Introduction: Cassiduloids play a prominent role in echinoid evolutionary history because they probably are the ancestral group of clypeasteroids. Some extant species brooding and rare environment. Consequently, there no studies on their maintenance laboratory. Objective: Establish an efficient aquarium system for C. mitis, endemic to Brazil, ontogenetic studies. Methods: Four systems were buil...

This study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. Two hundred and seven days old Arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (SSB); 3) basal diet + 1% non-processed sodi...

recombinant human erythropoietin (rh-epo) is known to accelerate erythropoiesis in preterm infants. the purpose of this study was to compare the effectiveness of early treatment with two doses of rh-epo (high vs. low dose) in the management of anemia of prematurity. twenty preterm infants with hematocrit (hct) < 30% when infant’s age was between 2 to 3 weeks after birth or hct <25% when infant’...

A total of 300 one-day old male broilers (Cobb 500) were randomly divided into four treatment groups. The groups comprised of 15 birds each, and were defined by diet and the birds in each group were fed 0 (control), 3, 5, or 7 kGy electron-beam irradiated diets. A total of 5 replicates were performed. The chemical composition of the diet was not affected by irradiation.Irradiation doses of 5 an...

The aim of the present study was to compare the efficacy of commercial herbal products on performance and immune response of broiler. One hundred twenty chicks were randomly divided into 12 experimental units (replicates) having ten chicks each. These experimental units were allotted to four treatment groups (T1, T2, T3 and T4) such that each treatment has three replicates. Group T1 was without...

this investigation was designed to determine the effect of intact ovalbumin and mannose-conjugatedovalbumin on the prevention of salmonella typhimurium adherence to the epithelium of small intestine ofchickens. mannose-conjugated ovalbumin was produced by maillard-type reaction between chickenovalbumin and d-mannose at 60°c. the results revealed that incubation up to 96 hrs caused the highestam...

the objective of this research was to investigate the efficacy of dietary inclusion of probiotics primalac® and bactocell® and prebiotic fermacto® on broiler’s performance and immune response, individually or in combination. a total of 540 one-d-old male ross 308 broiler chicks were allocated into 6 experimental treatments with 6 replicates of 15 birds per replicate from 1 to 42 d of age. the b...

The objective of this study was to evaluate whether the addition enzymes phytase and xylanase, isolated or associated, in liquid form after feed pelletization could improve energy utilization digestibility calcium phosphorus by broiler chickens. Three experiments were performed using 120 birds each, divided into five treatments with eight replicates per group (n = 3), identified as: experiment ...
