To calculate partial and total productivity of production factors in broiler farms in Yazd province, 72 manufacturing units were selected based on simple random sampling method and their information and statistics were collected for one production period in the second half of 2013. To measure productivity, the Cobb-Douglas production function was estimated using classic and fuzzy regression met...

BACKGROUND Vancomycin resistant enterococci (VRE) in Swedish broiler production has been shown to persist at farms between batches. The aim of this study was therefore to determine the possibility to eliminate VRE by disinfection of compartments in broiler houses as a proof of concept. FINDINGS VRE could not be detected in environmental samples from the disinfected test compartments in the br...

The cost and return analysis of different sizes of broiler farms in the Punjab state has been carried out based on the primary data collected from 140 broiler farmers for the period March 2008 to February 2009 in three districts, viz. Ludhiana, Hoshiarpur and Muktsar. The study has shown that the total fixed investments per bird have been highest on small farms, followed by medium and large far...

evaporative cooling system and high air velocity management are important tools in alleviating the effects of heat stress on broilers performance during hot weather. in this study, technical and economical aspects of ventilation in varamin township broiler farms during summer were investigated. data were obtained from completed questionnaires through 20 broiler houses. information of air veloci...

Escherichia coli strains resistant to extended-spectrum cephalosporins (ESC) are widely distributed in Norwegian broiler production, and the majority harbor transferable IncK or IncI1 plasmids carrying blaCMY-2 Persistent occurrence in broiler farms may occur through the survival of ESC-resistant E. coli strains in the farm environment, or by transfer and maintenance of resistance plasmids with...

The experiment was conducted to determine the effect of artificial insemination (AI) on different production parameter in Hubbard Classic Broiler breeder parent stock. A total number of 300 female and 30 male Hubbard Classic broiler breeder parent stock birds were used as experimental animals and parameter recorded are: Health condition and body weight of birds, % of Production, % Hatchability,...

Effect of photoperiod on age and BW at attainment of mature semen production was examined in males of lines selected for high (HL) and low (LL) threshold BW at onset of lay, and in males of a commercial Cornish male line (MC), a commercial broiler breeder female line cross (BX), and a commercial layer cross (LX). Photoperiod treatments were: I, increasing natural spring light; and D, steadily d...

With increasing disparity between broiler breeder target weights and broiler growth potential, maintenance energy requirements have become a larger proportion of total broiler breeder energy intake. Because energy is partitioned to growth and egg production at a lower priority than maintenance, accurate prediction of maintenance energy requirements is important for practical broiler breeder fee...

The measurement of feed efficiency in the broiler industry is one of pri­ mary measurements used to monitor and evaluate broiler performance. It has a significant impact on the competitiveness in the marketplace as nearly 70% of the cost of raising a commercial broiler is feed. Although feed costs may shift up or down, it will always represent the highest input cost in commercial poultry produc...
