The umbilical and nasopharyngeal flora of newborn infants was examined on days 3, 14, and 42 of life. An analysis of the bacteriological findings suggests that colonisation by either Staphylococcus aureus or Staph. epidermidis prevents colonisation by the other staphylococcus. Similarly, colonisation by Gram-negative bacteria prevents colonisation by staphylococci. Further, this bacterial inte...

Background: Reported concentrations of amyloid(1– 42) (A 42) and tau in cerebrospinal fluid (CSF) differ among reports. We investigated the effects of storage temperature, repeated freeze/thaw cycles, and centrifugation on the concentrations of A 42 and tau in CSF. Methods: Stability of samples stored at 80 °C was determined by use of an accelerated stability testing protocol according to the A...

The present study was carried out to determine the effects of using dried rose dreg (DRD) as an alternative litter material for broiler performance and microbiological characteristics of litter. A total of 225 day-old broiler chicks was raised on pine wood shavings (PS), DRD and PS+DRD until 42 days. The effects of litter material on broiler performance and FCR did not differ. At 42 days the ef...

this research was conducted to evaluate the effects of adding five levels of ferula assa foetida powder (0, 0.25, 0.50, 0.75 and 1 percent of diet) on performance, humoral and cellular immune status and cecal microbial population. a total of 200 one-day-old mixed sex ross 308 broiler chicks were randomly assigned to 5 experimental groups with each four replicates and 10 birds in each replicate,...

The objective of the study was to evaluate productive, carcass, and tibia mineralization responses in broiler chickens supplemented with a liquid extract humic substances (HS) drinking water. Chicks were housed holding cages from 8-42 days age randomly assigned one five increasing HS levels water (0, 161, 322, 483, 644 µg/L). At 21 42 days, obtain carcass measurements half broilers slaughtered....

An experiment was carriedout to investigate the effect of dietary energy level levels on feed intake modern broiler chickens during growth period. A total 160 Ross chicks (mixed-sex) in a completely randomized design with 4 treatments and replicates (10 birds) were used. The fed from 11 24 days age treatments, including grower diets 2800, 2900, 3000, 3100 kcal/kg ME constant nutrient ratios. Al...

This study was designed to investigate the effects of different levels of Tarragon powder on performance and carcass’ characteristics of broiler chickens. 200 one-day-old Ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. Experimental diets were set on the basis of corn-soy-wheat and Ross 30...
