In this paper, we set the waiting time for elimination of levamisole residues at a safe level from tissues (muscles and organs) animals treated with 10%—oral solution. We studied depletion by high performance liquid chromatography mass spectrometer (limit quantification 2 μg/kg) in bovine, ovine, caprine, porcine poultry (chickens pigeons) after administration (10 mg levamisole/kg body weight c...

The objective of the study was to compare the carcass characteristics, meat quality, and blood parameters of slow and fast grown female broiler chickens fed in organic or conventional production system. The two genotypes tested were medium slow-growing chickens (SG, Hubbard Red JA) and commercial fast-growing chickens (FG, Ross 308). Both genotypes (each represented by 400 chickens) were divide...

fulani ecotype chickens (fec) and yoruba ecotype chickens (yec) are the two major types of indigenous chickens in nigeria. they subsist under traditional animal husbandry and are thus liable to indiscriminate mating and consequently to loss of genetic diversity. fulani ecotype chickens (fec) and yoruba ecotype chickens (yec) were investigated to determine genetic variation at transferrin locus ...

Lipid digestion, absorption and transport The processes of digestion and absorption in chickens are similar to those in mammals (see Annison, 1971). However, lipid transport differs between birds and mammals because in chickens the absorbed lipid enters the portal blood system directly as very-low-density lipoproteins, whereas in mammals it passes into the lymph as chylomicra; in chickens the v...

The prevalence of Toxoplasma gondii in free range chickens is a good indicator of the prevalence of T. gondii oocysts in the environment because chickens feed from the ground. In the present study, prevalence of T. gondii in 121 free range chickens (Gallus domesticus) and 19 ducks (Anas sp.) from a rural area surrounding Giza, Egypt was assessed. Blood, heart, and brain from each animal were ex...

Short-term feed preferences were studied in individually caged chickens fed sequentially in order to understand a previously described imbalance in the intake of diets offered. Sequential feeding (SF) was carried out for four 48 h cycles in male broiler chickens. The diets varied in energy (2800 (E-) and 3200 kcal/kg (E+)) and protein (230 (P+) and 150 g/kg (P-)) contents. SF was compared to st...

Background: Toxoplasma gondii, as an important food-borne protozoan parasite, occurs widely in humans and animals including domestic poultry throughout the world. The goal of this survey was to determine prevalence rate of T. gondii in free-ranging chickens sold in Tunis, Tunisia. Methods: In the present study, the prevalence of T. gondii in 40 free-range chickens (Gallus domesticus) marketed ...

Hydropericardium syndrome and inclusion body hepatitis, together called hydropericardium-hepatitis syndrome, are acute infectious diseases found in chickens. These diseases are caused primarily by fowl adenovirus serotype 4 (FAdV-4) strains. In this study, we isolated a FAdV-4 strain (SD0828) from clinically diseased chickens and phylogenetically analyzed the L1 loops of the hexon protein seque...

Objective: Indiscriminate use of antibiotics in poultry farms increases the chance antibiotic-resistant and ESBL producing bacteria Bangladesh. Therefore, study was undertaken to detect extended-spectrum β-lactamase (ESBL) Escherichia coli (E. coli) chickens. 
 Materials methods: A total 60 cloacal swab samples (20 from commercial layer, 20 broiler, Sonali chickens) were collected Rajshahi...

Runting and stunting syndrome (RSS), which is characterized by lower body weight, widely occurs in broilers. Some RSS chickens simply exhibit slow growth without pathological changes. An increasing number of studies indicate that broiler strains differ in susceptibility to infectious diseases, most likely due to their genetic differences. The objective of this study was to detect the differenti...
