Two repeated experiments were conducted to investigate the effects of different stocking densities onbroiler performance, carcass characteristics, litter quality and foot lesionsusing 5224 one day-old Ross 308 broilers. In each experiment, a total of 2612 one day-old broilers were allocated in 16 floor pens at densities of 16, 18, 20 and 22 birds/m2 of floor space in an environmentally controll...

This work was part of a project designed to assess whether organic selenium (Se) can protect against the toxic effects of cadmium (Cd). A total of 300 1-day-old, as hatched, broilers were randomly distributed in four dietary treatments with five replicate pens per treatment. In T1 treatment, broilers were fed a diet with 0.3 mg/kg added Se, as Se-yeast, without added Cd; in T2, broilers were fe...

Preventing leg disorders in broilers, without changing their body weight at slaughter age and their rearing time is a challenge for poultry production. The method of prevention we studied consisted in alternating the distribution of different diets. This kind of diet schedule is called “sequential feeding”. The alternation of poorand rich-lysine diets was used in order to reduce early growth an...

Malabsorption syndrome (MAS) is a multifactorial disease that causes intestinal disorders in broilers due to infection of the gastrointestinal tract with different infectious agents. The exact aetiology is unknown, although several viruses are isolated from MAS affected chickens. None of these isolated infectious agents alone inducted the malabsorption syndrome. MAS in broilers is characterised...

Utilizing a moderate rearing temperature regimen, two trials were conducted to determine the effect of dietary energy level on the amount of abdominal fat deposited when broilers are grown to equal body weight by varying growth time. The most abdominal fat (2.29% average of live weight for male and females) was produced by broilers offered a diet calculated to contain 3325 ME kcal/kg. The least...

The effect of aqueous extract of aloe gel (10%w/v) on growth performance, antibody titer against ND, IB and IBD and faecal coccidial oocysts count following natural progression of coccidiosis in broilers reared at Peshawar was studied. One hundred and sixty, day old chicks were randomly allotted to four different groups, designated as A, B, C and D in an open sided house. Each group was replica...

this experiment was conducted to evaluate the effects of different commercial multi enzymes and nutrients levels of diets on performance and carcass traits of broilers. in this experiment 288 day old ross – 308 broilers (male and female) were used as (2*4) factors include: two levels of nutrients in diets (ross- 308 nutrients recommendation and 5% less than ross- 308 nutrients recommendation) a...

The crop is a known source of Salmonella and Campylobacter contamination. Previously, we evaluated lactic acid in the drinking water during a simulated pretransport feed withdrawal (FW) and reported 0.44% lactic acid significantly (P < 0.05) reduced the number of Salmonella recovered in market-age broiler crops. However, total consumption of the organic acid-treated drinking water was reduced. ...

This experiment was conducted to evaluate the effect of different levels alfalfa saponins on cholesterol metabolism in broilers. A total of 320 Arbor Acres (AA) broilers of 1 day-old were randomly allotted to 4 treatments with five replicates in each treatment, and with 16 broilers in each replicate. The experiment last 49 days. During the stage from 0 to 3 weeks, broilers in the control group ...

The enteropathogenicity of avian reoviruses (ARVs), isolated from chickens affected with malabsorption syndrome (MAS) from The Netherlands and Germany was studied. In the first trial seven different ARVs isolated from MAS cases were inoculated in 1-day-old specific pathogenic free (SPF) white leghorns. The pathogenicity was compared with 2 ARVs isolated from cases of tenosynovitis, namely refer...
