Campylobacteriosis is the most frequent zoonotic disease in humans worldwide, and the contaminated poultry meat by Campylobacter jejuni can be considered one of the important sources of enteric infections in humans. The use of probiotics, which can help to improve the natural defense of animals against pathogenic bacteria, is an alternative and effective approach to antibiotic administration fo...

In the present study, a series of experiments were conducted to evaluate the ability of a combination of 3 ATCC lactobacilli (LAB3) or a commercially available probiotic culture (PROB) to reduce Salmonella enterica serovar Enteritidis (Salmonella Enteritidis) in broiler chicks. Additionally, we varied the timing of PROB administration in relationship to Salmonella challenge and determined the i...

BACKGROUND The interaction between the effects of exogenous neurotransmitters and dietary composition on appetite regulation in nonmammalian species is unclear. OBJECTIVE The objective of this study was to determine the effects of exogenous prolactin-releasing peptide (PrRP) and dietary macronutrient composition on food intake regulation in broiler chicks. METHODS Three isocaloric diets wer...

Phytogenic feed additives are used as antibacterial, anti-inflammatory and performance enhancer in the nutrition of broiler chicks. In present study, it was aimed to investigate effects usage phytogenic which an alternative antibiotics broilers at different levels rations, on morphology duodenum ileum. For this purpose, 48 male ROSS-308 one-day-old chicks were study. Chicks with a body weight 4...

Aims: This study seeks to evaluate the growth performance and physiological response of broiler chickens brooded with blue, black, white green side-curtains. It is essential ensure that thermal conditions within poultry building are controlled most especially in tropical climate where temperature observed exceed thermoneutral zones chickens. During brooding stage chicks, suitable relative humid...

Broilers with lower hatching weight (HW) present poorer performance than those with high HW, but there is limited research on the growth regulation of broilers with lower HW. The objective of this study was to investigate the effect of dietary methionine (Met) levels on the growth performance and breast muscle yield of broilers with different HW and underlying mechanisms. A total of 192 one-day...

The present study was done to clarify the relationship between the amount of dietary protein given to, and the gut microflora of, the host. Day-old chicks were given diets containing three concentrations of dietary protein (50, 200 and 400 g/kg) for 14 d. Body-weight gain, food consumption, body consumption, and protein and energy utilization were measured. There was no difference in body-weigh...

In recent years, researchers have given emphasis on the differences in physiological parameters between early and late hatched chicks within a hatch window. Considering the importance of intestine development in newly hatched chicks, however, changes in gene expression of nutrient transporters in the jejunum of early hatched chicks within a hatch window have not been studied yet. This study was...

Avian paramyxoviruses (APMV) are divided into nine serotypes. Newcastle disease virus (APMV-1) is the most extensively characterized, while relatively little information is available for the other APMV serotypes. In the present study, we examined the pathogenicity of two divergent strains of APMV-3, Netherlands and Wisconsin, in (i) 9-day-old embryonated chicken eggs, (ii) 1-day-old specific pa...

 To determine the neuropharmacological activity of the leaf extract of Croton zambesicus in mice and chicks. The effect of aqueous leaf extract of Croton zambesicus on thiopental sodium – induced sleeping time in mice, on gross locomotor activity (GLA) in 2-day old chicks and effect of extract on apomorphine - induced stereotyped behavior in chicks were evaluated. The a...
