet increased breast percentage (P<0.05). In experiment 2, using different levels of SP decreased shell thickness, albumen height, haugh unit and yolk height in laying quails (P<0.05). However, Feeding different levels of SP increased (P< 0.05) egg yolk color compared to control group linearly. Dietary supplementation of SP at levels of 3 and 5 g/kg diet decreased cholesterol level per g yolk (P<0.05). Different levels of SP caused higher levels of total antibody against sheep red blood cells (SRBC) and IgG titers (P<0.05). Laying quails fed with 3 or 5 g SP/kg showed higher cutaneous basophil hypersensitivity after 12 or 24 h of phytohemagglutinin injection (P<0.05). In conclusion, we recommend using SP at the levels of 5 and 3 g/kg diet during growth and laying period of Japanese quails, respectively.
Effects of Salbutamol on growth performance and carcass characteristics of Japanese quail (Coturnix japonica)
The effects of feeding diets containing Salbutamol (0, 1, 3, 5 and 7 mg/kg diet) from 21 to 49 days of ageon growth performance and carcass characteristics in 180 male and 180 female Japanese quails (Coturnixjaponica) were studied using a factorial arrangement based on completely randomized design. Gender hadsignificant effect on weight gain (Pwere not statistically significant (P>0.05). Salbut...متن کامل

Value added by Spirulina platensis in two different diets on growth performance, gut microbiota, and meat quality of Japanese quails
AIM The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP) was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power. MATERIALS AND METHODS This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD])-...متن کامل
Three experiments were conducted to evaluate the in ̄uence of an algae derived feed additive, Spirulina platensis (SP), on weanling pig performance. In all experiments, pigs were blocked by weight and allotted to one of four (experiments 1 and 3) or six (Experiment 2) dietary treatments. Standard diets and feeding regimens were implemented in all three experiments and SP replaced soybean meal on...متن کامل
