An experiment was conducted to increase the quality of rice bran by fermentation using Bacillus amyloliquefaciens and humic substances and its utilization as a feed ingredient for broiler chickens. The experiment was carried out in two steps. First, the fermentation process was done using a completely randomized design in factorial with 16 treatments: i) Dosage of B. amyloliquefaciens (2.10(8) ...

The objective of this experiment was to evaluate the influence of glutamine (Gln) supplementation in the diet of broiler chickens on the growth performance, immune response as well as some blood parameters. Two hundred fifty one day old broiler chickens were allotted into five equal groups (50 chicks per each) of mixed sex. Five experimental diets were formulated to be isonitrogenous and isocal...

Hygiene management is essential for rearing Campylobacter free broiler flocks. In this study, several hygiene factors (e.g., thinning, water supply, stable cloths, stable condition, stable environment, etc.) are categorized and aggregated in a developed risk priority number (RPN). This number is measuring the quality of hygiene management of a broiler farm with one single value (range: 801–4005...

Increased mortality and problems with lameness were reported in Dutch broiler flocks from the year 2008 onwards. Therefore, a field inventory, including 10 affected broiler flocks, nine corresponding broiler breeder flocks and five hatcheries, was carried out. The onset of clinical signs (lameness and increased mortality) started at about 2 weeks of age. The flock mortality varied from 3.1 to 8...

The body weight of breeding broiler chickens (broiler breeders) is an important control variable used to optimize the amount, quality and fertility eggs being laid. In modern barns, population animals generally supports a female:male ratio 10:1, wherein males females each receive their own food supply. To this supply breeders are weighed using automatic electronic platform weighers weights then...

Introduction of biologically active supplements to the diet poultry results in maximal use nutrients and positively influences live weight slaughter parameters. This promotes rational economical fodders boosts productivity. We studied a mineral feed supplement – an organic selenium compound, which has much greater bioavailability than inorganic sources selenium. Selenomethionine is easily diges...

This experiment was conducted to investigate the effects of olive leaf (OL) on immune response and some blood metabolites of broiler chickens. A total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. Birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% OL powder from 14 to 4...
