The dilution of commercial broiler feed with copra meal (CM), palm kernel (PKM) and cassava leaf (CLM) enzyme supplementation was investigated. Two hundred eighty 7-day old Cobb 500 broilers were fed alone or diluted the test ingredients without enzyme. There no interaction effects (p>0.05) on intake (FI) weight gain (WG). Poorer (p<0.05) conversion ratio (FCR) observed diet diets from 22-42 d,...

background and objectives: the aim of our study was to characterize gizzard lactobacillus fermentum-group strains on the basis of their phenotypic profiles regarding characteristics of lactobacilli. in addition, their in vitro potential probiotic properties were evaluated. materials and methods: the lactic acid bacteria were isolated and identified from gizzard contents of algerian local poultr...

three adult pigeons (columbia livia) belonging to a pigeon farm in mashhad area were submitted topoultry clinic of school of veterinary medicine for post-mortem inspection. the farm had 150 adult pigeonsand a number of them suffered from a chronic disease with body weight loss, diarrhoea and weakness. atnecropsy, slight to extreme enlargement with distortion were observed in gizzards of all car...

We carried out an observational and experimental study to decipher how resource characteristics, in interaction with the predator's phenotype, constrain a fitness-determining performance measure, i.e. refuelling in a migrant bird. Two subspecies of red knot (Calidris canutus rogersi and C. c. piersmai) use northern Bohai Bay, Yellow Sea, China, for the final prebreeding stopover, during their 1...

Proximate (moisture, protein, total fat, total ash) and mineral (K, P, Na, Mg, Ca, Zn, Fe, Cu and Mn) composition of chicken giblets (heart, liver and gizzard) were investigated. Phosphorous content, as well as proximate composition, were determined according to recommended ISO methods. The content of all elements, except phosphorus, of the giblets tissues were determined using inductively coup...

This experiment was performed to investigate the effects of exogenous xylanase supplementation on performance, nutrient digestibility and the degradation of non-starch polysaccharides (NSP) in different sections of the gastrointestinal tract (GIT) of broilers fed wheat-based diets. A total of 120 7-day-old Arbor Acres broiler chicks were randomly allotted to two wheat-based experimental diets s...

Contamination of food producing animals by veterinary drug residues, particularly quinolones, is an essential issue in food safety that causes increasing concern in consumers. The aim of this study was to investigate the occurrence of enrofloxacin and its main metabolite, ciprofloxacin, in chicken tissue samples slaughtered in Tabriz, Iran. Totally 250 samples including liver, muscle, gizzard, ...

Nutritional regulation of gene expression associated with growth and feeding behavior in avian species can become an important technique to improve poultry production according to the supply of nutrients in the diet. Insulin-like growth factor-I (IGF-I) found in chickens has been characterized to be a 70 amino acid polypeptide and plays an important role in growth and metabolism. Although it is...
