this experiment was conducted to evaluate the effects of different levels of dried lemon pulp (dlp) on performance, carcass traits, blood biochemical and immunity parameters of broilers. in this experiment 240 of broilers (ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. experimental diets included: 1) ...
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 objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of NRC requirements) with or without of multi strains probiotic (Primalac) on performance, carcass characteristics and blood metabolites of Japanese quails. A total of 180 one-day-old male Japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...
ABSRACT The present experiment was designed to evaluate the effect of different protein and energy levels on broilers performance under hot climatic conditions. A total of three hundred Ross-308 chicks were selected on basis of uniform starting live bodyweight (45g/chick) proximately. Chicks were randomly divided into three treatments with five groups of 20 chicks per pen. Diets were formulated...
methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. to accomplish higher methanol conversion and lower co production, the reaction was catalyzed by cuznfe mixed oxides. various ratios of fe and cu/zn were coprecipitated in differential method to optimize the cuznfe structure. the sample containing 45cu50zn5fe (wt. %) revealed its m...
The current study aimed to evaluate effects of four levels (0, 2, 4 and 6 % of diet) of soybean lecithin in the isoproteic and isoenergitic (50% protein and 18.5 kj/g) diets on growth performance, feed utilization and hematological parameters of juvenile sobaity seabream (Sparidentex hasta) with initial weight of 37.9±0.16 g. At the end of 56 days of feeding trial, results showed that growth pe...
A trial was conducted to evaluate the performance of broiler birds which supplemented with a commercial inactivated probiotic. Four hundred and fifty day old broiler chickens were allocated into 3 treatments with 6 replicates each. Each replicate was placed on clean wood shavings in floor pens receiving feed and water ad libitum. In treatment 1, feed was supplemented with 500 g/ton of a heat-in...
Six hundred day old unsexed broiler chicks were used in a 42-d trial at Chittagong Veterinary and Animal Science University Poultry Farm to compare the effects of different levels of fish oil supplementation on performance of broilers in terms of feed intake, weight gain and feed conversion and carcass characteristics. The chicks were randomly distributed following a completely randomized desig...
the objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of nrc requirements) with or without of multi strains probiotic (primalac) on performance, carcass characteristics and blood metabolites of japanese quails. a total of 180 one-day-old male japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...
The Effect of Ginger Powder on Performance, Carcass Characteristics and Blood Parameters of Broilers
To study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (Ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). All treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called T1, 2T, T3 and T4 that were ad...
