analyzing efficiency in each economic sector to adopt policies for optimal use of production factors and avoid wasting resources is important. in this study, in order to have a more comprehensive evaluation of the performance of each unit, efficiency of broiler firms was measured using bounded data envelopment analysis which determines position of each unit relative to efficient and inefficient...

This study was conducted to assay the use of Saturejahortensis L. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. Four hundred and twenty day old broiler chickens (Ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. Experimental treatments included: 1) control, 2) Tween (a solvent for...

A total of 1905 mixed sex day old broiler chickens were reared in environmentally controlled house for 5 weeks to study the production performance of chicks by feeding different levels of canola meal in their diets. The chickens were randomly allocated to five dietary treatment groups ( A, B, C, D and E ) having three replicates of 127 birds in each group. Groups A, B, C, D and E were fed pelle...

An experimental study was carried over a period of 42 days using 160 day-old commercial broiler chicks (Ven Cobb) to study the effect of copper and flavomycin as feed additives on growth performance in broiler chicken. The birds were divided into four groups with four replicates of ten chicks in each replicate. The treatment (T1) was control with standard broiler ration and Cu as CuSO4 at 100 p...

High temperature is one of the key environmental stressors affecting broiler production efficiency and meat yield. Knowledge of broiler self-regulation mechanisms under heat stress is important for the modern scale of poultry breeding. In the present study, the SWATH strategy was employed to investigate the temporal response of the broiler liver to heat stress. A total of 4,271 proteins were id...

Abnormal animal behaviour and reduced growth rate in a broiler house are just a few signs that can indicate an undesired situation, such as diseases, technical malfunctioning in feeding and drinking lines and suboptimal management procedures. It is important that the problems be detected in an early stage to avoid harming the welfare or the production of broilers. In this paper, an automated me...

Nowadays, the poultry industry gives a lot of importance to costs management at all the steps of production. In broilers, the production of hatching eggs or Day-Old Chick (DOC) does not represent a high proportion of the overall cost of production per kg of bird slaughtered. Nevertheless, the performance of broiler breeder is looked with a lot of attention, and the number of saleable chicks per...

background: coccidian infection in poultry is the most common infection in the world and is the cause of mortality and great economic losses in poultry production. objectives: this study was aimed to determine the frequency and eimeria species diversity in broiler farms of hamadan suburb, iran. methods: a total of 16 broiler farms were randomly selected with different production age in 2012. th...

Broiler feed conversion rate (FCR) optimization reduces the amount of feed, water, and electricity required to produce a mature broiler, where temperature control is one most influential factors. Iterative learning (ILC) provides potential solution given repeated nature production process, as it has been especially developed for systems that make executions same finite duration task. Dynamic ne...

this study was conducted to determine the effects of increasing lighting after peak production on eggs production and hatchable eggs in broiler breeder hubbard f15. in this research we used from 4 growing saloons, that in per saloons were 5250 hubbards broiler breeder hens. in this experiment we used by line design way of glm for analysed data, that we considered the effects of two parameters, ...
