A diet for broiler chickens that provides the nutrients essential for maintenance and growth of the flock as a whole may also have chemical and physical properties which are detrimental to the processes of ingestion, digestion, absorption, transport and utilization of nutrients. The digestive capacity of the chicken can be modelled according to interactions between feed– related and bird–relate...

The aim of the present study was to evaluate the effect of feeding four levels of tuna oil on performance and fatty acid (FA) profiles of broiler chicken meat. 240 Ross broiler chickens were randomly assigned to 20 pens and divided into four treatments: 0%, 0.75%, 1%, and 1.25% of tuna oil. At 49 days, breast and legs-thighs muscles were processed for FA analysis. Concentrations of FA in legs a...

Salmonella enterica ssp. enterica is a leading cause of bacterial food-borne disease outbreaks worldwide and is also an economic burden particularly in Reunion Island because its population consumes large amounts of chicken and cooks 100% chicken sausages (35 kg per capita per year). The aim of this study was to investigate the epidemiology of Salmonella Typhimurium and Salmonella 1,4,[5],12:i:...

Campylobacter contaminated broiler chicken meat is an important source of foodborne gastroenteritis and poses a serious health burden in industrialized countries. Broiler chickens are commonly regarded as a natural host for this zoonotic pathogen and infected birds carry a very high C. jejuni load in their gastrointestinal tract, especially the ceca. This eventually results in contaminated carc...

One of the most extraordinary results of selective breeding is the modern broiler chicken, whose phenotypic attributes reflect its genetic success. Unfortunately, leg health issues and poor walking ability are prevalent in the broiler population, with the exact aetiopathogenesis unknown. Here we present a biomechanical analysis of the gait dynamics of the modern broiler and its two pureline com...

The aim of this study was to test the hypothesis that valuable on-farm outcome measures of broiler (meat) chicken welfare can be derived from optical flow statistics of flock movements recorded on video or CCTV inside commercial broiler houses. ‘Optical flow’ describes the velocity of imagemotion across an eye or camera and statistical patterns can be derived automatically and continuously thro...

Results of examinations of the prenatal dynamic of development of skeletal musculature of chicken have been presented in this paper. Eggs of two types of chicken hybrids were incubated – broiler (Ross 308) and layer (Hy-Line Brown). Samples were taken in determined intervals. For the analyses of samples, light and scanning electron microscopy were used. Morphological characteristics of skeletal...

Background Broiler chickens have properties as meat-producing poultry and produce meat with soft fiber quality. Broiler’s embryo needs to be given attention, especially against disease. The purpose of the study was observe trend research topic external factors which could affect embryo’s growth broiler. Method<ns4:b...

The NRC selenium (Se) requirement for broiler chicks is 0.15 μg Se/g diet, based primarily on weight gain and feed intake studies reported in 1986. To determine Se requirements in today's rapidly growing broiler chick, day-old male chicks were fed Se-deficient basal diets supplemented with graded levels of Se (0, 0.025, 0.05, 0.075, 0.1, 0.2, 0.3, 0.5, 0.75, and 1.0 μg Se/g) as Na2SeO3 (5/treat...

Age has significant impact on hepatic cytochrome P450 (CYP450) systems in animals. Ross 708 broiler chicken is a breed of chicken with fast growth characteristics. Cytochrome P450 in the livers of Ross 708 broiler chicken of different ages has been investigated. The birds were raised under standard husbandry conditions. A certain number of chickens was randomly sampled weekly for liver collecti...
